This FAQ is shared between + comp.mail.sendmail and the Sendmail V8 distribution. It should + be read by anyone who wishes to post to comp.mail.sendmail, or + anyone having questions about the newsgroup itself. + +Archive-name: mail/sendmail-faq +Posting-Frequency: monthly (first Monday) + + +[The most recent copy of this document can be obtained via anonymous +FTP from rtfm.mit.edu in /pub/usenet/news.answers/mail/sendmail-faq. +If you do not have access to anonymous FTP, you can retrieve it by +sending email to mail-server@rtfm.mit.edu with the command "send +usenet/news.answers/mail/sendmail-faq" in the message.] + + + + Sendmail Version 8 + Frequently Asked Questions + Last updated 9/17/95 + + +This FAQ is specific to Version 8.6.10 of sendmail. Other questions, +particularly regarding compilation and configuration, are answered in +src/READ_ME and cf/README (found in the V8 sendmail distribution). + +This is also the official FAQ for the Usenet newsgroup +comp.mail.sendmail. + +====================================================================== +BEFORE YOU GO ANY FURTHER +====================================================================== + + * What do you wish everyone would do before sending you mail or + posting to comp.mail.sendmail? + + Read this FAQ completely. Read src/READ_ME and cf/README + completely. Read the books written to help with common + problems such as compilation and installation, configuration, + security issues, etc.... Ask themselves if their question + hasn't already been answered. +---------------------------------------------------------------------- + * How can I be sure if this is the right place to look for answers + to my questions? + + 1. Do you know, for a fact, that the question is related to + sendmail V8? + + 2. Do you know, for a fact, that the question is related to an + older version of sendmail? + + 3. Is the question about a sendmail-like program (e.g., Smail, + Zmailer, MMDF, etc...)? + + 4. Is the question about an SMTP Gateway product for a LAN + mail package (e.g., cc:Mail, MS-Mail, WordPerfect + Office/GroupWise, etc...)? + + If you answered "yes" to the question #1, then this is the + right place. + + If you answered "yes" to questions #2 or #3, then you should + seriously consider upgrading to the most recent version of + sendmail V8. + + For question #2, If you're going to continue using an older + version of sendmail, you may not find much help and will + probably get some responses that amount to "Get V8". + Otherwise, this is probably the best place to look for + answers. + + If you answered "yes" to question #3 and are not going to + upgrade to sendmail V8, then this is probably not the right + place to look. + + If you answered "yes" to question #4, then this is almost + certainly not the right place to look. + + For questions #3 and #4, try looking around elsewhere in the + "comp.mail.*" hierarchy for a more appropriate newsgroup. + For example, you might want to try posting to comp.mail.misc + or comp.mail.smail. + + If you couldn't answer "yes" to any of the above questions, + then you're DEFINITELY in the wrong place. For the sake of + your sanity and ego, not to mention avoiding the waste of + your time and ours, try asking your System or E-Mail + Administrator(s) before you post any questions publicly. +---------------------------------------------------------------------- + * Where can I find the latest version of this FAQ? + + It is included in the most recent Version 8 distribution of + sendmail (described below), as well as via anonymous FTP from + rtfm.mit.edu in /pub/usenet/news.answers/mail/sendmail-faq. + If you do not have access to anonymous FTP, you can retrieve + it by sending email to mail-server@rtfm.mit.edu with the + command "send usenet/news.answers/mail/sendmail-faq" in the + message. +---------------------------------------------------------------------- + * I don't have access to Usenet news. Can I still get access to + comp.mail.sendmail? + + Yes. Send email to mxt@dl.ac.uk with the command "sub + comp-news.comp.mail.sendmail <full-US-ordered-email-address>" + in the message. + + E-mail you want posted on comp.mail.sendmail should be sent + to comp-mail-sendmail@dl.ac.uk +---------------------------------------------------------------------- + * I have sendmail-related DNS questions. Where should I ask them? + + Depending on how deeply they get into the DNS, they can be + asked here. However, you'll probably be told that you should + send them to the Info-BIND mailing list (if the question is + specific to that program) or to the Usenet newsgroup + comp.protocols.tcp-ip.domains (DNS in general). +---------------------------------------------------------------------- + * How do I subscribe to either of these? + + For comp.protocols.tcp-ip.domains, you have to be on Usenet. + They don't have a news-to-mail gateway yet. + + For the Info-BIND mailing list, send email to + bind-request@uunet.uu.net with the command "subscribe" in the + message. Submissions should be sent to bind@uunet.uu.net + +====================================================================== +GENERAL QUESTIONS +====================================================================== + + * Where can I get Version 8? + + Via anonymous FTP from FTP.CS.Berkeley.EDU in /ucb/sendmail. +---------------------------------------------------------------------- + * What are the differences between Version 8 and other versions? + + See doc/changes/changes.me in the sendmail distribution. +---------------------------------------------------------------------- + * What happened to sendmail 6.x and 7.x? + + When a new (Alpha/Beta) version of sendmail was released, it + was changed to Release 6. Development continued in that tree + until 4.4BSD was released, when everything on the 4.4 tape + was set to be version 8.1. Version 7.x never existed. +---------------------------------------------------------------------- + * What books are available describing sendmail? + + There is one book available devoted to sendmail: + + Costales, Allman, and Rickert, _Sendmail_. O'Reilly & + Associates. + + Several books have sendmail chapters, for example: + + Nemeth, Snyder, and Seebass, _Unix System Administration + Handbook_. Prentice-Hall. + Carl-Mitchell and Quarterman, _Practical Internetworking with + TCP/IP and UNIX_. Addison-Wesley. + Hunt, _TCP/IP Network Administration_. O'Reilly & Associates. + + Another book about sendmail is due out "soon": + + Avolio & Vixie, _Sendmail Theory and Practice_. Digital + Press (release date unknown). + + For details on sendmail-related DNS issues, consult: + + Liu and Albitz, _DNS and BIND_. O'Reilly & Associates. + + For details on UUCP, see: + + O'Reilly and Todino, _Managing UUCP and Usenet_. + O'Reilly & Associates. + +====================================================================== +COMPILING AND INSTALLING SENDMAIL 8 +====================================================================== + + * Version 8 requires a new version of "make". Where can I get this? + + Actually, Version 8 does not require a new version of "make". + It includes a collection of Makefiles for different architectures, + only one or two of which require the new "make". For a supported + architecture, use ``sh makesendmail''. If you are porting to a + new architecture, start with Makefile.dist. + + If you really do want the new make, it is available on any of + the BSD Net2 or 4.4-Lite distribution sites. These include: + + ftp.uu.net /systems/unix/bsd-sources + gatekeeper.dec.com /.0/BSD/net2 + ucquais.cba.uc.edu /pub/net2 + ftp.luth.se /pub/unix/4.3bsd/net2 + + Diffs and instructions for building this version of make + under SunOS 4.1.x are available on ftp.css.itd.umich.edu in + /pub/systems/sun/Net2-make.sun4.diff.Z. A patchkit for + Ultrix is on ftp.vix.com in /pub/patches/pmake-for-ultrix.Z. + Patches for AIX 3.2.4 are available on ftp.uni-stuttgart.de + in /sw/src/patches/bsd-make-rus-patches. + + There is also a Linux version available on the main Linux + distribution sites as pmake; this version is included as + standard with the current Slackware distributions. +---------------------------------------------------------------------- + * What macro package do I use to format the V8 man pages? + + The BSD group switched over the the ``mandoc'' macros for the + 4.4 release. These include more hooks designed for hypertext + handling. However, new man pages won't format under the old + man macros. Fortunately, old man pages will format under the + new mandoc macros. + + Get the new macros with the BSD Net2 or 4.4-Lite release (see + above for locations; for example, on FTP.UU.NET the files + /system/unix/bsd-sources/share/tmac/me/strip/sed and + /system/unix/bsd-sources/share/tmac/* are what you need). + + This macro set is also included with newer versions of groff. +---------------------------------------------------------------------- + * What modes should be used when installing sendmail? + + The sendmail binary should be owned by root, mode 4755. + The queue directory should be owned by root, with a mode + between 700 and 755. Under no circumstances should + it be group or other writable! + The sendmail config file should be owned by root, mode 644. + The aliases file should generally be owned by one trusted + user and writable only by that user, although it is + not unreasonable to have it group writable by a + "sysadmin" group. It should not be world writable. + The aliases database files (aliases.db or aliases.{pag,dir} + depending on what database format you compile with) + should be owned by root, mode 644. + +====================================================================== +CONFIGURATION QUESTIONS +====================================================================== + + * How do I make all my addresses appear to be from a single host? + + Using the V8 configuration macros, use: + + MASQUERADE_AS(my.dom.ain) + + This will cause all addresses to be sent out as being from + the indicated domain. +---------------------------------------------------------------------- + * How do I rewrite my From: lines to read ``First_Last@My.Domain''? + + There are a couple of ways of doing this. This describes + using the "user database" code. This is still experimental, + and was intended for a different purpose -- however, it does + work with a bit of care. It does require that you have the + Berkeley "db" package installed (it won't work with DBM). + + First, create your input file. This should have lines like: + + loginname:mailname First_Last + First_Last:maildrop loginname + + Install it in (say) /etc/userdb. Create the database: + + makemap btree /etc/userdb.db < /etc/userdb + + You can then create a config file that uses this. You will + have to include the following in your .mc file: + + define(confUSERDB_SPEC, /etc/userdb.db) + FEATURE(notsticky) +---------------------------------------------------------------------- + * So what was the user database feature intended for? + + The intent was to have all information for a given user + (where the user is the unique login name, not an inherently + non-unique full name) in one place. This would include phone + numbers, addresses, and so forth. The "maildrop" feature is + because Berkeley does not use a centralized mail server + (there are a number of reasons for this that are mostly + historic), and so we need to know where each user gets his or + her mail delivered -- i.e., the mail drop. + + We are in the process of setting up our environment so that + mail sent to an unqualified "name" goes to that person's + preferred maildrop; mail sent to "name@host" goes to that + host. The purpose of "FEATURE(notsticky)" is to cause + "name@host" to be looked up in the user database for delivery + to the maildrop. +---------------------------------------------------------------------- + * Why are you so hostile to using full names for e-mail addresses? + + Because full names are not unique. For example, the computer + community has two Andy Tannenbaums and two Peter Deutsches. + At one time, Bell Labs had two Stephen R. Bournes with + offices a few doors apart. You can create alternative + addresses (e.g., Stephen_R_Bourne_2), but that's even worse + -- which one of them has to have their name desecrated in + this way? And you can bet that one of them will get most of + the other person's e-mail. + + So called "full names" are just an attempt to create longer + versions of unique names. Rather that lulling people into a + sense of security, I'd rather that it be clear that these + handles are arbitrary. People should use good user agents + that have alias mappings so that they can attach arbitrary + names for their personal use to those with whom they + correspond (such as the MH alias file). + + Even worse is fuzzy matching in e-mail -- this can make good + addresses turn bad. For example, Eric Allman is currently + (to the best of our knowledge) the only ``Allman'' at + Berkeley, so mail sent to "Allman@Berkeley.EDU" should get to + him. But if another Allman ever appears, this address could + suddenly become ambiguous. He's been the only Allman at + Berkeley for over fifteen years -- to suddenly have this + "good address" bounce mail because it is ambiguous would be a + heinous wrong. + + Finger services should be as fuzzy as possible (within + reason, of course). Mail services should be unique. +---------------------------------------------------------------------- + * Should I use a wildcard MX for my domain? + + If at all possible, no. + + Wildcard MX records have lots of semantic "gotcha"s. For + example, they will match a host "unknown.your.domain" -- if + you don't explicitly test for unknown hosts in your domain, + you will get "config error: mail loops back to myself" + errors. + + See RFCs 1535-1537 for more detail and other related (or + common) problems. +---------------------------------------------------------------------- + * How can I get sendmail to process messages sent to an account and + send the results back to the originator? + + This is a local mailer issue, not a sendmail issue. + Depending on what you're doing, look at procmail (mentioned + again below), ftpmail, or Majordomo. + + Check your local archie server to see what machine(s) nearest + you have the most recent versions of these programs. +---------------------------------------------------------------------- + * How can I get sendmail to deliver local mail to $HOME/.mail + instead of into /usr/spool/mail (or /usr/mail)? + + Again, this is a local mailer issue, not a sendmail issue. + Either modify your local mailer (source code will be + required) or change the program called in the "local" mailer + configuration description to be a new program that does this + local delivery. One program that is capable of doing this is + "procmail", although there are probably many others as well. + + You might be interested in reading the paper ``HLFSD: + Delivering Email to your $HOME'' available in the Proceedings + of the USENIX System Administration (LISA VII) Conference + (November 1993). This is also available via public FTP from + ftp.cs.columbia.edu in /pub/hlfsd/{README.hlfsd,hlfsd.ps}. +---------------------------------------------------------------------- + * I'm trying to to get my mail to go into queue only mode, and it + delivers the mail interactively anyway. (Or, I'm trying to use + the "don't deliver to expensive mailer" flag, and it delivers the + mail interactively anyway.) I can see it does it: here's the + output of "sendmail -v foo@somehost" (or Mail -v or equivalent). + + The -v flag to sendmail (which is implied by the -v flag to + Mail and other programs in that family) tells sendmail to + watch the transaction. Since you have explicitly asked to + see what's going on, it assumes that you do not want to to + auto-queue, and turns that feature off. Remove the -v flag + and use a "tail -f" of the log instead to see what's going + on. + + If you are trying to use the "don't deliver to expensive + mailer" flag (mailer flag "e"), be sure you also turn on + global option "c" -- otherwise it ignores the mailer flag. +---------------------------------------------------------------------- + * There are four UUCP mailers listed in the configuration files. + Which one should I use? + + The choice is partly a matter of local preferences and what + is running at the other end of your UUCP connection. Unlike + good protocols that define what will go over the wire, UUCP + uses the policy that you should do what is right for the + other end; if they change, you have to change. This makes it + hard to do the right thing, and discourages people from + updating their software. In general, if you can avoid UUCP, + please do. + + If you can't avoid it, you'll have to find the version that + is closest to what the other end accepts. Following is a + summary of the UUCP mailers available. + + uucp-old (obsolete name: "uucp") + This is the oldest, the worst (but the closest to UUCP) way + of sending messages across UUCP connections. It does + bangify everything and prepends $U (your UUCP name) to the + sender's address (which can already be a bang path + itself). It can only send to one address at a time, so it + spends a lot of time copying duplicates of messages. Avoid + this if at all possible. + + uucp-new (obsolete name: "suucp") + The same as above, except that it assumes that in one rmail + command you can specify several recipients. It still has a + lot of other problems. + + uucp-dom + This UUCP mailer keeps everything as domain addresses. + Basically, it uses the SMTP mailer rewriting rules. + + Unfortunately, a lot of UUCP mailer transport agents + require bangified addresses in the envelope, although you + can use domain-based addresses in the message header. (The + envelope shows up as the From_ line on UNIX mail.) So.... + + uucp-uudom + This is a cross between uucp-new (for the envelope + addresses) and uucp-dom (for the header addresses). It + bangifies the envelope sender (From_ line in messages) + without adding the local hostname, unless there is no host + name on the address at all (e.g., "wolf") or the host + component is a UUCP host name instead of a domain name + ("somehost!wolf" instead of "some.dom.ain!wolf"). + + Examples: + + We are on host grasp.insa-lyon.fr (UUCP host name "grasp"). + The following summarizes the sender rewriting for various + mailers. + + Mailer sender rewriting in the envelope + ------ ------ ------------------------- + uucp-{old,new} wolf grasp!wolf + uucp-dom wolf wolf@grasp.insa-lyon.fr + uucp-uudom wolf grasp.insa-lyon.fr!wolf + + uucp-{old,new} wolf@fr.net grasp!fr.net!wolf + uucp-dom wolf@fr.net wolf@fr.net + uucp-uudom wolf@fr.net fr.net!wolf + + uucp-{old,new} somehost!wolf grasp!somehost!wolf + uucp-dom somehost!wolf somehost!wolf@grasp.insa-lyon.fr + uucp-uudom somehost!wolf grasp.insa-lyon.fr!somehost!wolf + +====================================================================== +RESOLVING PROBLEMS +====================================================================== + + * When I compile, I get "undefined symbol inet_aton" messages. + + You've probably replaced your resolver with the version from + BIND 4.9.3. You need to compile with -l44bsd in order to get + the additional routines. +---------------------------------------------------------------------- + * I'm getting "Local configuration error" messages, such as: + + 553 relay.domain.net config error: mail loops back to myself + 554 <user@domain.net>... Local configuration error + + How can I solve this problem? + + You have asked mail to the domain (e.g., domain.net) to be + forwarded to a specific host (in this case, relay.domain.net) + by using an MX record, but the relay machine doesn't + recognize itself as domain.net. Add domain.net to + /etc/sendmail.cw (if you are using FEATURE(use_cw_file)) or + add "Cw domain.net" to your configuration file. + + IMPORTANT: Be sure you kill and restart the sendmail daemon + after you change the configuration file (for ANY change in + the configuration, not just this one): + + kill `head -1 /etc/sendmail.pid` + sh -c "`tail -1 /etc/sendmail.pid`" + + NOTA BENE: kill -1 does not work! +---------------------------------------------------------------------- + * When I use sendmail V8 with a Sun config file I get lines like: + + /etc/sendmail.cf: line 273: replacement $3 out of bounds + + the line in question reads: + + R$*<@$%y>$* $1<@$2.LOCAL>$3 user@ether + + what does this mean? How do I fix it? + + V8 doesn't recognize the Sun "$%y" syntax, so as far as it is + concerned, there is only a $1 and a $2 (but no $3) in this + line. Read Rick McCarty's paper on "Converting Standard Sun + Config Files to Sendmail Version 8", in the contrib directory + (file "converting.sun.configs") on the sendmail distribution + for a full discussion of how to do this. +---------------------------------------------------------------------- + * When I use sendmail V8 on a Sun, I sometimes get lines like: + + /etc/sendmail.cf: line 445: bad ruleset 96 (50 max) + + what does this mean? How do I fix it? + + You're somehow trying to start up the old Sun sendmail (or + sendmail.mx) with a sendmail V8 config file, which Sun's + sendmail doesn't like. Check your /etc/rc.local, any + procedures that have been created to stop and re-start the + sendmail processes, etc.... Make sure that you've switched + everything over to using the new sendmail. To keep this + problem from ever happening again, try the following: + + mv /usr/lib/sendmail /usr/lib/sendmail.old + ln -s /usr/local/lib/sendmail.v8 /usr/lib/sendmail + mv /usr/lib/sendmail.mx /usr/lib/sendmail.mx.old + ln -s /usr/local/lib/sendmail.v8 /usr/lib/sendmail.mx + chmod 0000 /usr/lib/sendmail.old + chmod 0000 /usr/lib/sendmail.mx.old + + Assuming you have installed sendmail V8 in /usr/local/lib. +---------------------------------------------------------------------- + * When I use sendmail V8 on an IBM RS/6000 running AIX, the system + resource controller always reports sendmail as "inoperative" even + though it is running. What's wrong? + + IBM's system resource controller is one of their "value + added" features to AIX -- it's not a Unix standard. You'll + need to either redefine the subsystem to use signals (see + chssys(1)) or dump the entire subsystem and invoke sendmail + in /etc/rc.tcpip or some other boot script. +---------------------------------------------------------------------- + * When I use sendmail V8 on an Intel x86 machine running Linux, I + have some problems. Specifically, I have.... + + The current versions of Linux are generally considered to be + great for hobbyists and anyone else who wants to learn Unix + inside and out, or wants to always have something to do, or + wants a machine for light-duty mostly personal use and not + high-volume multi-user purposes. + + However, for those who want a system that will just sit in + the background and work without a fuss handling thousands of + mail messages a day for lots of different users, it's not + (yet) stable enough to fit the bill. + + Unfortunately, there are no known shareware/freeware + implementations of any operating system that provides the + level of stability necessary to handle that kind of load + (i.e., there are no free lunches). + + If you're wedded to the Intel x86 platform and want to run + sendmail, we suggest you look at commercial implementations + of Unix such as Interactive, UnixWare, Solaris, or BSD/386 + (just a sample of the dozens of different versions of Unix + for Intel x86). + + Of all known vendor supported versions of Unix for Intel x86, + BSDI's BSD/386 is least expensive and the only one known to + currently ship with sendmail V8 pre-installed. Since sendmail + V8 is continuing to be developed at UC Berkeley, and BSD/386 + is a full BSD 4.4 implementation, this is obviously be the most + "native" sendmail V8 environment. +---------------------------------------------------------------------- + * When I use sendmail on an Intel x86 machine running OS/2, I have + some problems. Specifically, I have.... + + The OS/2 port of sendmail is known to have left out huge + chunks of the code and functionality of even much older + versions of sendmail, in large part because the underlying OS + just doesn't have the necessary hooks to make it happen. + This port is so broken that we make no attempt to provide any + kind of support for it. Try BSDI's BSD/386 instead. +---------------------------------------------------------------------- + * I'm connected to the network via a SLIP/PPP link. Sometimes my + sendmail process hangs (although it looks like part of the + message has been transfered). Everything else works. What's + wrong? + + Most likely, the problem isn't sendmail at all, but the low + level network connection. It's important that the MTU + (Maximum Transfer Unit) for the SLIP connection be set + properly at both ends. If they disagree, large packets will + be trashed and the connection will hang. +---------------------------------------------------------------------- + * I just upgraded to 8.x and suddenly I'm getting messages in my + syslog of the form "collect: I/O error on connection". What is + going wrong? + + Nothing. This is just a diagnosis of a condition that had + not been diagnosed before. If you are getting a lot of these + from a single host, there is probably some incompatibility + between 8.x and that host. If you get a lot of them in + general, you may have network problems that are causing + connections to get reset. +---------------------------------------------------------------------- + * I just upgraded to 8.x and now when my users try to forward their + mail to a program they get an "illegal shell" message and their + mail is not delivered. What's wrong? + + In order for people to be able to run a program from their + .forward file, 8.x insists that their shell (that is, the + shell listed for that user in the passwd entry) be a "valid" + shell, meaning a shell listed in /etc/shells. If /etc/shells + does not exist, a default list is used, typically consisting + of /bin/sh and /bin/csh. + + This is to support environments that may have NFS-shared + directories mounted on machines on which users do not have + login permission. For example, many people make their + file server inaccessible for performance or security + reasons; although users have directories, their shell on + the server is /usr/local/etc/nologin or some such. If you + allowed them to run programs anyway you might as well let + them log in. + + If you are willing to let users run programs from their + .forward file even though they cannot telnet or rsh in (as + might be reasonable if you run smrsh to control the list of + programs they can run) then add the line + + /SENDMAIL/ANY/SHELL/ + + to /etc/shells. This must be typed exactly as indicated, + in caps, with the trailing slash. NOTA BENE: DO NOT + list /usr/local/etc/nologin in /etc/shells -- this will + open up other security problems. +---------------------------------------------------------------------- + * I just upgraded to 8.x and suddenly connections to the SMTP port + take a long time. What is going wrong? + + It's probably something weird in your TCP implementation that + makes the IDENT code act oddly. On most systems V8 tries to + do a ``callback'' to the connecting host to get a validated + user name (see RFC 1413 for detail). If the connecting host + does not support such a service it will normally fail quickly + with "Connection refused", but certain kinds of packet + filters and certain TCP implementations just time out. + + To test this, set the IDENT timeout to zero using + ``OrIdent=0'' in the configuration file. This will + completely disable all use of the IDENT protocol. + + Another possible problem is that you have your name server + and/or resolver configured improperly. Make sure that all + "nameserver" entries in /etc/resolv.conf point to functional + servers. If you are running your own server make certain + that all the servers listed in your root cache (usually + called something like "/var/namedb/root.cache"; see your + /etc/named.boot file to get your value) are up to date. + Either of these can cause long delays. +---------------------------------------------------------------------- + * I just upgraded to 8.x and suddenly I get errors such as ``unknown + mailer error 5 -- mail: options MUST PRECEDE recipients.'' What is + going wrong? + + You need OSTYPE(systype) in your .mc file -- otherwise the + configurations use a default that probably disagrees with + your local mail system. See cf/README for details. +---------------------------------------------------------------------- + * Under V8, the "From " header gets mysteriously munged when I send + to an alias. + + ``It's not a bug, it's a feature.'' This happens when you + have a "owner-list" alias and you send to "list". V8 + propagates the owner information into the envelope sender + field (which appears as the "From " header on UNIX mail or as + the Return-Path: header) so that downstream errors are + properly returned to the mailing list owner instead of to the + sender. In order to make this appear as sensible as possible + to end users, I recommend making the owner point to a + "request" address -- for example: + + list: :include:/path/name/list.list + owner-list: list-request + list-request: eric + + This will make message sent to "list" come out as being "From + list-request" instead of "From eric". +---------------------------------------------------------------------- + * I am trying to use MASQUERADE_AS (or the user database) to + rewrite from addresses, and although it works in the From: header + line, it doesn't work in the envelope (e.g., the "From " line). + + Believe it or not, this is intentional. The interpretation + of the standards by the V8 development group was that this + was an inappropriate rewriting, and that if the rewriting + were incorrect at least the envelope would contain a valid + return address. Other people have since described scenarios + where the envelope cannot be correct without this rewriting, + so 8.7 will have an option to rewrite both header and + envelope. +---------------------------------------------------------------------- + * I want to run Sendmail version 8 on my DEC system, but you don't + have MAIL11V3 support in sendmail. How do I handle this? + + Get Paul Vixie's reimplementation of the mail11 protocol from + gatekeeper.dec.com in /pub/DEC/gwtools. + + Rumour has it that he will be fully integrating into sendmail + V8 what little is left of IDA sendmail that is not handled + (or handled as well) by V8. No additional information on + this project is currently available. +---------------------------------------------------------------------- + * Messages seem to disappear from my queue unsent. When I look in + the queue directory I see that they have been renamed from qf* to + Qf*, and sendmail doesn't see these. + + If you look closely you should find that the Qf files are + owned by users other than root. Since sendmail runs as root + it refuses to believe information in non-root-owned qf files, + and it renames them to Qf to get them out of the way and make + it easy for you to find. The usual cause of this is + twofold: first, you have the queue directory world writable + (which is probably a mistake -- this opens up other security + problems) and someone is calling sendmail with an "unsafe" + flag, usually a -o flag that sets an option that could + compromise security. When sendmail sees this it gives up + setuid root permissions. + + The usual solution is to not use the problematic flags. If + you must use them, you have to write a special queue + directory and have them processed by the same uid that + submitted the job in the first place. +---------------------------------------------------------------------- +@(#)FAQ 8.16 (Berkeley) 9/17/95 +Send updates to sendmail@sendmail.ORG. diff --git a/usr.sbin/sendmail/KNOWNBUGS b/usr.sbin/sendmail/KNOWNBUGS new file mode 100644 index 000000000000..f9020e7fb75e --- /dev/null +++ b/usr.sbin/sendmail/KNOWNBUGS @@ -0,0 +1,119 @@ + + + K N O W N B U G S I N S E N D M A I L + (for 8.7) + + +The following are bugs or deficiencies in sendmail that I am aware of +but which have not been fixed in the current release.

For descriptions of bugs that have been +fixed, see the file RELEASE_NOTES (in the root directory of the sendmail +distribution). + +This list is not guaranteed to be complete. + + +* Null bytes are not handled properly in headers. + + Sendmail should handle full binary data. As it stands, it handles + all values in the body, but only 0x01-0x80 and 0xA0-0xFF in + the header. Notably missing is 0x00, which would require a major + restructuring of the code -- for example, almost no C library support + could be used to handle strings. + +* Duplicate error messages. + + Sometimes identical, duplicate error messages can be generated. As + near as I can tell, this is rare and relatively innocuous. + +* $c (hop count) macro improperly set. + + The $c macro is supposed to contain the current hop count, for use + when calling a mailer. This macro is initialized too early, and + is always zero (or the value of the -c command line flag, if any). + This macro will probably be removed entirely in a future release; + I don't believe there are any mailers left that require it. + +* If you EXPN a list or user that has a program mailer, the output of + EXPN will include ``@local.host.name''. You can't actually mail to + this address. It's not clear what the right behaviour is in this + circumstance. + +* MX records that point at non-existent hosts work strangly. + + Consider the DNS records: + + hostH MX 1 hostA + MX 2 hostB + hostA A 128.32.8.9 + + (note that there is no A record for hostB). If hostA is down, + an attempt to send to hostH gives "host unknown" -- that is, it + reflects out the status on the last host it tries, which in this + case is hostB, which is unknown. It probably ought to eliminate + hostB early in processing. + +* \231 considered harmful. + + Header addresses that have the \231 character (and possibly others + in the range \201 - \237) behave in odd and usually unexpected ways. + +* accept() problem on SVR4. + + Apparently, the sendmail daemon loop (doing accept()s on the network) + can get into a wierd state on SVR4; it starts logging ``SYSERR: + getrequests: accept: Protocol Error''. The workaround is to kill + and restart the sendmail daemon. We don't have an SVR4 system at + Berkeley that carries more than token mail load, so I can't validate + this. It is likely to be a glitch in the sockets emulation, since + "Protocol Error" is not possible error code with Berkeley TCP/IP. + + I've also had someone report the message ``sendmail: accept: + SIOCGPGRP failed errno 22'' on an SVR4 system. This message is + not in the sendmail source code, so I assume it is also a bug + in the sockets emulation. (Errno 22 is EINVAL "Invalid Argument" + on all the systems I have available, including Solaris 2.x.) + +* Sending user deletion not done properly in :include: lists. + + If you don't have the "m" (me too) option set, then a person + sending to a list that contains themselves should not get a copy + of the message. However, if that list points to a :include: file + that has one address per line, this will break, and the sender + will always get a copy of their own message, just as though the + "m" option were set. + + You can eliminate this by adding commas at the end of each line + of the :include: file. + +* Excessive mailing list nesting can run out of file descriptors. + + If you have a mailing list that includes lots of other mailing + lists, each of which has a separate owner, you can run out of + file descriptors. Each mailing list with a separate owner uses + one open file descriptor (prior to 8.6.6 it was three open + file descriptors per list). This is particularly egregious if + you have your connection cache set to be large. + +* Connection caching breaks if you pass the port number as an argument. + + If you have a definition such as: + + Mport, P=[IPC], F=kmDFMuX, S=11/31, R=21, + M=2100000, T=DNS/RFC822/SMTP, + A=IPC [127.0.0.1] $h + + (i.e., where $h is the port number instead of the host name) the + connection caching code will break because it won't notice that + two messages addressed to different ports should use different + connections. + +* ESMTP SIZE underestimates the size of a message + + Sendmail makes no allowance for headers that it adds, nor does it + account for the SMTP on-the-wire \r\n expansion.

Instead, get a new version via public +FTP from ftp.CS.Berkeley.EDU, file ucb/4bsd/db.tar.Z. This software +is highly recommended; it gets rid of several stupid limits, it's much +faster, and the interface is nicer to animals and plants. You will +also probably find that you have to add -I/where/you/put/db/include +to the sendmail makefile to get db.h to work properly. + +Be sure you remove ndbm.h and ndbm.o from the db distribution. These +will cause problems with sendmail because sendmail already understands +about NEWDB and NDBM coexisting. + + ++--------------------+ +| HOST NAME SERVICES | ++--------------------+ + +If you are using NIS or /etc/hosts, it is critical that you +list the long (fully qualified) name somewhere (preferably first) in +the /etc/hosts file used to build the NIS database. For example, the +line should read + + 128.32.149.68 mastodon.CS.Berkeley.EDU mastodon + +**** NOT **** + + 128.32.149.68 mastodon + +If you do not include the long name, sendmail will complain loudly +about ``unable to qualify my own domain name (mastodon) -- using +short name'' and conclude that your canonical name is the short +version and use that in messages. The name "mastodon" doesn't mean +much outside of Berkeley, and so this creates incorrect and unreplyable +messages. + + ++-------------+ +| USE WITH MH | ++-------------+ + +This version of sendmail notices and reports certain kinds of SMTP +protocol violations that were ignored by older versions. If you +are running MH you may wish to install the patch in contrib/mh.patch +that will prevent these warning reports. This patch also works +with the old version of sendmail, so it's safe to go ahead and +install it. + + ++----------------+ +| USE WITH IDENT | ++----------------+ + +Sendmail 8 supports the IDENT protocol, as defined by RFC 1413. +No ident server is included with this distribution. I have found +copies available on: + + ftp.lysator.liu.se /pub/ident/servers + romulus.ucs.uoknor.edu /networking/ident/servers + ftp.cyf-kr.edu.pl /agh/uciagh/network/ident + +If you want to run an IDENT server, I suggest getting a copy from +one of those sites. Versions are available for several different +systems, including Apollo, BSD, NeXT, AIX, TOPS20, and VMS. + + ++-----------+ +| MAKEFILES | ++-----------+ + +The Makefiles in this release use the new Berkeley "make" that is +available in BSD Net/2 and 4.4BSD. If you are using this version +of make, you may notice one or two places where the Makefile includes +"../../Makefile.inc". This file is not included with the sendmail +distribution because it's not part of sendmail. However, it is, +in toto: + + # @(#)Makefile.inc 8.1 (Berkeley) 6/6/93 + + BINDIR?= /usr/sbin + +The other directories should all have Makefile.dist files that work +on the old make, albeit without all the niceties included. + +You can also get a new Berkeley make from the Net2 release (available +on many public FTP archives). This version should also interpret old +Makefiles, so you could drop it in as your default make. + +For more details, see src/READ_ME. + + ++---------------------+ +| DIRECTORY STRUCTURE | ++---------------------+ + +The structure of this directory tree is: + +cf Source for Berkeley configuration files. These are + different than what you've seen before. They are a + fairly dramatic rewrite, requiring the new sendmail + (since they use new features). +contrib Some contributed tools to help with sendmail. THESE + ARE NOT SUPPORTED by Berkeley -- contact the original + authors if you have problems. (This directory is not + on the 4.4BSD tape.) +doc Documentation. If you are getting source, read + op.me -- it's long, but worth it. +mail.local The source for the local delivery agent used for 4.4BSD. + THIS IS NOT PART OF SENDMAIL! and may not compile + everywhere, since it depends on some 4.4-isms. Warning: + it does mailbox locking differently than other systems. +mailstats Statistics printing program. It has the pathname of + sendmail.st compiled in, so if you've changed that, + beware. This isn't all that useful. +makemap A program that creates the keyed maps used by the $( ... $) + construct in sendmail. It is primitive but effective. + It takes a very simple input format, so you will probably + expect to preprocess must human-convenient formats + using sed scripts before this program will like them. + But it should be functionally complete. +praliases A program to print the DBM or NEWDB version of the + aliases file. +rmail Source for rmail(8). This is used as a delivery + agent for for UUCP, and could presumably be used by + other non-socket oriented mailers. Older versions of + rmail are probably deficient. RMAIL IS NOT PART OF + SENDMAIL!!! The 4.4BSD source is included for you to + look at or try to port to your system. I know it doesn't + compile on {SunOS, HP-UX, OSF/1, other} (pick one). +smrsh The "sendmail restricted shell", which can be used as + a replacement for /bin/sh in the prog mailer to provide + increased security control. NOT PART OF SENDMAIL! +src Source for the sendmail program itself. +test Some test scripts (currently only for compilation aids). diff --git a/usr.sbin/sendmail/RELEASE_NOTES b/usr.sbin/sendmail/RELEASE_NOTES new file mode 100644 index 000000000000..42931dad88d3 --- /dev/null +++ b/usr.sbin/sendmail/RELEASE_NOTES @@ -0,0 +1,4003 @@ + SENDMAIL RELEASE NOTES + @(#)RELEASE_NOTES 8.7.2.1 (Berkeley) 11/19/95 + + +This listing shows the version of the sendmail binary, the version +of the sendmail configuration files, the date of release, and a +summary of the changes in that release. + +8.7.2/8.7.2 95/11/19 + REALLY fix the backslash escapes in SmtpGreetingMessage, + OperatorChars, and UnixFromLine options.

Suggested + by Kari Hurtta. + If a sequence or switch map lookup entry gets a tempfail but then + continues on to another map type, but the name is not found, + return a temporary failure from the sequence or switch map. + For example, if hosts search ``dns files'' and DNS fails + with a tempfail, the hosts map will go on and search files, + but if it fails the whole thing should be a tempfail, not + a permanent (host unknown) failure, even though that is the + failure in the hosts.files map. This error caused hard + bounces when it should have requeued. + Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo + owned by bar mode 700 and inbox being setuid bar stopped + working properly due to excessive paranoia. Pointed out by + John Hawkinson of Panix. + An SMTP RCPT command referencing a host that gave a nameserver + timeout would return a 451 command (8.6 accepted it and + queued it locally). Revert to the 8.6 behaviour in order + to simplify queue management for clustered systems. Suggested + by Gregory Neil Shapiro of WPI. The same problem could break + MH, which assumes that the SMTP session will succeed (tsk, tsk + -- mail gets lost!); this was pointe dout by Stuart Pook of + Infobiogen. + Fix possible buffer overflow in munchstring(). This was not a security + problem because you couldn't specify any argument to this + without first giving up root privileges, but it is still a + good idea to avoid future problems. Problem noted by John + Hawkinson and Sam Hartman of MIT. + ``452 Out of disk space for temp file'' messages weren't being + printed. Fix from David Perlin of Nanosoft. + Don't advertise the ESMTP DSN extension if the SendMIMEErrors option + is not set, since this is required to get the actual DSNs + created. Problem pointed out by John Gardiner Myers of CMU. + Log permission problems that cause .forward and :include: files to + be untrusted or ignored on log level 12 and higher. Suggestted + by Randy Martin of Clemson University. + Allow user ids in U= clauses of M lines to have hyphens and + underscores. + Fix overcounting of recipients -- only happened when sending to an + alias. Pointed out by Mark Andrews of SGI and Jack Woolley + of Systems and Computer Technology Corporation. + If a message is sent to an address that fails, the error message that + is returned could show some extraneous "success" information + included even if the user did not request success notification, + which was confusing. Pointed out by Allan Johannesen of WPI. + Config files that had no AliasFile definition were defaulting to + using /etc/aliases; this caused problems with nullclient + configurations. Change it back to the 8.6 semantics of + having no local alias file unless it is declared. Problem + noted by Charles Karney of Princeton University. + Fix compile problem if NOTUNIX is defined. Pointed out by Bryan + Costales of ICSI. + Map lookups of class "userdb" maps were always case sensitive; they + should be controlled by the -f flag like other maps. Pointed + out by Bjart Kvarme <bjart.kvarme@usit.uio.no>. + Fix problem that caused some addresses to be passed through ruleset 5 + even when they were tagged as "sticky" by prefixing the + address with an "@". Patch from Thomas Dwyer III of Michigan + Technological University. + When converting a message to Quoted-Printable, prevent any lines with + dots alone on a line by themselves. This is because of the + preponderence of broken mailers that still get this wrong. + Code contributed by Per Hedeland of Ericsson. + Fix F{macro}/file construct -- it previously did nothing. Pointed + out by Bjart Kvarme of USIT/UiO (Norway). + Announce whether a cached connection is SMTP or ESMTP (in -v mode). + Requested by Allan Johannesen. + Delete check for text format of alias files -- it should be legal + to have the database format of the alias files without the + text version. Problem pointed out by Joe Rhett of Navigist, + Inc. + If "Ot" was specified with no value, the TZ variable was not properly + imported from the environment. Pointed out by Frank Crawford + <frank@ansto.gov.au>. + Some architectures core dumped on "program" maps that didn't have + extra arguments. Patch from Booker C. Bense of Stanford + University. + Queue run processes would re-spawn daemons when given a SIGHUP; only + the parent should do this. Fix from Brian Coan of the + Association for Progressive Communications. + If MinQueueAge was set and a message was considered but not run + during a queue run and the Timeout.queuereturn interval was + reached, a "timed out" error message would be returned that + didn't include the failed address (and claimed to be a warning + even though it was fatal). The fix is to not return such + messages until they are actually tried, i.e., in the next + MinQueueAge interval. Problem noted by Rein Tollevik of + SINTEF RUNIT, Oslo. + Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions + that have the hes_getmailhost() routine.

Bug + pointed out by John Hawkinson of MIT. + Fix strange case of an executable called by a program map that + returns a value but also a non-zero exit status; this + would give contradictory results in the higher level; in + particular, the default clause in the map lookup would be + ignored. Change to ignore the value if the program returns + non-zero exit status. From Tom Moore of AT&T GIS. + Shorten parameters passed to syslog() in some contexts to avoid a + bug in many vendors' implementations of that routine. Although + this isn't really a bug in sendmail per se, and my solution + has to assume that syslog() has at least a 1K buffer size + internally (I know some vendors have shortened this + dramatically -- they're on their own), sendmail is a popular + target. Also, limit the size of %s arguments in sprintf. + These both have possible security implications. Solutions + suggested by Casper Dik of Sun's Network Security Group + (Holland), Mark Seiden, and others. + Fix a problem that might cause a non-standard -B (body type) + parameter to be passed to the next server with undefined + results. This could have security implications. + If a filesystem was at > 100% utilization, the freediskspace() + routine incorrectly returned an error rather than zero. + Problem noted by G. Paul Ziemba of Alantec. + Change MX sort order so that local hostnames (those in $=w) always + sort first within a given preference. This forces the bestmx + map to always return the local host first, if it is included + in the list of highest priority MX records. From K. Robert + Elz. + Avoid some possible null pointer dereferences. Fixes from Randy + Martin <WOLF@CLEMSON.EDU> + When sendmail starts up on systems that have no fully qualified + domain name (FQDN) anywhere in the first matching host map + (e.g., /etc/hosts if the hosts service searches "files dns"), + sendmail would sleep to try to find a FQDN, which it really + really needs. This has been changed to fall through to the + next map type if it can't find a FQDN -- i.e., if the hosts + file doesn't have a FQDN, it will try dns even though the + short name was found in /etc/hosts. This is probably a crock, + but many people have hosts files without FQDNs. Remember: + domain names are your friends. + Log a high-priority message if you can't find your FQDN during startup. + Suggested by Simon Barnes of Schlumberger Limited. + When using Hesiod, initialize it early to improve error reporting. + Patch from Don Lewis of Silicon Systems, Inc. + Apparently at least some versions of Linux have a 90 !minute! TCP + connection timeout in the kernel. Add a new "connect" timeout + to limit this time. Defaults to zero (use whatever the + kernel provides). Based on code contributed by J.R.

(note trailing dot) with + ``local configuration error'' in nullclient configuration. + Patch from Gregory Neil Shapiro of WPI. + CONFIG: don't allow an alias file in nullclient configurations -- + since all addresses are relayed, they give errors during + rebuild. Suggested by Per Hedeland of Ericsson. + CONFIG: local mailer on Solaris 2 should always get a -f flag because + otherwise the F=S causes the From_ line to imply that root is + the sender. Problem pointed out by Claude Scarpelli of + Infobiogen (France). + NEW FILES: + cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake) + src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake) + src/Makefiles/Makefile.UXPDS + +8.7/8.7 95/09/16 + Fix a problem that could cause sendmail to run out of file + descriptors due to a trashed data structure after a + vfork.

Problem pointed out + by Roy Mongiovi of Georgia Tech. + Clean up the Subject: line on warning messages and return + receipts so that they don't say "Returned mail:"; this + can be confusing. + Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is + useful enough to make it worthwhile printing on "-d". + Avoid logging alias statistics every time you read the alias + file on systems with no database method compiled in. + If you have a name with a trailing dot, and you try looking it + up using gethostbyname without the dot (for /etc/hosts + compatibility), be sure to turn off RES_DEFNAMES and + RES_DNSRCH to avoid finding the wrong name accidently. + Problem noted by Charles Amos of the University of + Maryland. + Don't do timeouts in collect if you are not running SMTP. + There is nothing that says you can't have a long + running program piped into sendmail (possibly via + /bin/mail, which just execs sendmail). Problem reported + by Don "Truck" Lewis of Silicon Systems. + Try gethostbyname() even if the DNS lookup fails iff option I + is not set. This allows you to have hosts listed in + NIS or /etc/hosts that are not known to DNS. It's normally + a bad idea, but can be useful on firewall machines. This + should really be broken out on a separate flag, I suppose. + Avoid compile warnings against BIND 4.9.3, which uses function + prototypes. From Don Lewis of Silicon Systems. + Avoid possible incorrect diagnosis of DNS-related errors caused + by things like attempts to resolve uucp names using + $[ ... $] -- the fix is to clear h_errno at appropriate + times. From Kyle Jones of UUNET. + SECURITY: avoid denial-of-service attacks possible by destroying + the alias database file by setting resource limits low. + This involves adding two new compile-time options: + HASSETRLIMIT (indicating that setrlimit(2) support is + available) and HASULIMIT (indicating that ulimit(2) support + is available -- the Release 3 form is used). The former + is assumed on BSD-based systems, the latter on System + V-based systems. Attack noted by Phil Brandenberger of + Swarthmore University. + New syntaxes in test (-bt) mode: + ``.Dmvalue'' will define macro "m" to "value". + ``.Ccvalue'' will add "value" to class "c". + ``=Sruleset'' will dump the contents of the indicated + ruleset. + ``=M'' will display the known mailers. + ``-ddebug-spec'' is equivalent to the command-line + -d debug flag. + ``$m'' will print the value of macro $m. + ``$=c'' will print the contents of class $=c. + ``/mx host'' returns the MX records for ``host''. + ``/parse address'' will parse address, returning the value of + crackaddr (essentially, the comment information) + and the parsed address (the same as -bv). + ``/try mailer address'' will rewrite address into the form + it will have when presented to the indicated mailer. + ``/tryflags flags'' will set flags used by parsing. The + flags can be `H' for header or `E' for envelope, + and `S' for sender or `R' for recipient. These + can be combined, so `HR' sets flags for header + recipients. + ``/canon hostname'' will try to canonify hostname and + return the result. + ``/map mapname key'' will look up `key' in the indicated + `mapname' and return the result. + Somewhat better handling of UNIX-domain socket addresses -- it + should show the pathname rather than hex bytes. + Restore ``-ba'' mode -- this reads a file from stdin and parses + the header for envelope sender information and uses + CR-LF as message terminators. It was thought to be + obsolete (used only for Arpanet NCP protocols), but it + turns out that the UK ``Grey Book'' protocols require + that functionality. + Fix a fix in previous release -- if gethostname and gethostbyname + return a name without dots, and if an attempt to canonify + that name fails, wait one minute and try again. This can + result in an extra 60 second delay on startup if your system + hostname (as returned by hostname(1)) has no dot and no names + listed in /etc/hosts or your NIS map have a dot. + Check for proper domain name on HELO and EHLO commands per + RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III + of Michigan Technological University. + Relax chownsafe rules slightly -- old version said that if you + can't tell if _POSIX_CHOWN_RESTRICTED is set (that is, + if fpathconf returned EINVAL or ENOSYS), assume that + chown is not safe. The new version falls back to whether + you are on a BSD system or not. This is important for + SunOS, which apparently always returns one of those + error codes. This impacts whether you can mail to files + or not. + Syntax errors such as unbalanced parentheses in the configuration + file could be omitted if you had "Oem" prior to the + syntax error in the config file. Change to always print + the error message. It was especially wierd because it + would cause a "warning" message to be sent to the Postmaster + for every message sent (but with no transcript). Problem + noted by Gregory Paris of Motorola. + Rewrite collect and putbody to handle full 8-bit data, including + zero bytes.

This is to handle the + ``group name: addr1, addr2, ..., addrN;'' syntax (it will + assume that ``group name:'' is a comment on the first + address and the ``;'' is a comment on the last address). + This requires config file support to get right. It does + understand that :: is NOT this syntax, and can be turned + off completely by setting the ColonOkInAddresses option. + Level 6 config files added with new mailer flags: + A Addresses are aliasable. + i Do udb rewriting on envelope as well as header + sender lines. Applies to the from address mailer + flags rather than the recipient mailer flags. + j Do udb rewriting on header recipient addresses. + Applies to the sender mailer flags rather than the + recipient mailer flags. + k Disable check for loops when doing HELO command. + o Always run as the mail recipient, even on local + delivery. + w Check for an /etc/passwd entry for this user. + 5 Pass addresses through ruleset 5. + : Check for :include: on this address. + | Check for |program on this address. + / Check for /file on this address. + @ Look up sender header addresses in the user + database. Applies to the mailer flags for the + mailer corresponding to the envelope sender + address, rather than to recipient mailer flags. + Pre-level 6 configuration files set A, w, 5, :, |, /, and @ + on the "local" mailer, the o flag on the "prog" and "*file*" + mailers, and the ColonOkInAddresses option. + Eight-to-seven bit MIME conversions. This borrows ideas from + John Beck of Hewlett-Packard, who generously contributed + their implementation to me, which I then didn't use (see + mime.c for an explanation of why). This adds the + EightBitMode option (a.k.a. `8') and an F=8 mailer flag + to control handling of 8-bit data. These have to cope with + two types of 8-bit data: unlabelled 8-bit data (that is, + 8-bit data that is entered without declaring it as 8-bit + MIME -- technically this is illegal according to the + specs) and labelled 8-bit data (that is, it was declared + as 8BITMIME in the ESMTP session or by using the + -B8BITMIME command line flag). If the F=8 mailer flag is + set then 8-bit data is sent to non-8BITMIME machines + instead of converting to 7 bit (essentially using + just-send-8 semantics). The values for EightBitMode are: + m convert unlabelled 8-bit input to 8BITMIME, and do + any necessary conversion of 8BITMIME to 7BIT + (essentially, the full MIME option). + p pass unlabelled 8-bit input, but convert labelled + 8BITMIME input to 7BIT as required (default). + s strict adherence: reject unlabelled 8-bit input, + convert 8BITMIME to 7BIT as required. The F=8 + flag is ignored. + Unlabelled 8-bit data is rejected in mode `s' regardless of + the setting of F=8. + Add new internal class 'n', which is the set of MIME Content-Types + which can not be 8 to 7 bit encoded because of other + considerations. Types "multipart/*" and "message/*" are + never directly encoded (although their components can be). + Add new internal class 's', which is the set of subtypes of the + MIME message/* content type that can be treated as though + they are an RFC822 message. It is predefined to have + "rfc822". Suggested By Kari Hurtta. + Add new internal class 'e'. This is the set of MIME + Content-Transfer-Encodings that can be converted to + a seven bit format (Quoted-Printable or Base64). It is + preinitialized to contain "7bit", "8bit", and "binary". + Add C=charset mailer parameter and the the DefaultCharSet option (no + short name) to set the default character set to use in the + Content-Type: header when doing encoding of an 8-bit message + which isn't marked as MIME into MIME format. If the C= + parameter is set on the Envelope From address, use that as + the default encoding; else use the DefaultCharSet option. + If neither is set, it defaults to "unknown-8bit" as + suggested by RFC 1428 section 3. + Allow ``U=user:group'' field in mailer definition to set a default + user and group that a mailer will be executed as. This + overrides the 'u' and 'g' options, and if the `F=S' flag is + also set, it is the uid/gid that will always be used (that + is, the controlling address is ignored). The values may be + numeric or symbolic; if only a symbolic user is given (no + group) that user's default group in the passwd file is used + as the group. Based on code donated by Chip Rosenthal of + Unicom. + Allow `u' option to also accept user:group as a value, in the same + fashion as the U= mailer option. + Add the symbolic time zone name in the Arpanet format dates (as + a comment). This adds a new compile-time configuration + flag: TZ_TYPE can be set to TZ_TM_NAME (use the value + of (struct tm *)->tm_name), TZ_TM_ZONE (use the value + of (struct tm *)->tm_zone), TZ_TZNAME (use extern char + *tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use + timezone()), or TZ_NONE (don't include the comment). Code + from Chip Rosenthal. + The "Timeout" option (formerly "r") is extended to allow suboptions. + For example, + O Timeout.helo = 2m + There are also two new suboptions "queuereturn" and + "queuewarn"; these subsume the old T option. Thus, to + set them both the preferred new syntax is + O Timeout.queuereturn = 5d + O Timeout.queuewarn = 4h + Sort queue by host name instead of by message priority if the + QueueSortOrder option (no short name) is set is set to + ``host''. This makes better use of the connection cache, + but may delay more ``interactive'' messages behind large + backlogs under some circumstances. This is probably a + good option if you have high speed links or don't do lots + of ``batch'' messages, but less good if you are using + something like PPP on a 14.4 modem. Based on code + contributed by Roy Mongiovi of Georgia Tech (my main + contribution was to make it configurable). + Save i-number of df file in qf file to simplify rebuilding of queue + after disasterous disk crash. Suggested by Kyle Jones of + UUNET; closely based on code from KJS DECWRL code written + by Paul Vixie. NOTA BENE: The qf files produced by 8.7 + are NOT back compatible with 8.6 -- that is, you can convert + from 8.6 to 8.7, but not the other direction. + Add ``F=d'' mailer flag to disable all use of angle brackets in + route-addrs in envelopes; this is because in some cases + they can be sent to the shell, which interprets them as + I/O redirection. + Don't include error file (option E) with return-receipts; this + can be confusing. + Don't send "Warning: cannot send" messages to owner-* or + *-request addresses. Suggested by Christophe Wolfhugel + of the Institut Pasteur, Paris. + Allow -O command line flag to set long form options. + Add "MinQueueAge" option to set the minimum time between attempts + to run the queue. For example, if the queue interval + (-q value) is five minutes, but the minimum queue age + is fifteen minutes, jobs won't be tried more often than + once every fifteen minutes. This can be used to give + you more responsiveness if your delivery mode is set to + queue-only. + Allow "fileopen" timeout (default: 60 seconds) for opening + :include: and .forward files. + Add "-k", "-v", and "-z" flags to map definitions; these set the + key field name, the value field name, and the field + delimiter. The field delimiter can be a single character + or the sequence "\t" or "\n" for tab or newline. + These are for use by NIS+ and similar access methods. + Change maps to always strip quotes before lookups; the -q flag + turns off this behaviour. Suggested by Motonori Nakamura. + Add "nisplus" map class. Takes -k and -v flags to choose the + key and value field names respectively. Code donated by + Sun Microsystems. + Add "hesiod" map class. The "file name" is used as the + "HesiodNameType" parameter to hes_resolve(3). Returns the + first value found for the match. Code donated by Scott + Hutton of Indiana University. + Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to + specify the name of the property that is searched as the + key and a -v flag to specify the name of the property that + is returned as the value (defaults to "members"). The + default map is "/aliases". Some code based on code + contributed by Robert La Ferla of Hot Software. + Add "text" map class. This does slow, linear searches through + text files. The -z flag specifies a column delimiter + (defaults to any sequence of white space), the -k flag + sets the key column number, and the -v flag sets the + value column number. Lines beginning with `#' are treated + as comments. + Add "program" map class to execute arbitrary programs. The search + key is presented as the last argument; the output is one + line read from the programs standard output. Exit statuses + are from sysexits.h. + Add "sequence" map class -- searches maps in sequence until it + finds a match. For example, the declarations: + Kmap1 ... + Kmap2 ... + Kmapseq sequence map1 map2 + defines a map "mapseq" that first searches map1; if the + value is found it is returned immediately, otherwise + map2 is searched and the value returned. + Add "switch" map class. This is much like "sequence" except that + the ordering is fetched from an external file, usually + the system service switch. The parameter is the name of + the service to switch on, and the maps that it will use + are the name of the switch map followed by ".service_type". + For example, if the declaration of the map is + Ksample switch hosts + and the system service switch specifies that hosts are + looked up using dns and nis in that order, then this is + equivalent to + Ksample sequence sample.dns sample.nis + The subordinate maps (sample.*) must already be defined. + Add "user" map class -- looks up users using getpwnam. Takes a + "-v field" flag on the definition that tells what passwd + entry to return -- legal values are name, passwd, uid, gid, + gecos, dir, and shell. Generally expected to be used with + the -m (matchonly) flag. + Add "bestmx" map class -- returns the best MX value for the host + listed as the value. If there are several "best" MX records + for this host, one will be chosen at random. + Add "userdb" map class -- looks up entries in the user database. + The "file name" is actually the tag that will be used, + typically "mailname". If there are multiple entries + matching the name, the one chosen is undefined. + Add multiple queue timeouts (both return and warning). These are + set by the Precedence: or Priority: header fields to one of + three values. If a Priority: is set and has value "normal", + "urgent", or "non-urgent" the corresponding timeouts are + used. If no priority is set, the Precedence: is consulted; + if negative, non-urgent timeouts are used; if greater than + zero, urgent timeouts are used. Otherwise, normal timeouts + are used. The timeouts are set by setting the six timeouts + queue{warn,return}.{urgent,normal,non-urgent}. + Fix problem when a mail address is resolved to a $#error mailer + with a temporary failure indication; it works in SMTP, + but when delivering locally the mail is silently discarded. + This patch, from Kyle Jones of UUNET, bounces it instead + of queueing it (queueing is very hard). + When using /etc/hosts or NIS-style lookups, don't assume that + the first name in the list is the best one -- instead, + search for the first one with a dot. For example, if + an /etc/hosts entry reads + 128.32.149.68 mammoth mammoth.CS.Berkeley.EDU + this change will use the second name as the canonical + machine name instead of the initial, unqualified name. + Change dequote map to replace spaces in quoted text with a value + indicated by the -s flag on the dequote map definition. + For example, ``Mdequote dequote -s_'' will change + "Foo Bar" into an unquoted Foo_Bar instead of leaving it + quoted (because of the space character). Suggested by Dan + Oscarsson for use in X.400 addresses. + Implement long macro names as ${name}; long class names can + be similarly referenced as $={name} and $~{name}. + Definitions are (e.g.) ``D{name}value''. Names that have + a leading lower case letter or punctuation characters are + reserved for internal use by sendmail; i.e., config files + should use names that begin with a capital letter. Based + on code contributed by Dan Oscarsson. + Fix core dump if getgrgid returns a null group list (as opposed + to an empty group list, that is, a pointer to a list + with no members). Fix from Andrew Chang of Sun Microsystems. + Fix possible core dump if malloc fails -- if the malloc in xalloc + failed, it called syserr which called newstr which called + xalloc.... The newstr is now avoided for "panic" messages. + Reported by Stuart Kemp of James Cook University. + Improve connection cache timeouts; previously, they were not even + checked if you were delivering to anything other than an + IPC-connected host, so a series of (say) local mail + deliveries could cause cached connections to be open + much longer than the specified timeout. + If an incoming message exceeds the maximum message size, stop + writing the incoming bytes to the queue data file, since + this can fill your mqueue partition -- this is a possible + denial-of-service attack. + Don't reject all numeric local user names unless HESIOD is + defined. It turns out that Posix allows all-numeric + user names. Fix from Tony Sanders of BSDI. + Add service switch support. If the local OS has a service + switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf + on DEC systems) that will be used; otherwise, it falls back + to using a local mechanism based on the ServiceSwitchFile + option (default: /etc/service.switch). For example, if the + service switch lists "files" and "nis" for the aliases + service, that will be the default lookup order. the "files" + ("local" on DEC) service type expands to any alias files + you listed in the configuration file, even if they aren't + actually file lookups. + Option I (NameServerOptions) no longer sets the "UseNameServer" + variable which tells whether or not DNS should be considered + canonical. This is now determined based on whether or not + "dns" is in the service list for "hosts". + Add preliminary support for the ESMTP "DSN" extension (Delivery + Status Notifications). DSN notifications override + Return-Receipt-To: headers, which are bogus anyhow. + Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer + definitions to define the types used in DSN returns for + MTA names, addresses, and diagnostics respectively. + Extend heuristic to force running in ESMTP mode to look for the + five-character string "ESMTP" anywhere in the 220 greeting + message (not just the second line). This is to provide + better compatibility with other ESMTP servers. + Print sequence number of job when running the queue so you can + easily see how much progress you have made. Suggested + by Peter Wemm of DIALix. + Map newlines to spaces in logged message-ids; some versions of + syslog truncate the rest of the line after newlines. + Suggested by Fletcher Mattox of U. Texas. + Move up forking for job runs so that if a message is split into + multiple envelopes you don't get "fork storms" -- this + also improves the connection cache utilization. + Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for + the purposes of refusing to send error returns. Suggested + by Motonori Nakamura of Ritsumeikan University. + Relax rules on when a file can be written when referenced from + the aliases file: use the default uid/gid instead of the + real uid/gid. This allows you to create a file owned by + and writable only by the default uid/gid that will work + all the time (without having the setuid bit set). Change + suggested by Shau-Ping Lo and Andrew Cheng of Sun + Microsystems. + Add "DialDelay" option (no short name) to provide an "extra" + delay for dial on demand systems. If this is non-zero + and a connect fails, sendmail will wait this long and + then try again. If it takes longer than the kernel + timeout interval to establish the connection, this + option can give the network software time to establish + the link. The default units are seconds. + Move logging of sender information to be as early as possible; + previously, it could be delayed a while for SMTP mail + sent to aliases. Suggested by Brad Knowles of the + Defense Information Systems Agency. + Call res_init() before setting RES_DEBUG; this is required by + BIND 4.9.3, or so I'm told. From Douglas Anderson of + the National Computer Security Center. + Add xdelay= field in logs -- this is a transaction delay, telling + you how long it took to deliver to this address on the + last try. It is intended to be used for sorting mailing + lists to favor "quick" addresses. Provided for use by + the mailprio scripts (see below). + If a map cannot be opened, and that map is non-optional, and + an address requires that map for resolution, queue the + map instead of bouncing it. This involves creating a + pseudo-class of maps called "bogus-map" -- if a required + map cannot be opened, the class is changed to bogus-map; + all queries against bogus-map return "tempfail". The + bogus-map class is not directly accessible. A sample + implementation was donated by Jem Taylor of Glasgow + University Computing Service. + Fix a possible core dump when mailing to a program that talks + SMTP on its standard input. Fix from Keith Moore of + the University of Kentucky. + Make it possible to resolve filenames to $#local $: @ /filename; + previously, the "@" would cause it to not be recognized + as a file. Problem noted by Brian Hill of U.C. Davis. + Accept a -1 signal to re-exec the daemon. This only works if + argv[0] is a full path to sendmail. + Fix bug in "addr=..." field in O option on little-endian machines + -- the network number wasn't being converted to network + byte order. Patch from Kurt Lidl of Pix Technologies + Corporation. + Pre-initialize the resolver early on; this is to avoid a bug with + BIND 4.9.3 that can cause the _res.retry field to get + reset to zero, causing all name server lookups to time + out. Fix from Matt Day of Artisoft. + Restore T line (trusted users) in config file -- but instead of + locking out the -f flag, they just tell whether or not + an X-Authentication-Warning: will be added. This really + just creates new entries in class 't', so "Ft/file/name" + can be used to read trusted user names from a file. + Trusted users are also allowed to execute programs even + if they have a shell that isn't in /etc/shells. + Improve NEWDB alias file rebuilding so it will create them + properly if they do not already exist. This had been + a MAYBENEXTRELEASE feature in 8.6.9. + Check for @:@ entry in NIS maps before starting up to avoid + (but not prevent, sigh) race conditions. This ought to + be handled properly in ypserv, but isn't. Suggested by + Michael Beirne of Motorola. + Refuse connections if there isn't enough space on the filesystem + holding the queue. Contributed by Robert Dana of Wolf + Communications. + Skip checking for directory permissions in the path to a file + when checking for file permissions iff setreuid() + succeeded -- it is unnecessary in that case. This avoids + significant performance problems when looking for .forward + files. Based on a suggestion by Win Bent of USC. + Allow symbolic ruleset names. Syntax can be "Sname" to get an + arbitrary ruleset number assigned or "Sname = integer" + to assign a specific ruleset number. Reference is + $>name_or_number. Names can be composed of alphas, digits, + underscore, or hyphen (first character must be non-numeric). + Allow -o flag on AliasFile lines to make the alias file optional. + From Bryan Costales of ICSI. + Add NoRecipientAction option to handle the case where there is + no legal recipient header in the message. It can take + on values: + None Leave the message as is. The + message will be passed on even + though it is in technically + illegal syntax. + Add-To Add a To: header with any + recipients that it can find from + the envelope. This risks exposing + Bcc: recipients. + Add-Apparently-To Add an Apparently-To: header. This + has almost no redeeming social value, + and is provided only for back + compatibility. + Add-To-Undisclosed Add a header reading + To: undisclosed-recipients:; + which will have the effect of + making the message legal without + exposing Bcc: recipients. + Add-Bcc To add an empty Bcc: header. + There is a chance that mailers down + the line will delete this header, + which could cause exposure of Bcc: + recipients. + The default is NoRecipientAction=None. + Truncate (rather than delete) Bcc: lines in the header. This + should prevent later sendmails (at least, those that don't + themselves delete Bcc:) from considering this message to + be non-conforming -- although it does imply that non-blind + recipients can see that a Bcc: was sent, albeit not to whom. + Add SafeFileEnvironment option. If declared, files named as delivery + targets must be regular files in addition to the regular + checks. Also, if the option is non-null then it is used as + the name of a directory that is used as a chroot(2) + environment for the delivery; the file names listed in an + alias or forward should include the name of this root. + For example, if you run with + O SafeFileEnvironment=/arch + then aliases should reference "/arch/rest/of/path". If a + value is given, sendmail also won't try to save to + /usr/tmp/dead.letter (instead it just leaves the job in the + queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit. + Support -A flag for alias files; this will comma concatenate like + entries. For example, given the aliases: + list: member1 + list: member2 + and an alias file declared as: + OAhash:-A /etc/aliases + the final alias inserted will be "list: member1,member2"; + without -A you will get an error on the second and subsequent + alias for "list". Contributed by Bryan Costales of ICSI. + Line-buffer transcript file. Suggested by Liudvikas Bukys. + Fix a problem that could cause very long addresses to core dump in + some special circumstances.

This didn't really give + any extra security and caused some people some problems. + (If you -really- want this, define PICKY_QF_NAME_CHECK + at compile time.) Suggested by Kyle Jones of UUNET. + (Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and + merge with DSN code; this is simpler and more consistent. + This may affect some people who have written their own + checkcompat() routine. + (Internal change.) Eliminate `D' line in qf file. The df file + is now assumed to be the same name as the qf file (with + the `q' changed to a `d', of course). + Avoid forking for delivery if all recipient mailers are marked as + "expensive" -- this can be a major cost on some systems. + Essentially, this forces sendmail into "queue only" mode + if all it is going to do is queue anyway. + Avoid sending a null message in some rather unusual circumstances + (specifically, the RCPT command returns a temporary + failure but the connection is lost before the DATA + command). Fix from Scott Hammond of Secure Computing + Corporation. + Change makesendmail to use a somewhat more rational naming scheme: + Makefiles and obj directories are named $os.$rel.$arch, + where $os is the operating system (e.g., SunOS), $rel is + the release number (e.g., 5.3), and $arch is the machine + architecture (e.g., sun4). Any of these can be omitted, + and anything after the first dot in a release number can + be replaced with "x" (e.g., SunOS.4.x.sun4). The previous + version used $os.$arch.$rel and was rather less general. + Change makesendmail to do a "make depend" in the target directory + when it is being created. This involves adding an empty + "depend:" entry in most Makefiles. + Ignore IDENT return value if the OSTYPE field returns "OTHER", + as indicated by RFC 1413. Pointed out by Kari Hurtta + of the Finnish Meteorological Institute. + Fix problem that could cause multiple responses to DATA command + on header syntax errors (e.g., lines beginning with colons). + Problem noted by Jens Thomassen of the University of Oslo. + Don't let null bytes in headers cause truncation of the rest of + the header. + Log Authentication-Warning:s. Suggested by Motonori Nakamura. + Increase timeouts on message data puts to allow time for receivers + to canonify addresses in headers on the fly. This is still + a rather ugly heuristic. From Motonori Nakamura. + Add "HasWildcardMX" suboption to ResolverOptions; if set, MX + records are not used when canonifying names, and when MX + lookups are done for addressing they must be fully + qualified. This is useful if you have a wildcard MX record, + although it may cause other problems. In general, don't use + wildcard MX records. Patch from Motonori Nakamura. + Eliminate default two-line SMTP greeting message. Instead of + adding an extra "ESMTP spoken here" line, the word "ESMTP" + is added between the first and second word of the first + line of the greeting message (i.e., immediately after the + host name). This eliminates the need for the BROKEN_SMTP_PEERS + compile flag. Old sendmails won't see the ESMTP, but that's + acceptable because SIZE was the only useful extension that + old sendmails understand. + Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1 + invoked state dumps. From Masaharu Onishi. + Allow on-line comments in .forward and :include: files; they are + introduced by the string "<LWSP>#@#<LWSP>", where <LWSP> + is a space or a tab. This is intended for native + representation of non-ASCII sets such as Japanese, where + existing encodings would be unreadable or would lose + data -- for example, + <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori + (romanized/less information) + <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?= + =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?= + (with MIME encoding, not human readable) + <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B + (native encoding with ISO-2022-JP) + The last form is human readable in the Japanese environment. + Based on a fix from (surprise!) Motonori Nakamura. + Don't make SMTP error returns on MAIL FROM: line be "sticky" for all + messages to that host; these are most frequently associated + with addresses rather than the host, with the exception of + 421 (service shutting down). The effect was to cause queues + to sometimes take an excessive time to flush. Reported by + Robert Sargent of Southern Geographics Technologies and + Eric Prestemon of American University. + Add Nice=N mailer option to set the niceness at which a mailer will + run. This is actually a relative niceness (that is, an + increment on the background value). + Log queue runs that are skipped due to high loads. They are logged + at LOG_INFO priority iff the log level is > 8. Contributed + by Bruce Nagel of Data General. + Allow the error mailer to accept a DSN-style error status code + instead of an sysexits status code in the host part. + Anything with a dot will be interpreted as a DSN-style code. + Add new mailer flag: F=3 will tell translations to Quoted-Printable + to encode characters that might be munged by an EBCDIC system + in addition to the set required by RFC 1521. The additional + characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~. + (Think of "IBM 360" as the mnemonic for this flag.) + Change check for mailing to files to look for a pathname of [FILE] + rather than looking for the mailer named *file*. The mapping + of leading slashes still goes to the *file* mailer. This + allows you to implement the *file* mailer as a separate + program, for example, to insert a Content-Length: header + or do special security policy. However, note that the usual + initial checking for the file permissions is still done, and + the program in question needs to be very careful about how + it does the file write to avoid security problems. + Be able to read ~root/.forward even if the path isn't accessible to + regular users. This is disrecommended because sendmail + sometimes does not run as root (e.g., when an unsafe option + is specified on the command line), but should otherwise be + safe because .forward files must be owned by the user for + whom mail is being forwarded, and cannot be a symbolic link. + Suggested by Forrest Aldrich of Wang Laboratories. + Add new "HostsFile" option that is the pathname to the /etc/hosts + file. This is used for canonifying hostnames when the + service type is "files". + Implement programs on F (read class from file) line. The syntax is + Fc|/path/to/program to read the output from the program + into class "c". + Probe the network interfaces to find alternate names for this + host. Requires the SIOCGIFCONF ioctl call. Code + contributed by SunSoft. + Add "E" configuration line to set or propogate environment + variables into children. "E<envar>" will propogate + the named variable from the environment when sendmail + was invoked into any children it calls; "E<envar>=<value>" + sets the named variable to the indicated value. Any + variables not explicitly named will not be in the child + environment. However, sendmail still forces an + "AGENT=sendmail" environment variable, in part to enforce + at least one environment variable, since many programs and + libraries die horribly if this is not guaranteed. + Change heuristic for rebuilding both NEWDB and NDBM versions of + alias databases -- new algorithm looks for the substring + "/yp/" in the file name. This is more portable and involves + less overhead. Suggested by Motonori Nakamura. + Dynamically allocate the queue work list so that you don't lose + jobs in large queue runs. The old QUEUESIZE compile parameter + is replaced by QUEUESEGSIZE (the unit of allocation, which + should not need to be changed) and the MaxQueueRunSize option, + which is the absolute maximum number of jobs that will ever + be handled in a single queue run. Based on code contributed + by Brian Coan of the Institute for Global Communications. + Log message when a message is dropped because it exceeds the maximum + message size. Suggested by Leo Bicknell of Virginia Tech. + Allow trusted users (those on a T line or in $=t) to use -bs without + an X-Authentication-Warning: added. Suggested by Mark Thomas + of Mark G. Thomas Consulting. + Announce state of compile flags on -d0.1 (-d0.10 throws in the + OS-dependent defines). The old semantic of -d0.1 to not + run the daemon in background has been moved to -d99.100, + and the old 52.5 flag (to avoid disconnect() from closing + all output files) has been moved to 52.100. This makes + things more consistent (flags below .100 don't change + semantics) and separates out the backgrounding so that + it doesn't happen automatically on other unrelated debugging + flags. + If -t is used but no addresses are found in the header, give an + error message rather than just doing nothing. Fix from + Motonori Nakamura. + On systems (like SunOS) where the effective gid is not necessarily + included in the group list returned by getgroups(), the + `restrictmailq' option could sometimes cause an authorized + user to not be able to use `mailq'. Fix from Charles Hannum + of MIT. + Allow symbolic service names for [IPC] mailers. Suggested by + Gerry Magennis of Logica International. + Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs + when running DNS. For example, if the name FTP.Foo.ORG is + a CNAME for Cruft.Foo.ORG, then when sitting on a machine in + the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG" + if this option is not set, or "FTP.Foo.ORG" if it is set. + This is technically illegal under RFC 822 and 1123, but the + IETF is moving toward legalizing it. Note that turning on + this option is not sufficient to guarantee that a downstream + neighbor won't rewrite the address for you. + Add "-m" flag to makesendmail script -- this tells you what object + directory and Makefile it will use, but doesn't actually do + the make. + Do some additional checking on the contents of the qf file to try + to detect attacks against the qf file. In particular, + abort on any line beginning "From ", and add an "end of + file" line -- any data after that line is prohibited. + Always use /etc/sendmail.cf, regardless of the arbitrary vendor + choices. This can be overridden in the Makefile by using + either -DUSE_VENDOR_CF_PATH to get the vendor location + (to the extent that we know it) or by defining + _PATH_SENDMAILCF (which is a "hard override"). This allows + sendmail 8 to have more consistent installation instructions. + Allow macros on `K' line in config file. Suggested by Andrew Chang + of Sun Microsystems. + Improved symbol table hash function from Eric Wassenaar. This one + is at least 50% faster. + Fix problem that didn't notice that timeout on file open was a + transient error. Fix from Larry Parmelee of Cornell + University. + Allow comments (lines beginning with a `#') in files read for + classes. Suggested by Motonori Nakamura. + Make SIGINT (usually ^C) in test mode return to the prompt instead + of dropping out entirely. This makes testing some of the + name server lookups easier to deal with when there are + hung servers. From Motonori Nakamura. + Add new ${opMode} macro that is set to the current operation mode + (e.g., `s' for -bs, `t' for -bt, etc.). Suggested by + Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>. + Add new delivery mode (Odd) that defers all map lookups to queue runs. + Kind of like queue-only mode (Odq) except it tries to avoid + any external service requests; for dial-on-demand hosts that + want to minimize DNS lookups when mail is being queued. For + this to work you will also have to make sure that gethostbyname + of your local host name does not do a DNS lookup. + Improved handling of "out of space" conditions from John Myers of + Carnegie Mellon. + Improved security for mailing to files on systems that have fchmod(2) + support. + Improve "cannot send message for N days" message -- now says "could + not send for past N days". Suggested by Tom Moore of AT&T + Global Information Solutions. + Less misleading Subject: line on messages sent to postmaster only. + From Motonori Nakamura. + Avoid duplicate error messages on bad command line flags. From + Motonori Nakamura. + Better error message for case where ruleset 0 falls off the end + or otherwise does not resolve to a canonical triple. + Fix a problem that could cause multiple bounce messages if a bad + address was sent along with a good address to an SMTP + site where that SMTP site returned a 4yz code in response + to the final dot of the data. Problem reported by David + James of British Telecom. + Add "volatile" declarations so that gcc -O2 will work. Patches + from Alexander Dupuy of System Management ARTS. + Delete duplicates in MX lists -- believe it or not, there are sites + that list the same host twice in an MX list. This deletion + only works on adjacent preferences, so an MX list that + had A=5, B=10, A=15 would leave both As, but one that had + A=5, A=10, B=15 would reduce to A, B. This is intentional, + just in case there is something wierd I haven't thought of. + Suggested by Barry Shein of Software Tool & Die. + SECURITY: .forward files cannot be symbolic links.

The semantics of this are undefined + for regular maps, but it can be useful for the user database. + MAKEMAP: lock database file while rebuilding to avoid sendmail + lookups while the rebuild is going on. There is a race + condition between the open(... O_TRUNC ...) and the lock + on the file, but it should be quite small. + SMRSH: sendmail restricted shell added to the release. This can + be used as an alternative to /bin/sh for the "prog" mailer, + giving the local administrator more control over what + programs can be run from sendmail. + MAIL.LOCAL: add this local mailer to the tape. It is not really + part of the release proper, and isn't fully supported; in + particular, it does not run on System V based systems and + never will. + CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon + to allow rmail to compile on systems that don't have + function prototypes and systems that don't have snprintf. + CONTRIB: add the "mailprio" scripts that will help you sort mailing + lists by transaction delay times so that addresses that + respond quickly get sent first. This is to prevent very + sluggish servers from delaying other peoples' mail. + Contributed by Tony Sanders of BSDI. + CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders + of BSDI. This has a lot of comments to help people out. + CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead, + put this on the m4 command line.

Problem noted by John Gardiner Myers of CMU. + CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration. + From Paul Riddle of the University of Maryland, Baltimore + County. + CONFIG: Catch and reject "." as a host address. + CONFIG: Generalize domaintable to look up all domains, not + just unqualified ones. + CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it + was never used and didn't work anyway. + CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer + and d on all mailers in the UUCP class. + CONFIG: Allow "user+detail" to be aliased specially: it will first + look for an alias for "user+detail", then for "user+*", and + finally for "user". This is intended for forwarding mail + for system aliases such as root and postmaster to a + centralized hub. + CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above). + CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set. + The F=8 flag is also set on the "relay" mailer, since + this is expected to be another sendmail. + CONFIG: avoid qualifying all UUCP addresses sent via SMTP with + the name of the UUCP_RELAY -- in some cases, this is the + wrong value (e.g., when we have local UUCP connections), + and this can create unreplyable addresses. From Chip + Rosenthal of Unicom. + CONFIG: add confRECEIVED_HEADER to change the format of the + Received: header inserted into all messages. Suggested by + Gary Mills of the University of Manitoba. + CONFIG: Make "notsticky" the default; use FEATURE(stickyhost) + to get the old behaviour. I did this upon observing + that almost everyone needed this feature, and that the + concept I was trying to make happen didn't work with + some user agents anyway. FEATURE(notsticky) still works, + but it is a no-op. + CONFIG: Add LUSER_RELAY -- the host to which unrecognized user + names are sent, rather than immediately diagnosing them + as User Unknown. + CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS, + and RELAY_MAILER_ARGS to set the arguments for the + indicated mailers. All default to "IPC $h". Patch from + Larry Parmelee of Cornell University. + CONFIG: pop mailer needs F=n flag to avoid "annoying side effects + on the client side" and F=P to get an appropriate + return-path. From Kimmo Suominen. + CONFIG: add FEATURE(local_procmail) to use the procmail program + as the local mailer. For addresses of the form "user+detail" + the "detail" part is passed to procmail via the -a flag. + Contributed by Kimmo Suominen. + CONFIG: add MAILER(procmail) to add an interface to procmail for + use from mailertables.

Contributed by Kimmo Suominen. + CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers. + CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From + Paul Southworth of CICNet Systems Support. + CONFIG: use -a$g as default to UUCP mailers, instead of -a$f. + This causes the null return path to be rewritten as + MAILER-DAEMON; otherwise UUCP gets horribly confused. + From Michael Hohmuth of Technische Universitat Dresden. + CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that + list us as the best possible MX record to be treated as + though they were local (essentially, assume that they + are included in $=w). This can cause additional DNS + traffic, but is easier to administer if this fits your + local model. It does not work reliably if there are + multiple hosts that share the best MX preference. + Code contributed by John Oleynick of Rutgers. + CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted + SHell) instead of /bin/sh as the program used for delivery + to programs. If an argument is included, it is used as + the path to smrsh; otherwise, /usr/local/etc/smrsh is + assumed. + CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the + size of messages to the local and procmail mailers + respectively. Contributed by Brad Knowles of the Defense + Information Systems Agency. + CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments + (just like text outside of angle brackets) in order to + properly deal with ``group: addr1, ... addrN;'' syntax. + CONFIG: Require OSTYPE macro (the defaults really don't apply to + any real systems any more) and tweak the DOMAIN macro + so that it is less likely that users will accidently use + the Berkeley defaults. Also, create some generic files + that really can be used in the real world. + CONFIG: Add new configuration macros to set character sets for + messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET, + SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET. + CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency. + The old name will still be accepted for a while at least. + CONFIG: Implement DECNET_RELAY as spec for host to which DECNET + mail (.DECNET pseudo-domain or node::user) will be sent. + As with all relays, it can be ``mailer:hostname''. Suggested + by Scott Hutton. + CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed + by Barb Dijker of Labyrinth Computer Services. + CONFIG: change confCHECK_ALIASES to default to False -- it has poor + performance for large alias files, and this confused many + people. + CONFIG: Add confCF_VERSION to append local information to the + configuration version number displayed during SMTP startup. + CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it + would only work when locally addressed. Fix from + Edvard Tuinder of Cistron Internet Services. + CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option + "n" (CheckAlaises) is set when rebuilding alias database. + Based on code contributed by Claude Marinier. + CONFIG: Allow mailertable to have values of the form + ``error:code message''. The ``code'' is a status code + derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE. + Contributed by David James <dwj@agw.bt.co.uk>. + CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of + sender domains that will be replaced with the masquerade name. + These domains will not be treated as local, but if mail passes + through with sender addresses in those domains they will be + replaced by the masquerade name. These can also be specified + in a file using MASQUERADE_DOMAIN_FILE(filename). + CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope + as well as the header.

Fix from several + people, including Allan Johannesen, Shane Castle of the + Boulder County Information Services, and Jeff Smith of + Warwick University (all arrived within a few hours of + each other!). + Fix a problem that could cause large jobs to run out of + file descriptors on systems that use vfork() rather + than fork(). + +8.6.11/8.6.11 95/03/08 + The ``possible attack'' message would be logged more often + than necessary if you are using Pine as a user agent. + The wrong host would be reported in the ``possible attack'' + message when attempted from IDENT. + In some cases the syslog buffer could be overflowed when + reporting the ``possible attack'' message. This can + cause denial of service attacks. Truncate the message + to 80 characters to prevent this problem. + When reading the IDENT response a loop is needed around the + read from the network to ensure that you don't get + partial lines. + Password entries without any shell listed (that is, a null + shell) wouldn't match as "ok". Problem noted by + Rob McMahon. + When running BIND 4.9.x a problem could occur because the + _res.options field is initialized differently than it + was historically -- this requires that sendmail call + res_init before it tweaks any bits. + Fix an incompatibility in openxscript() between the file open mode + and the stdio mode passed to fdopen. This caused UnixWare + 2.0 to have conniptions. Fix from Martin Sohnius of + Novell Labs Europe. + Fix problem with static linking of local getopt routine when + using GNU's ld command.

From Fletcher Mattox of the + University of Texas. + Fix a problem that would silently drop "too many hops" error + messages if and only if you were sending to an alias. + From Jon Giltner of the University of Colorado and + Dan Harton of Oak Ridge National Laboratory. + Fix a bug that caused core dumps on some systems if -d11.2 was + set and e->e_message was null. Fix from Bruce Nagel of + Data General. + Fix problem that can still cause df files to be left around + after "hop count exceeded" messages. Fix from Andrew + Chang and Shau-Ping Lo of SunSoft. + Fix a problem that can cause buffer overflows on very long + user names (as might occur if you piped to a program + with a lot of arguments). + Avoid returning an error and re-queueing if the host signature + is null; this can occur on addresses like ``user@.''. + Problem noted by Wesley Craig and the University of + Michigan. + Avoid possible calls to malloc(0) if MCI caching is turned + off. Bug fix from Pierre David of the Laboratoire + Parallelisme, Reseaux, Systemes et Modelisation (PRiSM), + Universite de Versailles - St Quentin, and Jacky + Thibault. + Make a local copy of the line being sent via senttolist() -- in + some cases, buffers could get trashed by map lookups + causing it to do unexpected things. This also simplifies + some of the map code. + CONFIG: No changes (version number only, to keep it in sync + with the binaries). + +8.6.9/8.6.9 94/04/19 + Do all mail delivery completely disconnected from any terminal. + This provides consistency with daemon delivery and + may have some security implications. + Make sure that malloc doesn't get called with zero size, + since that fails on some systems. Reported by Ed + Hill of the University of Iowa. + Fix multi-line values for $e (SMTP greeting message). Reported + by Mike O'Connor of Ford Motor Company. + Avoid syserr if no NIS domain name is defined, but the map it + is trying to open is optional. From Win Bent of USC. + Changes for picky compilers from Ed Gould of Digital Equipment. + Hesiod support for UDB from Todd Miller of the University of + Colorado. Use "hesiod" as the service name in the U + option. + Fix a problem that failed to set the "authentic" host name (that + is, the one derived from the socket info) if you called + sendmail -bs from inetd. Based on code contributed by + Todd Miller (this problem was also reported by Guy Helmer + of Dakota State University). This also fixes a related + problem reported by Liudvikas Bukys of the University of + Rochester. + Parameterize "nroff -h" in all the Makefiles so people with + variant versions can use them easily. Suggested by + Peter Collinson of Hillside Systems. + SMTP "MAIL" commands with multiple ESMTP parameters required two + spaces between parameters instead of one. Reported by + Valdis Kletnieks of Virginia Tech. + Reduce the number of system calls during message collection by + using global timeouts around the collect() loop. This + code was contributed by Eric Wassenaar. + If the initial hostname name gathering results in a name + without a dot (usually caused by NIS misconfiguration) + and BIND is compiled in, directly access DNS to get + the canonical name. This should make life easier for + Solaris systems. If it still can't be resolved, and + if the name server is listed as "required", try again + in 30 seconds. If that also fails, exit immediately to + avoid bogus "config error: mail loops back to myself" + messages. + Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error + message to explain how much space was available and + sound a bit less threatening. Suggested by Stan Janet + of the National Institute of Standards and Technology. + If mail is delivered to an alias that has an owner, deliver any + requested return-receipt immediately, and strip the + Return-Receipt-To: header from the subsequent message. + This prevents a certain class of denial of service + attack, arguably gives more reasonable semantics, and + moves things more towards what will probably become a + network standard. Suggested by Christopher Davis of + Kapor Enterprises. + Add a "noreceipts" privacy flag to turn off all return receipts + without recompiling. + Avoid printing ESMTP parameters as part of the error message + if there are errors during parsing. This change is + purely cosmetic. + Avoid sending out error messages during the collect phase of + SMTP; there is an MVS mailer from UCLA that gets + confused by this. Of course, I think it's their bug.... + Check for the $j macro getting undefined, losing a dot, or getting + lost from $=w in the daemon before accepting a connection; + if it is, it dumps state, prints a LOG_ALERT message, + and drops core for debugging. This is an attempt to + track down a bug that I thought was long since gone. + If you see this, please forward the log fragment to + sendmail@sendmail.ORG. + Change OLD_NEWDB from a #ifdef to a #if so it can be turned off + with -DOLD_NEWDB=0 on the command line. From Christophe + Wolfhugel. + Instead of trying to truncate the listen queue for the server + SMTP port when the load average is too high, just close + the port completely and reopen it later as needed. + This ensures that the other end gets a quick "connection + refused" response, and that the connection can be + recovered later. In particular, some socket emulations + seem to get confused if you tweak the listen queue + size around and can never start listening to connections + again. The down side is that someone could start up + another daemon process in the interim, so you could + have multiple daemons all not listening to connections; + this could in turn cause the sendmail.pid file to be + incorrect. A better approach might be to accept the + connection and give a 421 code, but that could break + other mailers in mysterious ways and have paging behaviour + implications. + Fix a glitch in TCP-level debugging that caused flag 16.101 to + set debugging on the wrong socket. From Eric Wassenaar. + When creating a df* temporary file, be sure you truncate any + existing data in the file -- otherwise system crashes + and the like could result in extra data being sent. + DOC: Replace the CHANGES-R5-R8 readme file with a paper in the + doc directory. This includes some additional + information. + CONFIG: change UUCP rules to never add $U! or $k! on the front + of recipient envelope addresses. This should have been + handled by the $&h trick, but broke if people were + mixing domainized and UUCP addresses. They should + probably have converted all the way over to uucp-uudom + instead of uucp-{new,old}, but the failure mode was to + loop the mail, which was bad news. + Portability fixes: + Newer BSDI systems (several people). + Older BSDI systems from Christophe Wolfhugel. + Intergraph CLIX, from Paul Southworth of CICNet. + UnixWare, from Evan Champion. + NetBSD from Adam Glass. + Solaris from Quentin Campbell of the University of + Newcastle upon Tyne. + IRIX from Dean Cookson and Bill Driscoll of Mitre + Corporation. + NCR 3000 from Kevin Darcy of Chrysler Financial Corporation. + SunOS (it has setsid() and setvbuf() calls) from + Jonathan Kamens of OpenVision Technologies. + HP-UX from Tor Lillqvist. + New Files: + src/Makefile.CLIX + src/Makefile.NCR3000 + doc/changes/Makefile + doc/changes/changes.me + doc/changes/changes.ps + +8.6.8/8.6.6 94/03/21 + SECURITY: it was possible to read any file as root using the + E (error message) option. Reported by Richard Jones; + fixed by Michael Corrigan and Christophe Wolfhugel. + +8.6.7/8.6.6 94/03/14 + SECURITY: it was possible to get root access by using wierd + values to the -d flag. Thanks to Alain Durand of + INRIA for forwarding me the notice from the bugtraq + list. + +8.6.6/8.6.6 94/03/13 + SECURITY: the ability to give files away on System V-based + systems proved dangerous -- don't run as the owner + of a :include: file on a system that allows giveaways. + Unfortunately, this also applies to determining a + valid shell. + IMPORTANT: Previous versions weren't expiring old connections + in the connection cache for a long time under some + circumstances. This could result in resource exhaustion, + both at your end and at the other end. This checks the + connections for timeouts much more frequently. From + Doug Anderson of NCSC. + Fix a glitch that snuck in that caused programs to be run as + the sender instead of the recipient if the mail was + from a local user to another local user. From + Motonori Nakamura of Kyoto University. + Fix "wildcard" on /etc/shells matching -- instead of looking + for "*", look for "/SENDMAIL/ANY/SHELL/". From + Bryan Costales of ICSI. + Change the method used to declare the "statfs" availability; + instead of HASSTATFS and/or HASUSTAT with a ton of + tweaking in conf.c, there is a single #define called + SFS_TYPE which takes on one of six values (SFS_NONE + for no statfs availability, SFS_USTAT for the ustat(2) + syscall, SFS_4ARGS for a four argument statfs(2) call, + and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument + statfs(2) call with the declarations in <sys/vfs.h>, + <sys/mount.h>, or <sys/statfs.h> respectively). + Fix glitch in NetInfo support that could return garbage if + there was no "/locations/sendmail" property. From + David Meyer of the University of Virginia. + Change HASFLOCK from defined/not-defined to a 0/1 definition + to allow Linux to turn it off even though it is a + BSD-like system. + Allow setting of "ident" timeout to zero to turn off the ident + protocol entirely. + Make 7-bit stripping local to a connection (instead of to a + mailer); this allows you to specify that SMTP is a + 7-bit channel, but revert to 8-bit should it advertise + that it supports 8BITMIME. You still have to specify + mailer flag 7 to get this stripping at all. + Improve makesendmail script so it handles more cases automatically. + Tighten up restrictions on taking ownership of :include: files + to avoid problems on systems that allow you to give away + files. + Fix a problem that made it impossible to rebuild the alias + file if it was on a read-only file system. From + Harry Edmon of the University of Washington. + Improve MX randomization function. From John Gardiner Myers + of CMU. + Fix a minor glitch causing a bogus message to be printed (used + %s instead of %d in a printf string for the line number) + when a bad queue file was read. From Harry Edmon. + Allow $s to remain NULL on locally generated mail. I'm not + sure this is necessary, but a lot of people have complained + about it, and there is a legitimate question as to whether + "localhost" is legal as an 822-style domain. + Fix a problem with very short line lengths (mailer L= flag) in + headers. This causes a leading space to be added onto + continuation lines (including in the body!), and also + tries to wrap headers containing addresses (From:, To:, + etc) intelligently at the shorter line lengths. Problem + Reported by Lars-Johan Liman of SUNET Operations Center. + Log the real user name when logging syserrs, since these can have + security implications. Suggested by several people. + Fix address logging of cached connections -- it used to always + log the numeric address as zero. This is a somewhat + bogus implementation in that it does an extra system + call, but it should be an inexpensive one. Fix from + Motonori Nakamura. + Tighten up handling of short syslog buffers even more -- there + were cases where the outgoing relay= name was too long + to share a line with delay= and mailer= logging. + Limit the overhead on split envelopes to one open file descriptor + per envelope -- previously the overhead was three + descriptors. This was in response to a problem reported + by P{r (Pell) Emanuelsson. + Fixes to better handle the case of unexpected connection closes; + this redirects the output to the transcript so the info + is not lost. From Eric Wassenaar. + Fix potential string overrun if you macro evaluate a string that + has a naked $ at the end. Problem noted by James Matheson + <jmrm@eng.cam.ac.uk>. + Make default error number on $#error messages 553 (``Requested + action not taken: mailbox name not allowed'') instead of + 501 (``Syntax error in parameters or arguments'') to + avoid bogus "protocol error" messages. + Strip off any existing trailing dot on names during $[ ... $] + lookup. This prevents it from ending up with two dots + on the end of dot terminated names. From Wesley Craig + of the University of Michigan and Bryan Costales of ICSI. + Clean up file class reading so that the debugging information is + more informative. It hadn't been using setclass, so you + didn't see the class items being added. + Avoid core dump if you are running a version of sendmail where + NIS is compiled in, and you specify an NIS map, but + NIS is not running. Fix from John Oleynick of + Rutgers. + Diagnose bizarre case where res_search returns a failure value, + but sets h_errno to a success value. + Make sure that "too many hops" messages are considered important + enough to send an error to the Postmaster (that is, the + address specified in the P option). This fix should + help problems that cause the df file to be left around + sometimes -- unfortunately, I can't seem to reproduce + the problem myself. + Avoid core dump (null pointer reference) on EXPN command; this + only occurred if your log level was set to 10 or higher + and the target account was an alias or had a .forward file. + Problem noted by Janne Himanka. + Avoid "denial of service" attacks by someone who is flooding your + SMTP port with bad commands by shutting the connection + after 25 bad commands are issued. From Kyle Jones of + UUNET. + Fix core dump on error messages with very long "to" buffers; + fmtmsg overflows the message buffer. Fixed by trimming + the to address to 203 characters. Problem reported by + John Oleynick. + Fix configuration for HASFLOCK -- there were some spots where + a #ifndef was incorrectly #ifdef. Pointed out by + George Baltz of the University of Maryland. + Fix a typo in savemail() that could cause the error message To: + lists to be incorrect in some places. From Motonori + Nakamura. + Fix a glitch that can cause duplicate error messages on split + envelopes where an address on one of the lists has a + name server failure. Fix from Voradesh Yenbut of the + University of Washington. + Fix possible bogus pointer reference on ESMTP parameters that + don't have an ``=value'' part. + CNAME loops caused an error message to be generated, but also + re-queued the message. Changed to just re-queue the + message (it's really hard to just bounce it because + of the wierd way the name server works in the presence + of CNAME loops). Problem noted by James M.R.Matheson + of Cambridge University. + Avoid giving ``warning: foo owned process doing -bs'' messages + if they use ``MAIL FROM:<foo>'' where foo is their true + user name. Suggested by Andreas Stolcke of ICSI. + Change the NAMED_BIND compile flag to be a 0/1 flag so you can + override it easily in the Makefile -- that is, you can + turn it off using -DNAMED_BIND=0. + If a gethostbyname(...) of an address with a trailing dot fails, + try it without the trailing dot. This is because if + you have a version of gethostbyname() that falls back + to NIS or the /etc/hosts file it will fail to find + perfectly reasonable names that just don't happen to + be dot terminated in the hosts file. You don't want to + strip the dot first though because we're trying to ensure + that country names that match one of your subdomains get + a chance. + PRALIASES: fix bogus output on non-null-terminated strings. + From Bill Gianopoulos of Raytheon. + CONFIG: Avoid rewriting anything that matches $w to be $j. + This was in code intended to only catch the self-literal + address (that is, [1.2.3.4], where 1.2.3.4 is your + IP address), but the code was broken. However, it will + still do this if $M is defined; this is necessary to + get client configurations to work (sigh). Note that this + means that $M overrides :mailname entries in the user + database! Problem noted by Paul Southworth. + CONFIG: Fix definition of Solaris help file location. From + Steve Cliffe <steve@gorgon.cs.uow.edu.au>. + CONFIG: Fix bug that broke news.group.USENET mappings. + CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX, + and USENET_MAILER_MAX to tweak the maximum message + size for various mailers. + CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0] + instead of assuming that it is "inews" for consistency + with other mailers. From Michael Corrigan of UC San Diego. + CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB, + qualify the address in the SMTP envelope as user@{relay|hub} + instead of user@$j. From Bill Wisner of The Well. + CONFIG: Fix route-addr syntax in nullrelay configuration set. + CONFIG: Don't turn off case mapping of user names in the local + mailer for IRIX. This was different than most every other + system. + CONFIG: Avoid infinite loops on certainly list:; syntaxes in + envelope. Noted by Thierry Besancon + <besancon@excalibur.ens.fr>. + CONFIG: Don't include -z by default on uux line -- most systems + don't want it set by default. Pointed out by Philippe + Michel of Thomson CSF. + CONFIG: Fix some bugs with mailertables -- for example, if your + host name was foo.bar.ray.com and you matched against + ".ray.com", the old implementation bound %1 to "bar" + instead of "foo.bar". Also, allow "." in the mailertable + to match anything -- essentially, take over SMART_HOST. + This also moves matching of explicit local host names + before the mailertable so they don't have to be special + cased in the mailertable data. Reported by Bill + Gianopoulos of Raytheon; the fix for the %1 binding + problem was contributed by Nicholas Comanos of the + University of Sydney. + CONFIG: Don't include "root" in class $=L (users to deliver + locally, even if a hub or relay exists) by default. + This is because of the known bug where definition of + both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore + both and deliver into the local mailbox. + CONFIG: Move up bitdomain and uudomain handling so that they + are done before .UUCP class matching; uudomain was + reported as ineffective before. This also frees up + diversion 8 for future use. Problem reported by Kimmo + Suominen. + CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4]) + into host names. As pointed out by Jonathan Kamens, + these are often used because either the forward or reverse + mapping is broken; this translation makes it broken again. + DOC: Clarify $@ and $: in the Install & Op Guide.

From + Bob Campbell at U.C. Berkeley. + Security fix: group ids were not completely set when programs + were invoked. This caused programs to have group + permissions they should not have had (usually group + daemon instead of their own group). In particular, + Perl scripts would refuse to run. + Security: check to make sure files that are written are not + symbolic links (at least under some circumstances). + Although this does not respond to a specific known + attack, it's just a good idea. Suggested by + Christian Wettergren. + Security fix: if a user had an NFS mounted home directory on + a system with a restricted shell listed in their + /etc/passwd entry, they could still execute any + program by putting that in their .forward file. + This fix prevents that by insisting that their shell + appear in /etc/shells before allowing a .forward to + execute a program or write a file. You can disable + this by putting "*" in /etc/shells. It also won't + permit world-writable :include: files to reference + programs or files (there's no way to disable this). + These behaviours are only one level deep -- for + example, it is legal for a world-writable :include: + file to reference an alias that writes a file, on + the assumption that the alias file is well controlled. + Security fix: root was not treated suspiciously enough when + looking into subdirectories. This would potentially + allow a cracker to examine files that were publically + readable but in a non-publically searchable directory. + Fix a problem that causes an error on QUIT on a cached + connection to create problems on the current job. + These are typically unrelated, so errors occur in + the wrong place. + Reset CurrentLA in sendall() -- this makes sendmail queue + runs more responsive to load average, and fixes a + problem that ignored the load average in locally + generated mail. From Eric Wassenaar. + Fix possible core dump on aliases with null LHS. From + John Orthoefer of BB&N. + Revert to using flock() whenever possible -- there are just + too many bugs in fcntl() locking, particularly over + NFS, that cause sendmail to fail in perverse ways. + Fix a bug that causes the connection cache to get confused + when sending error messages. This resulted in + "unexpected close" messages. It should fix itself + on the following queue run. Problem noted by + Liudvikas Bukys of the University of Rochester. + Include $k in $=k as documented in the Install & Op Guide. + This seems odd, but it was documented.... From + Michael Corrigan of UCSD. + Fix problem that caused :include:s from alias files to be + forced to be owned by root instead of daemon + (actually DefUid). From Tim Irvin. + Diagnose unrecognized I option values -- from Mortin Forssen + of the Chalmers University of Technology. + Make "error" mailer work consistently when there is no error + code associated with it -- previously it returned OK + even though there was a real problem. Now it assumes + EX_UNAVAILABLE. + Fix bug that caused the last header line of messages that had + no body and which were terminated with EOF instead of + "." to be discarded. Problem noted by Liudvikas Bukys. + Fix core dump on SMTP mail to programs that failed -- it tried + to go to a "next MX host" when none existed, causing + a core dump. From der Mouse at McGill University. + Change IDENTPROTO from a defined/not defined to a 0/1 switch; + this makes it easier to turn it off (using + -DIDENTPROTO=0 in the Makefile). From der Mouse. + Fix YP_MASTER_NAME store to use the unupdated result of + gethostname() (instead of myhostname(), which tries + to fully qualify the name) to be consistent with + SunOS. If your hostname is unqualified, this fixes + transfers to slave servers. Bug noted by Keith + McMillan of Ameritech Services, Inc. + Fix Ultrix problem: gethostbyname() can return a very large + (> 500) h_length field, which causes the sockaddr + to be trashed. Use the size of the sockaddr instead. + Fix from Bob Manson of Ohio State. + Don't assume "-a." on host lookups if NAMED_BIND is not + defined -- this confuses gethostbyname on hosts + file lookups, which doesn't understand the trailing + dot convention. + Log SMTP server subprocesses that die with a signal instead + of from a clean exit. + If you don't have option "I" set, don't assume that a DNS + "host unknown" message is authoritative -- it + might still be found in /etc/hosts. + Fix a problem that would cause Deferred: messages to be sent + as the subject of an error message, even though the + actual cause of a message was more severe than that. + Problem noted by Chris Seabrook of OSSI. + Fix race condition in DBM alias file locking. From Kyle + Jones of UUNET. + Limit delivery syslog line length to avoid bugs in some + versions of syslog(3). This adds a new compile time + variable SYSLOG_BUFSIZE. From Jay Plett of Princeton + University, which is in turn derived from IDA. + Fix quotes inside of comments in addresses -- previously + it insisted that they be balanced, but the 822 spec + says that they should be ignored. + Dump open file state to syslog upon receiving SIGUSR1 (for + debugging). This also evaluates ruleset 89, if set + (with the null input), and logs the result. This + should be used sparingly, since the rewrite process + is not reentrant. + Change -qI, -qR, and -qS flags to be case-insensitive as + documented in the Bat Book. + If the mailer returned EX_IOERR or EX_OSERR, sendmail did not + return an error message and did not requeue the message. + Fix based on code from Roland Dirlewanger of + Reseau Regional Aquarel, Bordeaux, France. + Fix a problem that caused a seg fault if you got a 421 error + code during some parts of connection initialization. + I've only seen this when talking to buggy mailers on + the other end, but it shouldn't give a seg fault in + any case. From Amir Plivatsky. + Fix core dump caused by a ruleset call that returns null. + Fix from Bryan Costales of ICSI. + Full-Name: field was being ignored. Fix from Motonori Nakamura + of Kyoto University. + Fix a possible problem with very long input lines in setproctitle. + From P{r Emanuelsson. + Avoid putting "This is a warning message" out on return receipts. + Suggested by Douglas Anderson. + Detect loops caused by recursive ruleset calls. Suggested by + Bryan Costales. + Initialize non-alias maps during alias rebuilds -- they may be + needed for parsing. Problem noted by Douglas Anderson. + Log sender address even if no message was collected in SMTP + (e.g., if all RCPTs failed). Suggested by Motonori + Nakamura. + Don't reflect the owner-list contents into the envelope sender + address if the value contains ", :, /, or | (to avoid + illegal addresses appearing there). + Efficiency hack for toktype macro -- from Craig Partridge of + BB&N. + Clean up DNS error printing so that a host name is always + included. + Remember to set $i during queue runs. Reported by Stephen + Campbell of Dartmouth University. + If the environment variable HOSTALIASES is set, use it during + canonification as the name of a file with per-user host + translations so that headers are properly mapped. Reported + by Anne Bennett of Concordia University. + Avoid printing misleading error message if SMTP mailer (not + using [IPC]) should die on a core dump. + Avoid incorrect diagnosis of "file 1 closed" when it is caused + by the other end closing the connection. From + Dave Morrison of Oracle. + Improve several of the error messages printed by "mailq" + to include a host name or other useful information. + Add NetInfo preliminary support for NeXT systems. From Vince + DeMarco. + Fix a glitch that sometimes caused :include:s that pointed to + NFS filesystems that were down to give an "aliasing/ + forwarding loop broken" message instead of queueing + the message for retry. Noted by William C Fenner of + the NRL Connection Machine Facility. + Fix a problem that could cause a core dump if the input sequence + had (or somehow acquired) a \231 character. + Make sure that route-addrs always have <angle brackets> around + them in non-SMTP envelopes (SMTP envelopes already do + this properly). + Avoid wierd headers on unbalanced punctuation of the form: + ``Joe User <user)'' -- this caused reference to the + null macro. Fix from Rick McCarty of IO.COM. + Fix a problem that caused an alias "user: user@local.host" to + not have the QNOTREMOTE bit set; this caused configs + to act as if FEATURE(notsticky) was defined even when + it was not. The effect of the problem was to make it + very hard to to set up satellite sites that had a few + local accounts, with everything else forwarded to a + corporate hub. Reported by Detlef Drewanz of the + University of Rostock and Mark Frost of NCD. + Change queuing to not call rulesets 3, {1 or 2}, 4 on header + addresses. This is more efficient (fewer name server + calls) and fixes certain unusual configurations, such + as those that have ruleset 4 do something that is + non-idempotent unless a mailer-specific ruleset did + something else. Problem reported by Brian J. Coan + of the Institute for Global Communications. + Fix the "obsolete argument" routine in main to better understand + new arguments. For example, if you used ``sendmail + -C config -v -q'' it would choke on the -q because + the -C would stop looking for old-format arguments. + Fix the code that was intended to allow two users to forward their + mail to the same program and have them appear unique. + Portability fixes for: + SCO UNIX from Murray Kucherawy. + SCO Open Server 3.2v4 from Philippe Brand. + System V Release 4 from Rick Ellis and others. + OSF/1 from Steve Campbell. + DG/UX from Ben Mesander of the USGS and Bryan Curnutt + of Stoner Associates. + Motorola SysV88 from Kevin Johnson of Motorola. + Solaris 2.3 from Casper H.S.

From + Irving Reid of the University of Toronto. + CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1 + from Markku Toijala of ICL Personal Systems Oy. + CONFIG: Add trailing "." on pseudo-domains for consistency; + this fixes a problem (noted by Al Whaley of Sunnyside) + that made it hard to recognize your own pseudodomain + names. + CONFIG: catch "@host" syntax errors (i.e., null local-parts) + rather than letting them get "local configuration + error"s. Problem noted by John Gardiner Myers. + CONFIG: add uucp-uudom mailer variant, based on code posted + by Spider Boardman <spider@Orb.Nashua.NH.US>; this + has uucp-dom semantics but old UUCP syntax. This + also permits "uucp-old" as an alias for "uucp" and + "uucp-new" as a synonym for "suucp" for consistency. + CONFIG: add POP mailer support (from Kimmo Suominen + <kim@grendel.lut.fi>). + CONFIG: drop CSNET_RELAY support -- CSNET is long gone. + CONFIG: fix bug caused with domain literal addresses (e.g., + ``[128.32.131.12]'') when FEATURE(allmasquerade) + was set; it would get an additional @masquerade.host + added to the address. Problem noted by Peter Wan + of Georgia Tech. + CONFIG: make sure that the local UUCP name is in $=w. From + Jim Murray of Stratus. + CONFIG: changes to UUCP rewriting to simulate IDA-style "V" + mailer flag.

From Mark Delany. + MAILSTATS: print sums of columns (total messages & kbytes + in and out of the system). From Tom Ferrin of UC + San Francisco Computer Graphics Lab. + SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES: + On HP-UX, /etc/sendmail.cf has been moved to + /usr/lib/sendmail.cf to match HP sendmail. + Permissions have been tightened up on world-writable + :include: files and accounts that have shells + that are not listed in /etc/shells.

Problem reported by Richard Liu. + Immediately diagnose bogus sender addresses in SMTP. This + makes quite certain that crackers can't use this + class of attack. + Reliability Fix: check return value from fclose() and fsync() + in a few critical places. + Minor problem in initsys() that reversed a condition for + redirecting the output channel on queue runs. It's + not clear this code even does anything. From Eric + Wassenaar of the Dutch National Institute for Nuclear + and High-Energy Physics. + Fix some problems that caused queue runs to do "too much work", + such as double-reading the Errors-To: header. From + Eric Wassenaar. + Error messages on writing the temporary file (including the + data file) were getting suppressed in SMTP -- this + fix causes them to be properly reported. From Eric + Wassenaar. + Some changes to support AF_UNIX sockets -- this will only + really become relevant in the next release, but some + people need it for local patches. From Michael + Corrigan of UC San Diego. + Use dynamically allocated memory (instead of static buffers) + for macros defined in initsys() and settime(); since + these can have different values depending on which + envelope they are in. From Eric Wassenaar. + Improve logging to show ctladdr on to= logging; this tells you + what uid/gid processes ran as. + Fix a problem that caused error messages to be discarded if + the sender address was unparseable for some reason; + this was supposed to fall back to the "return to + postmaster" case. + Improve aliaswait backoff algorithm. + Portability patches for Linux (8.6.3 required another header + file) (from Karl London) and SCO UNIX. + CONFIG: patch prog mailer to not strip host name off of envelope + addresses (so that it matches local again). From + Christopher Davis. + CONFIG: change uucp-dom mailer so that "<>" translates to $n; + this prevents uux from seeing lines with null names like + ``From Sat Oct 30 14:55:31 1993''. From Motonori + Nakamura of Kyoto University. + CONFIG: handle <list:;> syntax correctly. This isn't legal, but + it shouldn't fail miserably. From Motonori Nakamura. + +8.6.2/8.6.2 93/10/15 + Put a "successful delivery" message in the transcript for + addresses that get return-receipts. + Put a prominent "this is only a warning" message in warning + messages -- some people don't read carefully enough + and end up sending the message several times. + Include reason for temporary failure in the "warning" return + message. Currently, it just says "cannot send for + four hours". + Fix the "Original message received" time generated for + returntosender messages. It was previously listed as + the current time. Bug reported by Eric Hagberg of + Cornell University Medical College. + If there is an error when writing the body of a message, + don't send the trailing dot and wait for a response + in sender SMTP, as this could cause the connection to + hang up under some bizarre circumstances. From Eric + Wassenaar. + Fix some server SMTP synchronization problems caused when + connections fail during message collection. From + Eric Wassenaar. + Fix a problem that can cause srvrsmtp to reject mail if the + name server is down -- it accepts the RCPT but rejects + the DATA command. Problem reported by Jim Murray of + Stratus. + Fix a problem that can cause core dumps if the config file + incorrectly resolves to a null hostname. Reported by + Allan Johannesen of WPI. + Non-root use of -C flag, dangerous -f flags, and use of -oQ + by non-root users were not put into + X-Authentication-Warning:s as intended because the + config file hadn't set the PrivacyFlags yet. Fix + from Sven-Ove Westberg of the University of Lulea. + Under very odd circumstances, the alias file rebuild code + could get confused as to whether a database was + open or not. + Check "vendor code" on the end of V lines -- this is + intended to provide a hook for vendor-specific + configuration syntax.

Pointed out by Michael Corrigan of UCSD. + Announce name of host we are chatting when we get errors; this + is an IDA-ism suggested by Christophe Wolfhugel. + Portability fixes for Alpha OSF/1 (from Anthony Baxter of the + Australian Artificial Intelligence Institute), SCO Unix + (from Murray Kucherawy of Hookup Communication Corp.), + NeXT (from Vince DeMarco and myself), Linux (from + Karl London <karl@borg.demon.co.uk>), BSDI (from + Christophe Wolfhugel, and SVR4 on Dell (from Kimmo + Suominen), AUX 3.0 on Macintosh, and ANSI C compilers. + Some changes to get around gcc optimizer bugs. From Takahiro + Kanbe. + Fix error recovery in queueup if another tf file of the same + name already exists. Problem stumbled over by Bill + Wisner of The Well. + Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes. + Problem noted by Keith McMillan of Ameritech Services. + Deal with group permissions properly when opening .forward and + :include: files. This relaxes the 8.1C restrictions + slightly more. This includes proper setting of groups + when reading :include: files, allowing you to read some + files that you should be able to read but have previously + been denied unless you owned them or they had "other" + read permission. + Make certain that $j is in $=w (after the .cf is read) so that + if the user is forced to override some silly system, + MX suppression will still work. + Fix a couple of efficiency problems where newstr was double- + calling expensive routines. In at least one case, it + wasn't guaranteed that they would always return the + same result. Problem noted by Christophe Wolfhugel. + Fix null pointer dereference in putoutmsg -- only on an error + condition from a non-SMTP mailer. From Motonori + Nakamura. + Macro expand "C" line class definitions before scanning so that + "CX $Z" works. + Fix problem that caused error message to be sent while still + trying to send the original message if the connection + is closed during a DATA command after getting an error + on an RCPT command (pretty obscure). Problem reported + by John Myers of CMU. + Fix reply to NOOP to be 250 instead of 200 -- this is a long + term bug. + Fix a nasty bug causing core dumps when returning the "warning: + cannot deliver for N hours -- will keep trying" message; + it only occurred if you had PostMasterCopy set and + only on some architectures. Although sendmail would + keep trying, it would send error messages on each + queue interval. This is an important fix. + Allow u and g options to take user and group names respectively. + Don't do a chdir into the queue directory in -bt mode to make + ruleset testing a bit easier. + Don't allow users to turn off logging (using -oL) on the command + line -- command line can only raise, not lower, logging + level. + Set $u to the original recipient on the SMTP transaction or on + the command line. This is only done if there is exactly + one recipient. Technically, this does not meet the + specs, because it does not guarantee a domain on the + address. + Fix a problem that dumped error messages on bad addresses if + you used the -t flag. Problem noted by Josh Smith of + Harvey Mudd College. + Given an address such as ``<foo> <bar>'', auto-quote the first + ``<foo>'' part, giving ``"<foo>" <bar>''. This is to + avoid the problem of people who use angle brackets in + their full name information. + Fix a null pointer dereference if you set option "l", have + an Errors-To: header in the message, and have Errors-To: + defined in the config file H lines. From J.R. Oldroyd. + Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get + wrong when compiling. Suggested by Rick McCarty of TI. + Fix a problem that could pass negative SIZE parameter if the + df file got lost; this would cause servers to always + give a temporary failure, making the problem even worse. + Problem noted by Allan Johannesen of WPI. + Add "ident" timeout (one of the "r" option selectors) for IDENT + protocol timeouts (30s default). Requested by Murray + Kucherawy of HookUp Communication Corp. to handle bogus + PC TCP/IP implementations. + Change $w default definition to be just the first component of + the domain name on config level 5. The $j macro defaults + to the FQDN; $m remains as before. This lets well-behaved + config files use any of the short, long, or subdomain + names. + Add makesendmail script in src to try to automate multi-architecture + builds. I know, this is sub-optimal, but it is still + helpful. + Fix very obscure race condition that can cause a queue run to + get a queue file for an already completed job. This + problem has existed for years. Problem noted by the + long suffering Allan Johannesen of WPI. + Fix a problem that caused the raw sender name to be passed to + udbsender instead of the canonified name -- this caused + it to sometimes miss records that it should have found. + Relax check of name on HELO packet so that a program using -bs + that claims to be itself works properly. + Restore rewriting of $: part of address through 2, R, 4 in + buildaddr -- this requires passing a lot of flags to get + it right. Unlike old versions, this ONLY rewrites + recipient addresses, not sender addresses. + Fix a bug that caused core dumps in config files that cannot + resolve /file/name style addresses. Fix from Jonathan + Kamens of OpenVision Technologies. + Fix problem with fcntl locking that can cause error returns to + be lost if the lock is lost; this required fully + queueing everything, dropping the envelope (so errors + would get returned), and then re-reading the queue from + scratch. + Fix a problem that caused aliases that redefine an otherwise + true address to still send to the original address + if and only if the alias failed in certain bizarre + ways (e.g, if they pointed at a list:; syntax address). + Problem pointed out by Jonathan Kamens. + Remove support for frozen configuration files. They caused + more trouble than it was worth. + Fix problem that can cause error messages to get ignored when + using both -odb and -t flags. Problem noted by Rob + McNicholas at U.C. Berkeley. + Include all "normal" variations on hostname in $=w. For example, + if the host name is vangogh.cs.berkeley.edu, $=w will + contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu. + Add "restrictqrun" privacy flag -- without this, anyone can run + the queue. + Reset SmtpPhase global on initial connection creation so that + messages don't come out with stale information. + Pass an "ext" argument to lockfile so that error/log messages + will properly reflect the true filename being locked. + Put all [...] address forms into $=w -- this eliminates the need + for MAXIPADDR in conf.h. Suggested by John Gardiner + Myers of CMU. + Fix a bug that can cause qf files to be left around even after + an SMTP RSET command. Problem and fix from Michael + Corrigan. + Don't send a PostMasterCopy to errors when the Precedence: is + negative. Error reports still go to the envelope + sender address. + Add LA_SHORT for load averages. + Lock sendmail.st file when posting statistics. + Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to + set the size of the TCP send and receive buffers; if you + run over a slow slip line you may need to set these down + (although it would be better to fix the SLIP implementation + so that it's not necessary to recompile every program + that does bulk data transfer). + Allow null defaults on $( ... $) lookups. Problem reported by + Amir Plivatsky. + Diagnose crufty S and V config lines. This resulted from an + observation that some people were using the SITE macro + without the SITECONFIG macro first, which was causing + bogus config files that were not caught. + Fix makemap -f flag to turn off case folding (it was turning it + on instead). THIS IS A USER VISIBLE CHANGE!!! + Fix a problem that caused multiple error messages to be sent if + you used "sendmail -t -oem -odb", your system uses fcntl + locking, and one of the recipient addresses is unknown. + Reset uid earlier in include() so that recursive .forwards or + :include:s don't use the wrong uid. + If file descriptor 0, 1, or 2 was closed when sendmail was + called, the code to recover the descriptor was broken. + This sometimes (only sometimes) caused problems with the + alias file. Fix from Motonori Nakamura. + Fix a problem that caused aliaswait to go into infinite recursion + if the @:@ metasymbol wasn't found in the alias file. + Improve error message on newaliases if database files cannot be + opened or if running with no database format defined. + Do a better estimation of the size of error messages when NoReturn + is set. Problem noted by P{r (Pell) Emanuelsson. + Fix a problem causing the "c" option (don't connect to expensive + mailers) to be ignored in SMTP. Problem noted and the + solution suggested by Robert Elz of Munnari University. + Improve connection caching algorithm by passing "[host]" to + hostsignature, which strips the square brackets and + returns the real name. This allows mailertable entries + to match regular entries. + Re-enable Return-Receipt-To: -- people seem to want this stupid + feature, even if it doesn't work right. + Catch and log attempts to try the "wiz" command in server SMTP. + This also ups the log level from LOG_NOTICE to LOG_CRIT. + Be more generous at assigning $z to the home directory -- do this + for programs that are specified through a .forward file. + Fix from Andrew Chang of Sun Microsystems. + Always save a fatal error message in preference to a non-fatal + error message so that the "subject" line of return + messages is the best possible. + CONFIG: reduce the number of quotes needed to quote configuration + parameters with commas: two quotes should work now, e.g., + define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local''). + CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom + connections (domain-ized UUCP). + CONFIG: fix bug in default maps (-o must be before database file + name). Pointed out by Christophe Wolfhugel. + CONFIG: add FEATURE(nodns) to state that we are not relying on + DNS. This would presumably be used in UUCP islands. + CONFIG: add OSTYPE(nextstep) and OSTYPE(linux). + CONFIG: log $u in Received: line. This is in technical violation + of the standards, since it doesn't guarantee a domain + on the address. + CONFIG: don't assume "m" in local mailer flags -- this means that + if you redefine LOCAL_MAILER_FLAGS you will have to include + the "m" flag should you want it. Apparently some Solaris 2.2 + installations can't handle multiple local recipients. + Problem noted by Josh Smith. + CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults). + CONFIG: change default version level from 4 to 5. + CONFIG: add FEATURE(nullclient) to create a config file that + forwards all mail to a hub without ever looking at the + addresses in any detail. + CONFIG: properly strip mailer: information off of relays when + used to change .BITNET form into %-hack form. + CONFIG: fix a problem that caused infinite loops if presented + with an address such as "!foo". + CONFIG: check for self literal (e.g., [128.32.131.12]) even if + the reverse "PTR" mapping is broken. There's a better + way to do this, but the change is fairly major and I + want to hold it for another release. Problem noted by + Bret Marquis. + +8.5/8.5 93/07/23 + Serious bug: if you used a command line recipient that was unknown + sendmail would not send a return message (it was treating + everything as though it had an SMTP-style client that + would do the return itself). Problem noted by Josh Smith. + Change "trymx" option in getcanonname() to ignore all MX data, + even during a T_ANY query. This actually didn't break + anything, because the only time you called getcanonname + with !trymx was if you already knew there were no MX + records, but it is somewhat cleaner. From Motonori + Nakamura. + Don't call getcanonname from getmxrr if you already know there + are no DNS records matching the name. + Fix a problem causing error messages to always include "The + original message was received ... from localhost". + The correct original host information is now included. + Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their + version of "test" doesn't have the -x flag). Change it + to use -f instead. From John Myers. + CONFIG: 8.4 mistakenly set the default SMTP-style mailer to + esmtp -- it should be smtp. + CONFIG: send all relayed mail using confRELAY_MAILER (defaults + to "relay" (a variant of "smtp") if MAILER(smtp) is used, + else "suucp" if MAILER(uucp) is used, else "unknown"); + this cleans up the configs somewhat. This fixes a serious + problem that caused route-addrs to get mistaken as relays, + pointed out by John Myers. WARNING: this also causes + the default on SMART_HOST to change from "suucp" to + "relay" if you have MAILER(smtp) specified. + +8.4/8.4 93/07/22 + Add option `w'. If you receive a message that comes to you because + you are the best (lowest preference) target of an MX, and + you haven't explicitly recognized the source MX host in + your .cf file, this option will cause you to try the target + host directly (as if there were no MX for it at all). If + `w' is not set, this case is a configuration error. + Beware: if `w' is set, senders may get bogus errors like + "message timed out" or "host unknown" for problems that + are really configuration errors. This option is + disrecommended, provided only for compatibility with + UIUC sendmail. + Fix a problem that caused the incoming socket to be left open + when sendmail forks after the DATA command. This caused + calling systems to wait in FIN_WAIT_2 state until the + entire list was processed and the child closed -- a + potentially prodigious amount of time. Problem noted + by Neil Rickert. + Fix problem (created in 6.64) that caused mail sent to multiple + addresses, one of which was a bad address, to completely + suppress the sending of the message. This changes + handling of EF_FATALERRS somewhat, and adds an + EF_GLOBALERRS flag. This also fixes a potential problem + with duplicate error messages if there is a syntax error + in the header of a message that isn't noticed until late + in processing. Original problem pointed out by Josh Smith + of Harvey Mudd College. This release includes quite a bit + of dickering with error handling (see below). + Back out SMTP transaction if MAIL gets nested 501 error. This + will only hurt already-broken software and should help + humans. + Fix a problem that broke aliases when neither NDBM nor NEWDB were + compiled in. It would never read the alias file. + Repair unbalanced `)' and `>' (the "open" versions are already + repaired). + Logging of "done" in dropenvelope() was incorrect: it would + log this even when the queue file still existed. Change + this to only log "done" (at log level 11) when the + queue file is actually removed. From John Myers. + Log "lost connection" in server SMTP at log level 20 if there + is no pending transaction. Some senders just close the + connection rather than sending QUIT. + Fix a bug causing getmxrr to add a dot to the end of unqualified + domains that do not have MX records -- this would cause + the subsequent host name lookup to fail. The problem + only occurred if you had FEATURE(nocanonify) set. + Problem noted by Rick McCarty of Texas Instruments. + Fix invocation of setvbuf when passed a -X flag -- I had + unwittingly used an ANSI C extension, and this caused + core dumps on some machines. + Diagnose self-destructive alias loops on RCPT as well as EXPN. + Previously it just gave an empty send queue, which + then gave either "Need RCPT (recipient)" at the DATA + (confusing, since you had given an RCPT command which + returned 250) or just dropped the email, depending on + whether you were running VERBose mode. Now it usually + diagnoses this case as "aliasing/forwarding loop broken". + Unfortunately, it still doesn't adequately diagnose + some true error conditions. + Add internal concept of "warning messages" using 6xx codes. + These are not reported only to Postmaster. Unbalanced + parens, brackets, and quotes are printed as 653 codes. + They are always mapped to 5xx codes before use in SMTP. + Clean up error messages to tell both the actual address that + failed and the alias they arose from. This makes it + somewhat easier to diagnose problems. Difficulty noted + by Motonori Nakamura. + Fix a problem that inappropriately added a ctladdr to addresses + that shouldn't have had one during a queue run. This + caused error messages to be handled differently during + a queue run than a direct run. + Don't print the qf name and line number if you get errors during + the direct run of the queue from srvrsmtp -- this was + just extra stuff for users to crawl through. + Put command line flags on second line of pid file so you can + auto-restart the daemon with all appropriate arguments. + Use "kill `head -1 /etc/sendmail.pid`" to stop the + daemon, and "eval `tail -1 /etc/sendmail.pid`" to + restart it. + Remove the ``setuid(getuid())'' in main -- this caused the + IDENT daemon to screw up. This required that I change + HASSETEUID to HASSETREUID and complicate the mode + changing somewhat because both Ultrix and SunOS seem + to have a bug causing seteuid() to set the saved uid + as well as the effective. The program test/t_setreuid.c + will test to see if your implementation of setreuid(2) + is appropriately functional. + The FallBackMX (option V) handling failed to properly identify + fallback to yourself -- most of the code was there, + but it wasn't being enabled. Problem noted by Murray + Kucherawy of the University of Waterloo. + Change :include: open timeout from ETIMEDOUT to an internal + code EOPENTIMEOUT; this avoids adding "during SmtpPhase + with CurHostName" in error messages, which can be + confusing. Reported by Jonathan Kamens of OpenVision + Technologies. + Back out setpgrp (setpgid on POSIX systems) call to reset the + process group id. The original fix was to get around + some problems with recalcitrant MUAs, but it breaks + any call from a shell that creates a process group id + different from the process id. I could try to fix + this by diddling the tty owner (using tcsetpgrp or + equivalent) but this is too likely to break other + things. + Portability changes: + Support -M as equivalent to -oM on Ultrix -- apparently + DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs + instead of using standard flags. Oh joy. This + behaviour reported by Jon Giltner of University + of Colorado. + SGI IRIX -- this includes several changes that should + help other strict ANSI compilers. + SCO Unix -- from Murray Kucherawy of HookUp Communication + Corporation. + Solaris running the Sun C compiler (which despite the + documentation apparently doesn't define + __STDC__ by default). + ConvexOS from Eric Schnoebelen of Convex. + Sony NEWS workstations and Omron LUNA workstations from + Motonori Nakamura. + CONFIG: add confTRY_NULL_MX_LIST to set option `w'. + CONFIG: delete `C' and `e' from default SMTP mailers flags; + several people have made a good argument that this + creates more problems than it solves (although this + may prove painful in the short run). + CONFIG: generalize all the relays to accept a "mailer:host" + format. + CONFIG: move local processing in ruleset 0 into a new ruleset + 98 (8 on old sendmail). Domain literal [a.b.c.d] + addresses are also passed through this ruleset. + CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined, + internet-style addresses would "fall off the end" of + ruleset zero and be interpreted as local -- however, + the angle brackets confused the recursive call. + These are now diagnosed as "Unrecognized host name". + CONFIG: USENET rules weren't included in S0 because of a mistaken + ifdef(`_MAILER_USENET_') instead of + ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik + of SINTEF RUNIT, Oslo. + CONFIG: move up LOCAL_RULE_0 processing so that it happens very + early in ruleset 0; this allows .mc authors to bypass + things like the "short circuit" code for local addresses. + Prompted by a comment by Bill Wisner of The Well. + CONFIG: add confSMTP_MAILER to define the mailer used (smtp or + esmtp) to send SMTP mail. This allows you to default + to esmtp but use a mailertable or other override to + deal with broken servers. This logic was pointed out + to me by Bill Wisner. Ditto for confLOCAL_MAILER. + Changes to cf/sh/makeinfo.sh to make it portable to SVR4 + environments. Ugly as sin. + +8.3/8.3 93/07/13 + Fix setuid problems introduced in 8.2 that caused messages + like "Cannot create qfXXXXXX: Invalid argument" + or "Cannot reopen dfXXXXXX: Permission denied". This + involved a new compile flag "HASSETEUID" that takes + the place of the old _POSIX_SAVED_IDS -- it turns out + that the POSIX interface is broken enough to break + some systems badly. This includes some fixes for + HP-UX. Also fixes problems where the real uid is + not reset properly on startup (from Neil Rickert). + Fix a problem that caused timed out messages to not report the + addresses that timed out. Error messages are also more + "user friendly". + Drop required bandwidth on connections from 64 bytes/sec to + 16 bytes/sec. + Further Solaris portability changes -- doesn't require the BSD + compatibility library. This also adds a new + "HASGETDTABLESIZE" compile flag which can be used if + you want to use getdtablesize(2) instead of sysconf(2). + These are loosely based on changes from David Meyer at + University of Oregon. This now seems to work, at least + for quick test cases. + Fix a problem that can cause duplicate error messages to be + sent if you are in SMTP, you send to multiple addresses, + and at least one of those addresses is good and points + to an account that has a .forward file (whew!). + Fix a problem causing messages to be discarded if checkcompat() + returned EX_TEMPFAIL (because it didn't properly mark + the "to" address). Problem noted by John Myers. + Fix dfopen to return NULL if the open failed; I was depending + on fdopen(-1) returning NULL, which isn't the case. This + isn't serious, but does result in wierd error diagnoses. + From Michael Corrigan. + CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of + messages sent through UUCP-family mailers. Suggested + by Bill Wisner of The Well. + CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified, + include a "uucp-dom" mailer that uses domain-style + addressing. Suggested by Bill Wisner. + CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match + LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by + Christophe Wolfhugel. + CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel. + +8.2/8.2 93/07/11 + Don't drop out on config file parse errors in -bt mode. + On older configuration files, assume option "l" (use Errors-To + header) for back compatibility. NOTE: this DOES NOT + imply an endorsement of the Errors-To: header in any way. + Accept -x flag on AIX-3 as well as OSF/1. Why, why, why??? + Don't log errors on EHLO -- it isn't a "real" error for an old + SMTP server to give an error on this command, and + logging it in the transcript can be confusing. Fix + from Bill Wisner. + IRIX compatibility changes provided by Dan Rich + <drich@sandman.lerc.nasa.gov>. + Solaris 2 compatibility changes. Provided by Bob Cunningham + <bob@kahala.soest.hawaii.edu>, John Oleynick + <juo@klinzhai.rutgers.edu> + Debugging: -d17 was overloaded (hostsignature and usersmtp.c); + move usersmtp (smtpinit and smtpmailfrom) to -d18 to + match the other flags in that file. + Flush transcript before fork in mailfile(). From Eric Wassenaar. + Save h_errno in mci struct and improve error message display. + Changes from Eric Wassenaar. + Open /dev/null for the transcript if the create of the xf file + failed; this avoids at least one possible null pointer + reference in very wierd cases. From Eric Wassenaar. + Clean up statistics gathering; it was over-reporting because of + forks. From Eric Wassenaar. + Fix problem that causes old Return-Path: line to override new + Return-Path: line (conf.c needs H_FORCE to avoid + re-using old value). From Motonori Nakamura. + Fix broken -m flag in K definition -- even if -m (match only) + was specified, it would still replace the key with the + value. Noted by Rick McCarty of Texas Instruments. + If the name server timed out over several days, no "timed out" + message would ever be sent back. The timeout code + has been moved from markfailure() to dropenvelope() + so that all such failures should be diagnosted. Pointed + out by Christophe Wolfhugel and others. + Relax safefile() constraints: directories in an include or + forward path must be readable by self if the controlling + user owns the entry, readable by all otherwise (e.g., + when reading your .forward file, you have to own and + have X permssion in it; everyone needs X permission in + the root and directories leading up to your home); + include files must be readable by anyone, but need not + be owned by you. + If _POSIX_SAVED_IDS is defined, setuid to the owner before + reading a .forward file; this gets around some problems + on NFS mounts if root permission is not exported and + the user's home directory isn't x'able. + Additional NeXT portability enhancements from Axel Zinser. + Additional HP-UX portability enhancements from Brian Bullen. + Add a timeout around SMTP message writes; this assumes you can + get throughput of at least 64 bytes/second. Note that + this does not impact the "datafinal" default, which + is separate; this is just intended to work around + network clogs that will occur before the final dot + is sent. From Eric Wassenaar. + Change map code to set the "include null" flag adaptively -- + it initially tries both, but if it finds anything + matching without a null it never tries again with a + null and vice versa. If -N is specified, it never + tries without the null and creates new maps with a + null byte. If -O is specified, it never tries with + the null (for efficiency). If -N and -O are specified, + you get -NO (get it?) lookup at all, so this would + be a bad idea. If you don't specify either -N or -O, + it adapts. + Fix recognition of "same from address" so that MH submissions + will insert the appropriate full name information; + this used to work and got broken somewhere along the + way. + Some changes to eliminate some unnecessary SYSERRs in the + log. For example, if you lost a connection, don't + bother reporting that fact on the connection you lost. + Add some "extended debugging" flags to try to track down + why we get occassional problems with file descriptor + one being closed when execing a mailer; it seems to + only happen when there has been another error in the + same transaction. This requires XDEBUG, defined + by default in conf.h. + Add "-X filename" command line flag, which logs both sides of + all SMTP transactions. This is intended ONLY for + debugging bad implementations of other mailers; start + it up, send a message from a mailer that is failing, + and then kill it off and examine the indicated log. + This output is not intended to be particularly human + readable. This also adds the HASSETVBUF compile + flag, defaulted on if your compiler defines __STDC__. + CONFIG: change SMART_HOST to override an SMTP mailer. If you + have a local net that should get direct connects, you + will need to use LOCAL_NET_CONFIG to catch these hosts. + See cf/README for an example. + CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle + sites that don't use the -d flag. + CONFIG: hide recipient addresses as well as sender addresses + behind $M if FEATURE(allmasquerade) is specified; this + has been requested by several people, but can break + local aliases. For example, if you mail to "localalias" + this will be rewritten as "localalias@masqueradehost"; + although initial delivery will work, replies will be + broken. Use it sparingly. + CONFIG: add FEATURE(domaintable). This maps unqualified domains + to qualified domains in headers. I believe this is + largely equivalent to the IDA feature of the same name. + CONFIG: use $U as UUCP name instead of $k. This permits you + to override the "system name" as your UUCP name -- + in particular, to use domain-ized UUCP names. From + Bill Wisner of The Well. + CONFIG: create new mailer "esmtp" that always tries EHLO + first. This is currently unused in the config files, + but could be used in a mailertable entry. + +8.1C/8.1B 93/06/27 + Serious security bug fix: it was possible to read any file on + the system, regardless of ownership and permissions. + If a subroutine returns a fully qualified address, return it + immediately instead of feeding it back into rewriting. + This fixes a problem with mailertable lookups. + CONFIG: fix some M4 frotz (concat => CONCAT) + +8.1B/8.1A 93/06/12 + Serious bug fix: pattern matching backup algorithm stepped by + two tokens in classes instead of one. Found by Claus + Assmann at University of Kiel, Germany. + +8.1A/8.1A 93/06/08 + Another mailertable fix.... + +8.1/8.1 93/06/07 + 4.4BSD freeze. No semantic changes. + +6.65/6.34 93/06/06 + Fix some lintish problems. + Fix some cases where server SMTP behaved poorly when handed bogus + input, pointed out by Eric Wassenaar. + CONFIG: fix some more (sigh) mailertable bugs -- thanks to + Motonori Nakamura of Kyoto University (again). + +6.64/6.33 93/06/05 + Don't send 050 (-v) information after the 250 response to a QUIT + command in srvrsmtp -- clients usually close the connection + at this point, and it causes bogus error messages. + Don't send messages that have errors on input (such as unbalanced + parentheses) during SMTP transactions, since a return + message has (probably) already been sent. + Give better diagnostics on timeouts during network reads, including + information similar to the SMTP phase. + Fix bug that caused SMTP messages to deliver synchronously; this + happened after the DATA 250, and hence caused reading the + next command to be delayed. + Ignore Errors-To: header unless 'l' (lower case el) header is + specified. The Errors-To: header violates RFC 1123. + Errors-To: was only needed to take the place of the + envelope sender in the days when most Unix mailers + didn't understand about the two kinds of senders. + Don't send warning messages in response to automatically generated + messages (that is, those From:<>). + CONFIG: fix some rather stupid typos in the mailertable code + pointed out by Motonori Nakamura of Kyoto University. + CONFIG: add confUSE_ERRORS_TO configuration option. + CONFIG: if ALWAYS_ADD_DOMAIN is selected, try to use $M + (masquerade name) instead of $j. + CONFIG: don't add dots to relay names (added in 6.29); it breaks + several things, and can be simulated by dot terminating + the names of relays. For example, use: + DBbit.net.relay. + (note the trailing dot). + +6.63/6.32 93/06/01 + Fix prototypes to eliminate chars in argument lists -- some + compilers are pissy about this. + Log protocol ($r) and body type if set so we can determine if + the adaptive algorithms are working. + Pessimize on locking of database files (particularly for NEWDB + databases) during opens. There were problems with + processes opening the file while it was rebuilt; since + NEWDB caches heavily, the reader opened an empty file, + which is an error. If your system has the ability to + lock atomically on open, this works properly; otherwise, + there are race conditions. + Check mod time on .pag file instead of .dir in NDBM aliases + because the .dir file doesn't get updated for small + alias files. From John Gardiner Myers of CMU. + More Solaris portability -- it now compiles on Solaris, but + hangs up in gethostbyname(). + Move setting of RES_DEBUG flag before first myhostname() call + so we can see name server traffic on that call. + Fsync() queue files. + Fix a problem that causes -bi to try to rebuild maps other than + the alias file(s). + Fix a problem that caused udb to reject entries from any but + the first database listed. + Rearrange doc subdirectory for 4.4BSD release tape. + CONFIG: put $r into the Received line. This was an oversight. + CONFIG: fix typo (call to ruleset 99 should have been rulset 90). + CONFIG: move "auxiliary" subroutines to be in ruleset 90-99 + range -- in the long run, single digit rulesets may + become reserved for builtin use by sendmail. + CONFIG: fix major problem that causes host aliases (that is, + anything in $=w != $j) to not be recognized. This has + been around since 6.30. + +6.62/6.31 93/05/28 + BETA RELEASE + Fix recursive syserr (if there is an error printing a syserr + message). This makes the code much less eager to consider + a write error as serious. This also includes some + heuristics to be clever about closed connections. + Lock NEWDB files during gets. This requires version 1.5 or later + of the db library. If you have an older version, you + can use -DOLD_NEWDB. This will go away in a few weeks. + Fix problem causing aliases that use host maps to get overwritten. + Do appropriate byte swapping on port numbers in ident protocol + code. Fix from Allan Johannesen of WPI. + Defer opening of map files to the same time as alias files so that + the daemon will tend to pick up new versions more promptly. + Prototype a bunch more functions. + Some Solaris 2.1 changes (still doesn't link though). + Try to simplify Makefiles by including more subordinate #defines + in conf.h (based on OS type). + CONFIG: check for domains if FEATURE(mailertable) is defined. + For example, if the host name is "knecht.cs.berkeley.edu" + it will search the following mailertable keys: + knecht.cs.berkeley.edu + .cs.berkeley.edu + .berkeley.edu + .edu + This could be used to replace the special relays for bitnet + and similar nets. + +6.61/6.30 93/05/24 + Fix problem that prevented appending dots on canonified host + names. This breaks tons of config files -- very + important fix. + Fix improper pointer dereference in response to HELO command. + Fix core dump if debugging set in map_rewrite. + CONFIG: add FEATURE(always_add_domain) to always attach the + local domain (only impacts local mail). + CONFIG: try to avoid turning names into $j -- although + technically a host can only have one "canonical name", + it seems to be common practice to have several. + +6.60/6.29 93/05/22 + Major change: merge alias databases with maps. This expands and + changes the map class interface but fixes a bunch of bugs. + The important user-visible change is that the file name + in a K line now does not include the ".db" extension; this + is added automatically. Also, the -d (NIS domain) flag is + missing from the K config line; use @domain instead. + When compiling, the *_MAP names are gone -- just compile + in NDBM, NEWDB, and/or NIS support. + Announce mailer/host/user triple on -bv flag -- from Brian + Bullen of Stirling University. + Don't send more than one line in response to HELO -- it confuses + Pony Express, which then behaves very badly. However, + this change does send two line 220 greetings, with the + second line reading "ESMTP spoken here". The usersmtp + module recognizes this and goes into ESMTP mode regardless + of the setting of the "a" mailer flag. Thus, "a" means + "always try EHLO". + AIX portability changes (thanks to Christophe Wolfhugel of + Herve Schauer Consultants (Paris) for providing me with + an INSA account for this purpose). Lightly tested. Use + -D_AIX3. This probably breaks compatibility with some + older systems (e.g., 4.2bsd) but still works on SunOS + 4.1.2, Ultrix 4.2A, HP-UX 8.07, OSF/1 T1.3, and AIX 3.2.3. + Fix a problem causing an error message loop if the output channel + is hosed. + Add the Makefiles that I use for various environments -- some are + Berkeley make versions and some are old make versions. + My makefile for the NeXT box has gotten lost, alas! + PRALIASES: support for printing NEWDB databases. From + Michael J. Corrigan of U.C. San Diego. + CONFIG: don't pass pseudo-domains to $[ ... $] (if you have + a wildcard MX it can have wierd results). From + Christophe Wolfhugel. + CONFIG: dot terminate relay hostnames in S0. From Christophe + Wolfhugel. + +6.59/6.28 93/05/13 + Log version with SMTP daemon startup message. + Adjust setproctitle to work on NetBSD and BSD/386. + Fix null pointer reference in MX fallback code. + A bunch of minor fixes from Eric Wassenaar: + If deliver cannot execv the mailer, return EX_OSERR + instead of EX_TEMPFAIL (to give better + error messages). + Consistently malloc e_message. + Catch degenerate case of calling returntosender() + with an empty returnq. + MIME reformatting. + +6.58/6.28 93/05/13 + Fix bug that can cause incorrect verbose display of user smtp + messages. + Disable SMTP VERB command if PRIV_NOEXPN is set (since this + could reveal the same information. + Allow failure when reading SMTP greeting message to go on to + next MX host. + Add "MIME-Version: 1.0" header if using MIME (this was NOT + included in RFC 1344, but Bill King of Allan-Bradley + Company forwarded me email from Nathaniel Borenstein + claiming that it was an inadvertent omission). + Don't use Content-Type: X-message-header. According to John + Myers of CMU, many MIME readers will completely ignore + the data if they don't recognize it. Instead, just + add a blank line to make it a legal (empty) message. + Fix problem causing dots to keep getting appended to cached + hostnames. This can cause buffer overrun conditions. + The problem was found by Erik Forsberg of Retix, + although I used a different bug fix than he provided. + Fix parsing of split header/envelope rewriting specs -- from + Eric Forsberg. + Fix from Eric Wassenaar to correct To: lists in error messages. + +6.57/6.28 93/05/11 + Fix minor glitch causing extra ctladdrs to be output to queue + file. Just an annoyance. + Cache results of name server canonification lookups to avoid + backed up queue runs. + Major rewrite of alias.c: considerable cleanup, plus sample + (untested) support for NIS aliases. The "A" option + can now be a comma separated list (or be repeated) -- + that is, you can have multiple alias databases. Each + database can have the syntax ``class:file''; if no class + is specified, the "implicit" class is assumed. Implicit + searches through a list of compiled in types -- hash, + dbm, nis, and stab. Alias files are searched in the + order they are listed. For example: + OAhash:/etc/aliases.local,/etc/aliases + OAnis:mail.aliases@my.nis.domain + first searches the hash database /etc/aliases.local, + then the regular /etc/aliases database, then the NIS + map "mail.aliases" in the NIS domain "my.nis.domain". + If in Verbose mode (probably from VERB command) run SMTP job + in foreground and don't do RCPT optimizations. + Add udb :mailsender as equivalent to owner- for regular aliases. + Delete option 8; add option 7 that means the opposite. That is, + default to 8-bit mode; a special option is needed to + force sendmail into 7 bit mode. + Send error messages in encapsulated MIME format. + New compile flag "NIS" that turns on NIS alias and NIS map + support. + Add "j" option to send error messages in MIME (RFC 1341) + encapsulated message format per RFC 1344. The + syntax is pretty ugly if you don't have MIME-aware + user agents. + Clean up message handling (for display in mailq output). + New setproctitle implementation for 4.4bsd. + Create files (such as ~/dead.letter) using mode FileMode (the + F option value) instead of 0666. + Fix bug causing output of EXPN command to not be fully qualified. + This may cause some problems with UUCP addresses that + will require some config file assistance -- specifically, + the $: part has to include the host name for this output + to make sense. + Fix a problem that sometimes diagnosed errors and still sent the + message if the header syntax was bad. + Fix a bug that caused an error message to be emailed when sendmail + was operating in -bv mode. + Add "ListenQueueSize" keyword to daemon options option (OO) to + set the queue size parameter passed to listen(). You + will normally have to tweak your kernel to up this. + Strip spaces off of beginning of message-id before logging (in + case it was folded across lines). + Tweak compile flags in daemon.c -- there were some cases where + it wouldn't work without NETINET. + Change *file* mailer to output all the usual default headers + (From, Date, Message-Id). It gets used when sending + back error messages. + CONFIG: explicitly catch and diagnose list:; syntax in ruleset + zero -- this is not a valid recipient syntax according + to RFC 821. + CONFIG: add confMIME_FORMAT_ERRORS to send error messages in + MIME format. Defaults to on. + CONFIG: add SMTP_MAILER_FLAGS and UUCP_MAILER_FLAGS to augment + the flags for those mailers. + +6.56/6.27 93/05/01 + Fix problem that causes the fallback mail to postmaster + (case ESM_POSTMASTER in savemail()) to not look at + aliases (ugh). + Some more HPUX tweaking (compile flag hpux => __hpux so it + still works in ANSI mode). + Don't try to flock non-regular files when mailing to a file. + In particular, this was a problem if you tried to + send to /dev/null. + Fix a wierd bug that can cause senders to be queued as + recipients if the name server is down when the mail + is initially sent. This hack just ignores sender + deletion (essentially, it sets the MeToo flag) if there + is a TEMPFAIL during processing of the sender address. + Obscure. + Fix a dangling else problem -- from Brian Bullen from University + of Stirling, UK. + Add the "b" mailer flag to force a blank line on the end of + messages. Some brilliant versions of /bin/mail insist + on this but do not add it themselves. + Add the "g" mailer flag to prevent user SMTP from sending + "MAIL From:<>". This is only intended to be a + transitional gesture, and should not be used if at + all possible. It appears that Berkeley and IDA + config files have always handled this properly; the + UK config kit apparently does not. + Don't lowercase and then capitalize header field names -- leave + them with original capitalization. Fixes from Bill + King of Allen-Bradley Company. + Further cleanup and improved reporting of error messages, + particularly conditions that cause messages to be + requeued for future delivery. + Tweak syslog priorities in some cases. + CONFIG: clean up route-addr on UUCP addresses. + +6.55/6.25 93/04/27 + HPUX 8.07 compatibility changes in getla() -- I had to make + these changes to get it to work at Berkeley, although + others seem to have been working before (???). + Various patches to XLA code. + Fix problem that causes setuid bit on files to be ignored from + SMTP or in queue runs. Problem noted by Jason Ornstein + of Under The Wire, Inc. + Fix problem that can cause CNAMEs to be ignored. + Generalize getmxrr to match local host in $=w instead of a + single name passed in. + Some cleanup from Eric Wassenaar: + Use FileMailer instead of ProgMailer in two places. + Eliminate duplicate 8th-bit stripping in commaize. + Fix a problem with mis-parsing of backslash escapes + under some circumstances. + NIS map fix (was always including trailing null character) + from Mike Glendinning of Ingres UK. + Add "a" mailer flag to try using ESMTP. It tries the EHLO + command and if that fails falls back to regular SMTP. + Also parses EHLO option keywords. If host supports + SIZE extension, this is added to the MAIL FROM: + command. + Extend "b" option to include a second value which is the + maximum message size this server is willing to accept. + For example, a value of "10/1000000" says that there + must be ten blocks free, and sendmail will reject + any message larger than one megabyte. + Some portability hooks for NeXT (this could be applicable + to Mach in general). You have to create an empty + file called "unistd.h" to get it to compile. + Adjust config values (MAXLINE, MAXATOM, and PSBUFSIZE) to + be more generous. + Add X400-Received: to the list of headers tagged with H_TRACE + in conf.c. From Bill King, Allen-Bradley Co. + +6.54/6.25 93/04/19 + Fix problem that caused redefinition of SMTP and QUEUE compile + flags. Pointed out by Jon Forrest of the Sequoia 2000 + project at Berkeley. + Properly handle \! hack -- it was treating host\!user as one + token (host!user) instead of three (host, !, user). + Fix from Eric Wassenaar of NIKHEF-H. + Fix compilation problem in getauthinfo() if IDENTPROTO is off. + Turn off DEFNAMES and DNSRCH when getting the hostsignature + (i.e., MX records) in level 1 configuration files; this + matches the old behaviour. From Motonori Nakamura of + Kyoto University. + Improve error message printing -- if sent through an alias, + error messages include the name of the alias in the + message. Unfortunately, in order to make this work + properly in queue runs, this changes the format of the + C line in the qf file. The relatively uselessness of + the previous information was pointed out to me by + Allan E Johannesen of WPI. + Add XLA compile flag to add hooks to Christophe Wolfhugel's + extended load average code. This is still in very early + form. For information regarding the guts of the xla + code, contact Christophe.Wolfhugel@grasp.insa-lyon.fr. + Additional hooks for detecting tempfails in rewriting rules + (that is, in map lookups). + +6.53/6.25 93/04/15 + Properly diagnose ruleset zero returning null (instead of a mailer + triple). From Motonori Nakamura of Kyoto University. + More generalization of socket code for other protocols. + Shorten timeouts on reverse name lookups -- since they are done + during connection establishment, long timeouts here can + cause higher level timeouts. This mainly serves to accept + mail from hosts that do not have proper reverse (PTR) DNS + records set up. + Reset e_statmsg before each mailer invocation to avoid bogus + messages in the log. + Redefine $r, $s, and $_ in error envelopes so you don't get + incorrect cruft in the error message. Problem noted by + Motonori Nakamura of Kyoto University. + Fix a problem that can cause failure to return errors to Postmaster + in certain cases. From Motonori Nakamura. + Fix a problem that can cause some systems to give duplicate error + messages when a bad syntax address such as "<a" is presented + to an SMTP server. It doesn't seem to occur on all + machines. From Motonori Nakamura. + Default IDENTPROTO off for Ultrix and HPUX, which apparently have + the interesting "feature" that when they receive a "Host + unreachable" message they closes all open connections to + that host. However, some firewall gateways send this message + if you try to connect to an unauthorized port, such as the + IDENT port (113). Thus, no email can be received from such + hosts. There is some evidence that versions of Ultrix before + 4.3 do not have this problem. Thanks to Tom Ivar Helbekkmo + for pointing out this behaviour to me and to Michael Corrigan + of U.C. San Diego for informing me about the HPUX problem. + Allow IPC mailers to return a colon-separated list of hosts in the + $@ clause; these are searched in order as though they were + MX records. + When sending an error report, print the list of addresses tagged + as bad. Requested by Allan E Johannesen of WPI. + Change map function calls to return a status code. This gets + passed back as the result of rewrite. Parseaddr marks + the address as a QUEUEUP address if the return code is + EX_TEMPFAIL. All this to queue properly if the name + server is down. This code is not well tested. This code + changes the interface to map lookup functions (a fifth + parameter, int *statp, is added). Feature requested by + Dan Oscarsson. + Don't delete quotes (in the dequote map) if there are spaces in + the string, since this would cause them to be replaced by + the SpaceSub character. + Accept BODY=8BITMIME on SMTP MAIL command. This isn't advertised + because the 8BIT to 7BIT translation doesn't exist yet. + This does add a "bodytype" field to both envelope and + queue file and a -B command line flag to pass the type in + during direct invocations. + Discard return error messages only on responses to responses to + responses, not on responses to responses. That is, the + algorithm is to try return to sender, then return to + postmaster, then discard. Previously it discarded + immediately if the return to sender pass failed. + CONFIG: back out change to hide unqualified hostnames behind %-hack. + This screws up local aliases and .forward files. + CONFIG: add FEATURE(nocanonify) to turn off calls to $[ ... $]; + some sites only handle completely canonified names. + Requested by John Gardiner Myers of CMU. + CONFIG: some UUCP code was still included even if FEATURE(nouucp) + was specified. + +6.52/6.24 93/04/10 + Clean up some minor glitches on error return messages pointed out + by Motonori Nakamura of Kyoto University. + Fix reply() to not reset SmtpReplyBuffer on fatal errors; this + was supposed to reset SmtpMsg Buffer. This makes the + client side code virtually useless. Reported by Allan + E Johannesen of WPI and Phil Brandenberger of Swarthmore. + Better debug messages if fuzzy is disabled, suggested by Allan + E Johannesen of WPI. + Offset SmtpReplyBuffer by four in usersmtp when checking for + loopback. From Eric Wassenaar. + Don't set $s until after runinchild in srvrsmtp -- otherwise + it gets cleared. From Eric Wassenaar. + Implement IDA-style $&x for deferred macro expansion. + More POSIX compatibility. + CONFIG: Hide unqualified hostnames behind %-hack using $s as the + actual sender. This is only done if $r is non-null, that + is, if this is not locally submitted mail. + CONFIG: Add FEATURE(bitdomain) allowing mapping of BITNET host + names to internet domains. A program contributed by + John Gardiner Myers of CMU to create the maps is included + in the contrib directory (in the "misc" tar file). + CONFIG: Add FEATURE(uucpdomain) for a similar mapping for UUCP + hosts. There is currently no tool to create this map. + +6.51/6.23 93/04/04 + Add D= mailer flag to specify a path of possible working directories + in which to execute the mailer. This is intended for the + prog mailer; some shells can get upset if they don't have + access to the current directory. + Add RFC 1413 (IDENT) protocol support. This is only very loosely + tested. This adds a $_ macro to be the authenticated + info (in ``user@domain [address]'' form) and debug flag + 9 to trace the protocol. + Check for loopbacks in usersmtp instead of srvrsmtp -- there is no + reason for a local agent to not be talking to the localhost + (although the inverse is not true). + Add a few hooks for automated map rebuilding.

San Diego. + Don't ignore rest of queue if any job is not runnable. This can + also cause an incorrect job to be lost. Fix from + Eric Wassenaar. + Always respond "quickly" to RCPT command; do alias expansion and + the like later. This also means that mail for lists that + have errors will be acccepted, and an error sent back + later. This is done by instantiating the queue file + and then immediately running and requeueing it. + +6.48/6.22 93/03/30 + Fix incorrect diagnosis of infinite loop in ruleset.

Fix from Takahiro Kanbe of Fuji Xerox + Information Systems Co., Ltd. + Change default for PrivacyFlags in conf.c to 0 -- since it always + "or"s in new values, there was no way to turn off the + AuthWarning stuff. + Add O option to set SMTP daemon options. + Add V option to set fallback MX host. This always sorts at lower + priority than anything it gets from the name server. It + should only be used for environments with very bad network + connectivity.

Fix from Michael Corrigan + of U.C. San Diego. + Fall back to other MX records if there is an error anywhere + in delivery (actually on MAIL or DATA -- RCPT is harder). + Suggested by John Gardiner Myers and Motonori Nakamura. + Revert to non-prototypes -- it turns out that our ANSI C + compiler is more forgiving than most others about + mixing prototyped extern declarations with non-prototyped + function definitions. + Fix a problem with multi-word class matching pointed out by + Neil Rickert. Given: + CX b a.b.c + R$+ $=X $+ $: $1 < $2 > $3 + the input "user@a.b.c" failed instead of being properly + rewritten as "user@a.<b>.c". + Neil also convinced me that it was correct that $~ should match + only one token -- the problem is that it's always possible + to add another token, so $~ matches far too eagerly. + +6.45/6.21 93/03/25 + Implement multi-word classes (properly!). + +6.44/6.21 93/03/25 + Add X-Authentication-Warning: headers to clue users into possible + attempts to forge mail. This is on the authwarnings + privacy flag, but is the default. Suggested by Bryan + Costales of ICSI. + Pass default units for convtime in so they can be more reasonable. + Allow config files to always add a new Comments: header (i.e., + they will be added even if an old one already exists). + Suggested by Bryan Costales of ICSI. + Allow config files to delete an existing Return-Path: header. + These should only be added at final delivery. Suggested + by Bryan Costales of ICSI. + Some debugging additions. Suggested by Bryan Costales of ICSI. + Clean up logging of Family 0 addresses. Noted by David Muir + Sharnoff and others. + Add a "dequote" map class. This allows config files to strip + quotes off of addresses. Note that this is not a builtin + map, just a class -- so you have to define the map + using the K line. + Fix a bug in the queueup() loop getting a locked tf where in + very odd cases it can fall off the bottom and core dump. + Of course, it was P{r Emanuelsson who found it.... + Open a new transcript when splitting an envelope. Problem found + by Allan E Johannesen of WPI. + Improved error output in endmailer if the mailer core dumps. + CONFIG: Fix typo in UUCP mailer definition. + CONFIG: Default several of the new options on: eight bit input, + privacy flags set to "authwarnings", and message warning + set to 4h. + CONFIG: Use dequote map. + +6.43/6.20 93/03/23 + Fix problem with assumption of an sa_len field in a generic + sockaddr -- it turns out that most vendors haven't + picked up this (very important) fix. + Change compilation flags for daemon code -- select one or both + of NETINET or NETISO, but don't ever set DAEMON manually. + CONFIG: add FEATURE(mailertable) to do IDA-style mailertables. + +6.42/6.19 93/03/19 + Use Postmaster as default fallback return address, not root. + POSIX changes for file descriptor handling. + Diagnose errors writing new queue file. + If you change the owner using an owner- alias, also change the + error mode to EM_MAIL so that errors don't get dropped + into an inappropriate directory. Problem noted by + Allan E Johannesen of WPI. + If you are su'ed to root, send email as who you really are, not + as root. From Brian Kantor of U.C. San Diego. + Allow warning messages to be sent after a configurable interval + has passed without delivery. The message is sent only + once per envelope. This changes the format of the qf + file to have an F line, and the format of the T option + to accept take the format "return/warn" (both intervals). + Don't force all local names to lower case -- this was left over + from the wierd handling of case mapping on aliases. It + is now driven (as expected) by the "u" mailer flag. + Problem noted by P{r Emanuelsson. + Fix problem that caused headers on returned email to be trashed; + they were getting freed, but are still accessible via + BlankEnvelope. + Fix problem that caused bogus ids to be created on returned + mail. + Add support for ISO and other non-INET networking. This is by + no means finished yet. This does assume a lot of other + system support, like a version of gethostbyname that + returns non-AF_INET addresses. + CONFIG: change default on prog mailer to keep upper case in + user names (i.e., in the program command line). + CONFIG: strip trailing dots off of hosts in uucp mailer before + convert to bang format. + CONFIG: create new "relay" mailer for $R (LOCAL_RELAY) and $H + (MAIL_HUB) delivery that doesn't add local domain. Note + that this violates 821, but is probably "more correct" + for what we are trying to do. Problem pointed out by + Michael Graff of Iowa State. + +6.41/6.18 93/03/18 + Clean up unnecessary creates of queue ids (i.e., empty qf files) + when not needed, such as when starting up an SMTP + connection. + Fix problem where split envelopes aren't instantiated in the queue. + This is quite a serious bug. + Owner- aliases had problems with leading spaces causing a + premature delimitation. + +6.40/6.18 93/03/18 + Have ending 250 (after DATA) include the id; suggested by + Brian Kantor of UC San Diego. + Add logging on envelope splitting. + Change queue ids to have one more letter encoding the hour of + the day so that during a single day there is a greater + likelihood of uniqueness; requested by Brian Kantor. + +6.39/6.18 93/03/18 + Fix minor compile problem if LOCKF is defined. + Define size of tobuf in conf.h. Observed by Toshinari Takahashi + of Toshiba. + Restore e_sender -- this is equivalent to e_from.q_paddr without + decorations such as angle brackets and comments. + OSF/1 on Alpha changes from Allan E Johannesen of WPI. + CONFIG: fix typo in S3 for list syntax (;: => :;). Thanks to + Christopher Hoover for noting the problem. + +6.38/6.17 93/03/17 + Pass envelope to disconnect to avoid another use of CurEnv, which + can apparently end up being null at inopportune times. + Log "received from" as "relay=" for consistency (suggested by + John Gardiner Myers). + Fix major bug in header handling: if no From: line existed in + the header (so sendmail inserts one), and the sender is + an alias that has an owner, the From: line shows the + owner (as well as the envelope). Fixed by early binding + the headers (which will change debugging output). + HPUX portability patches from Michael J. Corrigan of UC San Diego. + Some attempts to adapt better to out of open file conditions. + Some changes to ctladdr handling in queue files. + +6.37/6.17 93/03/16 + MAJOR CHANGE: delete e_sender and e_returnpath (why are these + different from e_from?) and $< macro. + Log correct IP address in relay= field even if the connection + times out. + Log "received from [RESPONSE]" on EF_RESPONSE messages (from + John Gardiner Myers). + Fixes to SysExMsg logging (sometimes just got "message: %s" + instead of "message: error message"), noted by Eric + Wassenaar. Also reported by Motonori Nakamura. + Improvements to MX piggybacking code, from Motonori Nakamura. + Fix case where CurHostName points to an auto variable that has + been deallocated (from Motonori Nakamura). + Fix bug causing newlines to be included in aliases if option + "n" (check alias RHS) is set; bug noted by David Muir + Sharnoff. + Fix problem causing user names that should be mapped to lower + case to not be mapped if they are sent during a queue + run. This greatly simplifies the case mapping code. + Problem noted by Allan E Johannesen of WPI. + Don't do recipient address rewriting in buildaddr. This + improperly did recipient rewriting on sender addresses, + and just seems bogus in general -- but the change could + break some .cf files. + Pass TZ envariable to child processes for System V. + CONFIG: allow LOCAL_RULE_1 and LOCAL_RULE_2 if you want to + define those rulesets. + KNOWN PROBLEM: I have seen some problems on SunOS that causes + the User Data Base to give errors on some addresses. I + have tracked the problem back at least as far as 93.02.15 + (version 6.22). Running with debugging on makes it + go away, so I conclude that it is referencing uninitialized + stack data. I haven't been able to track this down yet. + +6.36/6.16 93/03/08 + Allow local mailer to specify $@host -- this lets you assign the + "foo" part of jgm+foo to $h for passing in to the local + mailer. + Additional debug printing in getcanonname (show query type). + Don't add the e_fromdomain on sender addresses -- this interacts + wierdly with the owner- code. + Improve delivery logging to not log obvious or meaningless stuff. + Include numeric IP address in Received: lines per RFC 1123 section + 5.2.8. + Fixed a bug in checking stat() return value if restrictmailq is + set. Also, check the entire group set instead of just the + primary group. Both from John Gardiner Myers. + Don't have usrerr automatically print errno, since this is often + misleading. + Use transienterror() in makeconnection after connect() fails and + in openmailer after execve() fails (from Eric Wassenaar). + Also moved transienterror() from util.c to conf.c. + Clean up from= logging on response messages. + Undo patch allowing prescan to return a null vector -- it breaks + too many things. + Config: FEATURE(notsticky) lets you use UDB for everything coming + in to the machine, even if it is specifically targetted + to this machine. Without it, UDB is bypassed if the user + name is fully qualified. + Config: fix another minor botch with <> (local mailer wasn't + mapping them properly). + +6.35/6.15 93/03/05 + Fix getrealhostname to return null if sinlen <= 0 -- this can + occur if stdin is a pipe. + Avoid infinite loop in getcanonname if name server return + NO_DATA (for example). + Config: avoid having C flag qualify list syntax and error syntax. + +6.34/6.14 93/03/05 + Fix logging in deliver to not pass too many parameters to Ultrix + versions of syslog. + Don't write the pid file until after the daemon has actually + opened and conditioned the connection. + Consider addresses "different" if their q_uids differ (so that + two users forwarding to the same program will be seen + as different, rather than the same). + Fix problem with bad parameters in main() -- they set ExitStat + but don't exit. + Fix null pointer references through RealHostName -- painfully + discovered by Allan E Johannesen of WPI. + Fix bug causing user@@localhost to core dump (yuch). + Config: don't put two @host.dom.ain on users in $=E in SMTP + mailer. Also, catch user@ (no host) in ruleset 0. + +6.33/6.13 93/03/03 + Config: add confCW_FILE as the name of the cw configuration file + (defaults to /etc/sendmail.cw). From P{r Emanuelsson. + Allow prescan to return a pointer to an empty list -- this is + not an error. Also, clean up error reporting to avoid + double errors (prescan reports once, then the caller + reports again). + Changes to avoid trusting T_ANY queries -- run them, but if you + don't get the info you expected, do T_A and T_MX queries + anyhow. This also fixes an oversight where _res.options + bits were being ignored. + If PRIV_NOVRFY is set, use 252 response code instead of 502 per + RFC 1123 section 5.2.3. It's not 100% clear that this + is correct, but it probably works better with stupid + mailers that do a VRFY and only check the first digit. + +6.32/6.12 93/03/02 + Fix uninitialized variable "protocol" in smtp code. + Include <unistd.h> in sendmail.h -- move towards POSIX/ANSI. + Additional hooks for RFC 1427 (ESMTP SIZE extension). This + includes requiring that enoughspace() know the system + block size, which will undoubtedly break most ports. + Trace flag 19 in use for srvrsmtp.c. + Additional logging -- notably the sending mailer name. This + also changes the delivery logging to strict field=value + syntax. + Fix some problems with messages getting sent even to addresses + that had been marked bad -- from Eric Wassenaar. + More WIDE changes: accept host name inside [...] as non-MXed + host. This is intended ONLY for use inside firewalled + environments, where the MX points at the gateway. + Change .cf file conventions so that mapping for <> addresses + don't have an @ in them (to avoid confusing the C mailer + flag). Pointed out by Neil Rickert. + Config extensions for Sam Leffler's FlexFAX software. + +6.31/6.10 93/02/28 + Fix some more bugs in alias owner code -- there were some wierd + cases where an error in a non-aliased name would override + the return info in an aliased name with an owner. + Changes from WIDE Project, forwarded to me by Motonori Nakamura: + Log actual delivery host (after MX et al); from + yasuhiro@dcl.co.jp. + Log daemon startup. + Deliver Postmaster copies without a body. + Better logging of SMTP senders. + Send all program email as daemon even when local. + As requested in various forms from many people, accept -qIstring + to limit queue runs to jobs with queue-id matching string. + Similarly for -qRstring for recipients, -qSstring for + senders. + Initial hooks for ESMTP support (see RFC 1425). + Fixed a syntax error in the UUCP mailer specification that caused + core dumps on startup. + Check for missing A= or P= arguments in mailer definitions. + +6.30/6.10 93/02/27 + Require FROZENCONFIG compilation flag to include frozen + configuration code. Frozen configuration is really + not a very good idea any more, particularly in shared + library environments. + Do better checking of errno after opens of :include: and .forward + files to defer delivery on network and other transient + errors. Suggestion from Craig Everhart. + Fix minor botch in read timeout macro processing. + Add FEATURE(nouucp) to config files for sites that know absolutely + nothing about UUCP. + Add built cf files to distribution tape and clarify how to build + them if you don't have the Berkeley make. + Some sizeof(long) portability changes for the Alpha, from Allan + E Johannesen. + Add "restrictmailq" privacy flag -- if set, only people in the same + group as your queue directory can print the queue. If you + set this, be sure you also restrict access to log files.... + Fix another bug in owner-list stuff that can cause data files to + be "lost". + Fix a bug with queue runs that cause forwards to yourself to go + into alias/forwarding loops. I'm still iffy about this + fix. + Fix from Eric Wassenaar for suppression of return message code. + +6.29/6.9 93/02/24 + Fix yet another problem in alias owner code -- put the wrong return + address on the enclosed return-to-sender letter. + +6.28/6.9 93/02/24 + Fix botch in alias owner code that caused it to not operate if the + error was detected locally. + +6.27/6.9 93/02/24 + M_LOCAL => M_LOCALMAILER to avoid conflict with Ultrix include + file <sys/mount.h>. + Miscellaneous bug fixes from Eric Wassenaar: + sendmail -bv -t logs the from line even though in verify + mode only. + sendmail -v can go into queue mode if shouldqueue returns + TRUE. + Add route-addr pruning per RFC 1123 section 5.3.3. This can be + disabled using the "R" option. + Delete (always undocumented) -R flag (save original recipients); + there are ways to syslog(3) these now. + Clean up SMTP reply codes -- specify them as needed in the code, + instead of in conf.c -- this was needed during the NCP to + TCP transition, but seems silly now. This also changes + parameters to message and nmessage. + Have mailstats read the .cf file to find the sendmail.st file and + get text versions of mailer names. An initial version of + this code was provided by Tuominen Keijo (although the + comments indicate the good bits were written by "E.V."). + Add yet more System V compatibility hacks. + Fix bug in VRFY code (assumes everything must be a local user). + Allow specification of any of the hard-wired pathnames in the + Makefile. + Delete concept of "trusted users" -- this really didn't provide + any security anyway, and caused some problems. + Delete last vestige of support for the word "at" as an equivalent + to the character "@". + Propagate owner-foo alias information into the envelope sender. + Based on code from John Gardiner Myers. This is a major + semantic change -- beware! + Allow $@ on LHS to indicate "match zero" -- this is used to match + the null expression. + +6.26/6.8 93/02/21 + Don't "lose" queue runs. Very important fix from (who else?) + Eric Wassenaar. + Completely reset state on RSET command -- from Eric Wassenaar. + Send error messages and return receipts using an envelope sender + of <> regardless of the setting of $n. Rewriting rules + can undo this if they feel the necessity, as might be + needed for networks that don't understand the syntax. + This is permitted by RFC 821 section 3.6 and required by + RFC 1123 section 5.3.3. THIS REQUIRES VERSION 4 CONFIG + FILES because the rulesets must be able to parse <> + properly. + Don't ever send error messages to "<>" -- they will get sent to + the local postmaster or dumped in /usr/tmp/dead.letter + instead. Per RFC 1123 section 5.3.3. + Explicitly check for email to yourself as a dotted quad. You + have to call $[ [ ... ] $] to get this. + Up the message timeout to five days per RFC 1123 section 5.3.1.1. + Make all read timeouts individually configurable, as strongly + recommended by RFC 1123 section 5.3.2. + Use f_bavail (blocks available to regular users) instead of f_bfree + (blocks available to superuser) in free block checks. + Change $d macro to be the current time, not the origination time, + since this is consistent with how it is used now. + Generalization of enoughspace from Eric Wassenaar covering + SGI, Apollo, HPUX, Ultrix, and SunOS. + Ignore process group signals -- some front ends can do this if + you kill a window too quickly. From Eric Wassenaar. + Change umask to 022. + +6.25/6.8 93/02/20 + Close all cached connections before calling mailers and after + forking for delivery (caused double closes which resulted + in false errors). + Add FEATURE(redirect) in config files -- this allows you to alias + old addresses to a pointer to the new address that will + give a 551 error message, but not deliver the mail. + Some code changes to make the 551 errors look pretty. + Names of M4 program paths in config files have changed -- they + are all XXX_MAILER_PATH now, to match XXX_MAILER_FLAGS. + Fix a bug in the QSELFREF code having to do with empty .forward + files, reported by Eric Wassenaar. + Add option "p" (privacy flags); this allows you to tune how + picky the SMTP server will be. This also adds the + confPRIVACY_FLAGS M4 macro in the config files. + Add option "b" (minimum blocks free). If there are fewer than + this number of blocks free on the filesystem containing + the queue directory, the SMTP MAIL command will return + a 452 response and ask you to try again later. This + also adds the confMIN_FREE_BLOCKS M4 macro in the config + files. + Made VRFY just verify (doesn't expand aliases and .forward files); + EXPN does full expansion. RCPT in queue-only mode also + doesn't chase aliases and .forward. + +6.24/6.7 93/02/19 + Increase the number of domain search entries in domain.c to allow + for the extra "" entry indicating the root domain. + Reported by Motonori Nakamura of Kyoto U. + Add a "SMART_HOST" in the configs for UUCP-connected sites that + want to forward all mail with extra "@"s to that site. + Also allows SMART_HOST, LOCAL_RELAY, and MAIL_HUB to + be specified as ``mailer:hostname'' to use an alternate + mailer. + Clarified and updated some wording in the Operations Guide. + Add the "c" mailer flag -- this suppresses all comment parts of + addresses (requested by John Curran of NEARnet). + Have -v print prompts in -bt mode even if stdin is not a terminal + (default behaviour is to be silent if not reading from + a terminal). Suggested by Bryan Costales, ICSI. + Move the metacharacters from C0 space (\001-\037) into C1 space + (\201-\237). This also fixes a bunch of potential bugs + with G1 characters (\240-\276) in headers relating to + negative numbers passed to isspace() et al. + Add YP_LAST_MODIFIED and YP_MASTER_NAME to DBM version of alias + database if YPCOMPAT is #defined. Enhancement from + Takahiro Kanbe of Fuji Xerox Information Systems Co., Ltd. + Add "list" Precedence (-30); this can be used with old sendmails + which will map to precedence 0 (which will return error + messages). Suggested by Stephen R. van den Berg. + Many bug fixes from Eric Wassenaar of the National Institute for + Nuclear and High-Energy Physics, Amsterdam: + Clear timeouts properly on open failures in include(). + Don't dereference through NULL if no home directory found. + Re-establish SIGCHLD signal on System 5 in reapchild(). + Avoid NULL pointer reference on -pFOO flag. + Properly handle backslash escapes in comments. + Correctly check reply status on SMTP NOOP command. + Properly save SMTP error message if peer gives + "Service Shutting Down" message. + Avoid writing to the transcript if it couldn't be opened. + Signal errors in SMTP children to parent properly. + Handle self references in a list more globally (include a + QSELFREF bit in the address flags). This enhancement + was suggested by Eric Wassenaar. + Use initgroups() in hpux, even though it's System-V based.

These use features in the new (R8) sendmail; they will +not work on other versions. + +These configuration files are probably not as general as previous +versions, and don't handle as many of the weird cases automagically. +I was able to simplify by them for two reasons. First, the network +has become more consistent -- for example, at this point, everyone +on the internet is supposed to be running a name server, so hacks to +handle NIC-registered hosts can go away. Second, I assumed that a +subdomain would be running SMTP internally -- UUCP is presumed to be +a long-haul protocol. I realize that this is not universal, but it +does describe the vast majority of sites with which I am familiar, +including those outside the US. + +Of course, the downside of this is that if you do live in a weird +world, things are going to get weirder for you. I'm sorry about that, +but at the time we at Berkeley had a problem, and it seemed like the +right thing to do. + +This package requires a post-V7 version of m4; if you are running the +4.2bsd, SysV.2, or 7th Edition version, I suggest finding a friend with +a newer version. You can m4-expand on their system, then run locally. +SunOS's /usr/5bin/m4 or BSD-Net/2's m4 both work. GNU m4 version 1.1 +also works. Unfortunately, I'm told that the M4 on BSDI 1.0 doesn't +work -- you'll have to use a Net/2 or GNU version. + +IF YOU DON'T HAVE A BERKELEY MAKE, don't despair! Just run +"m4 ../m4/cf.m4 foo.mc > foo.cf" -- that should be all you need. +There is also a fairly crude (but functional) Makefile.dist that works +on the old version of make. + +To get started, you may want to look at tcpproto.mc (for TCP-only +sites), uucpproto.mc (for UUCP-only sites), and clientproto.mc (for +clusters of clients using a single mail host). Others are versions +that we use at Berkeley, although not all are in current use. For +example, ucbarpa has gone away, but I've left ucbarpa.mc in because +it demonstrates some interesting techniques. + +I'm not pretending that this README describes everything that these +configuration files can do; clever people can probably tweak them +to great effect. But it should get you started. + +******************************************************************* +*** BE SURE YOU CUSTOMIZE THESE FILES! They have some *** +*** Berkeley-specific assumptions built in, such as the name *** +*** of our UUCP-relay. You'll want to create your own domain *** +*** description, and use that in place of domain/Berkeley.m4. *** +******************************************************************* + + ++--------------------------+ +| INTRODUCTION AND EXAMPLE | ++--------------------------+ + +Configuration files are contained in the subdirectory "cf", with a +suffix ".mc". They must be run through "m4" to produce a ".cf" file. +You must pre-load "cf.m4": + + m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf + +where ${CFDIR} is the root of the cf directory and config.mc is the +name of your configuration file. If you are running a version of M4 +that understands the __file__ builtin (versions of GNU m4 >= 0.75 do +this, but the versions distributed with 4.4BSD and derivatives do not) +or the -I flag (ditto), then ${CFDIR} can be in an arbitrary directory. +For "traditional" versions, ${CFDIR} ***MUST*** be "..", or you MUST +use -D_CF_DIR_=/path/to/cf/dir/ -- note the trailing slash!

It is provided on the sendmail + # distribution as a sample only. To create your own configuration + # file, create an appropriate domain file in ../domain, change the + # `DOMAIN' macro below to reference that file, and copy the result + # to a name of your own choosing. + # + divert(0) + +The divert(-1) will delete the crud in the resulting output file. +The copyright notice can be replace by whatever your lawyers require; +our lawyers require the one that I've included in my files. A copyleft +is a copyright by another name. The divert(0) restores regular output. + + VERSIONID(`<SCCS or RCS version id>') + +VERSIONID is a macro that stuffs the version information into the +resulting file. We use SCCS; you could use RCS, something else, or +omit it completely. This is not the same as the version id included +in SMTP greeting messages -- this is defined in m4/version.m4. + + OSTYPE(hpux9)dnl + +You must specify an OSTYPE to properly configure things such as the +pathname of the help and status files, the flags needed for the local +mailer, and other important things. If you omit it, you will get an +error when you try to build the configuration. Look at the ostype +directory for the list of known operating system types. + + DOMAIN(CS.Berkeley.EDU)dnl + +This example is specific to the Computer Science Division at Berkeley. +You can use "DOMAIN(generic)" to get a sufficiently bland definition +that may well work for you, or you can create a customized domain +definition appropriate for your environment. + + MAILER(local) + MAILER(smtp) + +These describe the mailers used at the default CS site site. The +local mailer is always included automatically. Beware MAILER +declarations should always be last in the configuration file, and +MAILER(smtp) should always precede MAILER(uucp). + +One word of warning: M4 macros are expanded even in lines that appear +to be comments. For example, if you have + + # See FEATURE(foo) above + +it will not do what you expect, because the FEATURE(foo) will be +expanded. This also applies to + + # And then define the $X macro to be the return address + +because ``define'' is an M4 keyword. If you want to use them, surround +them with directed quotes, `like this'. + + ++--------+ +| OSTYPE | ++--------+ + +You MUST define an operating system environment, or the configuration +file build will puke. There are several environments available; look +at the "ostype" directory for the current list. This macro changes +things like the location of the alias file and queue directory. Some +of these files are identical to one another. + +It is IMPERATIVE that the OSTYPE occur before any MAILER definitions. +In general, the OSTYPE macro should go immediately after any version +information, and MAILER definitions should always go last. + +Operating system definitions are usually easy to write. They may define +the following variables (everything defaults, so an ostype file may be +empty). Unfortunately, the list of configuration-supported systems is +not as broad as the list of source-supported systems, since many of +the source contributors do not include corresponding ostype files. + +ALIAS_FILE [/etc/aliases] The location of the text version + of the alias file(s). It can be a comma-separated + list of names (but be sure you quote values with + commas in them -- for example, use + define(`ALIAS_FILE', `a,b') + to get "a" and "b" both listed as alias files; + otherwise the define() primitive only sees "a"). +HELP_FILE [/usr/lib/sendmail.hf] The name of the file + containing information printed in response to + the SMTP HELP command. +QUEUE_DIR [/var/spool/mqueue] The directory containing + queue files. +STATUS_FILE [/etc/sendmail.st] The file containing status + information. +LOCAL_MAILER_PATH [/bin/mail] The program used to deliver local mail. +LOCAL_MAILER_FLAGS [rmn] The flags used by the local mailer.

Default + flags are `DFMhuU' (and `m' for uucp-new mailer, + minus `U' for uucp-dom mailer). +UUCP_MAILER_ARGS [uux - -r -z -a$g -gC $h!rmail ($u)] The arguments + passed to the UUCP mailer. +UUCP_MAILER_MAX [100000] The maximum size message accepted for + transmission by the UUCP mailers. +UUCP_MAILER_CHARSET [undefined] If defined, messages containing 8-bit data + that ARRIVE from an address that resolves to one of + the UUCP mailers and which are converted to MIME will + be labelled with this character set. +FAX_MAILER_PATH [/usr/local/lib/fax/mailfax] The program used to + submit FAX messages. +FAX_MAILER_MAX [100000] The maximum size message accepted for + transmission by FAX. +POP_MAILER_PATH [/usr/lib/mh/spop] The pathname of the POP mailer. +POP_MAILER_FLAGS [Penu] Flags added to POP mailer.

Flags + ``DFMmn'' are always set. +PROCMAIL_MAILER_ARGS [procmail -m $h $f $u] The arguments passed to + the Procmail mailer. +PROCMAIL_MAILER_MAX [undefined] If set, the maximum size message that + will be accepted by the procmail mailer. +MAIL11_MAILER_PATH [/usr/etc/mail11] The path to the mail11 mailer. +MAIL11_MAILER_FLAGS [nsFx] Flags for the mail11 mailer. +MAIL11_MAILER_ARGS [mail11 $g $x $h $u] Arguments passed to the mail11 + mailer. +PH_MAILER_PATH [/usr/local/etc/phquery] The path to the phquery + program. +PH_MAILER_FLAGS [ehmu] Flags for the phquery mailer. +PH_MAILER_ARGS [phquery -- $u] -- arguments to the phquery mailer. +CYRUS_MAILER_FLAGS [A5@] The flags used by the cyrus mailer. The + flags lsDFMnP are always included. +CYRUS_MAILER_PATH [/usr/cyrus/bin/deliver] The progam used to deliver + cyrus mail. +CYRUS_MAILER_ARGS [deliver -e -m $h -- $u] The arguments passed + to deliver cyrus mail. +CYRUS_BB_MAILER_FLAGS [undefined] The flags used by the cyrusbb + mailer. The flags lsDFMnP are always included. +CYRUS_BB_MAILER_ARGS [deliver -e -m $u] The arguments passed + to deliver cyrusbb mail. + + + ++---------+ +| DOMAINS | ++---------+ + +You will probably want to collect domain-dependent defines into one +file, referenced by the DOMAIN macro. For example, our Berkeley +domain file includes definitions for several internal distinguished +hosts: + +UUCP_RELAY The host that will accept UUCP-addressed email. + If not defined, all UUCP sites must be directly + connected. +BITNET_RELAY The host that will accept BITNET-addressed email. + If not defined, the .BITNET pseudo-domain won't work. +DECNET_RELAY The host that will accept DECNET-addressed email. + If not defined, the .DECNET pseudo-domain and addresses + of the form node::user will not work. +FAX_RELAY The host that will accept mail to the .FAX pseudo-domain. + The "fax" mailer overrides this value. +LOCAL_RELAY DEPRECATED. The site that will handle unqualified + names -- that is, names with out an @domain extension. + If not set, they are assumed to belong on this machine. + This allows you to have a central site to store a + company- or department-wide alias database. This + only works at small sites, and only with some user + agents. +LUSER_RELAY The site that will handle lusers -- that is, apparently + local names that aren't local accounts or aliases. + +Any of these can be either ``mailer:hostname'' (in which case the +mailer is the internal mailer name, such as ``uucp-new'' and the hostname +is the name of the host as appropriate for that mailer) or just a +``hostname'', in which case a default mailer type (usually ``relay'', +a variant on SMTP) is used. WARNING: if you have a wildcard MX +record matching your domain, you probably want to define these to +have a trailing dot so that you won't get the mail diverted back +to yourself. + +The domain file can also be used to define a domain name, if needed +(using "DD<domain>") and set certain site-wide features. If all hosts +at your site masquerade behind one email name, you could also use +MASQUERADE_AS here. + +You do not have to define a domain -- in particular, if you are a +single machine sitting off somewhere, it is probably more work than +it's worth. This is just a mechanism for combining "domain dependent +knowledge" into one place. + ++---------+ +| MAILERS | ++---------+ + +There are fewer mailers supported in this version than the previous +version, owing mostly to a simpler world. As a general rule, put the +MAILER definitions last in your .mc file, and always put MAILER(smtp) +before MAILER(uucp) -- several features and definitions will modify +the definition of mailers, and the smtp mailer modifies the UUCP +mailer. + +local The local and prog mailers. You will almost always + need these; the only exception is if you relay ALL + your mail to another site. This mailer is included + automatically. + +smtp The Simple Mail Transport Protocol mailer. This does + not hide hosts behind a gateway or another other + such hack; it assumes a world where everyone is + running the name server. This file actually defines + four mailers: "smtp" for regular (old-style) SMTP to + other servers, "esmtp" for extended SMTP to other + servers, "smtp8" to do SMTP to other servers without + converting 8-bit data to MIME (essentially, this is + your statement that you know the other end is 8-bit + clean even if it doesn't say so), and "relay" for + transmission to our RELAY_HOST, LUSER_RELAY, or + MAILER_HUB. + +uucp The Unix-to-Unix Copy Program mailer. Actually, this + defines two mailers, "uucp-old" (a.k.a. "uucp") and + "uucp-new" (a.k.a. "suucp"). The latter is for when you + know that the UUCP mailer at the other end can handle + multiple recipients in one transfer. If the smtp mailer + is also included in your configuration, two other mailers + ("uucp-dom" and "uucp-uudom") are also defined [warning: + you MUST specify MAILER(smtp) before MAILER(uucp)]. When you + include the uucp mailer, sendmail looks for all names in + the $=U class and sends them to the uucp-old mailer; all + names in the $=Y class are sent to uucp-new; and all + names in the $=Z class are sent to uucp-uudom. Note that + this is a function of what version of rmail runs on + the receiving end, and hence may be out of your control. + See the section below describing UUCP mailers in more + detail. + +usenet Usenet (network news) delivery. If this is specified, + an extra rule is added to ruleset 0 that forwards all + local email for users named ``group.usenet'' to the + ``inews'' program. Note that this works for all groups, + and may be considered a security problem. + +fax Facsimile transmission. This is experimental and based + on Sam Leffler's FlexFAX software. For more information, + see below. + +pop Post Office Protocol. + +procmail An interface to procmail (does not come with sendmail). + This is designed to be used in mailertables. For example, + a common question is "how do I forward all mail for a given + domain to a single person?". If you have this mailer + defined, you could set up a mailertable reading: + + host.com procmail:/etc/procmailrcs/host.com + + with the file /etc/procmailrcs/host.com reading: + + :0 # forward mail for host.com + ! -oi -f $1 person@other.host + + This would arrange for (anything)@host.com to be sent + to person@other.host. Within the procmail script, $1 is + the name of the sender and $2 is the name of the recipient. + If you use this with FEATURE(local_procmail), the FEATURE + should be listed first. + +mail11 The DECnet mail11 mailer, useful only if you have the mail11 + program from gatekeeper.dec.com:/pub/DEC/gwtools (and + DECnet, of course). This is for Phase IV DECnet support; + if you have Phase V at your site you may have additional + problems. + +phquery The phquery program. This is somewhat counterintuitively + referenced as the "ph" mailer internally. It can be used + to do CCSO name server lookups. The phquery program, which + this mailer uses, is distributed with the ph client. + +cyrus The cyrus and cyrusbb mailers. The cyrus mailer delivers to + a local cyrus user. this mailer can make use of the + "user+detail@local.host" syntax; it will deliver the mail to + the user's "detail" mailbox if the mailbox's ACL permits. + The cyrusbb mailer delivers to a system-wide cyrus mailbox + if the mailbox's ACL permits. + + +The local mailer accepts addresses of the form "user+detail", where +the "+detail" is not used for mailbox matching but is available +to certain local mail programs (in particular, see FEATURE(local_procmail)). +For example, "eric", "eric+sendmail", and "eric+sww" all indicate +the same user, but additional arguments <null>, "sendmail", and "sww" +may be provided for use in sorting mail. + + ++----------+ +| FEATURES | ++----------+ + +Special features can be requested using the "FEATURE" macro. For +example, the .mc line: + + FEATURE(use_cw_file) + +tells sendmail that you want to have it read an /etc/sendmail.cw +file to get values for class $=w. The FEATURE may contain a single +optional parameter -- for example: + + FEATURE(mailertable, dbm /usr/lib/mailertable) + +Available features are: + +use_cw_file Read the file /etc/sendmail.cw file to get alternate + names for this host. This might be used if you were + on a host that MXed for a dynamic set of other + hosts. If the set is static, just including the line + "Cw<name1> <name2> ..." is probably superior. + The actual filename can be overridden by redefining + confCW_FILE. + +use_ct_file Read the file /etc/sendmail.ct file to get the names + of users that will be ``trusted'', that is, able to + set their envelope from address using -f without + generating a warning message. + The actual filename can be overridden by redefining + confCT_FILE. + +redirect Reject all mail addressed to "address.REDIRECT" with + a ``551 User not local; please try <address>'' message. + If this is set, you can alias people who have left + to their new address with ".REDIRECT" appended. + +nouucp Don't do anything special with UUCP addresses at all. + +nocanonify Don't pass addresses to $[ ... $] for canonification. + This would generally only be used by sites that only + act as mail gateways or which have user agents that do + full canonification themselves. You may also want to + use "define(`confBIND_OPTS',`-DNSRCH -DEFNAMES')" to + turn off the usual resolver options that do a similar + thing. + +stickyhost If set, email sent to "user@local.host" are marked + as "sticky" -- that is, the local addresses aren't + matched against UDB and don't go through ruleset 5. + This is used if you want a set up where "user" is + not necessarily the same as "user@local.host", e.g., + to make a distinct domain-wide namespace. Prior to + 8.7 this was the default, and notsticky was used to + turn this off. + +mailertable Include a "mailer table" which can be used to override + routing for particular domains. The argument of the + FEATURE may be the key definition. If none is specified, + the definition used is: + hash -o /etc/mailertable + Keys in this database are fully qualified domain names + or partial domains preceded by a dot -- for example, + "vangogh.CS.Berkeley.EDU" or ".CS.Berkeley.EDU". + Values must be of the form: + mailer:domain + where "mailer" is the internal mailer name, and "domain" + is where to send the message. These maps are not + reflected into the message header. + +domaintable Include a "domain table" which can be used to provide + domain name mapping. Use of this should really be + limited to your own domains. It may be useful if you + change names (e.g., your company changes names from + oldname.com to newname.com). The argument of the + FEATURE may be the key definition. If none is specified, + the definition used is: + hash -o /etc/domaintable + The key in this table is the domain name; the value is + the new (fully qualified) domain. Anything in the + domaintable is reflected into headers; that is, this + is done in ruleset 3. + +bitdomain Look up bitnet hosts in a table to try to turn them into + internet addresses. The table can be built using the + bitdomain program contributed by John Gardiner Myers. + The argument of the FEATURE may be the key definition; if + none is specified, the definition used is: + hash -o /etc/bitdomain.db + Keys are the bitnet hostname; values are the corresponding + internet hostname. + +uucpdomain Similar feature for UUCP hosts. The default map definition + is: + hash -o /etc/uudomain.db + At the moment there is no automagic tool to build this + database. + +always_add_domain + Include the local host domain even on locally delivered + mail. Normally it is not added unless it is already + present. + +allmasquerade If masquerading is enabled (using MASQUERADE_AS), this + feature will cause recipient addresses to also masquerade + as being from the masquerade host. Normally they get + the local hostname. Although this may be right for + ordinary users, it can break local aliases. For example, + if you send to "localalias", the originating sendmail will + find that alias and send to all members, but send the + message with "To: localalias@masqueradehost". Since that + alias likely does not exist, replies will fail. Use this + feature ONLY if you can guarantee that the ENTIRE + namespace on your masquerade host supersets all the + local entries. + +nodns We aren't running DNS at our site (for example, + we are UUCP-only connected). It's hard to consider + this a "feature", but hey, it had to go somewhere. + +nullclient This is a special case -- it creates a stripped down + configuration file containing nothing but support for + forwarding all mail to a central hub via a local + SMTP-based network. The argument is the name of that + hub. + + The only other feature that should be used in conjunction + with this one is "nocanonify" (this causes addresses to + be sent unqualified via the SMTP connection; normally + they are qualifed with the masquerade name, which + defaults to the name of the hub machine). No mailers + should be defined. No aliasing or forwarding is done. + +local_procmail Use procmail as the local mailer. This mailer can + make use of the "user+indicator@local.host" syntax; + normally the +indicator is just tossed, but by default + it is passed as the -a argument to procmail. The + argument to this feature is the pathname of procmail, + which defaults to /usr/local/bin/procmail. + +bestmx_is_local Accept mail as though locally addressed for any host that + lists us as the best possible MX record. This generates + additional DNS traffic, but should be OK for low to + medium traffic hosts. THIS FEATURE IS FUNDAMENTALLY + INCOMPATIBLE WITH WILDCARD MX RECORDS!!! If you have + a wildcard MX record that matches your domain, you + cannot use this feature. + +smrsh Use the SendMail Restricted SHell (smrsh) provided + with the distribution instead of /bin/sh for mailing + to programs. This improves the ability of the local + system administrator to control what gets run via + e-mail. If an argument is provided it is used as the + pathname to smrsh; otherwise, /usr/local/etc/smrsh is + assumed. + + ++-------+ +| HACKS | ++-------+ + +Some things just can't be called features. To make this clear, +they go in the hack subdirectory and are referenced using the HACK +macro. These will tend to be site-dependent. The release +includes the Berkeley-dependent "cssubdomain" hack (that makes +sendmail accept local names in either Berkeley.EDU or CS.Berkeley.EDU; +this is intended as a short-term aid while we move hosts into +subdomains. + + ++--------------------+ +| SITE CONFIGURATION | ++--------------------+ + + ***************************************************** + * This section is really obsolete, and is preserved * + * only for back compatibility. You should plan on * + * using mailertables for new installations. In * + * particular, it doesn't work for the newer forms * + * of UUCP mailers, such as uucp-uudom. * + ***************************************************** + +Complex sites will need more local configuration information, such as +lists of UUCP hosts they speak with directly. This can get a bit more +tricky. For an example of a "complex" site, see cf/ucbvax.mc. + +If your host is known by several different names, you need to augment +the $=w class. This is a list of names by which you are known, and +anything sent to an address using a host name in this list will be +treated as local mail. You can do this in two ways: either create +the file /etc/sendmail.cw containing a list of your aliases (one per +line), and use ``FEATURE(use_cw_file)'' in the .mc file, or add the +line: + + Cw alias.host.name + +at the end of that file. See the ``vangogh.mc'' file for an example. +Be sure you use the fully-qualified name of the host, rather than a +short name. + +The SITECONFIG macro allows you to indirectly reference site-dependent +configuration information stored in the siteconfig subdirectory. For +example, the line + + SITECONFIG(uucp.ucbvax, ucbvax, U) + +reads the file uucp.ucbvax for local connection information. The +second parameter is the local name (in this case just "ucbvax" since +it is locally connected, and hence a UUCP hostname). The third +parameter is the name of both a macro to store the local name (in +this case, $U) and the name of the class (e.g., $=U) in which to store +the host information read from the file. Another SITECONFIG line reads + + SITECONFIG(uucp.ucbarpa, ucbarpa.Berkeley.EDU, W) + +This says that the file uucp.ucbarpa contains the list of UUCP sites +connected to ucbarpa.Berkeley.EDU. The $=W class will be used to +store this list, and $W is defined to be ucbarpa.Berkeley.EDU, that +is, the name of the relay to which the hosts listed in uucp.ucbarpa +are connected. [The machine ucbarpa is gone now, but I've left +this out-of-date configuration file around to demonstrate how you +might do this.] + +Note that the case of SITECONFIG with a third parameter of ``U'' is +special; the second parameter is assumed to be the UUCP name of the +local site, rather than the name of a remote site, and the UUCP name +is entered into $=w (the list of local hostnames) as $U.UUCP. + +The siteconfig file (e.g., siteconfig/uucp.ucbvax.m4) contains nothing +more than a sequence of SITE macros describing connectivity. For +example: + + SITE(cnmat) + SITE(sgi olympus) + +The second example demonstrates that you can use two names on the +same line; these are usually aliases for the same host (or are at +least in the same company). + + ++--------------------+ +| USING UUCP MAILERS | ++--------------------+ + +It's hard to get UUCP mailers right because of the extremely ad hoc +nature of UUCP addressing. These config files are really designed +for domain-based addressing, even for UUCP sites. + +There are four UUCP mailers available. The choice of which one to +use is partly a matter of local preferences and what is running at +the other end of your UUCP connection. Unlike good protocols that +define what will go over the wire, UUCP uses the policy that you +should do what is right for the other end; if they change, you have +to change. This makes it hard to do the right thing, and discourages +people from updating their software. In general, if you can avoid +UUCP, please do. + +The major choice is whether to go for a domainized scheme or a +non-domainized scheme. This depends entirely on what the other +end will recognize. If at all possible, you should encourage the +other end to go to a domain-based system -- non-domainized addresses +don't work entirely properly. + +The four mailers are: + + uucp-old (obsolete name: "uucp") + This is the oldest, the worst (but the closest to UUCP) way of + sending messages accros UUCP connections. It does bangify + everything and prepends $U (your UUCP name) to the sender's + address (which can already be a bang path itself). It can + only send to one address at a time, so it spends a lot of + time copying duplicates of messages. Avoid this if at all + possible. + + uucp-new (obsolete name: "suucp") + The same as above, except that it assumes that in one rmail + command you can specify several recipients. It still has a + lot of other problems. + + uucp-dom + This UUCP mailer keeps everything as domain addresses. + Basically, it uses the SMTP mailer rewriting rules. This mailer + is only included if MAILER(smtp) is also specified. + + Unfortunately, a lot of UUCP mailer transport agents require + bangified addresses in the envelope, although you can use + domain-based addresses in the message header. (The envelope + shows up as the From_ line on UNIX mail.) So.... + + uucp-uudom + This is a cross between uucp-new (for the envelope addresses) + and uucp-dom (for the header addresses). It bangifies the + envelope sender (From_ line in messages) without adding the + local hostname, unless there is no host name on the address + at all (e.g., "wolf") or the host component is a UUCP host name + instead of a domain name ("somehost!wolf" instead of + "some.dom.ain!wolf"). This is also included only if MAILER(smtp) + is also specified. + +Examples: + +We are on host grasp.insa-lyon.fr (UUCP host name "grasp"). The +following summarizes the sender rewriting for various mailers. + +Mailer sender rewriting in the envelope +------ ------ ------------------------- +uucp-{old,new} wolf grasp!wolf +uucp-dom wolf wolf@grasp.insa-lyon.fr +uucp-uudom wolf grasp.insa-lyon.fr!wolf + +uucp-{old,new} wolf@fr.net grasp!fr.net!wolf +uucp-dom wolf@fr.net wolf@fr.net +uucp-uudom wolf@fr.net fr.net!wolf + +uucp-{old,new} somehost!wolf grasp!somehost!wolf +uucp-dom somehost!wolf somehost!wolf@grasp.insa-lyon.fr +uucp-uudom somehost!wolf grasp.insa-lyon.fr!somehost!wolf + +If you are using one of the domainized UUCP mailers, you really want +to convert all UUCP addresses to domain format -- otherwise, it will +do it for you (and probably not the way you expected). For example, +if you have the address foo!bar!baz (and you are not sending to foo), +the heuristics will add the @uucp.relay.name or @local.host.name to +this address. However, if you map foo to foo.host.name first, it +will not add the local hostname. You can do this using the uucpdomain +feature. + + ++-------------------+ +| TWEAKING RULESETS | ++-------------------+ + +For more complex configurations, you can define special rules. +The macro LOCAL_RULE_3 introduces rules that are used in canonicalizing +the names. Any modifications made here are reflected in the header. + +A common use is to convert old UUCP addreses to SMTP addresses using +the UUCPSMTP macro. For example: + + LOCAL_RULE_3 + UUCPSMTP(decvax, decvax.dec.com) + UUCPSMTP(research, research.att.com) + +will cause addresses of the form "decvax!user" and "research!user" +to be converted to "user@decvax.dec.com" and "user@research.att.com" +respectively. + +This could also be used to look up hosts in a database map: + + LOCAL_RULE_3 + R$* < @ $+ > $* $: $1 < @ $(hostmap $2 $) > $3 + +This map would be defined in the LOCAL_CONFIG portion, as shown below. + +Similarly, LOCAL_RULE_0 can be used to introduce new parsing rules. +For example, new rules are needed to parse hostnames that you accept +via MX records. For example, you might have: + + LOCAL_RULE_0 + R$+ <@ host.dom.ain.> $#uucp $@ cnmat $: $1 < @ host.dom.ain.> + +You would use this if you had installed an MX record for cnmat.Berkeley.EDU +pointing at this host; this rule catches the message and forwards it on +using UUCP. + +You can also tweak rulesets 1 and 2 using LOCAL_RULE_1 and LOCAL_RULE_2. +These rulesets are normally empty. + +A similar macro is LOCAL_CONFIG. This introduces lines added after the +boilerplate option setting but before rulesets, and can be used to +declare local database maps or whatever. For example: + + LOCAL_CONFIG + Khostmap hash /etc/hostmap.db + Kyplocal nis -m hosts.byname + + ++---------------------------+ +| MASQUERADING AND RELAYING | ++---------------------------+ + +You can have your host masquerade as another using + + MASQUERADE_AS(host.domain) + +This causes outgoing SMTP mail to be labeled as coming from the +indicated domain, rather than $j. One normally masquerades as one +of one's own subdomains (for example, it's unlikely that I would +choose to masquerade as an MIT site). + +The masquerade name is not normally canonified, so it is important +that it be your One True Name, that is, fully qualified and not a +CNAME. + +Normally the only addresses that are masqueraded are those that come +from this host (that is, are either unqualified or in $=w, the list +of local domain names). You can augment this list using + + MASQUERADE_DOMAIN(otherhost.domain) + +The effect of this is that although mail to user@otherhost.domain +will not be delivered locally, any mail including any user@otherhost.domain +will, when relayed, be rewritten to have the MASQUERADE_AS address. +This can be a space-separated list of names. + +If these names are in a file, you can use + + MASQUERADE_DOMAIN_FILE(filename) + +to read the list of names from the indicated file. + +Normally only header addresses are masqueraded. If you want to +masquerade the envelope as well, use + + FEATURE(masquerade_envelope) + +There are always users that need to be "exposed" -- that is, their +internal site name should be displayed instead of the masquerade name. +Root is an example. You can add users to this list using + + EXPOSED_USER(usernames) + +This adds users to class E; you could also use something like + + FE/etc/sendmail.cE + +You can also arrange to relay all unqualified names (that is, names +without @host) to a relay host. For example, if you have a central +email server, you might relay to that host so that users don't have +to have .forward files or aliases. You can do this using + + define(`LOCAL_RELAY', mailer:hostname) + +The ``mailer:'' can be omitted, in which case the mailer defaults to +"smtp". There are some user names that you don't want relayed, perhaps +because of local aliases. A common example is root, which may be +locally aliased. You can add entries to this list using + + LOCAL_USER(usernames) + +This adds users to class L; you could also use something like + + FL/etc/sendmail.cL + +If you want all incoming mail sent to a centralized hub, as for a +shared /var/spool/mail scheme, use + + define(`MAIL_HUB', mailer:hostname) + +Again, ``mailer:'' defaults to "smtp". If you define both LOCAL_RELAY +and MAIL_HUB _AND_ you have FEATURE(stickyhost), unqualified names will +be sent to the LOCAL_RELAY and other local names will be sent to MAIL_HUB. +Names in $=L will be delivered locally, so you MUST have aliases or +.forward files for them. + +For example, if are on machine mastodon.CS.Berkeley.EDU and you have +FEATURE(stickyhost), the following combinations of settings will have the +indicated effects: + +email sent to.... eric eric@mastodon.CS.Berkeley.EDU + +LOCAL_RELAY set to mail.CS.Berkeley.EDU (delivered locally) +mail.CS.Berkeley.EDU (no local aliasing) (aliasing done) + +MAIL_HUB set to mammoth.CS.Berkeley.EDU mammoth.CS.Berkeley.EDU +mammoth.CS.Berkeley.EDU (aliasing done) (aliasing done) + +Both LOCAL_RELAY and mail.CS.Berkeley.EDU mammoth.CS.Berkeley.EDU +MAIL_HUB set as above (no local aliasing) (aliasing done) + +If you do not have FEATURE(stickyhost) set, then LOCAL_RELAY and +MAIL_HUB act identically, with MAIL_HUB taking precedence. + +If you want all outgoing mail to go to a central relay site, define +SMART_HOST as well. Briefly: + + LOCAL_RELAY applies to unqualifed names (e.g., "eric"). + MAIL_HUB applies to names qualified with the name of the + local host (e.g., "eric@mastodon.CS.Berkeley.EDU"). + SMART_HOST applies to names qualified with other hosts. + +However, beware that other relays (e.g., UUCP_RELAY, BITNET_RELAY, +DECNET_RELAY, and FAX_RELAY) take precedence over SMART_HOST, so if you +really want absolutely everything to go to a single central site you will +need to unset all the other relays -- or better yet, find or build a +minimal config file that does this. + + ++-------------------------------+ +| NON-SMTP BASED CONFIGURATIONS | ++-------------------------------+ + +These configuration files are designed primarily for use by SMTP-based +sites. I don't pretend that they are well tuned for UUCP-only or +UUCP-primarily nodes (the latter is defined as a small local net +connected to the rest of the world via UUCP). However, there is one +hook to handle some special cases. + +You can define a ``smart host'' that understands a richer address syntax +using: + + define(`SMART_HOST', mailer:hostname) + +In this case, the ``mailer:'' defaults to "relay". Any messages that +can't be handled using the usual UUCP rules are passed to this host. + +If you are on a local SMTP-based net that connects to the outside +world via UUCP, you can use LOCAL_NET_CONFIG to add appropriate rules. +For example: + + define(`SMART_HOST', suucp:uunet) + LOCAL_NET_CONFIG + R$* < @ $* .$m. > $* $#smtp $@ $2.$m. $: $1 < @ $2.$m. > $3 + +This will cause all names that end in your domain name ($m) via +SMTP; anything else will be sent via suucp (smart UUCP) to uunet. +If you have FEATURE(nocanonify), you may need to omit the dots after +the $m. If you are running a local DNS inside your domain which is +not otherwise connected to the outside world, you probably want to +use: + + define(`SMART_HOST', smtp:fire.wall.com) + LOCAL_NET_CONFIG + R$* < @ $* . > $* $#smtp $@ $2. $: $1 < @ $2. > $3 + +That is, send directly only to things you found in your DNS lookup; +anything else goes through SMART_HOST. + +If you are not running DNS at all, it is important to use +FEATURE(nodns) to avoid having sendmail queue everything waiting +for the name server to come up. + + ++-----------+ +| WHO AM I? | ++-----------+ + +Normally, the $j macro is automatically defined to be your fully +qualified domain name (FQDN). Sendmail does this by getting your +host name using gethostname and then calling gethostbyname on the +result. For example, in some environments gethostname returns +only the root of the host name (such as "foo"); gethostbyname is +supposed to return the FQDN ("foo.bar.com"). In some (fairly rare) +cases, gethostbyname may fail to return the FQDN. In this case +you MUST define confDOMAIN_NAME to be your fully qualified domain +name. This is usually done using: + + Dmbar.com + define(`confDOMAIN_NAME', `$w.$m')dnl + + ++--------------------+ +| USING MAILERTABLES | ++--------------------+ + +To use FEATURE(mailertable), you will have to create an external +database containing the routing information for various domains. +For example, a mailertable file in text format might be: + + .my.domain xnet:%1.my.domain + uuhost1.my.domain suucp:uuhost1 + .bitnet smtp:relay.bit.net + +This should normally be stored in /etc/mailertable. The actual +database version of the mailertable is built using: + + makemap hash /etc/mailertable.db < /etc/mailertable + +The semantics are simple. Any LHS entry that does not begin with +a dot matches the full host name indicated. LHS entries beginning +with a dot match anything ending with that domain name -- that is, +they can be thought of as having a leading "*" wildcard. Matching +is done in order of most-to-least qualified -- for example, even +though ".my.domain" is listed first in the above example, an entry +of "uuhost1.my.domain" will match the second entry since it is +more explicit. + +The RHS should always be a "mailer:host" pair. The mailer is the +configuration name of a mailer (that is, an `M' line in the +sendmail.cf file). The "host" will be the hostname passed to +that mailer. In domain-based matches (that is, those with leading +dots) the "%1" may be used to interpolate the wildcarded part of +the host name. For example, the first line above sends everything +addressed to "anything.my.domain" to that same host name, but using +the (presumably experimental) xnet mailer. + +In some cases you may want to temporarily turn off MX records, +particularly on gateways. For example, you may want to MX +everything in a domain to one machine that then forwards it +directly. To do this, you might use the DNS configuration: + + *.domain. IN MX 0 relay.machine + +and on relay.machine use the mailertable: + + .domain smtp:[gateway.domain] + +The [square brackets] turn off MX records for this host only. +If you didn't do this, the mailertable would use the MX record +again, which would give you an MX loop. + + ++--------------------------------+ +| USING USERDB TO MAP FULL NAMES | ++--------------------------------+ + +The user database was not originally intended for mapping full names +to login names (e.g., Eric.Allman => eric), but some people are using +it that way. (I would recommend that you set up aliases for this +purpose instead -- since you can specify multiple alias files, this +is fairly easy.) The intent was to locate the default maildrop at +a site, but allow you to override this by sending to a specific host. + +If you decide to set up the user database in this fashion, it is +imperative that you not use FEATURE(stickyhost) -- otherwise, +e-mail sent to Full.Name@local.host.name will be rejected. + +To build the internal form of the user database, use: + + makemap btree /usr/data/base.db < /usr/data/base.txt + +As a general rule, I am adamantly opposed to using full names as +e-mail addresses, since they are not in any sense unique. For example, +the Unix software-development community has two Andy Tannenbaums, +at least two well-known Peter Deutsches, and at one time Bell Labs +had two Stephen R. Bournes with offices along the same hallway. +Which one will be forced to suffer the indignity of being +Stephen_R_Bourne_2? The less famous of the two, or the one that +was hired later? + +Finger should handle full names (and be fuzzy). Mail should use +handles, and not be fuzzy. [Not that I expect anyone to pay any +attention to my opinions.] + + ++--------------------------------+ +| MISCELLANEOUS SPECIAL FEATURES | ++--------------------------------+ + +Plussed users + Sometimes it is convenient to merge configuration on a + centralized mail machine, for example, to forward all + root mail to a mail server. In this case it might be + useful to be able to treat the root addresses as a class + of addresses with subtle differences. You can do this + using plussed users. For example, a client might include + the alias: + + root: root+client1@server + + On the server, this will match an alias for "root+client1". + If that is not found, the alias "root+*" will be tried, + then "root". + + ++----------------+ +| SECURITY NOTES | ++----------------+ + +A lot of sendmail security comes down to you. Sendmail 8 is much +more careful about checking for security problems than previous +versions, but there are some things that you still need to watch +for. In particular: + +* Make sure the aliases file isn't writable except by trusted + system personnel. This includes both the text and database + version. + +* Make sure that other files that sendmail reads, such as the + mailertable, is only writable by trusted system personnel. + +* The queue directory should not be world writable PARTICULARLY + if your system allows "file giveaways" (that is, if a non-root + user can chown any file they own to any other user). + +* If your system allows file giveaways, DO NOT create a publically + writable directory for forward files. This will allow anyone + to steal anyone else's e-mail. Instead, create a script that + copies the .forward file from users' home directories once a + night (if you want the non-NFS-mounted forward directory). + +* If your system allows file giveaways, you'll find that + sendmail is much less trusting of :include: files -- in + particular, you'll have to have /SENDMAIL/ANY/SHELL/ in + /etc/shells before they will be trusted (that is, before + files and programs listed in them will be honored). + +In general, file giveaways are a mistake -- if you can turn them +off I recommend you do so. + + ++------------------+ +| FlexFAX SOFTWARE | ++------------------+ + +Sam Leffler's FlexFAX software is still in beta test -- but he expects a +public version out "later this week" [as of 3/1/93]. The following +blurb is direct from Sam: + + $Header: /usr/people/sam/fax/RCS/HOWTO,v 1.14 93/05/24 11:42:16 sam Exp $ + + How To Obtain This Software (in case all you get is this file) + -------------------------------------------------------------- + The source code is available for public ftp on + sgi.com sgi/fax/v2.1.src.tar.Z + (192.48.153.1) + + You can also obtain inst'able images for Silicon Graphics machines from + sgi.com sgi/fax/v2.1.inst.tar + (192.48.153.1) + + For example, + % ftp -n sgi.com + .... + ftp> user anonymous + ... <type in password> + ftp> cd sgi/fax + ftp> binary + ftp> get v2.1.src.tar.Z + + In general, the latest version of the 2.1 release of the software is + always available as "v2.1.src.tar.Z" or "v2.1.inst.tar" in the ftp + directory. This file is a link to the appropriate released version (so + don't waste your time retrieving the linked file as well!) Any files of + the form v2.1.*.patch are shell scripts that can be used to patch older + versions of the source code. For example, the file v2.1.0.patch would + contain patches to update v2.1.0.tar.Z. (Note to beta testers: this is + different than the naming conventions used during beta testing.) Patch + files only work to go between consecutive versions, so if you are + multiple versions behind the latest release, you will need to apply + each patch file between your current version and the latest. + + + Obtaining the Software by Electronic Mail + ----------------------------------------- + Do not send me requests for the software; they will be ignored (without + response). If you cannot use FTP at all, there is a service called + "ftpmail" available from gatekeeper.dec.com: you can send e-mail to + this machine and it will use FTP to retrieve files for you and send you + the files back again via e-mail. To find out more about the ftpmail + service, send a message to "ftpmail@gatekeeper.dec.com" whose body + consists of the single line "help". + + + Obtaining the Software Within Silicon Graphics + ---------------------------------------------- + Internal to Silicon Graphics there are inst'able images on the host + flake.asd in the directory /usr/dist. Thus you can do something like: + + % inst -f flake.asd.sgi.com:/usr/dist/flexfax + + to install the latest version of the software on your machine. + + + What to do Once You've Retrieved Stuff + -------------------------------------- + The external distributions come in a compressed or uncompressed tar + file. To extract the source distribution: + + % zcat v2.1.src.tar.Z | tar xf - + + (uncompress and extract individual files in current directory). To + unpack and install the client portion of the inst'able distribution: + + % mkdir dist + % cd dist; tar xf ../v2.1.inst.tar; cd .. + % inst -f dist/flexfax + ... + inst> go + + (Note, the dist subdirectory is because some versions of inst fail if + the files are in the current directory.) Server binaries are also + included in the inst'able images as flexfax.server.*. They are not + installed by default, so to get them also you need to do: + + % inst -f flexfax + ... + inst> install flexfax.server.* + inst> go + + The SGI binaries were built for Version 4.0.5H of the IRIX operating + system. They should work w/o problem on earlier versions of the + system, but I have not fully tested this. Also, note that to install a + server on an SGI machine, you need to have installed the Display + PostScript execution environment product (dps_eoe). Otherwise, the fax + server will not be able to convert PostScript to facsimile for + transmission. + + If you are working from the source distribution, look at the file + README in the top of the source tree. If you are working from the inst + images, the subsystem flexfax.man.readme contains the README file and + other useful pieces of information--the installed files are placed in + the directory /usr/local/doc/flexfax). Basically you will need to run + the faxaddmodem script to setup and configure your fax modem. Consult + the README file and the manual page for faxaddmodem for information. + + + FlexFAX Mail List + ----------------- + A mailing list for users of this software is located on sgi.com. + If you want to join this mailing list or have a list-related request + such as getting your name removed from it, send a request to + + majordomo@whizzer.wpd.sgi.com + + For example, to subscribe, send the line "subscribe flexfax" in + the body of your message. The line "help" will return a list of + the commands understood by the mailing list management software. + + Submissions (including bug reports) should be directed to: + + flexfax@sgi.com + + When corresponding about this software please always specify what + version you have, what system you're running on, and, if the problem is + specific to your modem, identify the modem and firmware revision. + + ++--------------------------------+ +| TWEAKING CONFIGURATION OPTIONS | ++--------------------------------+ + +There are a large number of configuration options that don't normally +need to be changed. However, if you feel you need to tweak them, you +can define the following M4 variables. This list is shown in four +columns: the name you define, the default value for that definition, +the option or macro that is affected (either Ox for an option or Dx +for a macro), and a brief description. Greater detail of the semantics +can be found in the Installation and Operations Guide. + +Some options are likely to be deprecated in future versions -- that is, +the option is only included to provide back-compatibility. These are +marked with "*". + +Remember that these options are M4 variables, and hence may need to +be quoted. In particular, arguments with commas will usually have to +be ``double quoted, like this phrase'' to avoid having the comma +confuse things.

See also discussion of + $=U, $=Y, and $=Z in the MAILER(uucp) + section. +confLOCAL_MAILER - [local] The mailer name used when + local connectivity is required. + Almost always "local". +confRELAY_MAILER - [relay] The default mailer name used + for relaying any mail (e.g., to a + BITNET_RELAY, a SMART_HOST, or + whatever). This can reasonably be + "uucp-new" if you are on a + UUCP-connected site. +confSEVEN_BIT_INPUT SevenBitInput [False] Force input to seven bits? +confEIGHT_BIT_HANDLING EightBitMode [pass8] 8-bit data handling +confALIAS_WAIT AliasWait [10m] Time to wait for alias file + rebuild until you get bored and + decide that the apparently pending + rebuild failed. +confMIN_FREE_BLOCKS MinFreeBlocks [100] Minimum number of free blocks on + queue filesystem to accept SMTP mail. + (Prior to 8.7 this was minfree/maxsize, + where minfree was the number of free + blocks and maxsize was the maximum + message size. Use confMAX_MESSAGE_SIZE + for the second value now.) +confMAX_MESSAGE_SIZE MaxMessageSize The maximum size of messages that will + be accepted (in bytes). +confBLANK_SUB BlankSub [.] Blank (space) substitution + character. +confCON_EXPENSIVE HoldExpensive [False] Avoid connecting immediately + to mailers marked expensive? +confCHECKPOINT_INTERVAL CheckpointInterval + Checkpoint queue files every N + recipients. +confDELIVERY_MODE DeliveryMode [background] Default delivery mode. +confAUTO_REBUILD AutoRebuildAliases + Automatically rebuild alias + file if needed. +confERROR_MODE ErrorMode Error message mode. +confERROR_MESSAGE ErrorHeader Error message header/file. +confSAVE_FROM_LINES SafeFromLine Save extra leading From_ lines. +confTEMP_FILE_MODE TempFileMode [0600] Temporary file mode. +confMATCH_GECOS MatchGECOS Match GECOS field. +confMAX_HOP MaxHopCount Maximum hop count. +confIGNORE_DOTS* IgnoreDots Ignore dot as terminator for incoming + messages? +confBIND_OPTS ResolverOptions Default options for DNS resolver. +confMIME_FORMAT_ERRORS* SendMimeErrors [True] Send error messages as MIME- + encapsulated messages per RFC 1344. +confFORWARD_PATH ForwardPath [$z/.forward.$w:$z/.forward] + The colon-separated list of places to + search for .forward files.

Since this does + DNS lookups on every address, it can + slow down the alias rebuild process + considerably on large alias files. +confOLD_STYLE_HEADERS* OldStyleHeaders [True] Assume that headers without + special chars are old style. +confDAEMON_OPTIONS DaemonPortOptions + SMTP daemon options. +confPRIVACY_FLAGS PrivacyOptions [authwarnings] Privacy flags. +confCOPY_ERRORS_TO PostmasterCopy Address for additional copies of all + error messages. +confQUEUE_FACTOR QueueFactor Slope of queue-only function. +confDONT_PRUNE_ROUTES DontPruneRoutes Don't prune down route-addr syntax + addresses to the minimum possible. +confSAFE_QUEUE* SuperSafe [True] Commit all messages to disk + before forking. +confTO_INITIAL Timeout.initial [5m] The timeout waiting for a response + on the initial connect. +confTO_HELO Timeout.helo [5m] The timeout waiting for a response + to a HELO or EHLO command. +confTO_MAIL Timeout.mail [10m] The timeout waiting for a + response to the MAIL command. +confTO_RCPT Timeout.rcpt [1h] The timeout waiting for a response + to the RCPT command. +confTO_DATAINIT Timeout.datainit + [5m] The timeout waiting for a 354 + response from the DATA command. +confTO_DATABLOCK Timeout.datablock + [1h] The timeout waiting for a block + during DATA phase. +confTO_DATAFINAL Timeout.datafinal + [1h] The timeout waiting for a response + to the final "." that terminates a + message. +confTO_RSET Timeout.rset [5m] The timeout waiting for a response + to the RSET command. +confTO_QUIT Timeout.quit [2m] The timeout waiting for a response + to the QUIT command. +confTO_MISC Timeout.misc [2m] The timeout waiting for a response + to other SMTP commands. +confTO_COMMAND Timeout.command [1h] In server SMTP, the timeout waiting + for a command to be issued. +confTO_IDENT Timeout.ident [30s] The timeout waiting for a response + to an IDENT query. +confTO_FILEOPEN Timeout.fileopen + [60s] The timeout waiting for a file + (e.g., :include: file) to be opened. +confTO_QUEUERETURN Timeout.queuereturn + [5d] The timeout before a message is + returned as undeliverable. +confTO_QUEUERETURN_NORMAL + Timeout.queuereturn.normal + [undefined] As above, for normal + priority messages. +confTO_QUEUERETURN_URGENT + Timeout.queuereturn.urgent + [undefined] As above, for urgent + priority messages. +confTO_QUEUERETURN_NONURGENT + Timeout.queuereturn.non-urgent + [undefined] As above, for non-urgent + (low) priority messages. +confTO_QUEUEWARN Timeout.queuewarn + [4h] The timeout before a warning + message is sent to the sender telling + them that the message has been deferred. +confTO_QUEUEWARN_NORMAL Timeout.queuewarn.normal + [undefined] As above, for normal + priority messages. +confTO_QUEUEWARN_URGENT Timeout.queuewarn.urgent + [undefined] As above, for urgent + priority messages. +confTO_QUEUEWARN_NONURGENT + Timeout.queuewarn.non-urgent + [undefined] As above, for non-urgent + (low) priority messages. +confTIME_ZONE TimeZoneSpec [USE_SYSTEM] Time zone info -- can be + USE_SYSTEM to use the system's idea, + USE_TZ to use the user's TZ envariable, + or something else to force that value. +confDEF_USER_ID DefaultUser [1:1] Default user id. +confUSERDB_SPEC UserDatabaseSpec + User database specification. +confFALLBACK_MX FallbackMXhost Fallback MX host. +confTRY_NULL_MX_LIST TryNullMXList If we are the best MX for a host and + haven't made other arrangements, try + connecting to the host directly; + normally this would be a config error. +confQUEUE_LA QueueLA Load average at which queue-only + function kicks in. +confREFUSE_LA RefuseLA Load average at which incoming + SMTP connections are refused. +confWORK_RECIPIENT_FACTOR + RecipientFactor Cost of each recipient. +confSEPARATE_PROC ForkEachJob Run all deliveries in a separate + process. +confWORK_CLASS_FACTOR ClassFactor Priority multiplier for class. +confWORK_TIME_FACTOR RetryFactor Cost of each delivery attempt. +confQUEUE_SORT_ORDER QueueSortOrder Queue sort algorithm: Priority or Host. +confMIN_QUEUE_AGE MinQueueAge The minimum amount of time a job + must sit in the queue between queue + runs. This allows you to set the + queue run interval low for better + resposiveness without trying all + jobs in each run. +confDEF_CHAR_SET DefaultCharSet When converting unlabelled 8 bit + input to MIME, the character set to + use by default. +confSERVICE_SWITCH_FILE ServiceSwitchFile + The file to use for the service switch + on systems that do not have a system- + defined switch. +confDIAL_DELAY DialDelay If a connection fails, wait this long + and try again. This is to allow + "dial on demand" connections to have + enough time to complete a connection. +confNO_RCPT_ACTION NoRecipientAction + What to do if there are no legal + recipient fields (To:, Cc: or Bcc:) + in the message. Legal values can + be "none" to just leave the + nonconforming message as is, "add-to" + to add a To: header with all the + known recipients (which may expose + blind recipients), "add-apparently-to" + to do the same but use Apparently-To: + instead of To:, "add-bcc" to add an + empty Bcc: header, or + "add-to-undisclosed" to add the header + ``To: undisclosed-recipients:;''. + Default is "none". +confSAFE_FILE_ENV SafeFileEnvironment + If set, sendmail will do a chroot() + into this directory before writing + files. +confCOLON_OK_IN_ADDR ColonOkInAddr If set, colons are treated as a regular + character in addresses. If not set, + they are treated as the introducer to + the RFC 822 "group" syntax. Colons are + handled properly in route-addrs. This + option defaults on for V5 and lower + configuration files. +confMAX_QUEUE_RUN_SIZE MaxQueueRunSize If set, limit the maximum size of any + given queue run to this number of + entries. Essentially, this will stop + reading the queue directory after this + number of entries are reached; it does + _not_ pick the highest priority jobs, + so this should be as large as your + system can tolerate. If not set, there + is no limit. +confDONT_EXPAND_CNAMES DontExpandCnames + If set, $[ ... $] lookups that do DNS + based lookups do not expand CNAME + records. This currently violates the + published standards, but the IETF + seems to be moving toward legalizing + this. For example, if "FTP.Foo.ORG" + is a CNAME for "Cruft.Foo.ORG", then + with this option set a lookup of + "FTP" will return "FTP.Foo.ORG"; if + clear it returns "Cruft.FOO.ORG". N.B. + you may not see any effect until your + downstream neighbors stop doing CNAME + lookups as well. +confFROM_LINE UnixFromLine [From $g $d] The From_ line used + when sending to files or programs. +confOPERATORS OperatorChars [.:%@!^/[]+] Address operator + characters. +confSMTP_LOGIN_MSG SmtpGreetingMessage + [$j Sendmail $v/$Z; $b] + The initial (spontaneous) SMTP + greeting message. The word "ESMTP" + will be inserted between the first and + second words to convince other + sendmails to try to speak ESMTP. +confDONT_INIT_GROUPS DontInitGroups If set, the initgroups(3) routine will + never be invoked. You might want to + do this if you are running NIS and you + have a large group map, since this + call does a sequential scan of the map; + in a large site this can cause your + ypserv to run essentially full time. + If you set this, agents run on behalf + of users will only have their primary + (/etc/passwd) group permissions. + +See also the description of OSTYPE for some parameters that can be +tweaked (generally pathnames to mailers). + + ++-----------+ +| HIERARCHY | ++-----------+ + +Within this directory are several subdirectories, to wit: + +m4 General support routines.

It will keep +doing this until no further expansion is possible. +.SH OPTIONS +The default output of +.B expn +can contain many lines which are not valid +email addresses. With the +.I -aa +flag, only expansions that result in legal addresses +are used. Since many mailing lists have an illegal +address or two, the single +.IR -a , +address, flag specifies that a few illegal addresses can +be mixed into the results. More +.I -a +flags vary the ratio. Read the source to track down +the formula. With the +.I -a +option, you should be able to construct a new mailing +list out of an existing one. +.LP +If you wish to limit the number of levels deep that +.B expn +will recurse as it traces addresses, use the +.I -1 +option. For each +.I -1 +another level will be traversed. So, +.I -111 +will traverse no more than three levels deep. +.LP +The normal mode of operation for +.B expn +is to do all of its work silently. +The following options make it more verbose. +It is not necessary to make it verbose to see what it is +doing because as it works, it changes its +.BR argv [0] +variable to reflect its current activity. +To see how it is expanding things, the +.IR -v , +verbose, flag will cause +.B expn +to show each address before +and after translation as it works. +The +.IR -w , +watch, flag will cause +.B expn +to show you its conversations with the mail daemons. +Finally, the +.IR -d , +debug, flag will expose many of the inner workings so that +it is possible to eliminate bugs. +.SH ENVIRONMENT +No enviroment variables are used. +.SH FILES +.PD 0 +.B /tmp/expn$$ +.B temporary file used as input to +.BR nslookup . +.SH SEE ALSO +.BR aliases (5), +.BR sendmail (8), +.BR nslookup (8), +RFC 823, and RFC 1123. +.SH BUGS +Not all mail daemons will implement +.B expn +or +.BR vrfy . +It is not possible to verify addresses that are served +by such daemons. +.LP +When attempting to connect to a system to verify an address, +.B expn +only tries one IP address. Most mail daemons +will try harder. +.LP +It is assumed that you are running domain names and that +the +.BR nslookup (8) +program is available. If not, +.B expn +will not be able to verify many addresses. It will also pause +for a long time unless you change the code where it says +.I $have_nslookup = 1 +to read +.I $have_nslookup = +.IR 0 . +.LP +Lastly, +.B expn +does not handle every valid address.

For small lists it seems overkill, but for +> large lists it could be a major win. + +Sure, I will contribute it; after I sent you mail last night I went ahead +and finished up what I thought needed to be done. I would like to get +some feedback from you on a few items, if you have time. + +There are two programs, mailprio_mkdb and mailprio (source below). + +mailprio_mkdb reads maillog files and creates a DB file of address vs. +delay. I'm not too happy with how it does the averages right now but this +is just a quick hack. However, it should at least order sites that take +days vs. those that deliver on the first pass through. One thing that +would make this information a lot more accurate is if sendmail could log +a "transaction delay" (on failures also), as well as total delivery delay. +Perhaps, as an option, it could maintain the DB file itself? + +mailprio then simply reads a list of addresses from stdin (the mailing +list), and tries to prioritize them according to the info the database. +It collects comment lines and other junk at the top of the file; all +mailprio does is reorder lines, the actual text of the file should +be unchanged to the extent that you can verify it with: + sort sorted_list > checkit; sort mailing-list | diff - checkit +Users with no delay information are put next. The prioritized list is last. +Of course, this function could also be built-into sendmail (eventually). + +Putting "new account" info at the top with the current averaging function +probably adversly affects the prioritized list (at least in the short +term), but putting it at the bottom would not really give the new accounts +a fair chance. I suspect this isn't that big of a problem. I'm running +this here on a list with 461 accounts and about 10 messages per day so +I'll see how it goes. I'll keep some stats on delay times and see what +happens. + +Another thing that would help this situation, is if sendmail had the queue +ordered by site (but you already know this). If you ever get to do per +site queuing you should consider "blocking" a queue for some short period +of time if a connection fails to that site [sendmail does this inside a +single process on a per account basis now right?]; this would allow multiple +sendmails to quickly skip over those sites for people like me that run: + + for i in 1 2 3 4 5 6 7 8 ; do daemon sendmail -q; done + +to flush a queue that has gotten behind. You could also do this inside +sendmail with a parallelism option (when it is time to run the queue, how +many processes to start). + +#! /bin/sh +# This is a shell archive.

MIME) +[RFC1521, RFC1344]. +Neither the IDA group nor most vendors +were modifying +.i sendmail +to conform to these new standards. +It seemed clear that these were ``good things'' +that should be encouraged. +However, since no one was working on a publically available version of +.i sendmail +with these updates, +they were unlikely to be widely deployed any time in the near future. +.pp +There are, of course, other mail transport agents available, +such as +.i MMDF +.\"[ref], +.i zmailer +.\"[ref], +.i smail +.\"[ref], +and +.i PP +.\"[ref]. +However, none of these seemed to be gaining the prominence of +.i sendmail ; +it appeared that most companies would not convert to another +mail transport agent any time in the forseeable future. +However, they might be persuaded to convert to a newer version of +.i sendmail . +.pp +All of these convinced the author +to work on a updated version of +.i sendmail +for public distribution. +.pp +The new version of +.i sendmail +is referred to as version eight (V8). +Versions six and seven were skipped +because of an agreement +that all files in 4.4BSD would be numbered as +.q 8.1 . +Rather than have an external version number +that differed from the file version numbers, +.i sendmail +just jumped directly to V8. +.sh 1 "CHANGES IN VERSION EIGHT" +.pp +The following is a summary of the changes between the last commonly +available version of sendmail from Berkeley (5.67) and the latest +version (8.6.6). +.pp +Many of these are ideas that had been tried in IDA, +but many of them were generalized in V8. +.sh 2 "Performance Enhancements" +.pp +Instead of closing SMTP connections immediately, open connections are +cached for possible future use. There is a limit to the number of +simultaneous open connections and the idle time of any individual +connection. +.pp +This is of best help during queue processing (since there is the +potential of many different messages going to one site), although +it can also help when processing MX records which aren't handled +by MX Piggybacking. +.pp +If two hosts with different names in a single message happen to +have the same set of MX hosts, they can be sent in the same +transaction. Version 8 notices this and tries to batch the messages. +.pp +For example, if two sites ``foo.com'' and ``bar.com'' are both +served by UUNET, they will have the same set of MX hosts and will +be sent in one transaction. UUNET will then split the message +and send it to the two individual hosts. +.sh 2 "RFC 1123 Changes" +.pp +A number of changes have been made to make sendmail ``conditionally +compliant'' (that is, it satisfies all of the MUST clauses and most +but not all of the SHOULD clauses in RFC 1123). +.pp +The major areas of change are (numbers are RFC 1123 section numbers): +.nr ii 0.75i +.ip \(sc5.2.7 +Response to RCPT command is fast. Previously, sendmail +expanded all aliases as far as it could \*- this could +take a very long time, particularly if there were +name server delays. Version 8 only checks for the +existence of an alias and does the expansion later. +It does still do a DNS lookup if there is an explicit host name +in the RCPT command, +but this time is bounded. +.ip \(sc5.2.8 +Numeric IP addresses are logged in Received: lines. +This helps tracing spoofed messages. +.ip \(sc5.2.17 +Self domain literal is properly handled. Previously, +if someone sent to user@[1.2.3.4], where 1.2.3.4 is +your IP address, the mail would probably be rejected +with a ``configuration error''. +Version 8 can handle these addresses. +.ip \(sc5.3.2 +Better control over individual timeouts. RFC 821 specified +no timeouts. Older versions of sendmail had a single +timeout, typically set to two hours. Version 8 allows +the configuration file to set timeouts for various +SMTP commands individually. +.ip \(sc5.3.3 +Error messages are sent as From:<>. This was urged by +RFC 821 and reiterated by RFC 1123, but older versions +of sendmail never really did it properly. Version 8 +does. However, some systems cannot handle this +perfectly legal address; if necessary, you can create +a special mailer that uses the `g' flag to disable this. +.ip \(sc5.3.3 +Error messages are never sent to <>. Previously, +sendmail was happy to send responses-to-responses which +sometimes resulted in responses-to-responses-to-responses +which resulted in .... you get the idea. +.ip \(sc5.3.3 +Route-addrs (the ugly ``<@hosta,@hostb:user@hostc>'' +syntax) are pruned. RFC 821 urged the use of this +bletcherous syntax. RFC 1123 has seen the light and +officially deprecates them, further urging that you +eliminate all but ``user@hostc'' should you receive +one of these things. Version 8 is slightly more generous +than the standards suggest; instead of stripping off all +the route addressees, it only strips hosts off up to +the one before the last one known to DNS, thus allowing +you to have pseudo-hosts such as foo.BITNET. The `R' +option will turn this off. +.lp +The areas in which sendmail is not ``unconditionally compliant'' are: +.ip \(sc5.2.6 +Sendmail does do header munging. +.ip \(sc5.2.10 +Sendmail doesn't always use the exact SMTP message +text from RFC 821. This is a rather silly requirement. +.ip \(sc5.3.1.1 +Sendmail doesn't guarantee only one connect for each +host on queue runs. Connection caching gives you most +of this, but it does not provide a guarantee. +.ip \(sc5.3.1.1 +Sendmail doesn't always provide an adequate limit +on concurrency. That is, there can be several +independent sendmails running at once. My feeling +is that doing an absolute limit would be a mistake +(it might result in lost mail). However, if you use +the XLA contributed software, most of this will be +guaranteed (but I don't guarantee the guarantee). +.sh 2 "Extended SMTP Support +.pp +Version 8 includes both sending and receiving support for Extended +SMTP support as defined by RFC 1425 (basic) and RFC 1427 (SIZE); +and limited support for RFC 1426 (BODY). +The body support is minimal because the +.q 8BITMIME +body type is not currently advertised. +Although such a body type will be accepted, +it will not be correctly converted to 7 bits +if speaking to a non-8-bit-MIME aware SMTP server. +.pp +.i Sendmail +tries to speak ESMTP if you have the `a' flag set +in the flags for the mailer descriptor, +or if the other end advertises the fact that it speaks ESMTP. +This is a non-standard advertisement: +.i sendmail +announces +.q "ESMTP spoken here" +during the initial connection message, +and client sendmails search for this message. +This creates some problems for some PC-based mailers, +which do not understand two-line greeting messages +as required by RFC 821. +.sh 2 "Eight-Bit Clean +.pp +Previous versions of sendmail used the 0200 bit for quoting. This +version avoids that use. +However, you can set option `7' to get seven bit stripping +for compatibility with RFC 821, +which is a 7-bit protocol. +This option says ``strip to 7 bits on input''. +.pp +Individual mailers can still produce seven bit out put using the +`7' mailer flag. +This flag says ``strip to 7 bits on output''. +.sh 2 "User Database" +.pp +The User Database (UDB) is an as-yet experimental attempt to provide +unified large-site name support. +We are installing it at Berkeley; +future versions may show significant modifications. +Briefly, UDB contains a database that is intended to contain +all the per-user information for your workgroup, +such as people's full names, their .plan information, +their outgoing mail name, and their mail drop. +.pp +The user database allows you to map both incoming and outgoing +addresses, much like IDA. However, the interface is still +better with IDA; +in particular, the alias file with incoming/outgoing marks +provides better locality of information. +.sh 2 "Improved BIND Support" +.pp +The BIND support, particularly for MX records, had a number of +annoying ``features'' which have been removed in this release. In +particular, these more tightly bind (pun intended) the name server +to sendmail, so that the name server resolution rules are incorporated +directly into sendmail. +.pp +The major change has been that the $[ ... $] operator didn't fully +qualify names that were in DNS as A or MX records. Version 8 does +this qualification. +.pp +This has proven to be an annoyance in Sun shops, +who often still run without BIND support. +However, it is really critical that this be supported, +since MX records are mandatory. +In SunOS you can choose either MX support or NIS support, +but not both. +This is fixed in Solaris, +and some +.i sendmail +support to allow this in SunOS should be forthcoming in a future release. +.sh 2 "Keyed Files" +.pp +Generalized keyed files is an idea taken directly from IDA sendmail +(albeit with a completely different implementation). +They can be useful on large sites. +.pp +Version 8 includes the following built-in map classes: +.ip dbm +Support for the ndbm(3) library. +.ip hash +Support for the ``Hash'' type from the new Berkeley db(3) library. +this library provides substantially better database support +than ndbm(3), +including in-memory caching, +arbitrarily long keys and values, +and better disk utilization. +.ip btree +Support for the ``B-Tree'' type from the new Berkeley db(3) library. +B-Trees provide better clustering than Hashed files +if you are fetching lots of records that have similar keys, +such as searching a dictionary for words beginning with ``detr''. +.ip nis +Support for NIS (a.k.a. YP) maps. +NIS+ is not supported in this version. +.ip host +Support for DNS lookups. +.ip dequote +A ``pseudo-map'' (that is, once that does not have any external data) +that allows a configuration file to break apart a quoted string +in the address. +This is necessary primarily for DECnet addresses, +which often have quoted addresses that need to be unwrapped on gateways. +.sh 2 "Multi-Word Classes & Macros in Classes" +.pp +Classes can now be multiple words. For example, +.(b +CShofmann.CS.Berkeley.EDU +.)b +allows you to match the entire string ``hofmann.CS.Berkeley.EDU'' +using the single construct ``$=S''. +.pp +Class definitions are now allowed to include macros \*- for example: +.(b +Cw$k +.)b +is legal. +.sh 2 "IDENT Protocol Support" +.pp +The IDENT protocol as defined in RFC 1413 [RFC1413] is supported. +However, many systems have a TCP/IP bug that renders this useless, +and the feature must be turned off. +Roughly, if one of these system receives a +.q "No route to host" +message (ICMP message ICMP_UNREACH_HOST) on +.i any +connection, all connections to that host are closed. +Some firewalls return this error if you try to connect +to the IDENT port, +so you can't receive email from these hosts on these systems. +It's possible that if the firewall used a more specific message +(such as ICMP_UNREACH_PROTOCOL, ICMP_UNREACH_PORT or ICMP_UNREACH_NET_PROHIB) +it would work, but this hasn't been verified. +.pp +IDENT protocol support cannot be used on +4.3BSD, +Apollo DomainOS, +Apple A/UX, +ConvexOS, +Data General DG/UX, +HP-UX, +Sequent Dynix, +or +Ultrix 4.x, x \(<= 3. +It seems to work on +4.4BSD, +IBM AIX 3.x, +OSF/1, +SGI IRIX, +Solaris, +SunOS, +and Ultrix 4.4. +.sh 2 "Separate Envelope/Header Processing +.pp +Since the From: line is passed in separately from the envelope +sender, these have both been made visible; the $g macro is set to +the envelope sender during processing of mailer argument vectors +and the header sender during processing of headers. +.pp +It is also possible to specify separate per-mailer envelope and +header processing. The SenderRWSet and RecipientRWset arguments +for mailers can be specified as ``envelope/header'' to give different +rewritings for envelope versus header addresses. +.sh 2 "Owner-List Propagates to Envelope +.pp +When an alias has an associated owner-list name, that alias is used +to change the envelope sender address. This will cause downstream +errors to be returned to that owner. +.pp +Some people find this confusing +because the envelope sender is what appears in the first +``From_'' line in UNIX messages +(that is, the line beginning ``From<space>'' +instead of ``From:''; +the latter is the header from, which +.i does +indicate the sender of the message). +In previous versions, +.i sendmail +has tried to avoid changing the envelope sender +for back compatibility with UNIX convention; +at this point that back compatibility is creating too many problems, +and it is necessary to move forward into the 1980s. +.sh 2 "Command Line Flags" +.pp +The +.b \-B +flag has been added to pass in body type information. +.pp +The +.b \-p +flag has been added to pass in protocol information +that was previously passed in by defining the +.b $r +and +.b $s +macros. +.pp +The +.b \-X +flag has been added to allow logging of all protocol in and +out of sendmail for debugging. +You can set +.q "\-X filename" +and a complete transcript will be logged in that file. +This gets big fast: the option is only for debugging. +.pp +The +.b \-q +flag can limit limit a queue run to specific recipients, +senders, or queue ids using \-qRsubstring, \-qSsubstring, or +\-qIsubstring respectively. +.sh 2 "New Configuration Line Types +.pp +The `T' (Trusted users) configuration line has been deleted. It +will still be accepted but will be ignored. +.pp +The `K' line has been added to declare database maps. +.pp +The `V' line has been added to declare the configuration version +level. +.pp +The `M' (mailer) line takes a D= field to specify execution +directory. +.sh 2 "New and Extended Options" +.pp +Several new options have been added, many to support new features, +others to allow tuning that was previously available only by +recompiling. Briefly: +.nr ii 0.5i +.ip A +The alias file specification can now be a list of alias files. +Also, the configuration can specify a class of file. +For example, to search the NIS aliases, use +.q OAnis:mail.aliases . +.ip b +Insist on a minimum number of disk blocks. +.ip C +Delivery checkpoint interval. Checkpoint the queue (to avoid +duplicate deliveries) every C addresses. +.ip E +Default error message. This message (or the contents of the +indicated file) are prepended to error messages. +.ip G +Enable GECOS matching. If you can't find a local user name +and this option is enabled, do a sequential scan of the passwd +file to match against full names. Previously a compile option. +.ip h +Maximum hop count. Previously this was compiled in. +.ip I +This option has been extended to allow setting of resolver parameters. +.ip j +Send errors in MIME-encapsulated format. +.ip J +Forward file path. Where to search for .forward files \*- defaults +to $HOME/.forward. +.ip k +Connection cache size. The total number of connections that will +be kept open at any time. +.ip K +Connection cache lifetime. The amount of time any connection +will be permitted to sit idle. +.ip l +Enable Errors-To: header. These headers violate RFC 1123; +this option is included to provide back compatibility with +old versions of sendmail. +.ip O +Incoming daemon options (e.g., use alternate SMTP port). +.ip p +Privacy options. These can be used to make your SMTP server +less friendly. +.ip r +This option has been extended to allow finer grained control +over timeouts. +For example, you can set the timeout for SMTP commands individually. +.ip R +Don't prune route-addrs. Normally, if version 8 sees an address +like "<@hostA,@hostB:user@hostC>, sendmail will try to strip off +as much as it can (up to user@hostC) as suggested by RFC 1123. +This option disables that behaviour. +.ip T +The +.q "Return To Sender" +timeout has been extended +to allow specification of a warning message interval, +typically something on the order of four hours. +If a message cannot be delivered in that interval, +a warning message is sent back to the sender +but the message continues to be tried. +.ip U +User database spec. This is still experimental. +.ip V +Fallback ``MX'' host. This can be thought of as an MX host +that applies to all addresses that has a very high preference +value (that is, use it only if everything else fails). +.ip w +If set, assume that if you are the best MX host for a host, +you should send directly to that host. This is intended +for compatibility with UIUC sendmail, and may have some +use on firewalls. +.ip 7 +Do not run eight bit clean. Technically, you have to assert +this option to be RFC 821 compatible. +.sh 2 "New Mailer Definitions" +.ip L= +Set the allowable line length. In V5, the L mailer flag implied +a line length limit of 990 characters; this is now settable to +an arbitrary value. +.ip F=a +Try to use ESMTP. It will fall back to SMTP if the initial +EHLO packet is rejected. +.ip F=b +Ensure a blank line at the end of messages. Useful on the +*file* mailer. +.ip F=c +Strip all comments from addresses; this should only be used as +a last resort when dealing with cranky mailers. +.ip F=g +Never use the null sender as the envelope sender, even when +running SMTP. This violates RFC 1123. +.ip F=7 +Strip all output to this mailer to 7 bits. +.ip F=L +Used to set the line limit to 990 bytes for SMTP compatibility. +It now does that only if the L= keyletter is not specified. +This flag is obsolete and should not be used. +.sh 2 "New or Changed Pre-Defined Macros" +.ip $k +UUCP node name from uname(2). +.ip $m +Domain part of our full hostname. +.ip $_ +RFC 1413-provided sender address. +.ip $w +Previously was sometimes the full domain name, sometimes +just the first word. Now guaranteed to be the first word +of the domain name (i.e., the host name). +.ip $j +Previously had to be defined \*- it is now predefined to be +the full domain name, if that can be determined. That is, +it is equivalent to $w.$m. +.sh 2 "New and Changed Classes" +.ip $=k +Initialized to contain $k. +.ip $=w +Now includes +.q [1.2.3.4] +(where 1.2.3.4 is your IP address) +to allow the configuration file to recognize your own IP address. +.sh 2 "New Rewriting Tokens" +.pp +The +.b $& +construct has been adopted from IDA to defer macro evaluation. +Normally, macros in rulesets are bound when the rule is first parsed +during startup. +Some macros change during processing and are uninteresting during startup. +However, that macro can be referenced using +.q $&x +to defer the evaulation of +$x +until the rule is processed. +.pp +The tokens +.b $( +and +.b $) +have been added to allow specification of map rewriting. +.pp +Version 8 allows +.b $@ +on the Left Hand Side of an `R' line to match +zero tokens. +This is intended to be used to match the null input. +.sh 2 "Bigger Defaults +.pp +Version 8 allows up to 100 rulesets instead of 30. It is recommended +that rulesets 0\-9 be reserved for sendmail's dedicated use in future +releases. +.pp +The total number of MX records that can be used has been raised to +20. +.pp +The number of queued messages that can be handled at one time has +been raised from 600 to 1000. +.sh 2 "Different Default Tuning Parameters +.pp +Version 8 has changed the default parameters for tuning queue costs +to make the number of recipients more important than the size of +the message (for small messages). This is reasonable if you are +connected with reasonably fast links. +.sh 2 "Auto-Quoting in Addresses +.pp +Previously, the ``Full Name <email address>'' syntax would generate +incorrect protocol output if ``Full Name'' had special characters +such as dot. This version puts quotes around such names. +.sh 2 "Symbolic Names On Error Mailer +.pp +Several names have been built in to the $@ portion of the $#error +mailer. For example: +.(b +$#error $@NOHOST $: Host unknown +.)b +Prints the indicated message +and sets the exit status of +.i sendmail +to +.sm EX_NOHOST . +.sh 2 "New Built-In Mailers" +.pp +Two new mailers, *file* and *include*, are included to define options +when mailing to a file or a :include: file respectively. Previously +these were overloaded on the local mailer. +.sh 2 "SMTP VRFY Doesn't Expand +.pp +Previous versions of sendmail treated VRFY and EXPN the same. In +this version, VRFY doesn't expand aliases or follow .forward files. +.pp +As an optimization, if you run with your default delivery mode +being queue-only, the RCPT command will also not chase aliases and +\&.forward files. +It will chase them when it processes the queue. +This speeds up RCPT processing. +.sh 2 "[IPC] Mailers Allow Multiple Hosts +.pp +When an address resolves to a mailer that has ``[IPC]'' as its +``Path'', the $@ part (host name) can be a colon-separated list of +hosts instead of a single hostname. This asks sendmail to search +the list for the first entry that is available exactly as though +it were an MX record. The intent is to route internal traffic +through internal networks without publishing an MX record to the +net. MX expansion is still done on the individual items. +.sh 2 "Aliases Extended" +.pp +The implementation has been merged with maps. Among other things, +this supports multiple alias files and NIS-based aliases. For +example: +.(b +OA/etc/aliases,nis:mail.aliases +.)b +will search first the local database +.q /etc/aliases +followed by the NIS map + +.sh 2 "Portability and Security Enhancements +.pp +A number of internal changes have been made to enhance portability. +.pp +Several fixes have been made to increase the paranoia factor. +.pp +In particular, the permissions required for .forward and :include: +files have been tightened up considerably. V5 would pretty much +read any file it could get to as root, which exposed some security +holes. V8 insists that all directories leading up to the .forward +or :include: file be searchable ("x" permission) by the controlling +user" (defined below), that the file itself be readable by the +controlling user, and that .forward files be owned by the user +who is being forwarded to or root. +.pp +The "controlling user" is the user on whose behalf the mail is +being delivered. For example, if you mail to "user1" then the +controlling user for ~user1/.forward and any mailers invoked +by that .forward file, including :include: files. +.pp +Previously, anyone who had a home directory could create a .forward +could forward to a program. Now, sendmail checks to make sure +that they have an "approved shell", that is, a shell listed in +the /etc/shells file. +.sh 2 "Miscellaneous Fixes and Enhancements" +.pp +A number of small bugs having to do with things like backslash-escaped +quotes inside of comments have been fixed. +.pp +The fixed size limit on header lines +(such as +.q To: +and +.q Cc: ) +has been eliminated; +those buffers are dynamically allocated now. +.pp +Sendmail writes a /etc/sendmail.pid file with the current process id +and the current invocation flags. +.pp +Two people using the same program (e.g., submit) are considered +"different" so that duplicate elimination doesn't delete one of +them. For example, two people forwarding their email to +|submit will be treated as two recipients. +.pp +The mailstats program prints mailer names and gets the location of +the sendmail.st file from /etc/sendmail.cf. +.pp +Many minor bugs have been fixed, such as handling of backslashes +inside of quotes. +.pp +A hook has been added to allow rewriting of local addresses after +aliasing. +.sh 1 "FUTURE WORK" +.pp +The previous section describes +.i sendmail +as of version 8.6.6. +There is still much to be done. +Some high points are described below. +This list is by no means exhaustive. +.sh 2 "Full MIME Support" +.pp +Currently +.i sendmail +only supports seven bit MIME messages. +Although it can pass eight bit MIME messages, +it cannot advertise that fact because the standards say +that the mail agent must be able to do 8- to 7-bit conversion +to have full 8-bit support. +This requires far more extensive modification of the message body +than is currently supported. +.pp +The best way to do this would be to support the general concept +of an external +``message filter'' +that could do arbitrary modifications of the message. +This would allow MIME conversion as well as such things as +automatic encryption of messages sent over external links. +This is probably an extremely non-trivial change. +.sh 2 "Service Switch Abstraction" +.pp +Most modern systems include some concept of a +.q "service switch" +\*- for example, to look up host names you can try +DNS, NIS, NIS+, text tables, NetInfo, +or other services in some arbitrary order. +This is currently very clumsy in +.i sendmail , +with only limited control of the services provided. +.sh 2 "More Control of Local Addresses" +.pp +Currently some addresses are declared as +.q local +and are handled specially \*- +for example, they may have .forward files, +may be translated into program calls or file deliveries, +and so forth. +These should be broken out into separate flags +to allow the local system administrator +to have more fine-grained control over operations. +.sh 2 "More Run-Time Configuration Options" +.pp +There are many options that are configured at compile time, +such as the method of file locking +and the use of the IDENT protocol +[RFC1413]. +These should be transfered to run time +by adding new options. +.pp +Similarly, some options are currently overloaded, +that is, a single option controls more than one thing. +These should probably be broken out into separate options. +.pp +This implies that options will change from single characters +to words. +.sh 2 "More Configuration Control Over Errors" +.pp +Currently, +the configuration file can generate an error message during parsing. +However, +it cannot tweak other operations, +such as issuing a warning message to the system postmaster. +Similarly, +some errors should not be triggered if they are in aliases +during an alias file rebuild, +but should be triggered if that alias is actually used. +.sh 2 "Long Term Host State" +.pp +Currently, +.i sendmail +only remembers host status during a single queue run. +This should be converted to long term status +stored on disk +so it can be shared between instantiations of +.i sendmail . +Entries will have to be timestamped +so they can time out. +This will allow +.i sendmail +to implement exponential backoff on queue runs +on a per-host basis. +.sh 2 "Connection Control" +.pp +Modern networks have different types of connectivity +than the past. +In particular, the rising prominence of dialup IP +has created certain challenges for automated servers. +It is not uncommon to try to make a connection to a host +and have it fail, even though if you tried again it would succeed. +The connection management could be a bit cleverer +to try to adapt to such situations. +.sh 2 "Other Caching" +.pp +When you do an MX record lookup, +the name server automatically returns the IP addresses +of the associated MX servers. +This information is currently ignored, +and another query is done to get this information. +It should be cached to avoid excess name server traffic. +.sh 1 "REFERENCES" +.ip [Allman83a] +.q "Sendmail \*- An Internetwork Mail Router." +E.

+eric@Sendmail.ORG +.sp +Version 8.70 +.sp +For Sendmail Version 8.7 +.)l +.sp 2 +.pp +.i Sendmail +implements a general purpose internetwork mail routing facility +under the UNIX\(rg +operating system. +It is not tied to any one transport protocol \*- +its function may be likened to a crossbar switch, +relaying messages from one domain into another. +In the process, +it can do a limited amount of message header editing +to put the message into a format that is appropriate +for the receiving domain. +All of this is done under the control of a configuration file. +.pp +Due to the requirements of flexibility +for +.i sendmail , +the configuration file can seem somewhat unapproachable. +However, there are only a few basic configurations +for most sites, +for which standard configuration files have been supplied. +Most other configurations +can be built by adjusting an existing configuration files +incrementally. +.pp +.i Sendmail +is based on +RFC821 (Simple Mail Transport Protocol), +RFC822 (Internet Mail Format Protocol), +RFC1123 (Internet Host Requirements), +RFC1521 (MIME), +RFC1651 (SMTP Service Extensions), +and a series of as-yet-draft standards describing +Delivery Status Notifications (DSNs), +available from the internet drafts sites as +draft-ietf-notary-mime-delivery-\fIXX\fP.txt, +draft-ietf-notary-mime-report-\fIXX\fP.txt, +draft-ietf-notary-smtp-drpt-\fIXX\fP.txt, +and +draft-ietf-notary-status-\fIXX\fP.txt +(replace +.i XX +by the latest draft number). +However, since +.i sendmail +is designed to work in a wider world, +in many cases it can be configured to exceed these protocols. +These cases are described herein. +.pp +Although +.i sendmail +is intended to run +without the need for monitoring, +it has a number of features +that may be used to monitor or adjust the operation +under unusual circumstances. +These features are described. +.pp +Section one describes how to do a basic +.i sendmail +installation. +Section two +explains the day-to-day information you should know +to maintain your mail system. +If you have a relatively normal site, +these two sections should contain sufficient information +for you to install +.i sendmail +and keep it happy. +Section three +describes some parameters that may be safely tweaked. +Section four +has information regarding the command line arguments. +Section five +contains the nitty-gritty information about the configuration +file. +This section is for masochists +and people who must write their own configuration file. +Section six +describes configuration that can be done at compile time. +Section seven +gives a brief description of differences +in this version of +.i sendmail . +The appendixes give a brief +but detailed explanation of a number of features +not described in the rest of the paper. +.pp +.b WARNING: +Several major changes were introduced in version 8.7. +You should not attempt to use this document +for prior versions of +.i sendmail . +.bp 7 +.sh 1 "BASIC INSTALLATION" +.pp +There are two basic steps to installing +.i sendmail . +The hard part is to build the configuration table. +This is a file that +.i sendmail +reads when it starts up +that describes the mailers it knows about, +how to parse addresses, +how to rewrite the message header, +and the settings of various options. +Although the configuration table is quite complex, +a configuration can usually be built +by adjusting an existing off-the-shelf configuration. +The second part is actually doing the installation, +i.e., creating the necessary files, etc. +.pp +The remainder of this section will describe the installation of +.i sendmail +assuming you can use one of the existing configurations +and that the standard installation parameters are acceptable. +All pathnames and examples +are given from the root of the +.i sendmail +subtree, +normally +.i /usr/src/usr.\*(SD/sendmail +on 4.4BSD. +.pp +If you are loading this off the tape, +continue with the next section. +If you have a running binary already on your system, +you should probably skip to section 1.2. +.sh 2 "Compiling Sendmail" +.pp +All +.i sendmail +source is in the +.i src +subdirectory. +If you are running on a 4.4BSD system, +compile by typing +.q make . +On other systems, you may have to make some other adjustments. +On most systems, +you can do the appropriate compilation by typing +.(b +sh makesendmail +.)b +This will leave the binary in an appropriately named subdirectory. +It works for multiple object versions +compiled out of the same directory. +.sh 3 "Tweaking the Makefile" +.pp +.i Sendmail +supports two different formats +for the local (on disk) version of databases, +notably the +.i aliases +database. +At least one of these should be defined if at all possible. +.nr ii 1i +.ip NDBM +The ``new DBM'' format, +available on nearly all systems around today. +This was the preferred format prior to 4.4BSD. +It allows such complex things as multiple databases +and closing a currently open database. +.ip NEWDB +The new database package from Berkeley. +If you have this, use it. +It allows +long records, +multiple open databases, +real in-memory caching, +and so forth. +You can define this in conjunction with one of the other two; +if you do, +old databases are read, +but when a new database is created it will be in NEWDB format. +As a nasty hack, +if you have NEWDB, NDBM, and NIS defined, +and if the alias file name includes the substring +.q /yp/ , +.i sendmail +will create both new and old versions of the alias file +during a +.i newalias +command. +This is required because the Sun NIS/YP system +reads the DBM version of the alias file. +It's ugly as sin, +but it works. +.lp +If neither of these are defined, +.i sendmail +reads the alias file into memory on every invocation. +This can be slow and should be avoided. +There are also several methods for remote database access: +.ip NIS +Sun's Network Information Services (formerly YP). +.ip NISPLUS +Sun's NIS+ services. +.ip NETINFO +NeXT's NetInfo service. +.ip HESIOD +Hesiod service (from Athena). +.lp +Other compilation flags are set in conf.h +and should be predefined for you +unless you are porting to a new environment. +.sh 3 "Compilation and installation" +.pp +After making the local system configuration described above, +You should be able to compile and install the system. +The script +.q makesendmail +is the best approach on most systems: +.(b +sh makesendmail +.)b +This will use +.i uname (1) +to select the correct Makefile for your environment. +.pp +You may be able to install using +.(b +sh makesendmail install +.)b +This should install the binary in +/usr/\*(SD +and create links from +/usr/\*(SB/newaliases +and +/usr/\*(SB/mailq +to +/usr/\*(SD/sendmail. +On 4.4BSD systems it will also format and install man pages. +.sh 2 "Configuration Files" +.pp +.i Sendmail +cannot operate without a configuration file. +The configuration defines the mail delivery mechanisms understood at this site, +how to access them, +how to forward email to remote mail systems, +and a number of tuning parameters. +This configuration file is detailed +in the later portion of this document. +.pp +The +.i sendmail +configuration can be daunting at first. +The world is complex, +and the mail configuration reflects that. +The distribution includes an m4-based configuration package +that hides a lot of the complexity. +.pp +These configuration files are simpler than old versions +largely because the world has become simpler; +in particular, +text-based host files are officially eliminated, +obviating the need to +.q hide +hosts behind a registered internet gateway. +.pp +These files also assume that most of your neighbors +use domain-based UUCP addressing; +that is, +instead of naming hosts as +.q host!user +they will use +.q host.domain!user . +The configuration files can be customized to work around this, +but it is more complex. +.pp +Our configuration files are processed by +.i m4 +to facilitate local customization; +the directory +.i cf +of the +.i sendmail +distribution directory +contains the source files. +This directory contains several subdirectories: +.nr ii 1i +.ip cf +Both site-dependent and site-independent descriptions of hosts. +These can be literal host names +(e.g., +.q ucbvax.mc ) +when the hosts are gateways +or more general descriptions +(such as +.q "tcpproto.mc" +as a general description of an SMTP-connected host +or +.q "uucpproto.mc" +as a general description of a UUCP-connected host). +Files ending +.b \&.mc +(``Master Configuration'') +are the input descriptions; +the output is in the corresponding +.b \&.cf +file. +The general structure of these files is described below. +.ip domain +Site-dependent subdomain descriptions. +These are tied to the way your organization wants to do addressing. +For example, +.b domain/cs.exposed.m4 +is our description for hosts in the CS.Berkeley.EDU subdomain +that want their individual hostname to be externally visible; +.b domain/cs.hidden.m4 +is the same except that the hostname is hidden +(everything looks like it comes from CS.Berkeley.EDU). +These are referenced using the +.sm DOMAIN +.b m4 +macro in the +.b \&.mc +file. +.ip feature +Definitions of specific features that some particular host in your site +might want. +These are referenced using the +.sm FEATURE +.b m4 +macro. +An example feature is +use_cw_file +(which tells +.i sendmail +to read an /etc/sendmail.cw file on startup +to find the set of local names). +.ip hack +Local hacks, referenced using the +.sm HACK +.b m4 +macro. +Try to avoid these. +The point of having them here is to make it clear that they smell. +.ip m4 +Site-independent +.i m4 (1) +include files that have information common to all configuration files. +This can be thought of as a +.q #include +directory. +.ip mailer +Definitions of mailers, +referenced using the +.sm MAILER +.b m4 +macro. +The mailer types that are known in this distribution are +fax, +local, +smtp, +uucp, +and usenet. +For example, to include support for the UUCP-based mailers, +use +.q MAILER(uucp) . +.ip ostype +Definitions describing various operating system environments +(such as the location of support files). +These are referenced using the +.sm OSTYPE +.b m4 +macro. +.ip sh +Shell files used by the +.b m4 +build process. +You shouldn't have to mess with these. +.ip siteconfig +Local site configuration information, +such as UUCP connectivity. +They normally contain lists of site information, for example: +.(b +SITE(contessa) +SITE(hoptoad) +SITE(nkainc) +SITE(well) +.)b +They are referenced using the SITECONFIG macro: +.(b +SITECONFIG(site.config.file, name_of_site, X) +.)b +where +.i X +is the macro/class name to use. +It can be U +(indicating locally connected hosts) +or one of W, X, or Y +for up to three remote UUCP hubs. +.pp +If you are in a new domain +(e.g., a company), +you will probably want to create a +cf/domain +file for your domain. +This consists primarily of relay definitions: +for example, Berkeley's domain definition +defines relays for +BitNET, +CSNET, +and UUCP. +Of these, +only the UUCP relay is particularly specific +to Berkeley. +All of these are internet-style domain names. +Please check to make certain they are reasonable for your domain. +.pp +Subdomains at Berkeley are also represented in the +cf/domain +directory. +For example, +the domain +cs-exposed +is the Computer Science subdomain with the local hostname shown +to other users; +cs-hidden +makes users appear to be from the CS.Berkeley.EDU subdomain +(with no local host information included). +You will probably have to update this directory +to be appropriate for your domain. +.pp +You will have to use or create +.b \&.mc +files in the +.i cf/cf +subdirectory for your hosts. +This is detailed in the +cf/README +file. +.sh 2 "Details of Installation Files" +.pp +This subsection describes the files that +comprise the +.i sendmail +installation. +.sh 3 "/usr/\*(SD/sendmail" +.pp +The binary for +.i sendmail +is located in /usr/\*(SD\**. +.(f +\**This is usually +/usr/sbin +on 4.4BSD and newer systems; +many systems install it in +/usr/lib. +I understand it is in /usr/ucblib +on System V Release 4. +.)f +It should be setuid root. +For security reasons, +/, /usr, and /usr/\*(SD +should be owned by root, mode 755\**. +.(f +\**Some vendors ship them owned by bin; +this creates a security hole that is not actually related to +.i sendmail . +Other important directories that should have restrictive ownerships +and permissions are +/bin, /usr/bin, /etc, /usr/etc, /lib, and /usr/lib. +.)f +.sh 3 "/etc/sendmail.cf" +.pp +This is the configuration file for +.i sendmail \**. +.(f +\**Actually, the pathname varies depending on the operating system; +/etc is the preferred directory. +Some older systems install it in +.b /usr/lib/sendmail.cf , +and I've also seen it in +.b /usr/ucblib +and +.b /etc/mail . +If you want to move this file, +change +.i src/conf.h . +.)f +This and /etc/sendmail.pid +are the only non-library file names compiled into +.i sendmail \**. +.(f +\**The system libraries can reference other files; +in particular, system library subroutines that +.i sendmail +calls probably reference +.i /etc/passwd +and +.i /etc/resolv.conf . +.)f +.pp +The configuration file is normally created +using the distribution files described above. +If you have a particularly unusual system configuration +you may need to create a special version. +The format of this file is detailed in later sections +of this document. +.sh 3 "/usr/\*(SB/newaliases" +.pp +The +.i newaliases +command should just be a link to +.i sendmail : +.(b +rm \-f /usr/\*(SB/newaliases +ln \-s /usr/\*(SD/sendmail /usr/\*(SB/newaliases +.)b +This can be installed in whatever search path you prefer +for your system. +.sh 3 "/var/spool/mqueue" +.pp +The directory +.i /var/spool/mqueue +should be created to hold the mail queue. +This directory should be mode 700 +and owned by root. +.pp +The actual path of this directory +is defined in the +.b Q +option of the +.i sendmail.cf +file. +.sh 3 "/etc/aliases*" +.pp +The system aliases are held in +.q /etc/aliases . +A sample is given in +.q lib/aliases +which includes some aliases which +.i must +be defined: +.(b +cp lib/aliases /etc/aliases +.i "edit /etc/aliases" +.)b +You should extend this file with any aliases that are apropos to your system. +.pp +Normally +.i sendmail +looks at a version of these files maintained by the +.i dbm \|(3) +or +.i db \|(3) +routines. +These are stored either in +.q /etc/aliases.dir +and +.q /etc/aliases.pag +or +.q /etc/aliases.db +depending on which database package you are using. +These can initially be created as empty files, +but they will have to be initialized promptly. +These should be mode 644: +.(b +cp /dev/null /etc/aliases.dir +cp /dev/null /etc/aliases.pag +chmod 644 /etc/aliases.* +newaliases +.)b +The +.i db +routines preset the mode reasonably, +so this step can be skipped. +The actual path of this file +is defined in the +.b A +option of the +.i sendmail.cf +file. +.sh 3 "/etc/rc" +.pp +It will be necessary to start up the +.i sendmail +daemon when your system reboots. +This daemon performs two functions: +it listens on the SMTP socket for connections +(to receive mail from a remote system) +and it processes the queue periodically +to insure that mail gets delivered when hosts come up. +.pp +Add the following lines to +.q /etc/rc +(or +.q /etc/rc.local +as appropriate) +in the area where it is starting up the daemons: +.(b +if [ \-f /usr/\*(SD/sendmail \-a \-f /etc/sendmail.cf ]; then + (cd /var/spool/mqueue; rm \-f [lnx]f*) + /usr/\*(SD/sendmail \-bd \-q30m & + echo \-n ' sendmail' >/dev/console +fi +.)b +The +.q cd +and +.q rm +commands insure that all lock files have been removed; +extraneous lock files may be left around +if the system goes down in the middle of processing a message. +The line that actually invokes +.i sendmail +has two flags: +.q \-bd +causes it to listen on the SMTP port, +and +.q \-q30m +causes it to run the queue every half hour. +.pp +Some people use a more complex startup script, +removing zero length qf files and df files for which there is no qf file. +For example, see Figure 1 +for an example of a complex startup script. +.(z +.hl +# remove zero length qf files +for qffile in qf* +do + if [ \-r $qffile ] + then + if [ ! \-s $qffile ] + then + echo \-n " <zero: $qffile>" > /dev/console + rm \-f $qffile + fi + fi +done +# rename tf files to be qf if the qf does not exist +for tffile in tf* +do +

the +.b \-bd +flag. +.sh 3 "/usr/lib/sendmail.hf" +.pp +This is the help file used by the SMTP +.b HELP +command. +It should be copied from +.q lib/sendmail.hf : +.(b +cp lib/sendmail.hf /usr/lib +.)b +The actual path of this file +is defined in the +.b H +option of the +.i sendmail.cf +file. +.sh 3 "/etc/sendmail.st" +.pp +If you wish to collect statistics +about your mail traffic, +you should create the file +.q /etc/sendmail.st : +.(b +cp /dev/null /etc/sendmail.st +chmod 666 /etc/sendmail.st +.)b +This file does not grow. +It is printed with the program +.q mailstats/mailstats.c. +The actual path of this file +is defined in the +.b S +option of the +.i sendmail.cf +file. +.sh 3 "/usr/\*(SB/mailq" +.pp +If +.i sendmail +is invoked as +.q mailq, +it will simulate the +.b \-bp +flag +(i.e., +.i sendmail +will print the contents of the mail queue; +see below). +This should be a link to /usr/\*(SD/sendmail. +.sh 1 "NORMAL OPERATIONS" +.sh 2 "The System Log" +.pp +The system log is supported by the +.i syslogd \|(8) +program. +All messages from +.i sendmail +are logged under the +.sm LOG_MAIL +facility\**. +.(f +\**Except on Ultrix, +which does not support facilities in the syslog. +.)f +.sh 3 "Format" +.pp +Each line in the system log +consists of a timestamp, +the name of the machine that generated it +(for logging from several machines +over the local area network), +the word +.q sendmail: , +and a message\**. +.(f +\**This format may vary slightly if your vendor has changed +the syntax. +.)f +Most messages are a sequence of +.i name \c +=\c +.i value +pairs. +.pp +The two most common lines are logged when a message is processed. +The first logs the receipt of a message; +there will be exactly one of these per message. +Some fields may be omitted if they do not contain interesting information. +Fields are: +.ip from +The envelope sender address. +.ip size +The size of the message in bytes. +.ip class +The class (i.e., numeric precedence) of the message. +.ip pri +The initial message priority (used for queue sorting). +.ip nrcpts +The number of envelope recipients for this message +(after aliasing and forwarding). +.ip msgid +The message id of the message (from the header). +.ip proto +The protocol used to receive this message (e.g., ESMTP or UUCP) +.ip relay +The machine from which it was received. +.lp +There is also one line logged per delivery attempt +(so there can be several per message if delivery is deferred +or there are multiple recipients). +Fields are: +.ip to +A comma-separated list of the recipients to this mailer. +.ip ctladdr +The ``controlling user'', that is, the name of the user +whose credentials we use for delivery. +.ip delay +The total delay between the time this message was received +and the time it was delivered. +.ip xdelay +The amount of time needed in this delivery attempt +(normally indicative of the speed of the connection). +.ip mailer +The name of the mailer used to deliver to this recipient. +.ip relay +The name of the host that actually accepted (or rejected) this recipient. +.ip stat +The delivery status. +.lp +Not all fields are present in all messages; +for example, the relay is not listed for local deliveries. +.sh 3 "Levels" +.pp +If you have +.i syslogd \|(8) +or an equivalent installed, +you will be able to do logging. +There is a large amount of information that can be logged. +The log is arranged as a succession of levels. +At the lowest level +only extremely strange situations are logged. +At the highest level, +even the most mundane and uninteresting events +are recorded for posterity. +As a convention, +log levels under ten +are considered generally +.q useful; +log levels above 64 +are reserved for debugging purposes. +Levels from 11\-64 are reserved for verbose information +that some sites might want. +.pp +A complete description of the log levels +is given in section +.\" XREF +4.6. +.sh 2 "Dumping State" +.pp +You can ask +.i sendmail +to log a dump of the open files +and the connection cache +by sending it a +.sm SIGUSR1 +signal. +The results are logged at +.sm LOG_DEBUG +priority. +.sh 2 "The Mail Queue" +.pp +Sometimes a host cannot handle a message immediately. +For example, it may be down or overloaded, causing it to refuse connections. +The sending host is then expected to save this message in +its mail queue +and attempt to deliver it later. +.pp +Under normal conditions the mail queue will be processed transparently. +However, you may find that manual intervention is sometimes necessary. +For example, +if a major host is down for a period of time +the queue may become clogged. +Although +.i sendmail +ought to recover gracefully when the host comes up, +you may find performance unacceptably bad in the meantime. +.sh 3 "Printing the queue" +.pp +The contents of the queue can be printed +using the +.i mailq +command +(or by specifying the +.b \-bp +flag to +.i sendmail ): +.(b +mailq +.)b +This will produce a listing of the queue id's, +the size of the message, +the date the message entered the queue, +and the sender and recipients. +.sh 3 "Forcing the queue" +.pp +.i Sendmail +should run the queue automatically +at intervals. +The algorithm is to read and sort the queue, +and then to attempt to process all jobs in order. +When it attempts to run the job, +.i sendmail +first checks to see if the job is locked. +If so, it ignores the job. +.pp +There is no attempt to insure that only one queue processor +exists at any time, +since there is no guarantee that a job cannot take forever +to process +(however, +.i sendmail +does include heuristics to try to abort jobs +that are taking absurd amounts of time; +technically, this violates RFC 821, but is blessed by RFC 1123). +Due to the locking algorithm, +it is impossible for one job to freeze the entire queue. +However, +an uncooperative recipient host +or a program recipient +that never returns +can accumulate many processes in your system. +Unfortunately, +there is no completely general way to solve this. +.pp +In some cases, +you may find that a major host going down +for a couple of days +may create a prohibitively large queue. +This will result in +.i sendmail +spending an inordinate amount of time +sorting the queue. +This situation can be fixed by moving the queue to a temporary place +and creating a new queue. +The old queue can be run later when the offending host returns to service. +.pp +To do this, +it is acceptable to move the entire queue directory: +.(b +cd /var/spool +mv mqueue omqueue; mkdir mqueue; chmod 700 mqueue +.)b +You should then kill the existing daemon +(since it will still be processing in the old queue directory) +and create a new daemon. +.pp +To run the old mail queue, +run the following command: +.(b +/usr/\*(SD/sendmail \-oQ/var/spool/omqueue \-q +.)b +The +.b \-oQ +flag specifies an alternate queue directory +and the +.b \-q +flag says to just run every job in the queue. +If you have a tendency toward voyeurism, +you can use the +.b \-v +flag to watch what is going on. +.pp +When the queue is finally emptied, +you can remove the directory: +.(b +rmdir /var/spool/omqueue +.)b +.sh 2 "The Service Switch" +.pp +The implementation of certain system services +such as host and user name lookup +is controlled by the service switch. +If the host operating system supports such a switch +.i sendmail +will use the native version. +Ultrix, Solaris, and DEC OSF/1 are examples of such systems. +.pp +If the underlying operating system does not support a service switch +(e.g., SunOS, HP-UX, BSD) +then +.i sendmail +will provide a stub implementation. +The +.b ServiceSwitchFile +option points to the name of a file that has the service definitions +Each line has the name of a service +and the possible implementations of that service. +For example, the file: +.(b +hosts dns files nis +aliases files nis +.)b +will ask +.i sendmail +to look for hosts in the Domain Name System first. +If the requested host name is not found, +it tries local files, +and if that fails it tries NIS. +Similarly, +when looking for aliases +it will try the local files first +followed by NIS. +.pp +Service switches are not completely integrated. +For example, despite the fact that the host entry listed in the above example +specifies to look in NIS, +on SunOS this won't happen because the system implementation of +.i gethostbyname \|(3) +doesn't understand this. +If there is enough demand +.i sendmail +may reimplement +.i gethostbyname \|(3), +.i gethostbyaddr \|(3), +.i getpwent \|(3), +and the other system routines that would be necessary +to make this work seamlessly. +.sh 2 "The Alias Database" +.pp +The alias database exists in two forms. +One is a text form, +maintained in the file +.i /etc/aliases. +The aliases are of the form +.(b +name: name1, name2, ... +.)b +Only local names may be aliased; +e.g., +.(b +eric@prep.ai.MIT.EDU: eric@CS.Berkeley.EDU +.)b +will not have the desired effect +(except on prep.ai.MIT.EDU, +and they probably don't want me)\**. +.(f +\**Actually, any mailer that has the `A' mailer flag set +will permit aliasing; +this is normally limited to the local mailer. +.)f +Aliases may be continued by starting any continuation lines +with a space or a tab. +Blank lines and lines beginning with a sharp sign +(\c +.q # ) +are comments. +.pp +The second form is processed by the +.i ndbm \|(3)\** +.(f +\**The +.i gdbm +package probably works as well. +.)f +or +.i db \|(3) +library. +This form is in the files +.i /etc/aliases.dir +and +.i /etc/aliases.pag. +This is the form that +.i sendmail +actually uses to resolve aliases. +This technique is used to improve performance. +.pp +The control of search order is actually set by the service switch. +Essentially, the entry +.(b +OAswitch:aliases +.)b +is always added as the first alias entry; +also, the first alias file name without a class +(e.g., without +.q nis: +on the front) +will be used as the name of the file for a ``files'' entry +in the aliases switch. +For example, if the configuration file contains +.(b +OA/etc/aliases +.)b +and the service switch contains +.(b +aliases nis files nisplus +.)b +then aliases will first be searched in the NIS database, +then in /etc/aliases, +then in the NIS+ database. +.pp +You can also use +.sm NIS -based +alias files. +For example, the specification: +.(b +OA/etc/aliases +OAnis:mail.aliases@my.nis.domain +.)b +will first search the /etc/aliases file +and then the map named +.q mail.aliases +in +.q my.nis.domain . +Warning: if you build your own +.sm NIS -based +alias files, +be sure to provide the +.b \-l +flag to +.i makedbm (8) +to map upper case letters in the keys to lower case; +otherwise, aliases with upper case letters in their names +won't match incoming addresses. +.pp +Additional flags can be added after the colon +exactly like a +.b K +line \(em for example: +.(b +OAnis:\-N mail.aliases@my.nis.domain +.)b +will search the appropriate NIS map and always include null bytes in the key. +.sh 3 "Rebuilding the alias database" +.pp +The DB or DBM version of the database +may be rebuilt explicitly by executing the command +.(b +newaliases +.)b +This is equivalent to giving +.i sendmail +the +.b \-bi +flag: +.(b +/usr/\*(SD/sendmail \-bi +.)b +.pp +If the +.b RebuildAliases +(old +.b D ) +option is specified in the configuration, +.i sendmail +will rebuild the alias database automatically +if possible +when it is out of date. +Auto-rebuild can be dangerous +on heavily loaded machines +with large alias files; +if it might take more than the rebuild timeout +(option +.b AliasWait , +old +.b a , +which is normally five minutes) +to rebuild the database, +there is a chance that several processes will start the rebuild process +simultaneously. +.pp +If you have multiple aliases databases specified, +the +.b \-bi +flag rebuilds all the database types it understands +(for example, it can rebuild NDBM databases but not NIS databases). +.sh 3 "Potential problems" +.pp +There are a number of problems that can occur +with the alias database. +They all result from a +.i sendmail +process accessing the DBM version +while it is only partially built. +This can happen under two circumstances: +One process accesses the database +while another process is rebuilding it, +or the process rebuilding the database dies +(due to being killed or a system crash) +before completing the rebuild. +.pp +Sendmail has three techniques to try to relieve these problems. +First, it ignores interrupts while rebuilding the database; +this avoids the problem of someone aborting the process +leaving a partially rebuilt database. +Second, +it locks the database source file during the rebuild \(em +but that may not work over NFS or if the file is unwritable. +Third, +at the end of the rebuild +it adds an alias of the form +.(b +@: @ +.)b +(which is not normally legal). +Before +.i sendmail +will access the database, +it checks to insure that this entry exists\**. +.(f +\**The +.b AliasWait +option is required in the configuration +for this action to occur. +This should normally be specified. +.)f +.sh 3 "List owners" +.pp +If an error occurs on sending to a certain address, +say +.q \fIx\fP , +.i sendmail +will look for an alias +of the form +.q owner-\fIx\fP +to receive the errors. +This is typically useful +for a mailing list +where the submitter of the list +has no control over the maintenance of the list itself; +in this case the list maintainer would be the owner of the list. +For example: +.(b +unix-wizards: eric@ucbarpa, wnj@monet, nosuchuser, + sam@matisse +owner-unix-wizards: unix-wizards-request +unix-wizards-request: eric@ucbarpa +.)b +would cause +.q eric@ucbarpa +to get the error that will occur +when someone sends to +unix-wizards +due to the inclusion of +.q nosuchuser +on the list. +.pp +List owners also cause the envelope sender address to be modified. +The contents of the owner alias are used if they point to a single user, +otherwise the name of the alias itself is used. +For this reason, and to obey Internet conventions, +the +.q owner- +address normally points at the +.q -request +address; this causes messages to go out with the typical Internet convention +of using ``\c +.i list -request'' +as the return address. +.sh 2 "User Information Database" +.pp +If you have a version of +.i sendmail +with the user information database +compiled in, +and you have specified one or more databases using the +.b U +option, +the databases will be searched for a +.i user :maildrop +entry. +If found, the mail will be sent to the specified address. +.sh 2 "Per-User Forwarding (.forward Files)" +.pp +As an alternative to the alias database, +any user may put a file with the name +.q .forward +in his or her home directory. +If this file exists, +.i sendmail +redirects mail for that user +to the list of addresses listed in the .forward file. +For example, if the home directory for user +.q mckusick +has a .forward file with contents: +.(b +mckusick@ernie +kirk@calder +.)b +then any mail arriving for +.q mckusick +will be redirected to the specified accounts. +.pp +Actually, the configuration file defines a sequence of filenames to check. +By default, this is the user's .forward file, +but can be defined to be more generally using the +.b J +option. +If you change this, +you will have to inform your user base of the change; +\&.forward is pretty well incorporated into the collective subconscious. +.sh 2 "Special Header Lines" +.pp +Several header lines have special interpretations +defined by the configuration file. +Others have interpretations built into +.i sendmail +that cannot be changed without changing the code. +These builtins are described here. +.sh 3 "Errors-To:" +.pp +If errors occur anywhere during processing, +this header will cause error messages to go to +the listed addresses. +This is intended for mailing lists. +.pp +The Errors-To: header was created in the bad old days +when UUCP didn't understand the distinction between an envelope and a header; +this was a hack to provide what should now be passed +as the envelope sender address. +It should go away. +It is only used if the +.b UseErrorsTo +option is set. +.pp +The Errors-To: header is official deprecated +and will go away in a future release. +.sh 3 "Apparently-To:" +.pp +RFC 822 requires at least one recipient field +(To:, Cc:, or Bcc: line) +in every message. +If a message comes in with no recipients listed in the message +then +.i sendmail +will adjust the header based on the +.q NoRecipientAction +option. +One of the possible actions is to add an +.q "Apparently-To:" +header line for any recipients it is aware of. +This is not put in as a standard recipient line +to warn any recipients that the list is not complete. +.pp +The Apparently-To: header is non-standard +and is deprecated. +.sh 3 "Precedence" +.pp +The Precedence: header can be used as a crude control of message priority. +It tweaks the sort order in the queue +and can be configured to change the message timeout values. +.sh 2 "IDENT Protocol Support" +.pp +.i Sendmail +supports the IDENT protocol as defined in RFC 1413. +Although this enhances identification +of the author of an email message +by doing a ``call back'' to the originating system to include +the owner of a particular TCP connection +in the audit trail +it is in no sense perfect; +a determined forger can easily spoof the IDENT protocol. +The following description is excerpted from RFC 1413: +.ba +5 +.lp +6. Security Considerations +.lp +The information returned by this protocol is at most as trustworthy +as the host providing it OR the organization operating the host. For +example, a PC in an open lab has few if any controls on it to prevent +a user from having this protocol return any identifier the user +wants. Likewise, if the host has been compromised the information +returned may be completely erroneous and misleading. +.lp +The Identification Protocol is not intended as an authorization or +access control protocol. At best, it provides some additional +auditing information with respect to TCP connections. At worst, it +can provide misleading, incorrect, or maliciously incorrect +information. +.lp +The use of the information returned by this protocol for other than +auditing is strongly discouraged. Specifically, using Identification +Protocol information to make access control decisions - either as the +primary method (i.e., no other checks) or as an adjunct to other +methods may result in a weakening of normal host security. +.lp +An Identification server may reveal information about users, +entities, objects or processes which might normally be considered +private. An Identification server provides service which is a rough +analog of the CallerID services provided by some phone companies and +many of the same privacy considerations and arguments that apply to +the CallerID service apply to Identification. If you wouldn't run a +"finger" server due to privacy considerations you may not want to run +this protocol. +.ba +.lp +In some cases your system may not work properly with IDENT support +due to a bug in the TCP/IP implementation. +The symptoms will be that for some hosts +the SMTP connection will be closed +almost immediately. +If this is true or if you do not want to use IDENT, +you should set the IDENT timeout to zero; +this will disable the IDENT protocol. +.sh 1 "ARGUMENTS" +.pp +The complete list of arguments to +.i sendmail +is described in detail in Appendix A. +Some important arguments are described here. +.sh 2 "Queue Interval" +.pp +The amount of time between forking a process +to run through the queue +is defined by the +.b \-q +flag. +If you run with delivery mode set to +.b i +or +.b b +this can be relatively large, +since it will only be relevant +when a host that was down comes back up. +If you run in +.b q +mode +it should be relatively short, +since it defines the maximum amount of time that a message +may sit in the queue. +(See also the MinQueueAge option.) +.pp +RFC 1123 section 5.3.1.1 says that this value should be at least 30 minutes +(although that probably doesn't make sense if you use ``queue-only'' mode). +.sh 2 "Daemon Mode" +.pp +If you allow incoming mail over an IPC connection, +you should have a daemon running. +This should be set by your +.i /etc/rc +file using the +.b \-bd +flag. +The +.b \-bd +flag and the +.b \-q +flag may be combined in one call: +.(b +/usr/\*(SD/sendmail \-bd \-q30m +.)b +.pp +An alternative approach is to invoke sendmail from +.i inetd (8) +(use the +.b \-bs +flag to ask sendmail to speak SMTP on its standard input and output). +This works and allows you to wrap +.i sendmail +in a TCP wrapper program, +but may be a bit slower since the configuration file +has to be re-read on every message that comes in. +If you do this, you still need to have a +.i sendmail +running to flush the queue: +.(b +/usr/\*(SD/sendmail \-q30m +.)b +.sh 2 "Forcing the Queue" +.pp +In some cases you may find that the queue has gotten clogged for some reason. +You can force a queue run +using the +.b \-q +flag (with no value). +It is entertaining to use the +.b \-v +flag (verbose) +when this is done to watch what happens: +.(b +/usr/\*(SD/sendmail \-q \-v +.)b +.pp +You can also limit the jobs to those with a particular queue identifier, +sender, or recipient +using one of the queue modifiers. +For example, +.q \-qRberkeley +restricts the queue run to jobs that have the string +.q berkeley +somewhere in one of the recipient addresses. +Similarly, +.q \-qSstring +limits the run to particular senders and +.q \-qIstring +limits it to particular queue identifiers. +.sh 2 "Debugging" +.pp +There are a fairly large number of debug flags +built into +.i sendmail . +Each debug flag has a number and a level, +where higher levels means to print out more information. +The convention is that levels greater than nine are +.q absurd, +i.e., +they print out so much information that you wouldn't normally +want to see them except for debugging that particular piece of code. +Debug flags are set using the +.b \-d +option; +the syntax is: +.(b +.ta \w'debug-option 'u +debug-flag: \fB\-d\fP debug-list +debug-list: debug-option [ , debug-option ]* +debug-option: debug-range [ . debug-level ] +debug-range: integer | integer \- integer +debug-level: integer +.)b +where spaces are for reading ease only. +For example, +.(b +\-d12 Set flag 12 to level 1 +\-d12.3 Set flag 12 to level 3 +\-d3\-17 Set flags 3 through 17 to level 1 +\-d3\-17.4 Set flags 3 through 17 to level 4 +.)b +For a complete list of the available debug flags +you will have to look at the code +(they are too dynamic to keep this documentation up to date). +.sh 2 "Changing the Values of Options" +.pp +Options can be overridden using the +.b \-o +or +.b \-O +command line flags. +For example, +.(b +/usr/\*(SD/sendmail \-oT2m +.)b +sets the +.b T +(timeout) option to two minutes +for this run only; +the equivalent line using the long option name is +.(b +/usr/\*(SD/sendmail -OQueueTimeout=2m +.)b +.pp +Some options have security implications. +Sendmail allows you to set these, +but relinquishes its setuid root permissions thereafter\**. +.(f +\**That is, it sets its effective uid to the real uid; +thus, if you are executing as root, +as from root's crontab file or during system startup +the root permissions will still be honored. +.)f +.sh 2 "Trying a Different Configuration File" +.pp +An alternative configuration file +can be specified using the +.b \-C +flag; for example, +.(b +/usr/\*(SD/sendmail \-Ctest.cf \-oQ/tmp/mqueue +.)b +uses the configuration file +.i test.cf +instead of the default +.i /etc/sendmail.cf. +If the +.b \-C +flag has no value +it defaults to +.i sendmail.cf +in the current directory. +.pp +.i Sendmail +gives up its setuid root permissions +when you use this flag, so it is common to use a publicly writable directory +(such as /tmp) +as the spool directory (QueueDirectory or Q option) while testing. +.sh 2 "Logging Traffic" +.pp +Many SMTP implementations do not fully implement the protocol. +For example, some personal computer based SMTPs +do not understand continuation lines in reply codes. +These can be very hard to trace. +If you suspect such a problem, you can set traffic logging using the +.b \-X +flag. +For example, +.(b +/usr/\*(SD/sendmail \-X /tmp/traffic \-bd +.)b +will log all traffic in the file +.i /tmp/traffic . +.pp +This logs a lot of data very quickly and should +.b NEVER +be used +during normal operations. +After starting up such a daemon, +force the errant implementation to send a message to your host. +All message traffic in and out of +.i sendmail , +including the incoming SMTP traffic, +will be logged in this file. +.sh 2 "Testing Configuration Files" +.pp +When you build a configuration table, +you can do a certain amount of testing +using the +.q "test mode" +of +.i sendmail . +For example, +you could invoke +.i sendmail +as: +.(b +sendmail \-bt \-Ctest.cf +.)b +which would read the configuration file +.q test.cf +and enter test mode. +In this mode, +you enter lines of the form: +.(b +rwset address +.)b +where +.i rwset +is the rewriting set you want to use +and +.i address +is an address to apply the set to. +Test mode shows you the steps it takes +as it proceeds, +finally showing you the address it ends up with. +You may use a comma separated list of rwsets +for sequential application of rules to an input. +For example: +.(b +3,1,21,4 monet:bollard +.)b +first applies ruleset three to the input +.q monet:bollard. +Ruleset one is then applied to the output of ruleset three, +followed similarly by rulesets twenty-one and four. +.pp +If you need more detail, +you can also use the +.q \-d21 +flag to turn on more debugging. +For example, +.(b +sendmail \-bt \-d21.99 +.)b +turns on an incredible amount of information; +a single word address +is probably going to print out several pages worth of information. +.pp +You should be warned that internally, +.i sendmail +applies ruleset 3 to all addresses. +In test mode +you will have to do that manually. +For example, older versions allowed you to use +.(b +0 bruce@broadcast.sony.com +.)b +This version requires that you use: +.(b +3,0 bruce@broadcast.sony.com +.)b +.pp +As of version 8.7, +some other syntaxes are available in test mode: +.bu +\&.D\|x\|value +defines macro +.i x +to have the indicated +.i value . +This is useful when debugging rules that use the +.b $& \c +.i x +syntax. +.bu +\&.C\|c\|value +adds the indicated +.i value +to class +.i c . +.bu +\&.S\|ruleset +dumps the contents of the indicated ruleset. +.bu +\-d\|debug-spec +is equivalent to the command-line flag. +.sh 1 "TUNING" +.pp +There are a number of configuration parameters +you may want to change, +depending on the requirements of your site. +Most of these are set +using an option in the configuration file. +For example, +the line +.q "O Timeout.queuereturn=5d" +sets option +.q Timeout.queuereturn +to the value +.q 5d +(five days). +.pp +Most of these options have appropriate defaults for most sites. +However, +sites having very high mail loads may find they need to tune them +as appropriate for their mail load. +In particular, +sites experiencing a large number of small messages, +many of which are delivered to many recipients, +may find that they need to adjust the parameters +dealing with queue priorities. +.pp +All versions of +.i sendmail +prior to 8.7 +had single character option names. +As of 8.7, +options have long (multi-character names). +Although old short names are still accepted, +most new options do not have short equivalents. +.pp +This section only describes the options you are most likely +to want to tweak; +read section +.\"XREF +5 +for more details. +.sh 2 "Timeouts" +.pp +All time intervals are set +using a scaled syntax. +For example, +.q 10m +represents ten minutes, whereas +.q 2h30m +represents two and a half hours. +The full set of scales is: +.(b +.ta 4n +s seconds +m minutes +h hours +d days +w weeks +.)b +.sh 3 "Queue interval" +.pp +The argument to the +.b \-q +flag +specifies how often a sub-daemon will run the queue. +This is typically set to between fifteen minutes +and one hour. +RFC 1123 section 5.3.1.1 recommends that this be at least 30 minutes. +.sh 3 "Read timeouts" +.pp +Timeouts all have option names +.q Timeout.\fIsuboption\fP . +The recognized +.i suboption s, +their default values, and the minimum values +allowed by RFC 1123 section 5.3.2 are: +.nr ii 1i +.ip connect +The time to wait for an SMTP connection to open +(the +.i connect (2) +system call) +[0, unspecified]. +If zero, uses the kernel default. +In no case can this option extend the timeout +longer than the kernel provides, but it can shorten it. +This is to get around kernels that provide an absurdly long connection timeout +(90 minutes in one case). +.ip initial +The wait for the initial 220 greeting message +[5m, 5m]. +.ip helo +The wait for a reply from a HELO or EHLO command +[5m, unspecified]. +This may require a host name lookup, so +five minutes is probably a reasonable minimum. +.ip mail\(dg +The wait for a reply from a MAIL command +[10m, 5m]. +.ip rcpt\(dg +The wait for a reply from a RCPT command +[1h, 5m]. +This should be long +because it could be pointing at a list +that takes a long time to expand +(see below). +.ip datainit\(dg +The wait for a reply from a DATA command +[5m, 2m]. +.ip datablock\(dg +The wait for reading a data block +(that is, the body of the message). +[1h, 3m]. +This should be long because it also applies to programs +piping input to +.i sendmail +which have no guarantee of promptness. +.ip datafinal\(dg +The wait for a reply from the dot terminating a message. +[1h, 10m]. +If this is shorter than the time actually needed +for the receiver to deliver the message, +duplicates will be generated. +This is discussed in RFC 1047. +.ip rset +The wait for a reply from a RSET command +[5m, unspecified]. +.ip quit +The wait for a reply from a QUIT command +[2m, unspecified]. +.ip misc +The wait for a reply from miscellaneous (but short) commands +such as NOOP (no-operation) and VERB (go into verbose mode). +[2m, unspecified]. +.ip command\(dg +In server SMTP, +the time to wait for another command. +[1h, 5m]. +.ip ident +The timeout waiting for a reply to an IDENT query +[30s\**, unspecified]. +.(f +\**On some systems the default is zero to turn the protocol off entirely. +.)f +.lp +For compatibility with old configuration files, +if no +.i suboption +is specified, +all the timeouts marked with \(dg are set to the indicated value. +.pp +Many of the RFC 1123 minimum values +may well be too short. +.i Sendmail +was designed to the RFC 822 protocols, +which did not specify read timeouts; +hence, versions of +.i sendmail +prior to version 8.1 did not guarantee to reply to messages promptly. +In particular, a +.q RCPT +command specifying a mailing list +will expand and verify the entire list; +a large list on a slow system +may easily take more than five minutes\**. +.(f +\**This verification includes looking up every address +with the name server; +this involves network delays, +and can in some cases can be considerable. +.)f +I recommend a one hour timeout \*- +since a communications failure during the RCPT phase is rare, +a long timeout is not onerous +and may ultimately help reduce network load +and duplicated messages. +.pp +For example, the lines: +.(b +O Timeout.command=25m +O Timeout.datablock=3h +.)b +sets the server SMTP command timeout to 25 minutes +and the input data block timeout to three hours. +.sh 3 "Message timeouts" +.pp +After sitting in the queue for a few days, +a message will time out. +This is to insure that at least the sender is aware +of the inability to send a message. +The timeout is typically set to five days. +It is sometimes considered convenient to also send a warning message +if the message is in the queue longer than a few hours +(assuming you normally have good connectivity; +if your messages normally took several hours to send +you wouldn't want to do this because it wouldn't be an unusual event). +These timeouts are set using the +.b Timeout.queuereturn +and +.b Timeout.queuewarn +options in the configuration file +(previously both were set using the +.b T +option). +.pp +Since these options are global, +and since you can not know +.i "a priori" +how long another host outside your domain will be down, +a five day timeout is recommended. +This allows a recipient to fix the problem even if it occurs +at the beginning of a long weekend. +RFC 1123 section 5.3.1.1 says that this parameter +should be ``at least 4\-5 days''. +.pp +The +.b Timeout.queuewarn +value can be piggybacked on the +.b T +option by indicating a time after which +a warning message should be sent; +the two timeouts are separated by a slash. +For example, the line +.(b +OT5d/4h +.)b +causes email to fail after five days, +but a warning message will be sent after four hours. +This should be large enough that the message will have been tried +several times. +.sh 2 "Forking During Queue Runs" +.pp +By setting the +.b ForkEachJob +(\c +.b Y ) +option, +.i sendmail +will fork before each individual message +while running the queue. +This will prevent +.i sendmail +from consuming large amounts of memory, +so it may be useful in memory-poor environments. +However, if the +.b ForkEachJob +option is not set, +.i sendmail +will keep track of hosts that are down during a queue run, +which can improve performance dramatically. +.pp +If the +.b ForkEachJob +option is set, +.i sendmail +can not use connection caching. +.sh 2 "Queue Priorities" +.pp +Every message is assigned a priority when it is first instantiated, +consisting of the message size (in bytes) +offset by the message class +(which is determined from the Precedence: header) +times the +.q "work class factor" +and the number of recipients times the +.q "work recipient factor." +The priority is used to order the queue. +Higher numbers for the priority mean that the message will be processed later +when running the queue. +.pp +The message size is included so that large messages are penalized +relative to small messages. +The message class allows users to send +.q "high priority" +messages by including a +.q Precedence: +field in their message; +the value of this field is looked up in the +.b P +lines of the configuration file. +Since the number of recipients affects the amount of load a message presents +to the system, +this is also included into the priority. +.pp +The recipient and class factors +can be set in the configuration file using the +.b RecipientFactor +(\c +.b y ) +and +.b ClassFactor +(\c +.b z ) +options respectively. +They default to 30000 (for the recipient factor) +and 1800 +(for the class factor). +The initial priority is: +.EQ +pri = msgsize - (class times bold ClassFactor) + (nrcpt times bold RecipientFactor) +.EN +(Remember, higher values for this parameter actually mean +that the job will be treated with lower priority.) +.pp +The priority of a job can also be adjusted each time it is processed +(that is, each time an attempt is made to deliver it) +using the +.q "work time factor," +set by the +.b RetryFactor +(\c +.b Z ) +option. +This is added to the priority, +so it normally decreases the precedence of the job, +on the grounds that jobs that have failed many times +will tend to fail again in the future. +The +.b RetryFactor +option defaults to 90000. +.sh 2 "Load Limiting" +.pp +.i Sendmail +can be asked to queue (but not deliver) +mail if the system load average gets too high +using the +.b QueueLA +(\c +.b x ) +option. +When the load average exceeds the value of the +.b QueueLA +option, +the delivery mode is set to +.b q +(queue only) +if the +.b QueueFactor +(\c +.b q ) +option divided by the difference in the current load average and the +.b QueueLA +option +plus one +exceeds the priority of the message \(em +that is, the message is queued iff: +.EQ +pri > { bold QueueFactor } over { LA - { bold QueueLA } + 1 } +.EN +The +.b QueueFactor +option defaults to 600000, +so each point of load average is worth 600000 +priority points +(as described above). +.pp +For drastic cases, +the +.b RefuseLA +(\c +.b X ) +option defines a load average at which +.i sendmail +will refuse +to accept network connections. +Locally generated mail +(including incoming UUCP mail) +is still accepted. +.sh 2 "Delivery Mode" +.pp +There are a number of delivery modes that +.i sendmail +can operate in, +set by the +.b DeliveryMode +(\c +.b d ) +configuration option. +These modes +specify how quickly mail will be delivered. +Legal modes are: +.(b +.ta 4n +i deliver interactively (synchronously) +b deliver in background (asynchronously) +q queue only (don't deliver) +d defer delvery attempts (don't deliver) +.)b +There are tradeoffs. +Mode +.q i +gives the sender the quickest feedback, +but may slow down some mailers and +is hardly ever necessary. +Mode +.q b +delivers promptly but +can cause large numbers of processes +if you have a mailer that takes a long time to deliver a message. +Mode +.q q +minimizes the load on your machine, +but means that delivery may be delayed for up to the queue interval. +Mode +.q d +is identical to mode +.q q +except that it also prevents all the early map lookups from working; +it is intended for ``dial on demand'' sites where DNS lookups +might cost real money. +Some simple error messages +(e.g., host unknown during the SMTP protocol) +will be delayed using this mode. +Mode +.q b +is the usual default. +.pp +If you run in mode +.q q +(queue only), +.q d +(defer), +or +.q b +(deliver in background) +.i sendmail +will not expand aliases and follow .forward files +upon initial receipt of the mail. +This speeds up the response to RCPT commands. +Mode +.q i +cannot be used by the SMTP server. +.sh 2 "Log Level" +.pp +The level of logging can be set for +.i sendmail . +The default using a standard configuration table is level 9. +The levels are as follows: +.nr ii 0.5i +.ip 0 +No logging. +.ip 1 +Serious system failures and potential security problems. +.ip 2 +Lost communications (network problems) and protocol failures. +.ip 3 +Other serious failures. +.ip 4 +Minor failures. +.ip 5 +Message collection statistics. +.ip 6 +Creation of error messages, +VRFY and EXPN commands. +.ip 7 +Delivery failures (host or user unknown, etc.). +.ip 8 +Successful deliveries and alias database rebuilds. +.ip 9 +Messages being deferred +(due to a host being down, etc.). +.ip 10 +Database expansion (alias, forward, and userdb lookups). +.ip 20 +Logs attempts to run locked queue files. +These are not errors, +but can be useful to note if your queue appears to be clogged. +.ip 30 +Lost locks (only if using lockf instead of flock). +.lp +Additionally, +values above 64 are reserved for extremely verbose debugging output. +No normal site would ever set these. +.sh 2 "File Modes" +.pp +The modes used for files depend on what functionality you want +and the level of security you require. +.sh 3 "To suid or not to suid?" +.pp +.i Sendmail +can safely be made +setuid to root. +At the point where it is about to +.i exec \|(2) +a mailer, +it checks to see if the userid is zero; +if so, +it resets the userid and groupid to a default +(set by the +.b u +and +.b g +options). +(This can be overridden +by setting the +.b S +flag to the mailer +for mailers that are trusted +and must be called as root.) +However, +this will cause mail processing +to be accounted +(using +.i sa \|(8)) +to root +rather than to the user sending the mail. +.pp +If you don't make +.i sendmail +setuid to root, it will still run but you lose a lot of functionality +and a lot of privacy, since you'll have to make the queue directory +world readable. +You could also make +.i sendmail +setuid to some pseudo-user +(e.g., create a user called +.q sendmail +and make +.i sendmail +setuid to that) +which will fix the privacy problems +but not the functionality issues. +Also, this isn't a guarantee of security: +for example, +root occasionally sends mail, +and the daemon often runs as root. +.sh 3 "Should my alias database be writable?" +.pp +At Berkeley +we have the alias database +(/etc/aliases*) +mode 644. +While this is not as flexible as if the database +were more 666, it avoids potential security problems +with a globally writable database. +.pp +The database that +.i sendmail +actually used +is represented by the two files +.i aliases.dir +and +.i aliases.pag +(both in /etc) +(or +.i aliases.db +if you are running with the new Berkeley database primitives). +The mode on these files should match the mode +on /etc/aliases. +If +.i aliases +is writable +and the +DBM +files +(\c +.i aliases.dir +and +.i aliases.pag ) +are not, +users will be unable to reflect their desired changes +through to the actual database. +However, +if +.i aliases +is read-only +and the DBM files are writable, +a slightly sophisticated user +can arrange to steal mail anyway. +.pp +If your DBM files are not writable by the world +or you do not have auto-rebuild enabled +(with the +.b AutoRebuildAliases +option), +then you must be careful to reconstruct the alias database +each time you change the text version: +.(b +newaliases +.)b +If this step is ignored or forgotten +any intended changes will also be ignored or forgotten. +.sh 2 "Connection Caching" +.pp +When processing the queue, +.i sendmail +will try to keep the last few open connections open +to avoid startup and shutdown costs. +This only applies to IPC connections. +.pp +When trying to open a connection +the cache is first searched. +If an open connection is found, it is probed to see if it is still active +by sending a +.sm NOOP +command. +It is not an error if this fails; +instead, the connection is closed and reopened. +.pp +Two parameters control the connection cache. +The +.b ConnectionCacheSize +(\c +.b k ) +option defines the number of simultaneous open connections +that will be permitted. +If it is set to zero, +connections will be closed as quickly as possible. +The default is one. +This should be set as appropriate for your system size; +it will limit the amount of system resources that +.i sendmail +will use during queue runs. +Never set this higher than 4. +.pp +The +.b ConnectionCacheTimeout +(\c +.b K ) +option specifies the maximum time that any cached connection +will be permitted to idle. +When the idle time exceeds this value +the connection is closed. +This number should be small +(under ten minutes) +to prevent you from grabbing too many resources +from other hosts. +The default is five minutes. +.sh 2 "Name Server Access" +.pp +Control of host address lookups is set by the +.b hosts +service entry in your service switch file. +If you are on a system that has built-in service switch support +(e.g., Ultrix, Solaris, or DEC OSF/1) +then your system is probably configured properly already. +Otherwise, +.i sendmail +will consult the file +.b /etc/service.switch , +which should be created. +.i Sendmail +only uses two entries: +.b hosts +and +.b aliases . +.pp +However, some systems (such as SunOS) +will do DNS lookups +regardless of the setting of the service switch entry. +In particular, the system routine +.i gethostbyname (3) +is used to look up host names, +and many vendor versions try some combination of DNS, NIS, +and file lookup in /etc/hosts +without consulting a service switch. +.i Sendmail +makes no attempt to work around this problem, +and the DNS lookup will be done anyway. +If you do not have a nameserver configured at all, +such as at a UUCP-only site, +.i sendmail +will get a +.q "connection refused" +message when it tries to connect to the name server. +If the +.b hosts +switch entry has the service +.q dns +listed somewhere in the list, +.i sendmail +will interpret this to mean a temporary failure +and will queue the mail for later processing; +otherwise, it ignores the name server data. +.pp +The same technique is used to decide whether to do MX lookups. +If you want MX support, you +.i must +have +.q dns +listed as a service in the +.b hosts +switch entry. +.pp +The +.b ResolverOptions +(\c +.b I ) +option allows you to tweak name server options. +The command line takes a series of flags as documented in +.i resolver (3) +(with the leading +.q RES_ +deleted). +Each can be preceded by an optional `+' or `\(mi'. +For example, the line +.(b +O ResolverOptions=+AAONLY \(miDNSRCH +.)b +turns on the AAONLY (accept authoritative answers only) +and turns off the DNSRCH (search the domain path) options. +Most resolver libraries default DNSRCH, DEFNAMES, and RECURSE +flags on and all others off. +You can also include +.q HasWildcardMX +to specify that there is a wildcard MX record matching your domain; +this turns off MX matching when canonifying names, +which can lead to inappropriate canonifications. +.pp +Version level 1 configurations +turn DNSRCH and DEFNAMES off when doing delivery lookups, +but leave them on everywhere else. +Version 8 of +.i sendmail +ignores them when doing canonification lookups +(that is, when using $[ ... $]), +and always does the search. +If you don't want to do automatic name extension, +don't call $[ ... $]. +.pp +The search rules for $[ ... $] are somewhat different than usual. +If the name being looked up +has at least one dot, it always tries the unmodified name first. +If that fails, it tries the reduced search path, +and lastly tries the unmodified name +(but only for names without a dot, +since names with a dot have already been tried). +This allows names such as +``utc.CS'' +to match the site in Czechoslovakia +rather than the site in your local Computer Science department. +It also prefers A and CNAME records over MX records \*- +that is, if it finds an MX record it makes note of it, +but keeps looking. +This way, if you have a wildcard MX record matching your domain, +it will not assume that all names match. +.pp +To completely turn off all name server access +on systems without service switch support +(such as SunOS) +you will have to recompile with +\-DNAMED_BIND=0 +and remove \-lresolv from the list of libraries to be searched +when linking. +.sh 2 "Moving the Per-User Forward Files" +.pp +Some sites mount each user's home directory +from a local disk on their workstation, +so that local access is fast. +However, the result is that .forward file lookups are slow. +In some cases, +mail can even be delivered on machines inappropriately +because of a file server being down. +The performance can be especially bad if you run the automounter. +.pp +The +.b ForwardPath +(\c +.b J ) +option allows you to set a path of forward files. +For example, the config file line +.(b +O ForwardPath=/var/forward/$u:$z/.forward.$w +.)b +would first look for a file with the same name as the user's login +in /var/forward; +if that is not found (or is inaccessible) +the file +``.forward.\c +.i machinename '' +in the user's home directory is searched. +A truly perverse site could also search by sender +by using $r, $s, or $f. +.pp +If you create a directory such as /var/forward, +it should be mode 1777 +(that is, the sticky bit should be set). +Users should create the files mode 644. +.sh 2 "Free Space" +.pp +On systems that have one of the system calls in the +.i statfs (2) +family +(including +.i statvfs +and +.i ustat ), +you can specify a minimum number of free blocks on the queue filesystem +using the +.b MinFreeBlocks +(\c +.b b ) +option. +If there are fewer than the indicated number of blocks free +on the filesystem on which the queue is mounted +the SMTP server will reject mail +with the +452 error code. +This invites the SMTP client to try again later. +.pp +Beware of setting this option too high; +it can cause rejection of email +when that mail would be processed without difficulty. +.sh 2 "Maximum Message Size" +.pp +To avoid overflowing your system with a large message, +the +.b MaxMessageSize +option can be set to set an absolute limit +on the size of any one message. +This will be advertised in the ESMTP dialogue +and checked during message collection. +.sh 2 "Privacy Flags" +.pp +The +.b PrivacyOptions +(\c +.b p ) +option allows you to set certain +``privacy'' +flags. +Actually, many of them don't give you any extra privacy, +rather just insisting that client SMTP servers +use the HELO command +before using certain commands +or adding extra headers to indicate possible spoof attempts. +.pp +The option takes a series of flag names; +the final privacy is the inclusive or of those flags. +For example: +.(b +O PrivacyOptions=needmailhelo, noexpn +.)b +insists that the HELO or EHLO command be used before a MAIL command is accepted +and disables the EXPN command. +.pp +The flags are detailed in section +.\"XREF +5.1.6. +.sh 2 "Send to Me Too" +.pp +Normally, +.i sendmail +deletes the (envelope) sender from any list expansions. +For example, if +.q matt +sends to a list that contains +.q matt +as one of the members he won't get a copy of the message. +If the +.b \-m +(me too) +command line flag, or if the +.b MeToo +(\c +.b m ) +option is set in the configuration file, +this behaviour is suppressed. +Some sites like to run the +.sm SMTP +daemon with +.b \-m . +.sh 1 "THE WHOLE SCOOP ON THE CONFIGURATION FILE" +.pp +This section describes the configuration file +in detail. +.pp +There is one point that should be made clear immediately: +the syntax of the configuration file +is designed to be reasonably easy to parse, +since this is done every time +.i sendmail +starts up, +rather than easy for a human to read or write. +On the +.q "future project" +list is a +configuration-file compiler. +.pp +The configuration file is organized as a series of lines, +each of which begins with a single character +defining the semantics for the rest of the line. +Lines beginning with a space or a tab +are continuation lines +(although the semantics are not well defined in many places). +Blank lines and lines beginning with a sharp symbol +(`#') +are comments. +.sh 2 "R and S \*- Rewriting Rules" +.pp +The core of address parsing +are the rewriting rules. +These are an ordered production system. +.i Sendmail +scans through the set of rewriting rules +looking for a match on the left hand side +(LHS) +of the rule. +When a rule matches, +the address is replaced by the right hand side +(RHS) +of the rule. +.pp +There are several sets of rewriting rules. +Some of the rewriting sets are used internally +and must have specific semantics. +Other rewriting sets +do not have specifically assigned semantics, +and may be referenced by the mailer definitions +or by other rewriting sets. +.pp +The syntax of these two commands are: +.(b F +.b S \c +.i n +.)b +Sets the current ruleset being collected to +.i n . +If you begin a ruleset more than once +it deletes the old definition. +.(b F +.b R \c +.i lhs +.i rhs +.i comments +.)b +The +fields must be separated +by at least one tab character; +there may be embedded spaces +in the fields. +The +.i lhs +is a pattern that is applied to the input. +If it matches, +the input is rewritten to the +.i rhs . +The +.i comments +are ignored. +.pp +Macro expansions of the form +.b $ \c +.i x +are performed when the configuration file is read. +Expansions of the form +.b $& \c +.i x +are performed at run time using a somewhat less general algorithm. +This for is intended only for referencing internally defined macros +such as +.b $h +that are changed at runtime. +.sh 3 "The left hand side" +.pp +The left hand side of rewriting rules contains a pattern. +Normal words are simply matched directly. +Metasyntax is introduced using a

database(s) +and replaced by the canonical name\**. +.(f +\**This is actually +completely equivalent +to $(host \fIhostname\fP$). +In particular, a +.b $: +default can be used. +.)f +For example, +.q $[ftp$] +might become +.q ftp.CS.Berkeley.EDU +and +.q $[[128.32.130.2]$] +would become +.q vangogh.CS.Berkeley.EDU. +.i Sendmail +recognizes it's numeric IP address +without calling the name server +and replaces it with it's canonical name. +.pp +The +.b $( +\&... +.b $) +syntax is a more general form of lookup; +it uses a named map instead of an implicit map. +If no lookup is found, the indicated +.i default +is inserted; +if no default is specified and no lookup matches, +the value is left unchanged. +The +.i arguments +are passed to the map for possible use. +.pp +The +.b $> \c +.i n +syntax +causes the remainder of the line to be substituted as usual +and then passed as the argument to ruleset +.i n . +The final value of ruleset +.i n +then becomes +the substitution for this rule. +The +.b $> +syntax can only be used at the beginning of the right hand side; +it can be only be preceded by +.b $@ +or +.b $: . +.pp +The +.b $# +syntax should +.i only +be used in ruleset zero +or a subroutine of ruleset zero. +It causes evaluation of the ruleset to terminate immediately, +and signals to +.i sendmail +that the address has completely resolved. +The complete syntax is: +.(b

a colon-separated list of hosts +that are searched in order for the first working address +(exactly like MX records). +The +.i user +is later rewritten by the mailer-specific envelope rewriting set +and assigned to the +.b $u +macro. +As a special case, if the value to +.b $# +is +.q local +and the first character of the +.b $: +value is +.q @ , +the +.q @ +is stripped off, and a flag is set in the address descriptor +that causes sendmail to not do ruleset 5 processing. +.pp +Normally, a rule that matches is retried, +that is, +the rule loops until it fails. +A RHS may also be preceded by a +.b $@ +or a +.b $: +to change this behavior. +A +.b $@ +prefix causes the ruleset to return with the remainder of the RHS +as the value. +A +.b $: +prefix causes the rule to terminate immediately, +but the ruleset to continue; +this can be used to avoid continued application of a rule. +The prefix is stripped before continuing. +.pp +The +.b $@ +and +.b $: +prefixes may precede a +.b $> +spec; +for example: +.(b +.ta 8n +R$+ $: $>7 $1 +.)b +matches anything, +passes that to ruleset seven, +and continues; +the +.b $: +is necessary to avoid an infinite loop. +.pp +Substitution occurs in the

(essentially) one long MX list. +The intent here is to create +.q fake +MX records that are not published in DNS +for private internal networks. +.pp +As a final special case, the host name can be

firewall +or other host that will do special processing for all your mail, +so that your MX record points to a gateway machine; +this machine could then do direct delivery to machines +within your local domain. +Use of this feature directly violates RFC 1123 section 5.3.5: +it should not be used lightly. +.r +.sh 2 "D \*- Define Macro" +.pp +Macros are named with a single character +or with a word in {braces}. +Single character names may be selected from the entire ASCII set, +but user-defined macros +should be selected from the set of upper case letters only. +Lower case letters +and special symbols +are used internally. +Long names beginning with a lower case letter or a punctuation character +are reserved for use by sendmail, +so user-defined long macro names should begin with an upper case letter. +.pp +The syntax for macro definitions is: +.(b F +.b D \c +.i x\|val +.)b +where +.i x +is the name of the macro +(which may be a single character +or a word in braces) +and +.i val +is the value it should have. +There should be no spaces given +that do not actually belong in the macro value. +.pp +Macros are interpolated +using the construct +.b $ \c +.i x , +where +.i x +is

can be used. +The +.b $a +and +.b $b +macros are in RFC 822 format; +.b $a +is the time as extracted from the +.q Date: +line of the message +(if there was one), +and +.b $b +is the current date and time +(used for postmarks). +If no +.q Date: +line is found in the incoming message, +.b $a +is set to the current time also. +The +.b $d +macro is equivalent to the +.b $b +macro in UNIX +(ctime) +format. +.pp +The macros +.b $w , +.b $j , +and +.b $m +are set to the identity of this host. +.i Sendmail +tries to find the fully qualified name of the host +if at all possible; +it does this by calling +.i gethostname (2) +to get the current hostname +and then passing that to +.i gethostbyname (3) +which is supposed to return the canonical version of that host name.\** +.(f +\**For example, on some systems +.i gethostname +might return +.q foo +which would be mapped to +.q foo.bar.com +by +.i gethostbyname . +.)f +Assuming this is successful, +.b $j +is set to the fully qualified name +and +.b $m +is set to the domain part of the name +(everything after the first dot). +The +.b $w +macro is set to the first word +(everything before the first dot) +if you have a level 5 or higher configuration file; +otherwise, it is set to the same value as +.b $j . +If the canonification is not successful, +it is imperative that the config file set +.b $j +to the fully qualified domain name\**. +.(f +\**Older versions of sendmail didn't pre-define +.b $j +at all, so up until 8.6, +config files +.i always +had to define +.b $j . +.)f +.pp +The +.b $f +macro is the id of the sender +as originally determined; +when mailing to a specific host +the +.b $g +macro is set to the address of the sender +.ul +relative to the recipient. +For example, +if I send to +.q bollard@matisse.CS.Berkeley.EDU +from the machine +.q vangogh.CS.Berkeley.EDU +the +.b $f +macro will be +.q eric +and the +.b $g +macro will be +.q eric@vangogh.CS.Berkeley.EDU. +.pp +The +.b $x +macro is set to the full name of the sender. +This can be determined in several ways. +It can be passed as flag to +.i sendmail . +It can be defined in the +.sm NAME +environment variable. +The third choice is the value of the +.q Full-Name: +line in the header if it exists, +and the fourth choice is the comment field +of a +.q From: +line. +If all of these fail, +and if the message is being originated locally, +the full name is looked up in the +.i /etc/passwd +file. +.pp +When sending, +the +.b $h , +.b $u , +and +.b $z +macros get set to the host, user, and home directory +(if local) +of the recipient. +The first two are set from the +.b $@ +and +.b $: +part of the rewriting rules, respectively. +.pp +The +.b $p +and +.b $t +macros are used to create unique strings +(e.g., for the +.q Message-Id: +field). +The +.b $i +macro is set to the queue id on this host; +if put into the timestamp line +it can be extremely useful for tracking messages. +The +.b $v +macro is set to be the version number of +.i sendmail ; +this is normally put in timestamps +and has been proven extremely useful for debugging. +.pp +The +.b $c +field is set to the +.q "hop count," +i.e., the number of times this message has been processed. +This can be determined +by the +.b \-h +flag on the command line +or by counting the timestamps in the message. +.pp +The +.b $r +and +.b $s +fields are set to the protocol used to communicate with +.i sendmail +and the sending hostname. +They can be set together using the +.b \-p +command line flag or separately using the +.b \-M +or +.b \-oM +flags. +.pp +The +.b $_ +is set to a validated sender host name. +If the sender is running an RFC 1413 compliant IDENT server +and the receiver has the IDENT protocol turned on, +it will include the user name on that host. +.sh 2 "C and F \*- Define Classes" +.pp +Classes of phrases may be defined +to match on the left hand side of rewriting rules, +where a +.q phrase +is a sequence of characters that do not contain space characters. +For example +a class of all local names for this site +might be created +so that attempts to send to oneself +can be eliminated. +These can either be defined directly in the configuration file +or read in from another file. +Classes are named as a single letter or a word in {braces}. +Class names beginning with lower case letters +and special characters are reserved for system use. +Classes defined in config files may be given names +from the set of upper case letters for short names +or beginning with an upper case letter for long names. +.pp +The syntax is: +.(b F +.b C \c +.i c\|phrase1 +.i phrase2... +.br +.b F \c +.i c\|file +.)b +The first form defines the class +.i c +to match any of the named words. +It is permissible to split them among multiple lines; +for example, the two forms: +.(b +CHmonet ucbmonet +.)b +and +.(b +CHmonet +CHucbmonet +.)b +are equivalent. +The ``F'' form +reads the elements of the class +.i c +from the named +.i file . +.pp +Elements of classes can be accessed in rules using +.b $= +or +.b $~ . +The +.b $~ +(match entries not in class) +only matches a single word; +multi-word entries in the class are ignored in this context. +.pp +The class +.b $=w +is set to be the set of all names +this host is known by. +This can be used to match local hostnames. +.pp +The class +.b $=k +is set to be the same as +.b $k , +that is, the UUCP node name. +.pp +The class +.b $=m +is set to the set of domains by which this host is known, +initially just +.b $m . +.pp +The class +.b $=t +is set to the set of trusted users by the +.b T +configuration line. +If you want to read trusted users from a file use +.b Ft \c +.i /file/name . +.pp +The class +.b $=n +can be set to the set of MIME body types +that can never be eight to seven bit encoded. +It defaults to +.q multipart/signed . +Message types +.q message/* +and +.q multipart/* +are never encoded directly. +Multipart messages are always handled recursively. +The handling of message/* messages +are controlled by class +.b $=s . +The class +.b $=e +contains the Content-Transfer-Encodings that can be 8\(->7 bit encoded. +It is predefined to contain +.q 7bit , +.q 8bit , +and +.q binary . +The class +.b $=s +contains the set of subtypes of message that can be treated recursively. +By default it contains only +.q rfc822 . +Other +.q message/* +types cannot be 8\(->7 bit encoded. +If a message containing eight bit data is sent to a seven bit host, +and that message cannot be encoded into seven bits, +it will be stripped to 7 bits. +.pp +.i Sendmail +can be compiled to allow a +.i scanf (3) +string on the +.b F +line. +This lets you do simplistic parsing of text files. +For example, to read all the user names in your system +.i /etc/passwd +file into a class, use +.(b +FL/etc/passwd %[^:] +.)b +which reads every line up to the first colon. +.sh 2 "M \*- Define Mailer" +.pp +Programs and interfaces to mailers +are defined in this line. +The format

The MTS type information (used for error messages) +.)b +Only the first character of the field name is checked. +.pp +The following flags may be set in the mailer description. +Any other flags may be used freely +to conditionally assign headers to messages +destined for particular mailers. +Flags marked with \(dg +are not interpreted by the +.i sendmail +binary; +these are the conventionally used to correlate to the flags portion +of the +.b H +line. +Flags marked with \(dd +apply to the mailers for the sender address +rather than the usual recipient mailers. +.nr ii 4n +.ip a +Run Extended

alias database. +Normally this is only set for local mailers. +.ip b +Force a blank line on the end of a message. +This is intended to work around some stupid versions of +/bin/mail +that require a blank line, but do not provide it themselves. +It would not normally be used on network mail. +.ip c +Do not include comments in addresses. +This should only be used if you have to work around +a remote mailer that gets confused by comments. +This strips addresses of the form +.q "Phrase <address>" +or +.q "address (Comment)" +down to just +.q address . +.ip C\(dd +If mail is +.i received +from a mailer with this flag set, +any addresses in the header that do not have an at sign +(\c +.q @ ) +after being rewritten by ruleset three +will have the +.q @domain +clause from the sender envelope address +tacked on. +This allows mail with headers of the form: +.(b +From: usera@hosta +To: userb@hostb, userc +.)b +to be rewritten as: +.(b +From: usera@hosta +To: userb@hostb, userc@hosta

only if this is a network forward operation +(i.e., +the mailer will give an error +if the executing user +does not have special permissions). +.ip F\(dg +This mailer wants a +.q From: +header line. +.ip g +Normally, +.i sendmail +sends internally generated email (e.g., error messages) +using the null return address +as required by RFC 1123. +However, some mailers don't accept a null return address. +If necessary, +you can set the +.b g +flag to prevent +.i sendmail +from obeying the standards; +error messages will be sent as from the MAILER-DAEMON +(actually, the value of the +.b $n

+This option is not required +(i.e., +if this option is omitted the transmission will still operate successfully, +although perhaps not as efficiently as possible). +.ip k +Normally when +.i sendmail +connects to a host via SMTP, +it checks to make sure that this isn't accidently the same host name +as might happen if +.i sendmail +is misconfigured or if a long-haul network interface is set in loopback mode. +This flag disables the loopback check. +It should only be used under very unusual circumstances. +.ip K +Currently unimplemented. +Reserved for chunking. +.ip l +This mailer is local +(i.e., +final delivery will be performed). +.ip L +Limit the line lengths as specified in RFC821. +This deprecated option should be replaced by the +.b L= +mail declaration. +For historic reasons, the +.b L +flag also sets the +.b 7 +flag. +.ip m +This mailer can send to multiple users +on the same host +in one transaction. +When a +.b $u +macro occurs in the +.i argv +part of the mailer definition, +that field will be repeated as necessary +for all qualifying users. +.ip M\(dg +This mailer wants a +.q Message-Id: +header line. +.ip n +Do not insert a UNIX-style +.q From +line on the front of the message. +.ip o +Always run as the owner of the recipient mailbox. +Normally +.i sendmail +runs as the sender for locally generated mail +or as +.q daemon +(actually, the user specified in the +.b u +option) +when delivering network mail. +The normal behaviour is required by most local mailers, +which will not allow the envelope sender address +to be set unless the mailer is running as daemon. +This flag is ignored if the +.b S +flag is set. +.ip p +Use the route-addr style reverse-path in the SMTP +.q "MAIL FROM:" +command +rather than just the return address; +although this is required in RFC821 section 3.1, +many hosts do not process reverse-paths properly. +Reverse-paths are officially discouraged by RFC 1123. +.ip P\(dg +This mailer wants a +.q Return-Path: +line. +.ip r +Same as +.b f , +but sends a +.b \-r +flag. +.ip s +Strip quote characters (" and \e) off of the address +before calling the mailer. +.ip S +Don't reset the userid +before calling the mailer. +This

be set to that user and group +(instead of leaving it as root). +.ip u +Upper case should be preserved in user names +for this mailer. +.ip U +This mailer wants UUCP-style +.q From +lines with the ugly +.q "remote from <host>" +on the end. +.ip w +The user must have a valid account on this machine, +i.e., +getpwnam +must succeed. +If not, +the mail is bounced. +This is required to get +.q \&.forward +capability. +.ip x\(dg +This mailer wants a +.q Full-Name: +header line. +.ip X +This mailer want to use the hidden dot algorithm +as specified in RFC821; +basically, +any line beginning with a dot +will have an extra dot prepended +(to be stripped at the other end). +This insures that lines in the message containing a dot +will not terminate the message prematurely. +.ip 5 +If no aliases are found for this address, +pass the address through ruleset 5 for possible alternate resolution. +This is intended to forward the mail to an alternate delivery spot. +.ip 7 +Strip all output to seven bits. +This is the default if the +.b L +flag is set. +Note that clearing this option is not +sufficient to get full eight bit data passed through +.i sendmail . +If the +.b 7 +option is set, this is essentially always set, +since the eighth bit was stripped on input. +Note that this option will only impact messages +that didn't have 8\(->7 bit MIME conversions performed. +.ip 8 +If set, +it is acceptable to send eight bit data to this mailer; +the usual attempt to do 8\(->7 bit MIME conversions will be bypassed. +.ip : +Check addresses to see if they begin +.q :include: ; +if they do, convert them to the +.q *include* +mailer. +.ip | +Check addresses to see if they begin with a `|'; +if they do, convert them to the +.q prog +mailer. +.ip / +Check addresses to see if they begin with a `/'; +if they do, convert them to the +.q *file* +mailer. +.ip @ +Look up addresses in the user database. +.pp +Configuration files prior to level 6 +assume the `A', `w', `5', `:', `|', `/', and `@' options +on the mailer named +.q local . +.pp +The mailer with the special name +.q error +can be used to generate a user error. +The (optional) host field is an exit status to be returned, +and the user field is a message to be printed. +The exit status may be numeric or one of the values +USAGE, NOUSER, NOHOST, UNAVAILABLE, SOFTWARE, TEMPFAIL, PROTOCOL, or CONFIG +to return the corresponding EX_ exit code. +For example, the entry: +.(b +$#error $@ NOHOST $: Host unknown in this domain +.)b +on the RHS of a rule +will cause the specified error to be generated +and the +.q "Host unknown" +exit status to be returned +if the LHS matches. +This mailer is only functional in rulesets zero or five. +.pp +The mailer named +.q local +.i must +be defined in every configuration file. +This is used to deliver local mail, +and is treated specially in several ways. +Additionally, three other mailers named +.q prog , +.q *file* , +and +.q *include* +may be defined to tune the delivery of messages to programs, +files, +and :include: lists respectively. +They default to: +.(b +Mprog, P=/bin/sh, F=lsD, A=sh \-c $u +M*file*, P=/dev/null, F=lsDFMPEu, A=FILE +M*include*, P=/dev/null, F=su, A=INCLUDE +.)b +.pp +The Sender and Recipient rewriting sets +may either be a simple ruleset id +or may be two ids separated by a slash; +if so, the first rewriting set is applied to envelope +addresses +and the second is applied to headers. +.pp +The Directory +is actually a colon-separated path of directories to try. +For example, the definition +.q D=$z:/ +first tries to execute in the recipient's home directory; +if that is not available, +it tries to execute in the root of the filesystem. +This is intended to be used only on the +.q prog +mailer, +since some shells (such as +.i csh ) +refuse to execute if they cannot read the home directory. +Since the queue directory is not normally readable by unprivileged users +.i csh +scripts as recipients can fail. +.pp +The Userid +specifies the default user and group id to run as, +overriding the +.b DefaultUser +option (q.v.). +If the +.b S +mailer flag is also specified, +this is the user and group to run as in all circumstances. +This may be given as +.i user:group +to set both the user and group id; +either may be an integer or a symbolic name to be looked up +in the +.i passwd +and +.i group +files respectively. +If only a symbolic user name is specified, +the group id in the +.i passwd +file for that user is used as the group id. +.pp +The Charset field +is used when converting a message to MIME; +this is the character set used in the +Content-Type: header. +If this is not set, the +.b DefaultCharset +option is used, +and if that is not set, the value +.q unknown-8bit +is used. +.b WARNING: +this field applies to the sender's mailer, +not the recipient's mailer. +For example, if the envelope sender address +lists an address on the local network +and the recipient is on an external network, +the character set will be set from the Charset= field +for the local network mailer, +not that of the external network mailer. +.pp +The Type= field +sets the type information +used in MIME error messages +as defined by +RFC XXX +(not yet published). +It is actually three values separated by slashes: +the MTA-type (that is, the description of how hosts are named), +the address type (the description of e-mail addresses), +and the diagnostic type (the description of error diagnostic codes). +Each of these must be a registered value +or begin with +.q X\- . +The default is +.q dns/rfc822/smtp . +.sh 2 "H \*- Define Header" +.pp +The format of the header lines that +.i sendmail +inserts into the message +are defined by the +.b H +line. +The syntax of this line is: +.(b F +.b H [\c +.b ? \c +.i mflags \c +.b ? ]\c +.i hname \c +.b : +.i htemplate +.)b +Continuation lines in this spec +are reflected directly into the outgoing message. +The +.i htemplate +is macro expanded before insertion into the message. +If the +.i mflags +(surrounded by question marks) +are specified, +at least one of the specified flags +must be stated in the mailer definition +for this header to be automatically output. +If one of these headers is in the input +it is reflected to the output +regardless of these flags. +.pp +Some headers have special semantics +that will be described later. +.sh 2 "O \*- Set Option" +.pp +There are a number of +global +options that +can be set from a configuration file. +Options are represented by full words; +some are also representable as single characters +for back compatibility. +The syntax of this line is: +.(b F +.b O \0 +.i option \c +.b = \c +.i value +.)b +This sets option +.i option +to be +.i value . +Note that there +.i must +be a space between the letter `O' and the name of the option. +An older version is: +.(b F +.b O \c +.i o\|value +.)b +where the option +.i o +is a single character. +Depending on the option, +.i value +may be a string, an integer, +a boolean +(with legal values +.q t , +.q T , +.q f , +or +.q F ; +the default is TRUE), +or +a time interval. +.pp +The options supported (with the old, one character names in brackets) are: +.nr ii 1i +.ip "AliasFile=\fIspec, spec, ...\fP" +[A] +Specify possible alias file(s). +Each +.i spec +should be in the format +``\c +.i class \c +.b : +.i file '' +where +.i class \c +.b : +is optional and defaults to ``implicit''. +Depending on how +.i sendmail +is compiled, valid classes are +.q implicit +(search through a compiled-in list of alias file types, +for back compatibility), +.q hash +(if +.sm NEWDB +is specified), +.q dbm +(if +.sm NDBM +is specified), +.q stab +(internal symbol table \*- not normally used +unless you have no other database lookup), +or +.q nis +(if +.sm NIS +is specified). +If a list of +.i spec s +are provided, +.i sendmail +searches them in order. +.ip AliasWait=\fItimeout\fP +[a] +If set, +wait up to +.i timeout +(units default to minutes) +for an +.q @:@ +entry to exist in the alias database +before starting up. +If it does not appear in the +.i timeout +interval +rebuild the database +(if the +.b AutoRebuildAliases +option is also set) +or issue a warning. +.ip AutoRebuildAliases +[D] +If set, +rebuild the alias database if necessary and possible. +If this option is not set, +.i sendmail +will never rebuild the alias database +unless explicitly requested +using +.b \-bi . +Not recommended \(em can cause thrashing. +.ip BlankSub=\fIc\fP +[B] +Set the blank substitution character to +.i c . +Unquoted spaces in addresses are replaced by this character. +Defaults to space (i.e., no change is made). +.ip CheckAliases +[n] +Validate the RHS of aliases when rebuilding the alias database. +.ip CheckpointInterval=\fIN\fP +[C] +Checkpoints the queue every +.i N +(default 10) +addresses sent. +If your system crashes during delivery to a large list, +this prevents retransmission to any but the last +.I N +recipients. +.ip ClassFactor=\fIfact\fP +[z] +The indicated +.i fact or +is multiplied by the message class +(determined by the Precedence: field in the user header +and the +.b P +lines in the configuration file) +and subtracted from the priority. +Thus, messages with a higher Priority: will be favored. +Defaults to 1800. +.ip ColonOkInAddr +[no short name] +If set, colons are acceptable in e-mail addresses +(e.g., +.q host:user ). +If not set, colons indicate the beginning of a RFC 822 group construct +(\c +.q "groupname: member1, member2, ... memberN;" ). +Doubled colons are always acceptable +(\c +.q nodename::user ) +and proper route-addr nesting is understood +(\c +.q <@relay:user@host> ). +Furthermore, this option defaults on if the configuration version level +is less than 6 (for back compatibility). +However, it must be off for full compatibility with RFC 822. +.ip ConnectionCacheSize=\fIN\fP +[k] +The maximum number of open connections that will be cached at a time. +The default is one. +This delays closing the current connection until +either this invocation of +.i sendmail +needs to connect to another host +or it terminates. +Setting it to zero defaults to the old behavior, +that is, connections are closed immediately. +Since this consumes file descriptors, +the connection cache should be kept small: +4 is probably a practical maximum. +.ip ConnectionCacheTimeout=\fItimeout\fP +[K] +The maximum amount of time a cached connection will be permitted to idle +without activity. +If this time is exceeded, +the connection is immediately closed. +This value should be small (on the order of ten minutes). +Before +.i sendmail +uses a cached connection, +it always sends a RSET command +to check the connection; +if this fails, it reopens the connection. +This keeps your end from failing if the other end times out. +The point of this option is to be a good network neighbor +and avoid using up excessive resources +on the other end. +The default is five minutes. +.ip DaemonPortOptions=\fIoptions\fP +[O] +Set server SMTP options. +The options are +.i key=value +pairs. +Known keys are: +.(b +.ta 1i +Port Name/number of listening port (defaults to "smtp") +Addr Address mask (defaults INADDR_ANY) +Family Address family (defaults to INET) +Listen Size of listen queue (defaults to 10) +SndBufSize Size of TCP send buffer +RcvBufSize Size of TCP receive buffer +.)b +The +.i Addr ess +mask may be a numeric address in dot notation +or a network name. +.ip DefaultCharSet=\fIcharset\fP +[no short name] +When a message that has 8-bit characters but is not in MIME format +is converted to MIME +(see the EightBitMode option) +a character set must be included in the Content-Type: header. +This character set is normally set from the Charset= field +of the mailer descriptor. +If that is not set, the value of this option is used. +If this option is not set, the value +.q unknown-8bit +is used. +.ip DefaultUser=\fIuser:group\fP +[u] +Set the default userid for mailers to +.i user:group . +If +.i group +is omitted and +.i user +is a user name +(as opposed to a numeric user id) +the default group listed in the /etc/passwd file for that user is used +as the default group. +Both +.i user +and +.i group +may be numeric. +Mailers without the +.i S +flag in the mailer definition +will run as this user. +Defaults to 1:1. +The value can also be given as a symbolic user name.\** +.(f +\**The old +.b g +option has been combined into the +.b DefaultUser +option. +.)f +.ip DeliveryMode=\fIx\fP +[d] +Deliver in mode +.i x . +Legal modes are: +.(b +.ta 4n +i Deliver interactively (synchronously) +b Deliver in background (asynchronously) +q Just queue the message (deliver during queue run) +d Defer delivery and all map lookups (deliver during queue run) +.)b +Defaults to ``b'' if no option is specified, +``i'' if it is specified but given no argument +(i.e., ``Od'' is equivalent to ``Odi''). +The +.b \-v +command line flag sets this to +.b i . +.ip DialDelay=\fIsleeptime\fP +[no short name] +Dial-on-demand network connections can see timeouts +if a connection is opened before the call is set up. +If this is set to an interval and a connection times out +on the first connection being attempted +.i sendmail +will sleep for this amount of time and try again. +This should give your system time to establish the connection +to your service provider. +Units default to seconds, so +.q DialDelay=5 +uses a five second delay. +Defaults to zero +(no retry). +.ip DontExpandCnames +[no short name] +The standards say that all host addresses used in a mail message +must be fully canonical. +For example, if your host is named +.q Cruft.Foo.ORG +and also has an alias of +.q FTP.Foo.ORG , +the former name must be used at all times. +This is enforced during host name canonification +($[ ... $] lookups). +If this option is set, the protocols are ignored and the +.q wrong +thing is done. +However, the IETF is moving toward changing this standard, +so the behaviour may become acceptable. +Please note that hosts downstream may still rewrite the address +to be the true canonical name however. +.ip DontInitGroups +[no short name] +If set, +.i sendmail +will avoid using the initgroups(3) call. +If you are running NIS, +this causes a sequential scan of the groups.byname map, +which can cause your NIS server to be badly overloaded in a large domain. +The cost of this is that the only group found for users +will be their primary group (the one in the password file), +which will make file access permissions somewhat more restrictive. +Has no effect on systems that don't have group lists. +.ip DontPruneRoutes +[R] +Normally, +.i sendmail +tries to eliminate any unnecessary explicit routes +when sending an error message +(as discussed in RFC 1123 \(sc 5.2.6). +For example, +when sending an error message to +.(b +<@known1,@known2,@known3:user@unknown> +.)b +.i sendmail +will strip off the +.q @known1,@known2 +in order to make the route as direct as possible. +However, if the +.b R +option is set, this will be disabled, +and the mail will be sent to the first address in the route, +even if later addresses are known. +This may be useful if you are caught behind a firewall. +.ip EightBitMode=\fIaction\fP +[8] +Set handling of eight-bit data. +There are two kinds of eight-bit data: +that declared as such using the +.b BODY=8BITMIME +ESMTP declaration or the +.b \-B8BITMIME +command line flag, +and undeclared 8-bit data, that is, +input that just happens to be eight bits. +There are three basic operations that can happen: +undeclared 8-bit data can be automatically converted to 8BITMIME, +undeclared 8-bit data can be passed as-is without conversion to MIME +(``just send 8''), +and declared 8-bit data can be converted to 7-bits +for transmission to a non-8BITMIME mailer. +The possible +.i action s +are: +.(b +.\" r Reject undeclared 8-bit data; +.\" don't convert 8BITMIME\(->7BIT (``reject'') + s Reject undeclared 8-bit data (``strict'') +.\" do convert 8BITMIME\(->7BIT (``strict'') +.\" c Convert undeclared 8-bit data to MIME; +.\" don't convert 8BITMIME\(->7BIT (``convert'') + m Convert undeclared 8-bit data to MIME (``mime'') +.\" do convert 8BITMIME\(->7BIT (``mime'') +.\" j Pass undeclared 8-bit data; +.\" don't convert 8BITMIME\(->7BIT (``just send 8'') + p Pass undeclared 8-bit data (``pass'') +.\" do convert 8BITMIME\(->7BIT (``pass'') +.\" a Adaptive algorithm: see below +.)b +.\"The adaptive algorithm is to accept 8-bit data, +.\"converting it to 8BITMIME only if the receiver understands that, +.\"otherwise just passing it as undeclared 8-bit data; +.\"8BITMIME\(->7BIT conversions are done. +In all cases properly declared 8BITMIME data will be converted to 7BIT +as needed. +.ip ErrorHeader=\fIfile-or-message\fP +[E] +Prepend error messages with the indicated message. +If it begins with a slash, +it is assumed to be the pathname of a file +containing a message (this is the recommended setting). +Otherwise, it is a literal message. +The error file might contain the name, email address, and/or phone number +of a local postmaster who could provide assistance +in to end users. +If the option is missing or null, +or if it names a file which does not exist or which is not readable, +no message is printed. +.ip ErrorMode=\fIx\fP +[e] +Dispose of errors using mode +.i x . +The values for +.i x +are: +.(b +p Print error messages (default) +q No messages, just give exit status +m Mail back errors +w Write back errors (mail if user not logged in) +e Mail back errors and give zero exit stat always +.)b +.ip FallbackMXhost=\fIfallbackhost\fP +[V] +If specified, the +.i fallbackhost +acts like a very low priority MX +on every host. +This is intended to be used by sites with poor network connectivity. +.ip ForkEachJob +[Y] +If set, +deliver each job that is run from the queue in a separate process. +Use this option if you are short of memory, +since the default tends to consume considerable amounts of memory +while the queue is being processed. +.ip ForwardPath=\fIpath\fP +[J] +Set the path for searching for users' .forward files. +The default is +.q $z/.forward . +Some sites that use the automounter may prefer to change this to +.q /var/forward/$u +to search a file with the same name as the user in a system directory. +It can also be set to a sequence of paths separated by colons; +.i sendmail +stops at the first file it can successfully and safely open. +For example, +.q /var/forward/$u:$z/.forward +will search first in /var/forward/\c +.i username +and then in +.i ~username /.forward +(but only if the first file does not exist). +.ip HelpFile=\fIfile\fP +[H] +Specify the help file +for SMTP. +.ip HoldExpensive +[c] +If an outgoing mailer is marked as being expensive, +don't connect immediately. +This requires that queueing be compiled in, +since it will depend on a queue run process to +actually send the mail. +.ip IgnoreDots +[i] +Ignore dots in incoming messages. +This is always disabled (that is, dots are always accepted) +when reading SMTP mail. +.ip LogLevel=\fIn\fP +[L] +Set the default log level to +.i n . +Defaults to 9. +.ip M\fIx\|value\fP +[no long version] +Set the macro +.i x +to +.i value . +This is intended only for use from the command line. +The +.b \-M +flag is preferred. +.ip MatchGECOS +[G] +Allow fuzzy matching on the GECOS field. +If this flag is set, +and the usual user name lookups fail +(that is, there is no alias with this name and a +.i getpwnam +fails), +sequentially search the password file +for a matching entry in the GECOS field. +This also requires that MATCHGECOS +be turned on during compilation. +This option is not recommended. +.ip MaxHopCount=\fIN\fP +[h] +The maximum hop count. +Messages that have been processed more than +.i N +times are assumed to be in a loop and are rejected. +Defaults to 25. +.ip MaxHostStatAge=\fIage\fP +[no short name] +Not yet implemented. +This option specifies how long host status information will be retained. +For example, if a host is found to be down, +connections to that host will not be retried for this interval. +The units default to minutes. +.ip MaxQueueRunSize=\fIN\fP +[no short name] +The maximum number of jobs that will be processed +in a single queue run. +If not set, there is no limit on the size. +If you have very large queues or a very short queue run interval +this could be unstable. +However, since the first +.i N +jobs in queue directory order are run (rather than the +.i N +highest priority jobs) +this should be set as high as possible to avoid +.q losing +jobs that happen to fall late in the queue directory. +.ip MeToo +[m] +Send to me too, +even if I am in an alias expansion. +.ip MaxMessageSize=\fIN\fP +[no short name] +Specify the maximum message size +to be advertised in the ESMTP EHLO response. +Messages larger than this will be rejected. +.ip MinFreeBlocks=\fIN\fP +[b] +Insist on at least +.i N +blocks free on the filesystem that holds the queue files +before accepting email via SMTP. +If there is insufficient space +.i sendmail +gives a 452 response +to the MAIL command. +This invites the sender to try again later. +.ip MinQueueAge=\fPage\fP +[no short name] +Don't process any queued jobs +that have been in the queue less than the indicated time interval. +This is intended to allow you to get responsiveness +by processing the queue fairly frequently +without thrashing your system by trying jobs too often. +The default units are minutes. +.ip NoRecipientAction +[no short name] +The action to take when you receive a message that has no valid +recipient headers (To:, Cc:, Bcc:). +It can be +.b None +to pass the message on unmodified, +which violates the protocol, +.b Add-To +to add a To: header with any recipients it can find in the envelope +(which might expose Bcc: recipients), +.b Add-Apparently-To +to add an Apparently-To: header +(this is only for back-compatibility +and is officially deprecated), +.b Add-To-Undisclosed +to add a header +.q "To: undisclosed-recipients:;" +to make the header legal without disclosing anything, +or +.b Add-Bcc +to add an empty Bcc: header. +.ip OldStyleHeaders +[o] +Assume that the headers may be in old format, +i.e., +spaces delimit names. +This actually turns on +an adaptive algorithm: +if any recipient address contains a comma, parenthesis, +or angle bracket, +it will be assumed that commas already exist. +If this flag is not on, +only commas delimit names. +Headers are always output with commas between the names. +Defaults to off. +.ip OperatorChars=\fIcharlist\fP +[$o macro] +The list of characters that are considered to be +.q operators , +that is, characters that delimit tokens. +All operator characters are tokens by themselves; +sequences of non-operator characters are also tokens. +White space characters separate tokens +but are not tokens themselves \(em for example, +.q AAA.BBB +has three tokens, but +.q "AAA BBB" +has two. +If not set, OperatorChars defaults to +.q \&.\|:\|@\|[\|] ; +additionally, the characters +.q (\|)\|<\|>\|,\|; +are always operators. +.ip PostmasterCopy=\fIpostmaster\fP +[P] +If set, +copies of error messages will be sent to the named +.i postmaster . +Only the header of the failed message is sent. +Since most errors are user problems, +this is probably not a good idea on large sites, +and arguably contains all sorts of privacy violations, +but it seems to be popular with certain operating systems vendors. +Defaults to no postmaster copies. +.ip PrivacyOptions=\fI\|opt,opt,...\fP +[p] +Set the privacy +.i opt ions. +``Privacy'' is really a misnomer; +many of these are just a way of insisting on stricter adherence +to the SMTP protocol. +The +.i opt ions +can be selected from: +.(b +.ta \w'needvrfyhelo'u+3n +public Allow open access +needmailhelo Insist on HELO or

+restrictmailq Restrict mailq command +restrictqrun Restrict \-q command line flag +noreceipts Don't return success DSNs +goaway Disallow essentially all SMTP status queries +authwarnings Put X-Authentication-Warning: headers in messages +.)b +The +.q goaway +pseudo-flag sets all flags except +.q restrictmailq +and +.q restrictqrun . +If mailq is restricted, +only people in the same group as the queue directory +can print the queue. +If queue runs are restricted, +only root and the owner of the queue directory +can run the queue. +Authentication Warnings add warnings about various conditions +that may indicate attempts to spoof the mail system, +such as using an non-standard queue directory. +.ip QueueDirectory=\fIdir\fP +[Q] +Use the named +.i dir +as the queue directory. +.ip QueueFactor=\fIfactor\fP +[q] +Use +.i factor +as the multiplier in the map function +to decide when to just queue up jobs rather than run them. +This value is divided by the difference between the current load average +and the load average limit +(\c +.b QueueLA +option) +to determine the maximum message priority +that will be sent. +Defaults to 600000. +.ip QueueLA=\fILA\fP +[x] +When the system load average exceeds +.i LA , +just queue messages +(i.e., don't try to send them). +Defaults to 8. +.ip QueueSortOrder=\fIalgorithm\fP +[no short name] +Sets the +.i algorithm +used for sorting the queue. +Only the first character of the value is used. +Legal values are +.q host +(to order by the name of the first host name of the first recipient) +and +.q priority +(to order strictly by message priority). +Host ordering makes better use of the connection cache, +but may tend to process low priority messages +that go to a single host +over high priority messages that go to several hosts; +it probably shouldn't be used on slow network links. +Priority ordering is the default. +.ip ResolverOptions=\fIoptions\fP +[I] +Set resolver options. +Values can be set using +.b + \c +.i flag +and cleared using +.b \- \c +.i flag ; +the +.i flag s +can be +.q debug , +.q aaonly , +.q usevc , +.q primary , +.q igntc , +.q recurse , +.q defnames , +.q stayopen , +or +.q dnsrch . +The string +.q HasWildcardMX +(without a +.b + +or +.b \- ) +can be specified to turn off matching against MX records +when doing name canonifications. +.b N.B. +Prior to 8.7, +this option indicated that the name server be responding +in order to accept addresses. +This has been replaced by checking to see +if the +.q dns +method is listed in the service switch entry for the +.q hosts +service. +.ip SmtpGreetingMessage=\fImessage\fP +[$e macro] +The message printed when the SMTP server starts up. +Defaults to +.q "$j Sendmail $v ready at $b". +.ip Timeout.\fItype\fP=\|\fItimeout\fP +[r; subsumes old T option as well] +Set timeout values. +The actual timeout is indicated by the +.i type . +The recognized timeouts and their default values, and their +minimum values specified in RFC

(\(dg) +apply to client SMTP. +If the message is submitted using the +.sm NOTIFY +.sm SMTP +extension, +warning messages will only be sent if +.sm NOTIFY=DELAY +is specified. +The queuereturn and queuewarn timeouts +can be further qualified with a tag based on the Precedence: field +in the message; +they must be one of +.q urgent +(indicating a positive non-zero precedence) +.q normal +(indicating a zero precedence), or +.q non-urgent +(indicating negative precedences). +For example, setting +.q Timeout.queuewarn.urgent=1h +sets the warning timeout for urgent messages only +to one hour. +The default if no precedence is indicated +is to set the timeout for all precedences. +.ip RecipientFactor=\fIfact\fP +[y] +The indicated +.i fact or +is added to the priority (thus +.i

+[w] +If this system is the +.q best +(that is, lowest preference) +MX for a given host, +its configuration rules should normally detect this situation +and treat that condition specially +by forwarding the mail to a UUCP feed, +treating it as local, +or whatever. +However, in some cases (such as Internet firewalls) +you may want to try to connect directly to that host +as though it had no MX records at all. +Setting this option causes +.i sendmail +to try this. +The downside is that errors in your configuration +are likely to be diagnosed as +.q "host unknown" +or +.q "message timed

Verbose +should +.i never +be set in the configuration file; +it is intended for command line use only. +.lp +All options can be specified on the command line using the +\-O or \-o flag, +but most will cause +.i sendmail +to relinquish its setuid permissions. +The options that will not cause this are +MinFreeBlocks [b], +DeliveryMode [d], +ErrorMode [e], +IgnoreDots [i], +LogLevel [L], +MeToo [m], +OldStyleHeaders [o], +PrivacyOptions [p], +Timeouts [r], +SuperSafe [s], +Verbose [v], +CheckpointInterval [C], +and +SevenBitInput [7]. +Also, M (define macro) when defining the r or s macros

+\fBP\fP\fIname\fP\fB=\fP\fInum\fP +.)b +When the +.i name +is found in a +.q Precedence: +field, +the message class is set to +.i num . +Higher numbers mean higher precedence. +Numbers less than zero +have the special property +that if an error occurs during processing +the body of the message will not be returned; +this is expected to be used for +.q "bulk" +mail such as through mailing lists. +The default precedence is zero. +For example, +our list of precedences is: +.(b +Pfirst-class=0 +Pspecial-delivery=100 +Plist=\-30 +Pbulk=\-60 +Pjunk=\-100 +.)b +People writing mailing list exploders +are encouraged to use +.q "Precedence: list" . +Older versions of +.i sendmail +(which discarded all error returns for negative precedences) +didn't recognize this name, giving it a default precedence of zero. +This allows list maintainers to see error returns +on both old and new versions of +.i sendmail . +.sh 2 "V \*- Configuration Version Level" +.pp +To provide compatibility with old configuration files, +the +.b V +line has been added to define some very basic semantics +of the configuration file. +These are not intended to be long term supports; +rather, they describe compatibility features +which will probably be removed in future releases. +.pp +.b N.B.: +these version +.i levels +have nothing +to do with the version +.i number +on the files. +For example, +as of this writing +version 8 config files +(specifically, 8.7) +used version level 6 configurations. +.pp +.q Old +configuration files are defined as version level one. +Version level two files make the following changes: +.np +Host name canonification ($[ ... $]) +appends a dot if the name is recognized; +this gives the config file a way of finding out if anything matched. +(Actually, this just initializes the +.q host +map with the +.q \-a. +flag \*- you can reset it to anything you prefer +by declaring the map explicitly.) +.np +Default host name extension is consistent throughout processing; +version level one configurations turned off domain extension +(that is, adding the local domain name) +during certain points in processing. +Version level two configurations are expected to include a trailing dot +to indicate that the name is already canonical. +.np +Local names that are not aliases +are passed through a new distinguished ruleset five; +this can be used to append a local relay. +This behaviour can be prevented by resolving the local name +with an initial `@'. +That is, something that resolves to a local mailer and a user name of +.q vikki +will be passed through ruleset five, +but a user name of +.q @vikki +will have the `@' stripped, +will not be passed through ruleset five, +but will otherwise be treated the same as the prior example. +The expectation is that this might be used to implement a policy +where mail sent to +.q vikki +was handled by a central hub, +but mail sent to +.q vikki@localhost +was delivered directly. +.pp +Version level three files +allow # initiated comments on all lines. +Exceptions are backslash escaped # marks +and the $# syntax. +.pp +Version level four configurations +are completely equivalent to level three +for historical reasons. +.pp +Version level five configuration files +change the default definition of +.b $w +to be just the first component of the hostname. +.pp +Version level six configuration files +change many of the local processing options +(such as aliasing and matching the beginning of the address for +`|' characters) +to be mailer flags; +this allows fine-grained control over the special local processing. +Level six configuration files may also use long option names. +The +.b ColonOkInAddr +option (to allow colons in the local-part of addresses) +defaults +.b on +for lower numbered configuration files; +the configuration file requires some additional intelligence +to properly handle the RFC 822 group construct. +.pp +The +.b V +line may have an optional +.b / \c +.i vendor +to indicate that this configuration file uses modifications +specific to a particular vendor\**. +.(f +\**And of course, vendors are encouraged to add themselves +to the list of recognized vendors by editing the routine +.i setvendor +in +.i conf.c . +Please send e-mail to sendmail@CS.Berkeley.EDU +to register your vendor dialect. +.)f +You may use +.q /Berkeley +to emphasize that this configuration file +uses the Berkeley dialect of +.i sendmail . +.sh 2 "K \*- Key File Declaration" +.pp +Special maps can be defined using the line: +.(b +Kmapname mapclass arguments +.)b +The +.i mapname +is the handle by which this map is referenced in the rewriting rules. +The +.i mapclass +is the name of a type of map; +these are compiled in to +.i sendmail . +The +.i arguments +are interpreted depending on the class; +typically, +there would be a single argument naming the file containing the map. +.pp +Maps are referenced using the syntax: +.(b +$( \fImap\fP \fIkey\fP $@ \fIarguments\fP $: \fIdefault\fP $) +.)b +where either or both of the +.i arguments +or +.i default +portion may be omitted. +The +.i "$@ arguments" +may appear more than once. +The indicated +.i key +and +.i arguments +are passed to the appropriate mapping function. +If it returns a value, it replaces the input. +If it does not return a value and the +.i default +is specified, the +.i default +replaces the input. +Otherwise, the input is unchanged. +.pp +During replacement of either a map value or default +the string +.q %\fIn\fP +(where +.i n +is a digit) +is replaced by the corresponding +.i argument . +Argument zero +is always the database key. +For example, the rule +.(b +.ta 1.5i +R$\- ! $+ $: $(uucp $1 $@ $2 $: %1 @ %0 . UUCP $) +.)b +Looks up the UUCP name in a (user defined) UUCP map; +if not found it turns it into +.q \&.UUCP +form. +The database might contain records like: +.(b +decvax %1@%0.DEC.COM +research %1@%0.ATT.COM +.)b +.pp +The built in map with both name and class +.q host +is the host name canonicalization lookup. +Thus, +the syntax: +.(b +$(host \fIhostname\fP$) +.)b +is equivalent to: +.(b +$[\fIhostname\fP$] +.)b +.pp +There are many defined classes. +.ip dbm +Database lookups using the ndbm(3) library. +.i Sendmail +must be compiled with +.b NDBM +defined. +.ip btree +Database lookups using the btree interface to the Berkeley db(3) library. +.i Sendmail +must be compiled with +.b NEWDB +defined. +.ip hash +Database lookups using the hash interface to the Berkeley db(3) library. +.i Sendmail +must be compiled with +.b NEWDB +defined. +.ip nis +NIS lookups. +.i Sendmail +must be compiled with +.b NIS +defined. +.ip nisplus +NIS+ lookups. +.i Sendmail +must be compiled with +.b NISPLUS +defined. +The argument is the name of the table to use for lookups, +and the +.b \-k +and +.b \-v +flags may be used to set the key and value columns respectively. +.ip hesiod +Hesiod lookups. +.i Sendmail +must be compiled with +.b HESIOD +defined. +.ip netinfo +NeXT NetInfo lookups. +.i Sendmail +must be compiled with +.b NETINFO +defined. +.ip text +Text file lookups. +The format of the text file is defined by the +.b \-k +(key field number), +.b \-v +(value field number), +and +.b \-z +(field delimiter) +flags. +.ip stab +Internal symbol table lookups. +Used internally for aliasing. +.ip implicit +Really should be called +.q alias +\(em this is used to get the default lookups +for alias files, +and is the default if no class is specified for alias files. +.ip user +Looks up users using +.i getpwnam (3). +The +.b \-v +flag can be used to specify the name of the field to return +(although this is normally used only to check the existence +of a user). +.ip host +Canonifies host domain names. +Given a host name it calls the name server +to find the canonical name for that host. +.ip sequence +The arguments on the `K' line are a list of maps; +the resulting map searches the argument maps in order +until it finds a match for the indicated key. +For example, if the key definition is: +.(b +Kmap1 ... +Kmap2 ... +Kseqmap sequence map1 map2 +.)b +then a lookup against +.q seqmap +first does a lookup in map1. +If that is found, it returns immediately. +Otherwise, the same key is used for map2. +.ip switch +Much like the +.q sequence +map except that the order of maps is determined by the service switch. +The argument is the name of the service to be looked up; +the values from the service switch are appended to the map name +to create new map names. +For example, consider the key definition: +.(b +Kali switch aliases +.)b +together with the service switch entry: +.(b +aliases nis files +.)b +This causes a query against the map +.q ali +to search maps named +.q ali.nis +and +.q ali.files +in that order. +.ip dequote +Strip double quotes (") from a name. +It does not strip backslashes, +and will not strip quotes if the resulting string +would contain unscannable syntax +(that is, basic errors like unbalanced angle brackets; +more sophisticated errors such as unknown hosts are not checked). +The intent is for use when trying to accept mail from systems such as +DECnet +that routinely quote odd syntax such as +.(b +"49ers::ubell" +.)b +A typical usage is probably something like: +.(b +Kdequote dequote + +\&... + +R$\- $: $(dequote $1 $) +R$\- $+ $: $>3 $1 $2 +.)b +Care must be taken to prevent unexpected results; +for example, +.(b +"|someprogram < input > output" +.)b +will have quotes stripped, +but the result is probably not what you had in mind. +Fortunately these cases are rare. +.pp +Most of these accept as arguments the same optional flags +and a filename +(or a mapname for NIS; +the filename is the root of the database path, +so that +.q .db +or some other extension appropriate for the database type +will be added to get the actual database name). +Known flags are: +.ip "\-o" +Indicates that this map is optional \*- that is, +if it cannot be opened, +no error is produced, +and +.i sendmail +will behave as if the map existed but was empty. +.ip "\-N, \-O" +If neither +.b \-N +or +.b \-O +are specified, +.i sendmail +uses an adaptive algorithm to decide whether or not to look for null bytes +on the end of keys. +It starts by trying both; +if it finds any key with a null byte it never tries again without a null byte +and vice versa. +If +.b \-N +is specified it never tries without a null byte and +if +.b \-O +is specified it never tries with a null byte. +Setting one of +these can speed matches but are never necessary. +If both +.b \-N +and +.b \-O +are specified, +.i sendmail +will never try any matches at all \(em +that is, everything will appear to fail. +.ip "\-a\fIx\fP" +Append the string +.i x +on successful matches. +For example, the default +.i host +map appends a dot on successful matches. +.ip "\-f" +Do not fold upper to lower case before looking up the key. +.ip "\-m" +Match only (without replacing the value). +If you only care about the existence of a key and not the value +(as you might when searching the NIS map +.q hosts.byname +for example), +this flag prevents the map from substituting the value. +However, +The \-a argument is still appended on a match, +and the default is still taken if the match fails. +.ip "\-k\fIkeycol\fP" +The key column name (for NIS+) or number +(for text lookups). +.ip "\-v\fIvalcol\fP" +The value column name (for NIS+) or number +(for text lookups). +.ip "\-z\fIdelim\fP" +The column delimiter (for text lookups). +It can be a single character or one of the special strings +.q \|\en +or +.q \|\et +to indicate newline or tab respectively. +If omitted entirely, +the column separator is any sequence of whitespace. +.ip "\-s\fIspacesub\fP +For the dequote map only, +the character to use to replace space characters +after a successful dequote. +.pp +The +.i dbm +map appends the strings +.q \&.pag +and +.q \&.dir +to the given filename; +the two +.i db -based +maps append +.q \&.db . +For example, the map specification +.(b +Kuucp dbm \-o \-N /usr/lib/uucpmap +.)b +specifies an optional map named +.q uucp +of class +.q dbm ; +it always has null bytes at the end of every string, +and the data is located in +/usr/lib/uucpmap.{dir,pag}. +.pp +The program +.i makemap (8) +can be used to build any of the three database-oriented maps. +It takes the following flags: +.ip \-f +Do not fold upper to lower case in the map. +.ip \-N +Include null bytes in keys. +.ip \-o +Append to an existing (old) file. +.ip \-r +Allow replacement of existing keys; +normally, re-inserting an existing key is an error. +.ip \-v +Print what is happening. +.lp +The +.i sendmail +daemon does not have to be restarted to read the new maps +as long as you change them in place;

+mail sent to a specific machine should ignore these defaults. +.pp +When mail is sent, +the name of the sending user is looked up in the database. +If that user has a +.q mailname +record, +the value of that record is used as their outgoing name. +For example, I might have a record: +.(b +eric:mailname Eric.Allman@CS.Berkeley.EDU +.)b +This would cause my outgoing mail to be sent as Eric.Allman. +.pp +If a +.q maildrop +is found for the user, +but no corresponding +.q mailname +record exists, +the record +.q :default:mailname +is consulted. +If present, this is the name of a host to override the local host. +For example, in our case we would set it to +.q CS.Berkeley.EDU . +The effect is that anyone known in the database +gets their outgoing mail stamped as +.q user@CS.Berkeley.EDU , +but people not listed in the database use the local hostname. +.sh 3 "Creating the database\**" +.(f +\**These instructions are known to be incomplete. +A future version of the user database is planned +including things such as finger service \*- and good documentation. +.)f +.pp +The user database is built from a text file +using the +.i makemap +utility +(in the distribution in the makemap subdirectory). +The text file is a series of lines corresponding to userdb records;

+usually +.q _avenrun +or +.q avenrun ). +.sh 2 "Configuration in src/conf.c" +.pp +The following changes can be made in conf.c. +.sh 3 "Built-in Header Semantics" +.pp +Not all header semantics are defined in the configuration file. +Header lines that should only be included by certain mailers +(as well as other more obscure semantics) +must be specified in the +.i HdrInfo +table in +.i conf.c . +This table contains the header name +(which should be in all lower case) +and a set of header control flags (described below), +The flags are: +.ip H_ACHECK +Normally when the check is made to see if a header line is compatible +with a mailer, +.i sendmail +will not delete an existing line. +If this flag is set, +.i sendmail +will delete +even existing header lines. +That is, +if this bit is set and the mailer does not have flag bits set +that intersect with the required mailer flags +in the header definition in +sendmail.cf, +the header line is +.i always +deleted. +.ip H_EOH +If this header field is set, +treat it like a blank line, +i.e., +it will signal the end of the header +and the beginning of the message text. +.ip H_FORCE +Add this header entry +even if one existed in the message before. +If a header entry does not have this bit set, +.i sendmail +will not add another header line if a header line +of this name already existed. +This would normally be used to stamp the message +by everyone who handled it. +.ip H_TRACE +If set, +this is a timestamp +(trace) +field. +If the number of trace fields in a message +exceeds a preset amount +the message is returned +on the assumption that it has an aliasing loop. +.ip H_RCPT +If set, +this field contains recipient addresses. +This is used by the +.b \-t +flag to determine who to send to +when it is collecting recipients from the message. +.ip H_FROM +This flag indicates that this field +specifies a sender. +The order of these fields in the +.i HdrInfo +table specifies +.i sendmail 's +preference +for which field to return error messages to. +.ip H_ERRORSTO +Addresses in this header should receive error messages. +.ip H_CTE +This header is a Content-Transfer-Encoding header. +.ip H_CTYPE +This header is a Content-Type header. +.ip H_STRIPVAL +Strip the value from the header (for Bcc:). +.nr ii 5n +.lp +Let's look at a sample +.i HdrInfo +specification: +.(b +.ta 4n +\w'"content-transfer-encoding", 'u +struct hdrinfo HdrInfo[] = +\&{ + /* originator fields, most to least significant */ + "resent-sender", H_FROM, + "resent-from", H_FROM, + "sender", H_FROM, + "from", H_FROM, + "full-name", H_ACHECK, + "errors-to", H_FROM\^|\^H_ERRORSTO, + /* destination fields */ + "to", H_RCPT, + "resent-to", H_RCPT, + "cc", H_RCPT, + "bcc", H_RCPT\^|\^H_STRIPVAL, + /* message identification and control */ + "message", H_EOH, + "text", H_EOH, + /* trace fields */ + "received", H_TRACE\^|\^H_FORCE, + /* miscellaneous fields */ + "content-transfer-encoding", H_CTE, + "content-type", H_CTYPE, + + NULL, 0, +}; +.)b +This structure indicates that the +.q To: , +.q Resent-To: , +and +.q Cc: +fields +all specify recipient addresses. +Any +.q Full-Name: +field will be deleted unless the required mailer flag +(indicated in the configuration file) +is specified. +The +.q Message: +and +.q Text: +fields will terminate the header; +these are used by random dissenters around the network world. +The +.q Received: +field will always be added, +and can be used to trace messages. +.pp +There are a number of important points here. +First, +header fields are not added automatically just because they are in the +.i HdrInfo +structure; +they must be specified in the configuration file +in order to be added to the message. +Any header fields mentioned in the configuration file but not +mentioned in the +.i HdrInfo +structure have default processing performed; +that is, +they are added unless they were in the message already. +Second, +the +.i HdrInfo +structure only specifies cliched processing; +certain headers are processed specially by ad hoc code +regardless of the status specified in +.i HdrInfo . +For example, +the +.q Sender: +and +.q From: +fields are always scanned on ARPANET mail +to determine the sender\**; +.(f +\**Actually, this is no longer true in SMTP; +this information is contained in the envelope. +The older ARPANET protocols did not completely distinguish +envelope from header. +.)f +this is used to perform the +.q "return to sender" +function. +The +.q "From:" +and +.q "Full-Name:" +fields are used to determine the full name of the sender +if possible; +this is stored in the macro +.b $x +and used in a number of ways. +.sh 3 "Restricting Use of Email" +.pp +If it is necessary to restrict mail through a relay, +the +.i checkcompat +routine can be modified. +This routine is called for every recipient address. +It returns an exit status +indicating the status of the message. +The status +.sm EX_OK +accepts the address, +.sm EX_TEMPFAIL +queues the message for a later try, +and other values +(commonly +.sm EX_UNAVAILABLE ) +reject the message. +It is up to +.i checkcompat +to print an error message +(using +.i usrerr ) +if the message is rejected. +For example, +.i checkcompat +could read: +.(b +.re +.sz -1 +.ta 4n +4n +4n +4n +4n +4n +4n +int +checkcompat(to, e) + register ADDRESS *to; + register ENVELOPE *e; +\&{ + register STAB *s; + + s = stab("private", ST_MAILER, ST_FIND); + if (s != NULL && e\->e_from.q_mailer != LocalMailer && + to->q_mailer == s->s_mailer) + { + usrerr("No private net mail allowed through this machine");

+ } + return (EX_OK); +} +.sz +.)b +This would reject messages greater than 50000 bytes +unless they were local. +The +.i EF_NORETURN +flag can be set in +.i e\(->e_flags +to suppress the return of the actual body +of the message in the error return. +The actual use of this routine is highly dependent on the +implementation, +and use should be limited. +.sh 3 "Load Average Computation" +.pp +The routine +.i getla +should return an approximation of the current system load average +as an integer. +There are several versions included on compilation flags +as described above. +.sh 3 "New Database Map Classes" +.pp +New key maps can be added by creating a class initialization function +and a lookup function. +These are then added to the routine +.i setupmaps. +.pp +The initialization function is called as +.(b +\fIxxx\fP_map_init(MAP *map, char *mapname, char *args) +.)b +The +.i map +is an internal data structure. +The +.i mapname +is the name of the map (used for error messages). +The +.i args +is a pointer to the rest of the configuration file line; +flags and filenames can be extracted from this line. +The initialization function must return +.sm TRUE +if it successfully opened the map, +.sm FALSE +otherwise. +.pp +The lookup function is called as +.(b +\fIxxx\fP_map_lookup(MAP *map, char buf[], int bufsize, char **av, int *statp) +.)b +The +.i map +defines the map internally. +The parameters +.i buf +and +.i bufsize +have the input key. +This may be (and often is) used destructively. +The +.i av +is a list of arguments passed in from the rewrite line. +The lookup function should return a pointer to the new value. +IF the map lookup fails, +.i *statp +should be set to an exit status code; +in particular, it should be set to +.sm EX_TEMPFAIL +if recovery is to be attempted by the higher level code. +.sh 3 "Queueing Function" +.pp +The routine +.i shouldqueue +is called to decide if a message should be queued +or processed immediately. +Typically this compares the message priority to the current load average. +The default definition is: +.(b +bool +shouldqueue(pri, ctime) + long pri; + time_t ctime; +{ + if (CurrentLA < QueueLA) + return (FALSE); + return (pri > (QueueFactor / (CurrentLA \- QueueLA + 1))); +} +.)b +If the current load average +(global variable +.i CurrentLA , +which is set before this function is called) +is less than the low threshold load average +(option +.b x , +variable +.i QueueLA ), +.i shouldqueue +returns +.sm FALSE +immediately +(that is, it should +.i not +queue). +If the current load average exceeds the high threshold load average +(option +.b X , +variable +.i RefuseLA ), +.i shouldqueue +returns +.sm TRUE +immediately. +Otherwise, it computes the function based on the message priority, +the queue factor +(option +.b q , +global variable +.i QueueFactor ), +and the current and threshold load averages. +.pp +An implementation wishing to take the actual age of the message into account +can also use the +.i ctime +parameter, +which is the time that the message was first submitted to +.i sendmail . +Note that the +.i pri +parameter is already weighted +by the number of times the message has been tried +(although this tends to lower the priority of the message with time); +the expectation is that the +.i ctime +would be used as an +.q "escape clause" +to ensure that messages are eventually processed. +.sh 3 "Refusing Incoming SMTP Connections" +.pp +The function +.i refuseconnections +returns +.sm TRUE +if incoming SMTP connections should be refused. +The current implementation is based exclusively on the current load average +and the refuse load average option +(option +.b X , +global variable +.i RefuseLA ): +.(b +bool +refuseconnections() +{ + return (CurrentLA >= RefuseLA); +} +.)b +A more clever implementation +could look at more system resources. +.sh 3 "Load Average Computation" +.pp +The routine +.i getla +returns the current load average (as a rounded integer). +The distribution includes several possible implementations. +If you are porting to a new environment +you may need to add some new tweaks.\** +.(f +\**If you do, please send updates to +sendmail@CS.Berkeley.EDU. +.)f +.sh 2 "Configuration in src/daemon.c" +.pp +The file +.i src/daemon.c +contains a number of routines that are dependent +on the local networking environment. +The version supplied assumes you have BSD style sockets. +.pp +In previous releases, +we recommended that you modify the routine +.i maphostname +if you wanted to generalize +.b $[ +\&...\& +.b $] +lookups. +We now recommend that you create a new keyed map instead. +.sh 1 "CHANGES IN VERSION 8" +.pp +The following summarizes changes +since the last commonly available version of +.i sendmail +(5.67). +For a detailed list, +consult the file +RELEASE_NOTES +in the root directory of the +.i sendmail +distribution. +.sh 2 "Connection Caching" +.pp +Instead of closing SMTP connections immediately, +those connections are cached for possible future use. +The advent of MX records made this effective for mailing lists; +in addition, +substantial performance improvements can be expected for queue processing. +.sh 2 "MX Piggybacking" +.pp +If two hosts with different names in a single message +happen to have the same set of MX hosts, +they can be sent in the same transaction. +Version 8 notices this and tries to batch the messages. +.sh 2 "RFC 1123 Compliance" +.pp +A number of changes have been made to make +.i sendmail +.q "conditionally compliant" +(that is, +.i sendmail +satisfies all of the +.q MUST +clauses and most but not all of the +.q SHOULD +clauses in RFC 1123). +.pp +The major areas of change are (numbers are RFC 1123 section numbers): +.nr ii \w'5.3.1.1\0\0'u +.ip 5.2.7 +Response to RCPT command is fast. +.ip 5.2.8 +Numeric IP addresses are logged in Received: lines. +.ip 5.2.17 +Self domain literal is properly handled. +.ip 5.3.2 +Better control over individual timeouts. +.ip 5.3.3 +Error messages are sent as +.q From:<> . +.ip 5.3.3 +Error messages are never sent to +.q <> . +.ip 5.3.3 +Route-addrs are pruned. +.lp +The areas in which +.i sendmail +is not +.q "unconditionally compliant" +are: +.ip 5.2.6 +.i Sendmail +does do header munging. +.ip 5.2.10 +.i Sendmail +doesn't always use the exact SMTP message text +as listed in RFC 821. +.ip 5.3.1.1 +.i Sendmail +doesn't guarantee only one connect for each host in queue runs. +.ip 5.3.1.1 +.i Sendmail +doesn't always provide adequate concurrency limits. +.sh 2 "Extended SMTP Support" +.pp +Version 8 includes both sending and receiving support for Extended +SMTP support as defined by RFC 1651 (basic) and RFC 1653 (SIZE); +and limited support for RFC 1652 (BODY). +.sh 2 "Eight-Bit Clean" +.pp +Previous versions of +.i sendmail +used the 0200 bit for quoting. +This version avoids that use. +However, for compatibility with RFC 822, +you can set option `7' to get seven bit stripping. +.pp +Individual mailers can still produce seven bit output using the +`7' mailer flag. +.sh 2 "User Database" +.pp +The user database is an as-yet experimental attempt +to provide unified large-site name support. +We are installing it at Berkeley; +future versions may show significant modifications. +.sh 2 "Improved BIND Support" +.pp +The BIND support, +particularly for MX records, +had a number of annoying +.q features +which have been removed in this release. +In particular, +these more tightly bind (pun intended) the name server to +.i sendmail , +so that the name server resolution rules are incorporated directly into +.b sendmail . +.sh 2 "Keyed Files" +.pp +Generalized keyed files is an idea taken directly from +.sm IDA +.i sendmail +(albeit with a completely different implementation). +They can be useful on large sites. +.pp +Version 8 also understands YP. +.sh 2 "Multi-Word Classes" +.pp +Classes can now be multiple words. +For example, +.(b +CShofmann.CS.Berkeley.EDU +.)b +allows you to match the entire string +.q hofmann.CS.Berkeley.EDU +using the single construct +.q $=S . +.sh 2 "Deferred Macro Expansion" +.pp +The +.b $& \c +.i x +construct has been adopted from +.sm IDA . +.sh 2 "IDENT Protocol Support" +.pp +The IDENT protocol as defined in RFC 1413 is supported. +.sh 2 "Parsing Bug Fixes" +.pp +A number of small bugs having to do with things like +backslash-escaped quotes inside of comments +have been fixed. +.sh 2 "Separate Envelope/Header Processing" +.pp +Since the From: line is passed in separately from the envelope sender, +these have both been made visible; +the +.b $g +macro is set to the envelope sender during processing +of mailer argument vectors +and the header sender during processing of headers. +.pp +It is also possible to specify separate per-mailer +envelope and header processing. +The +.b S enderRWSet +and +.b R ecipientRWset +arguments for mailers +can be specified as +.i envelope/header +to give different rewritings for envelope versus header addresses. +.sh 2 "Owner-List Propagates to Envelope" +.pp +When an alias has an associated owner\-list name, +that alias is used to change the envelope sender address. +This will cause downstream errors to be returned to that owner. +.sh 2 "Dynamic Header Allocation" +.pp +The fixed size limit on header lines has been eliminated. +.sh 2 "New Command Line Flags" +.pp +The +.b \-B +flag has been added to pass in body type information. +.pp +The +.b \-p +flag has been added +to pass in protocol information. +.pp +The +.b \-X +flag has been added +to allow logging of all protocol in and out of +.i sendmail +for debugging. +.pp +The +.b \-O +flag simplies setting long-form options. +.sh 2 "Enhanced Command Line Flags" +.pp +The +.b \-q +flag can limit limit a queue run to specific recipients, senders, or queue ids +using +.b \-qR\c +.i substring , +.b \-qS\c +.i substring , +or +.b \-qI\c +.i substring +respectively. +.sh 2 "New and Old Configuration Line Types" +.pp +The +.b K +line has been added to declare database maps. +.pp +The +.b V +line has been added to declare the configuration version level. +.pp +The +.b M +line has a +.q D= +field that lets you change into a temporary directory while that mailer +is running. +It also has a +.q U= +field to allow you to set the user and group id to be used +when running the mailer. +.sh 2 "New Options" +.pp +Several new options have been added, +many to support new features, +others to allow tuning that was previously available +only by recompiling. +They are described in detail in Section 5.1.5. +Briefly, +.nr ii 0.5i +.ip b +Insist on a minimum number of disk blocks. +.ip C +Set checkpoint interval. +.ip E +Default error message. +.ip G +Enable GECOS matching. +.ip h +Maximum hop count. +.ip j +Send errors in MIME-encapsulated format. +.ip J +Forward file path. +.ip k +Connection cache size +.ip K +Connection cache lifetime. +.ip l +Enable Errors-To: header. +These headers violate RFC 1123; +this option is included to provide back compatibility +with old versions of +.i sendmail . +.ip O +Set incoming SMTP daemon options, such as an alternate SMTP port. +.ip p +Privacy options. +.ip R +Don't prune route-addrs. +.ip U +User database spec. +.ip V +Fallback +.q MX +host. +.ip w +.q "Best MX" +handling technique. +.ip 7 +Do not run eight bit clean. +.ip 8 +Eight bit data handling mode. +.sh 2 "Extended Options" +.pp +The +.b r +(read timeout), +.b I +(use BIND), +and +.b T +(queue timeout) +options have been extended to pass in more information. +.sh 2 "New Mailer Flags" +.pp +Several new mailer flags have been added. +.ip a +Try to use ESMTP when creating a connection. +If this is not set, +.i sendmail +will still try if the other end hints that it knows about ESMTP +in its greeting message; +this flag says to try even if it doesn't hint. +If the EHLO (extended hello) +command fails, +.i sendmail +falls back to old SMTP. +.ip A +Try the user part of addresses for this mailer as aliases. +.ip b +Ensure that there is a blank line at the end of all messages. +.ip c +Strip all comments from addresses; +this should only be used as a last resort +when dealing with cranky mailers. +.ip g +Never use the null sender as the envelope sender, +even when running SMTP. +Although this violates RFC 1123, +it may be necessary when you must deal with some obnoxious old hosts. +.ip k +Turn off the loopback check in the HELO protocol; +doing this may cause mailer loops. +.ip o +Always run the mailer as the recipient of the message. +.ip w +This user should have a passwd file entry. +.ip 5 +Try ruleset 5 if no local aliases. +.ip 7 +Strip all output to 7 bits. +.ip : +Check for :include: files. +.ip | +Check for |program addresses. +.ip / +Check for /file addresses. +.ip @ +Check this user against the user database. +.sh 2 "Long Option Names" +.pp +All options can be specified using long names, +and some new options can only be specified with long names. +.sh 2 "New Pre-Defined Macros" +.pp +The following macros are pre-defined: +.ip $k +The UUCP node name, +nominally from +.i uname (2) +call. +.ip $m +The domain part of our full hostname. +.ip $_ +The RFC 1413-provided sender address. +.sh 2 "New LHS Token" +.pp +Version 8 allows +.b $@ +on the Left Hand Side of an +.q R +line to match zero tokens. +This is intended to be used to match the null input. +.sh 2 "Bigger Defaults" +.pp +Version 8 allows up to 100 rulesets instead of 30. +It is recommended that rulesets 0\-9 be reserved for +.i sendmail 's +dedicated use in future releases. +.pp +The total number of MX records that can be used has been raised to 20. +.pp +The number of queued messages that can be handled at one time +has been raised from 600 to 1000. +.sh 2 "Different Default Tuning Parameters" +.pp +Version 8 has changed the default parameters +for tuning queue costs +to make the number of recipients more important +than the size of the message (for small messages). +This is reasonable if you are connected with reasonably fast links. +.sh 2 "Auto-Quoting in Addresses" +.pp +Previously, the +.q "Full Name <email address>" +syntax would generate incorrect protocol output +if +.q "Full Name" +had special characters such as dot. +This version puts quotes around such names. +.sh 2 "Symbolic Names On Error Mailer" +.pp +Several names have been built in to the $@ portion of the $#error +mailer. +.sh 2 "SMTP VRFY Doesn't Expand" +.pp +Previous versions of +.i sendmail +treated VRFY and EXPN the same. +In this version, +VRFY doesn't expand aliases or follow .forward files. +EXPN still does. +.pp +As an optimization, if you run with your default delivery mode being +queue-only or deliver-in-background, +the RCPT command will also not chase aliases and .forward files. +It will chase them when it processes the queue. +.sh 2 "[IPC] Mailers Allow Multiple Hosts" +.pp +When an address resolves to a mailer that has +.q [IPC] +as its +.q Path , +the $@ part (host name) +can be a colon-separated list of hosts instead of a single hostname. +This asks +.i sendmail +to search the list for the first entry that is available +exactly as though it were an MX record. +The intent is to route internal traffic through internal networks +without publishing an MX record to the net. +MX expansion is still done on the individual items. +.sh 2 "Aliases Extended" +.pp +The implementation has been merged with maps. +Among other things, +this supports NIS-based aliases. +.sh 2 "Portability and Security Enhancements" +.pp +A number of internal changes have been made to enhance portability. +.pp +Several fixes have been made to increase the paranoia factor. +.sh 2 "Miscellaneous Changes" +.pp +.i Sendmail +writes a +.i /etc/sendmail.pid +file with the current process id of the SMTP daemon. +.pp +Two people using the same program in their .forward file +are considered different +so that duplicate elimination doesn't delete one of them. +.pp +The +.i mailstats +program prints mailer names +and gets the location of the +.i sendmail.st +file from +.i /etc/sendmail.cf . +.pp +Many minor bugs have been fixed, such as handling of backslashes +inside of quotes. +.pp +A hook (ruleset 5) has been added +to allow rewriting of local addresses after aliasing. +.sh 1 "ACKNOWLEDGEMENTS" +.pp +I've worked on +.i sendmail +for many years, +and many employers have been remarkably patient +about letting me work on a large project +that was not part of my official job. +This includes time on the INGRES Project at +the University of California at Berkeley, +at Britton Lee, +and again on the Mammoth and Titan Projects at Berkeley. +.pp +Much of the second wave of improvements +should be credited to Bryan Costales of ICSI. +As he passed me drafts of his book on +.i sendmail +I was inspired to start working on things again. +Bryan was also available to bounce ideas off of. +.pp +Many, many people contributed chunks of code and ideas to +.i sendmail . +It has proven to be a group network effort. +Version 8 in particular was a group project. +The following people made notable contributions: +.(l +John Beck, Hewlett-Packard +Keith Bostic, CSRG, University of California, Berkeley +Andrew Cheng, Sun Microsystems +Michael J.

contributed code, +and many more have contributed ideas, comments, and encouragement. +I've tried to list them in the RELEASE_NOTES in the distribution directory. +I appreciate their contribution as well. +.pp +Special thanks are reserved for Michael Corrigan and Christophe Wolfhugel, +who besides being wonderful guinea pigs and contributors +have also consented to be added to the ``sendmail@CS.Berkeley.EDU'' list +and, by answering the bulk of the questions sent to that list, +have freed me up to do other work. +.++ A +.+c "COMMAND LINE FLAGS" +.ba 0 +.nr ii 1i +.pp +Arguments must be presented with flags before addresses. +The flags are: +.ip \-b\fIx\fP +Set operation mode to +.i x . +Operation modes are: +.(b +.ta 4n +m Deliver mail (default) +s Speak SMTP on input side +a\(dg ``Arpanet'' mode (get envelope sender information from header) +d Run as a daemon +t Run in test mode +v Just verify addresses, don't collect or deliver +i Initialize the alias database +p Print the mail queue +.)b +.(f +\(dgDeprecated. +.)f +.ip \-B\fItype\fP +Indicate body type. +.ip \-C\fIfile\fP +Use a different configuration file. +.i Sendmail +runs as the invoking user (rather than root) +when this flag is specified. +.ip \-d\fIlevel\fP +Set debugging level. +.ip "\-f\ \fIaddr\fP" +The sender's machine address is +.i addr . +.ip \-F\fIname\fP +Sets the full name of this user to +.i name . +.ip "\-h\ \fIcnt\fP" +Sets the +.q "hop count" +to +.i cnt . +This represents the number of times this message has been processed +by +.i sendmail +(to the extent that it is supported by the underlying networks). +.i Cnt +is incremented during processing, +and if it reaches +MAXHOP +(currently 30) +.i sendmail +throws away the message with an error. +.ip \-n +Don't do aliasing or forwarding. +.ip "\-r\ \fIaddr\fP" +An obsolete form of +.b \-f . +.ip \-o\fIx\|value\fP +Set option +.i x +to the specified +.i value . +These options are described in Section 5.6. +.ip \-O\fIoption\fP\fB=\fP\fIvalue\fP +Set +.i option +to the specified +.i value +(for long form option names). +These options are described in Section 5.6. +.ip \-M\fIx\|value +Set macro +.i x +to the specified +.i value . +.ip \-p\fIprotocol\fP +Set the sending protocol. +Programs are encouraged to set this. +The protocol field can be in the form +.i protocol \c +.b : \c +.i host +to set both the sending protocol and sending host. +For example, +.q \-pUUCP:uunet +sets the sending protocol to UUCP +and the sending host to uunet. +(Some existing programs use \-oM to set the r and s macros; +this is equivalent to using \-p.) +.ip \-q\fItime\fP +Try to process the queued up mail. +If the time is given, +a +.i sendmail +will run through the queue at the specified interval +to deliver queued mail; +otherwise, it only runs once. +.ip \-q\fIXstring\fP +Run the queue once, +limiting the jobs to those matching +.i Xstring . +The key letter +.i X +can be +.b I +to limit based on queue identifier, +.b R +to limit based on recipient, +or +.b S +to limit based on sender. +A particular queued job is accepted if one of the corresponding addresses +contains the indicated +.i string . +.ip \-t +Read the header for +.q To: , +.q Cc: , +and +.q Bcc: +lines, and send to everyone listed in those lists. +The +.q Bcc: +line will be deleted before sending. +Any addresses in the argument vector will be deleted +from the send list. +.ip "\-X \fIlogfile\fP" +Log all traffic in and out of +.i sendmail +in the indicated +.i logfile +for debugging mailer problems. +This produces a lot of data very quickly and should be used sparingly. +.pp +There are a number of options that may be specified as +primitive flags. +These are the e, i, m, and v options. +Also, +the f option +may be specified as the +.b \-s +flag. +.+c "QUEUE FILE FORMATS" +.pp +This appendix describes the format of the queue files. +These files live in the directory defined by the +.b Q +option in the +.i sendmail.cf +file, usually +.i /var/spool/mqueue +or +.i /usr/spool/mqueue . +.pp +All queue files have the name +\fIx\fP\|\fBf\fP\fIAAA99999\fP +where +.i AAA99999 +is the +.i id +for this message +and the +.i x +is a type. +The first letter of the id encodes the hour of the day +that the message was received by the system +(with A being the hour between midnight and 1:00AM). +All files with the same id collectively define one message. +.pp +The types are: +.nr ii 0.5i +.ip d +The data file. +The message body (excluding the header) is kept in this file. +.ip q +The queue control file. +This file contains the information necessary to process the job. +.ip t +A temporary file. +These are an image of the +.b qf +file when it is being rebuilt. +It should be renamed to a +.b qf +file very quickly. +.ip x +A transcript file, +existing during the life of a session +showing everything that happens +during that session. +.pp +The +.b qf +file is structured as a series of lines +each beginning with a code letter. +The lines are as follows: +.ip V +The version number of the queue file format, +used to allow new +.i sendmail +binaries to read queue files created by older versions. +Defaults to version zero. +Must be the first line of the file if present. +.ip H +A header definition. +There may be any number of these lines. +The order is important: +they represent the order in the final message. +These use the same syntax +as header definitions in the configuration file. +.ip C +The controlling address. +The syntax is +.q localuser:aliasname . +Recipient addresses following this line +will be flagged so that deliveries will be run as the +.i localuser +(a user name from the /etc/passwd file); +.i aliasname +is the name of the alias that expanded to this address +(used for printing messages). +.ip Q +The ``original recipient'', +specified by the ORCPT= field in an ESMTP transaction. +Used exclusively for Delivery Status Notifications. +It applies only to the immediately following `R' line. +.ip R +A recipient address. +This will normally be completely aliased, +but is actually realiased when the job is processed. +There will be one line +for each recipient. +Version 1 qf files +also include a leading colon-terminated list of flags, +which can be +`S' to return a message on successful final delivery, +`F' to return a message on failure, +`D' to return a message if the message is delayed, +`B' to indicate that the body should be returned, +`N' to suppress returning the body, +and +`P' to declare this as a ``primary'' (command line or SMTP-session) address. +.ip S +The sender address. +There may only be one of these lines. +.ip T +The job creation time. +This is used to compute when to time out the job. +.ip P +The current message priority. +This is used to order the queue. +Higher numbers mean lower priorities. +The priority changes +as the message sits in the queue. +The initial priority depends on the message class +and the size of the message. +.ip M +A message. +This line is printed by the +.i mailq +command, +and is generally used to store status information. +It can contain any text. +.ip F +Flag bits, represented as one letter per flag. +Defined flag bits are +.b r +indicating that this is a response message +and +.b w +indicating that a warning message has been sent +announcing that the mail has been delayed. +.ip N +The total number of delivery attempts. +.ip K +The time (as seconds since January 1, 1970) +of the last delivery attempt. +.ip I +The i-number of the data file; +this can be used to recover your mail queue +after a disastrous disk crash. +.ip $ +A macro definition. +The values of certain macros +(as of this writing, only +.b $r +and +.b $s ) +are passed through to the queue run phase. +.ip B +The body type. +The remainder of the line is a text string defining the body type. +If this field is missing, +the body type is assumed to be +.q "undefined" +and no special processing is attempted. +Legal values are +.q 7BIT +and +.q 8BITMIME . +.ip O +The original MTS value (from the ESMTP transaction). +For Deliver Status Notifications only. +.ip Z +The original envelope id (from the ESMTP transaction). +For Deliver Status Notifications only. +.pp +As an example, +the following is a queue file sent to +.q eric@mammoth.Berkeley.EDU +and +.q bostic@okeeffe.CS.Berkeley.EDU \**: +.(f +\**This example is contrived and probably inaccurate for your environment. +Glance over it to get an idea; +nothing can replace looking at what your own system generates. +.)f +.(b +P835771

This file is +intended as a supplement to the CERT advisory CA-93:16.sendmail.vulnerability, +and to the software, smrsh.c, written by Eric Allman. + + + +The smrsh(8) program is intended as a replacement for /bin/sh in the +program mailer definition of sendmail(8). This README file describes +the steps needed to compile and install smrsh. + +smrsh is a restricted shell utility that provides the ability to +specify, through a configuration, an explicit list of executable +programs. When used in conjunction with sendmail, smrsh effectively +limits sendmail's scope of program execution to only those programs +specified in smrsh's configuration. + +smrsh has been written with portability in mind, and uses traditional +Unix library utilities. As such, smrsh should compile on most +Unix C compilers. + + + +To compile smrsh.c, use the following command: + +host.domain% cc -o smrsh smrsh.c + +For machines that provide dynamic linking, it is advisable to compile +smrsh without dynamic linking. As an example with the Sun Microsystems +compiler, you should compile with the -Bstatic option. + +host.domain% cc -Bstatic -o smrsh smrsh.c + + +Choose a directory that smrsh will reside in. We will use the traditional +/usr/local/etc directory for the remainder of this document. + +As root, install smrsh in /usr/local/etc directory, with mode 511. + +host.domain# mv smrsh /usr/local/etc +host.domain# chmod 511 /usr/local/etc/smrsh + + + +Next, determine the list of commands that smrsh should allow sendmail +to run. This list of allowable commands can be determined by: + + 1. examining your /etc/aliases file, to indicate what commands + are being used by the system. + + 2. surveying your host's .forward files, to determine what + commands users have specified. + +See the man page for aliases(5) if you are unfamiliar with the format of +these specifications. Additionally, you should include in the list, +popular commands such as /usr/ucb/vacation. + +You should NOT include interpreter programs such as sh(1), csh(1), +perl(1), uudecode(1) or the stream editor sed(1) in your list of +acceptable commands. + + +You will next need to create the directory /usr/adm/sm.bin and populate +it with the programs that your site feels are allowable for sendmail +to execute. This directory is explicitly specified in the source +code for smrsh, so changing this directory must be accompanied with +a change in smrsh.c. + + +You will have to be root to make these modifications. + +After creating the /usr/adm/sm.bin directory, either copy the programs +to the directory, or establish links to the allowable programs from +/usr/adm/sm.bin. Change the file permissions, so that these programs +can not be modified by non-root users. If you use links, you should +ensure that the target programs are not modifiable. + +To allow the popular vacation(1) program by creating a link in the +/usr/adm/sm.bin directory, you should: + +host.domain# cd /usr/adm/sm.bin +host.domain# ln -s /usr/ucb/vacation vacation + + + + +After populating the /usr/adm/sm.bin directory, you can now configure +sendmail to use the restricted shell. Save the current sendmail.cf +file prior to modifying it, as a prudent precaution. + +Typically, the program mailer is defined by a single line in the +sendmail configuration file, sendmail.cf. This file is traditionally +found in the /etc, /usr/lib or /etc/mail directories, depending on +the UNIX vendor. + +If you are unsure of the location of the actual sendmail configuration +file, a search of the strings(1) output of the sendmail binary, will +help to locate it. + +In order to configure sendmail to use smrsh, you must modify the Mprog +definition in the sendmail.cf file, by replacing the /bin/sh specification +with /usr/local/etc/smrsh. + +As an example: + +In most Sun Microsystems' sendmail.cf files, the line is: +Mprog, P=/bin/sh, F=lsDFMeuP, S=10, R=20, A=sh -c $u + +which should be changed to: +Mprog, P=/usr/local/etc/smrsh, F=lsDFMeuP, S=10, R=20, A=sh -c $u + ^^^^^^^^^^^^^^^^^^^^ + +A more generic line may be: +Mprog, P=/bin/sh, F=lsDFM, A=sh -c $u + +and should be changed to; +Mprog, P=/usr/local/etc/smrsh, F=lsDFM, A=sh -c $u + + +After modifying the Mprog definition in the sendmail.cf file, if a frozen +configuration file is being used, it is essential to create a new one. +You can determine if you need a frozen configuration by discovering +if a sendmail.fc file currently exists in either the /etc/, /usr/lib, +or /etc/mail directories. The specific location can be determined using +a search of the strings(1) output of the sendmail binary. + +In order to create a new frozen configuration, if it is required: +host.domain# /usr/lib/sendmail -bz + +Now re-start the sendmail process. An example of how to do this on +a typical system follows: + +host.domain# /usr/bin/ps aux | /usr/bin/grep sendmail +root 130 0.0 0.0 168 0 ?

DO NOT USE MAKE !! to compile sendmail -- instead, use the +********************* "makesendmail" script located in the src +directory. It will find an appropriate Makefile, and create an +appropriate obj.* subdirectory so that multiplatform support +works easily. + +The Makefile is for the new (4.4BSD) Berkeley make and uses syntax +that is not recognized by older makes. It also has assumptions +about the 4.4 file system layout built in.

It also creates a +subdirectory per object format, so that multiarchitecture support is +easy. In general this should be all you need. However, if for some +reason this doesn't work (e.g., NeXT systems don't have the "uname" +command) you may have to set up your compile environment by hand. + +The "Makefile"s in these directories are from 4.4 BSD, and hence +really only work properly if you are on a 4.4 system. In particular, +they use new syntax that will not be recognized on old make programs, +and some of them do things like ``.include ../../Makefile.inc'' to +pick up some system defines. If you are getting sendmail separately, +these files won't be included in the distribution, as they are +outside of the sendmail tree. + +Instead, you should use one of the other Makefiles, such as +Makefile.SunOS for a SunOS system, and so forth. These should +work with the version of make that is appropriate for that +system. All other Makefiles are in the "src/Makefiles" subdirectory. +They use the version of make that is native for that system. These +are the Makefiles that I use, and they have "Berkeley quirks" in them. +I can't guarantee that they will work unmodified in your environment. +In particular, Many of them include -I/usr/sww/include/db and +-L/usr/sww/lib -- these are Berkeley's locations in the ``Software +Warehouse'' for the new database libraries, described below. You don't +have to remove these definitions if you don't have these directories, +but you may have to remove -DNEWDB from the DBMDEF definition. + +Please look for an appropriate Makefile before you start trying to +compile with Makefile or Makefile.dist. + +If you want to port the new Berkeley make, you can get it from +ftp.uu.net in the directory /systems/unix/bsd-sources/usr.bin/make. +Diffs and instructions for building this version of make under +SunOS 4.1.x are available on ftp.css.itd.umich.edu in +/pub/systems/sun/Net2-make-sun4.diff.Z. Diffs and instructions +for building this version of make under IBM AIX 3.2.4 are available +on ftp.uni-stuttgart.de in /sw/src/patches/bsd-make-rus-patches. +For Ultrix, try ftp.vix.com:~ftp/pub/patches/pmake-for-ultrix.Z. +Paul Southworth <pauls@umich.edu> published a description of porting +this make in comp.unix.bsd. + +The complete text of the Makefile.inc that is in the parent of the +sendmail directory is: + + # @(#)Makefile.inc 8.1 (Berkeley) 6/6/93 + + BINDIR?= /usr/sbin + + ++----------------------+ +| DATABASE DEFINITIONS | ++----------------------+ + +There are several database formats that can be used for the alias files +and for general maps. When used for alias files they interact in an +attempt to be back compatible. + +The three options are NEWDB (the new Berkeley DB package), NDBM (the +older DBM implementation -- the very old V7 implementation is no +longer supported), and NIS (Network Information Services). Used alone +these just include the support they indicate. [If you are using NEWDB, +get the latest version from FTP.CS.Berkeley.EDU in /ucb/4bsd/db.tar.Z +(or db.tar.gz). DO NOT use the version from the Net2 distribution! +However, if you are on BSD/386 or 386BSD-based systems, use the one +that already exists on your system. You may need to #define OLD_NEWDB +1 to do this.] + +[NOTE WELL: it is CRITICAL that you remove ndbm.o from libdb.a and +ndbm.h from the appropriate include directories if you want to get +ndbm support. These files OVERRIDE calls to ndbm routines -- in +particular, if you leave ndbm.h in, you can find yourself using +the new db package even if you don't define NEWDB.] + +If NEWDB and NDBM are defined (but not NIS), then sendmail will read +NDBM format alias files, but the next time a newaliases is run the +format will be converted to NEWDB; that format will be used forever +more. This is intended as a transition feature. [Note however that +the NEWDB library also catches and maps NDBM calls; you will have to +back out this feature to get this to work. See ``Quirks'' section +below for details.] + +If all three are defined and the name of the file includes the string +"/yp/", sendmail will rebuild BOTH the NEWDB and NDBM format alias +files. However, it will only read the NEWDB file; the NDBM format file +is used only by the NIS subsystem. + +If NDBM and NIS are defined (regardless of the definition of NEWDB), +and the filename includes the string "/yp/", sendmail adds the special +tokens "YP_LAST_MODIFIED" and "YP_MASTER_NAME", both of which are +required if the NDBM file is to be used as an NIS map. + +There is also preliminary support for NIS+ (-DNISPLUS), Hesiod +(-DHESIOD), and NetInfo (-DNETINFO). These have not been well +tested. + +All of -DNEWDB, -DNDBM, -DNIS, -DNISPLUS, -DHESIOD, and -DNETINFO are +normally defined in the DBMDEF line in the Makefile. + +If you define NEWDB or HESIOD you get the User Database (USERDB) +automatically. Generally you do want to have NEWDB for it to do +anything interesting. See above for getting the Berkeley "db" +package (i.e., NEWDB). There is no separate "user database" +package -- don't bother searching for it on the net. + + ++---------------+ +| COMPILE FLAGS | ++---------------+ + +Whereever possible, I try to make sendmail pull in the correct +compilation options needed to compile on various environments based on +automatically defined symbols. Some machines don't seem to have useful +symbols available, requiring that a compilation flag be defined in +the Makefile; see the Makefiles subdirectory for the supported +architectures. + +If you are a system to which sendmail has already been ported you +should not have to touch the following symbols. But if you are porting, +you may have to tweak the following compilation flags in conf.h in order +to get it to compile and link properly: + +SYSTEM5 Adjust for System V (not necessarily Release 4). +SYS5SIGNALS Use System V signal semantics -- the signal handler + is automatically dropped when the signal is caught. + If this is not set, use POSIX/BSD semantics, where the + signal handler stays in force until an exec or an + explicit delete. Implied by SYSTEM5. +SYS5SETPGRP Use System V setpgrp() semantics. Implied by SYSTEM5. +HASFCHMOD Define this to one if you have the fchmod(2) system call. + This improves security. +HASFLOCK Set this if you prefer to use the flock(2) system call + rather than using fcntl-based locking. Fcntl locking + has some semantic gotchas, but many vendor systems + also interface it to lockd(8) to do NFS-style locking. + Unfortunately, may vendors implementations of fcntl locking + is just plain broken (e.g., locks are never released, + causing your sendmail to deadlock; when the kernel runs + out of locks your system crashes). For this reason, I + recommend always defining this unless you are absolutely + certain that your fcntl locking implementation really works. +HASUNAME Set if you have the "uname" system call. Implied by + SYSTEM5. +HASUNSETENV Define this if your system library has the "unsetenv" + subroutine. +HASSETSID Define this if you have the setsid(2) system call. This + is implied if your system appears to be POSIX compliant. +HASINITGROUPS Define this if you have the initgroups(3) routine. +HASSETVBUF Define this if you have the setvbuf(3) library call. + If you don't, setlinebuf will be used instead. This + defaults on if your compiler defines __STDC__. +HASSETREUID Define this if you have setreuid(2) ***AND*** root can + use setreuid to change to an arbitrary user. This second + condition is not satisfied on AIX 3.x. You may find that + your system has setresuid(2), (for example, on HP-UX) in + which case you will also have to #define setreuid(r, e) + to be the appropriate call. Some systems (such as Solaris) + have a compatibility routine that doesn't work properly, + but may have "saved user ids" properly implemented so you + can ``#define setreuid(r, e) seteuid(e)'' and have it work. + The important thing is that you have a call that will set + the effective uid independently of the real or saved uid + and be able to set the effective uid back again when done. + There's a test program in ../test/t_setreuid.c that will + try things on your system. Setting this improves the + security, since sendmail doesn't have to read .forward + and :include: files as root. There are certain attacks + that may be unpreventable without this call. +USESETEUID Define this to 1 if you have seteuid(2) if you have a seteuid + system call that will allow root to set only the effective + user id to an arbitrary value ***AND*** you have saved user + ids. This is preferable to HASSETREUID if these conditions + are fulfilled. These are the semantics of the to-be-released + revision of Posix.1. The test program ../test/t_seteuid.c + will try this out on your system. If you define both + HASSETREUID and USESETEUID, the former is ignored. +HASLSTAT Define this if you have symbolic links (and thus the + lstat(2) system call). This improves security. Unlike + most other options, this one is on by default, so you + need to #undef it in conf.h if you don't have symbolic + links (these days everyone does). +HASSETRLIMIT Define this to 1 if you have the setrlimit(2) syscall. + You can define it to 0 to force it off. It is assumed + if you are running a BSD-like system. +HASULIMIT Define this if you have the ulimit(2) syscall (System V + style systems). HASSETRLIMIT overrides, as it is more + general. +HASWAITPID Define this if you have the waitpid(2) syscall. +HASGETDTABLESIZE + Define this if you have the getdtablesize(2) syscall. +NEEDGETOPT Define this if you need a reimplementation of getopt(3). + On some systems, getopt does very odd things if called + to scan the arguments twice. This flag will ask sendmail + to compile in a local version of getopt that works + properly. +NEEDSTRTOL Define this if your standard C library does not define + strtol(3). This will compile in a local version. +NEEDVPRINTF Define this if your standard C library does not define + vprintf(3). Note that the resulting fake implementation + is not very elegant and may not even work on some + architectures. +NEEDFSYNC Define this if your standard C library does not define + fsync(2). This will try to simulate the operation using + fcntl(2); if that is not available it does nothing, which + isn't great, but at least it compiles and runs. +HASGETUSERSHELL Define this to 1 if you have getusershell(3) in your + standard C library. If this is not defined, or is defined + to be 0, sendmail will scan the /etc/shells file (no + NIS-style support, defaults to /bin/sh and /bin/csh if + that file does not exist) to get a list of unrestricted + user shells. This is used to determine whether users + are allowed to forward their mail to a program or a file. +NEEDPUTENV Define this if your system needs am emulation of the + putenv(3) call. Define to 1 to implement it in terms + of setenv(3) or to 2 to do it in terms of primitives. +NOFTRUNCATE Define this if you don't have the ftruncate(2) syscall. + If you don't have this system call, there is an unavoidable + race condition that occurs when creating alias databases. +GIDSET_T The type of entries in a gidset passed as the second + argument to getgroups(2). Historically this has been an + int, so this is the default, but some systems (such as + IRIX) pass it as a gid_t, which is an unsigned short. + This will make a difference, so it is important to get + this right! However, it is only an issue if you have + group sets. +SLEEP_T The type returned by the system sleep() function. + Defaults to "unsigned int". Don't worry about this + if you don't have compilation problems. +ARBPTR_T The type of an arbitrary pointer -- defaults to "void *". + If you are an very old compiler you may need to define + this to be "char *". +LA_TYPE The type of load average your kernel supports. These + can be one of: + LA_ZERO (1) -- it always returns the load average as + "zero" (and does so on all architectures). + LA_INT (2) to read /dev/kmem for the symbol avenrun and + interpret as a long integer. + LA_FLOAT (3) same, but interpret the result as a floating + point number. + LA_SHORT (6) to interpret as a short integer. + LA_SUBR (4) if you have the getloadavg(3) routine in your + system library. + LA_MACH (5) to use MACH-style load averages (calls + processor_set_info()), + LA_PROCSTR (7) to read /proc/loadavg and interpret it + as a string representing a floating-point + number (Linux-style). + LA_READKSYM (8) is an implementation suitable for some + versions of SVr4 that uses the MIOC_READKSYM ioctl + call to read /dev/kmem. + LA_DGUX (9) is a special implementation for DG/UX that uses + the dg_sys_info system call. + LA_HPUX (10) is an HP-UX specific version that uses the + pstat_getdynamic system call. + LA_INT, LA_SHORT, LA_FLOAT, and LA_READKSYM have several + other parameters that they try to divine: the name of your + kernel, the name of the variable in the kernel to examine, + the number of bits of precision in a fixed point load average, + and so forth. + In desperation, use LA_ZERO. The actual code is in + conf.c -- it can be tweaked if you are brave. +FSHIFT For LA_INT, LA_SHORT, and LA_READKSYM, this is the number + of bits of load average after the binary point -- i.e., + the number of bits to shift right in order to scale the + integer to get the true integer load average. Defaults to 8. +_PATH_UNIX The path to your kernel. Needed only for LA_INT, LA_SHORT, + and LA_FLOAT. Defaults to "/unix" on System V, "/vmunix" + everywhere else. +LA_AVENRUN For LA_INT, LA_SHORT, and LA_FLOAT, the name of the kernel + variable that holds the load average. Defaults to "avenrun" + on System V, "_avenrun" everywhere else. +SFS_TYPE Encodes how your kernel can locate the amount of free + space on a disk partition. This can be set to SFS_NONE + (0) if you have no way of getting this information, + SFS_USTAT (1) if you have the ustat(2) system call, + SFS_4ARGS (2) if you have a four-argument statfs(2) + system call (and the include file is <sys/statfs.h>), + SFS_VFS (3), SFS_MOUNT (4), SFS_STATFS (5) if you have + the two-argument statfs(2) system call with includes in + <sys/vfs.h>, <sys/mount.h>, or <sys/statfs.h> respectively, + or SFS_STATVFS (6) if you have the two-argument statvfs(2) + call. The default if nothing is defined is SFS_NONE. +SFS_BAVAIL with SFS_4ARGS hou can also set SFS_BAVAIL to the field name + in the statfs structure that holds the useful information; + this defaults to f_bavail. +SPT_TYPE Encodes how your system can display what a process is doing + on a ps(1) command (SPT stands for Set Process Title). Can + be set to: + SPT_NONE (0) -- Don't try to set the process title at all. + SPT_REUSEARGV (1) -- Pad out your argv with the information; + this is the default if none specified. + SPT_BUILTIN (2) -- The system library has setproctitle. + SPT_PSTAT (3) -- Use the PSTAT_SETCMD option to pstat(2) + to set the process title; this is used by HP-UX. + SPT_PSSTRINGS (4) -- Use the magic PS_STRINGS pointer (4.4BSD). +SPT_PADCHAR Character used to pad the process title; if undefined, + the space character (0x20) is used. This is ignored if + SPT_TYPE != SPT_REUSEARGV +ERRLIST_PREDEFINED + If set, assumes that some header file defines sys_errlist. + This may be needed if you get type conflicts on this + variable -- otherwise don't worry about it. +WAITUNION The wait(2) routine takes a "union wait" argument instead + of an integer argument. This is for compatibility with + old versions of BSD. +SCANF You can set this to extend the F command to accept a + scanf string -- this gives you a primitive parser for + class definitions -- BUT it can make you vulnerable to + core dumps if the target file is poorly formed. +SYSLOG_BUFSIZE You can define this to be the size of the buffer that + syslog accepts. If it is not defined, it assumes a + 1024-byte buffer. If the buffer is very small (under + 256 bytes) the log message format changes -- each + e-mail message will log many more messages, since it + will log each piece of information as a separate line + in syslog. +BROKEN_RES_SEARCH + On Ultrix (and maybe other systems?) if you use the + res_search routine with an unknown host name, it returns + -1 but sets h_errno to 0 instead of HOST_NOT_FOUND. If + you set this, sendmail considers 0 to be the same as + HOST_NOT_FOUND. +NAMELISTMASK If defined, values returned by nlist(3) are masked + against this value before use -- a common value is + 0x7fffffff to strip off the top bit. +BSD4_4_SOCKADDR If defined, socket addresses have an sa_len field that + defines the length of this address. + + + ++-----------------------+ +| COMPILE-TIME FEATURES | ++-----------------------+ + +There are a bunch of features that you can decide to compile in, such +as selecting various database packages and special protocol support. +Several are assumed based on other compilation flags -- if you want to +"un-assume" something, you probably need to edit conf.h. Compilation +flags that add support for special features include: + +NDBM Include support for "new" DBM library for aliases and maps. + Normally defined in the Makefile. +NEWDB Include support for Berkeley "db" package (hash & btree) + for aliases and maps. Normally defined in the Makefile. +OLD_NEWDB If non-zero, the version of NEWDB you have is the old + one that does not include the "fd" call. This call was + added in version 1.5 of the Berkeley DB code. If you + use -DOLD_NEWDB=0 it forces you to use the new interface. +NIS Define this to get NIS (YP) support for aliases and maps. + Normally defined in the Makefile. +NISPLUS Define this to get NIS+ support for aliases and maps. + Normally defined in the Makefile. +HESIOD Define this to get Hesiod support for aliases and maps. + Normally defined in the Makefile. +NETINFO Define this to get NeXT NetInfo support for aliases and maps. + Normally defined in the Makefile. +USERDB Define this to 1 to include support for the User Information + Database. Implied by NEWDB or HESIOD. You can use + -DUSERDB=0 to explicitly turn it off. +IDENTPROTO Define this as 1 to get IDENT (RFC 1413) protocol support. + This is assumed unless you are running on Ultrix or + HP-UX, both of which have a problem in the UDP + implementation. You can define it to be 0 to explicitly + turn off IDENT protocol support. If defined off, the code + is actually still compiled in, but it defaults off; you + can turn it on by setting the IDENT timeout to 30s in the + configuration file. +IP_SRCROUTE Define this to 1 to get IP source routing information + displayed in the Received: header. This is assumed on + most systems, but some (e.g., Ultrix) apparently have a + broken version of getsockopt that doesn't properly + support the IP_OPTIONS call. You probably want this if + your OS can cope with it. Symptoms of failure will be that + it won't compile properly (that is, no support for fetching + IP_OPTIONs), or it compiles but source-routed TCP connections + either refuse to open or open and hang for no apparent reason. + Ultrix and AIX are known to fail this way. +LOG Set this to get syslog(3) support. Defined by default + in conf.h. You want this if at all possible. +NETINET Set this to get TCP/IP support. Defined by default + in conf.h. You probably want this. +NETISO Define this to get ISO networking support. +NETUNIX Define this to get Unix domain networking support. Defined + by default. A few bizarre systems (SCO, ISC, Altos) don't + support this networking domain. +SMTP Define this to get the SMTP code. Implied by NETINET + or NETISO. +NAMED_BIND If non-zero, include DNS (name daemon) support, including + MX support. The specs say you must use this if you run + SMTP. You don't have to be running a name server daemon + on your machine to need this -- any use of the DNS resolver, + including remote access to another machine, requires this + option. Defined by default in conf.h. Define it to zero + ONLY on machines that do not use DNS in any way. +QUEUE Define this to get queueing code. Implied by NETINET + or NETISO; required by SMTP. This gives you other good + stuff -- it should be on. +DAEMON Define this to get general network support. Implied by + NETINET or NETISO. Defined by default in conf.h. You + almost certainly want it on. +MATCHGECOS Permit fuzzy matching of user names against the full + name (GECOS) field in the /etc/passwd file. This should + probably be on, since you can disable it from the config + file if you want to. Defined by default in conf.h. +MIME8TO7 If non-zero, include 8 to 7 bit MIME conversions. This + also controls advertisement of 8BITMIME in the ESMTP + startup dialogue. +MIME7TO8 If non-zero, include 7 to 8 bit MIME conversions. Not yet + implemented. +HES_GETMAILHOST Define this to 1 if you are using Hesiod with the + hes_getmailhost() routine. This is included with the MIT + Hesiod distribution, but not with the DEC Hesiod distribution. +XDEBUG Do additional internal checking. These don't cost too + much; you might as well leave this on. + + ++---------------------+ +| DNS/RESOLVER ISSUES | ++---------------------+ + +Many systems have old versions of the resolver library. At a minimum, +you should be running BIND 4.8.3; older versions may compile, but they +have known bugs that should give you pause. + +Common problems in old versions include "undefined" errors for +dn_skipname. + +Some people have had a problem with BIND 4.9; it uses some routines +that it expects to be externally defined such as strerror(). It may +help to link with "-l44bsd" to solve this problem. + +!PLEASE! be sure to link with the same version of the resolver as +the header files you used -- some people have used the 4.9 headers +and linked with BIND 4.8 or vice versa, and it doesn't work. +Unfortunately, it doesn't fail in an obvious way -- things just +subtly don't work. + +WILDCARD MX RECORDS ARE A BAD IDEA! The only situation in which they +work reliably is if you have two versions of DNS, one in the real world +which has a wildcard pointing to your firewall, and a completely +different version of the database internally that does not include +wildcard MX records that match your domain.

According to Sun + bug number 1077939: + + If an application does a getsockopt() on a SOCK_STREAM (TCP) socket + after the other side of the connection has sent a TCP RESET for + the stream, the kernel gets a Bus Trap in the tcp_ctloutput() or + ip_ctloutput() routine. + + This is fixed in patch 101790-01 (SunOS 4.1.3_U1: TCP socket and + reset problems). + +Solaris 2.x (SunOS 5.x) + To compile for Solaris, be sure you use -DSOLARIS. + + To the best of my knowledge, Solaris does not have the + gethostbyname problem described above. However, it does + have another one: + + From a correspondent: + + For solaris 2.2, I have + + hosts: files dns + + in /etc/nsswitch.conf and /etc/hosts has to have the fully + qualified host name. I think "files" has to be before "dns" + in /etc/nsswitch.conf during bootup. + + From another correspondent: + + When running sendmail under Solaris, the gethostbyname() + hack in conf.c which should perform proper canonicalization + of host names could fail. Result: the host name is not + canonicalized despite the hack, and you'll have to define $j + and $m in sendmail.cf somewhere. + + The reason could be that /etc/nsswitch.conf is improperly + configured (at least from sendmail's point of view). For + example, the line + + hosts: files nisplus dns + + will make gethostbyname() look in /etc/hosts first, then ask + nisplus, then dns. However, if /etc/hosts does not contain + the full canonicalized hostname, then no amount of + gethostbyname()s will work. + + Solution (or rather, a workaround): Ask nisplus first, then + dns, then local files: + + hosts: nisplus dns [NOTFOUND=return] files + + The Solaris "syslog" function is apparently limited to something + about 90 characters because of a kernel limitation. If you have + source code, you can probably up this number. You can get patches + that fix this problem: the patch ids are: + + Solaris 2.1 100834 + Solaris 2.2 100999 + Solaris 2.3 101318 + + Be sure you have the appropriate patch installed or you won't + see system logging. + +Solaris 2.4 (SunOS 5.4) + If you include /usr/lib at the end of your LD_LIBRARY_PATH you run + the risk of getting the wrong libraries under some circumstances. + This is because of a new feature in Solaris 2.4, described by + Rod.Evans@Eng.Sun.COM: + + >> Prior to SunOS 5.4, any LD_LIBRARY_PATH setting was ignored by the + >> runtime linker if the application was setxid (secure), thus your + >> applications search path would be: + >> + >> /usr/local/lib LD_LIBRARY_PATH component - IGNORED + >> /usr/lib LD_LIBRARY_PATH component - IGNORED + >> /usr/local/lib RPATH - honored + >> /usr/lib RPATH - honored + >> + >> the effect is that path 3 would be the first used, and this would + >> satisfy your resolv.so lookup. + >> + >> In SunOS 5.4 we made the LD_LIBRARY_PATH a little more flexible. + >> People who developed setxid applications wanted to be able to alter + >> the library search path to some degree to allow for their own + >> testing and debugging mechanisms.

This change was made as part of 1155380 - after a + >> *huge* amount of discussion regarding the security aspect of things. + >> + >> So, in SunOS 5.4 your applications search path would be: + >> + >> /usr/local/lib from LD_LIBRARY_PATH - IGNORED (untrustworthy) + >> /usr/lib from LD_LIBRARY_PATH - honored (trustworthy) + >> /usr/local/lib from RPATH - honored + >> /usr/lib from RPATH - honored + >> + >> here, path 2 would be the first used. + +Ultrix + By default, the IDENT protocol is turned off on Ultrix. If you + are running Ultrix 4.4 or later, or if you have included patch + CXO-8919 for Ultrix 4.2 or 4.3 to fix the TCP problem, you can turn + IDENT on in the configuration file by setting the "ident" timeout + to 30 seconds. + +OSF/1 + If you are compiling on OSF/1 (DEC Alpha), you must use + -L/usr/shlib (otherwise it core dumps on startup). You may also + need -mld to get the nlist() function, although some versions + apparently don't need this. + + Also, the enclosed makefile removed /usr/sbin/smtpd; if you need + it, just create the link to the sendmail binary. + +IRIX + The header files on SGI IRIX are completely prototyped, and as + a result you can sometimes get some warning messages during + compilation. These can be ignored. There are two errors in + deliver only if you are using gcc, both of the form ``warning: + passing arg N of `execve' from incompatible pointer type''. + Also, if you compile with -DNIS, you will get a complaint + about a declaration of struct dom_binding in a prototype + when compiling map.c; this is not important because the + function being prototyped is not used in that file. + + In order to compile sendmail you will have had to install + the developers' option in order to get the necessary include + files. + +NeXT or NEXTSTEP + NEXTSTEP 3.3 and earlier ship with the old DBM library. You will + need to acquire the new Berkeley DB from ftp.cs.berkeley.edu. + Install it in /usr/local/{lib,include}. + + If you are compiling on NEXTSTEP, you will have to create an + empty file "unistd.h" and create a file "dirent.h" containing: + + #include <sys/dir.h> + #define dirent direct + + (The Makefile.NeXT should try to do both of these for you.) + + Apparently, there is a bug in getservbyname on Nextstep 3.0 + that causes it to fail under some circumstances with the + message "SYSERR: service "smtp" unknown" logged. You should + be able to work around this by including the line: + + OOPort=25 + + in your .cf file. + + You may have to use -DNeXT. + +BSDI (BSD/386) 1.0, NetBSD 0.9, FreeBSD 1.0 + The "m4" from BSDI won't handle the config files properly. + I haven't had a chance to test this myself. + + The M4 shipped in FreeBSD and NetBSD 0.9 don't handle the config + files properly. One must use either GNU m4 1.1 or the PD-M4 + recently posted in comp.os.386bsd.bugs (and maybe others). + NetBSD-current includes the PD-M4 (as stated in the NetBSD file + CHANGES). + + FreeBSD 1.0 RELEASE has uname(2) now. Use -DUSEUNAME in order to + use it (look into Makefile.FreeBSD). NetBSD-current may have + it too but it has not been verified. + + You cannot port the latest version of the Berkeley db library + and use it with sendmail without recompiling the world. This + is because C library routines use the older version which have + incompatible header files -- the result is that it can't read + other system files, such as /etc/passwd, unless you use the + new db format throughout your system. You should normally just + use the version of db supplied in your release. You may need + to use -DOLD_NEWDB=1 to make this work -- this turns off some + new interface calls (for file locking) that are not in older + versions of db. You'll get compile errors if you need this + flag and don't have it set. + +4.3BSD + If you are running a "virgin" version of 4.3BSD, you'll have + a very old resolver and be missing some header files. The + header files are simple -- create empty versions and everything + will work fine. For the resolver you should really port a new + version (4.8.3 or later) of the resolver; 4.9 is available on + gatekeeper.DEC.COM in pub/BSD/bind/4.9. If you are really + determined to continue to use your old, buggy version (or as + a shortcut to get sendmail working -- I'm sure you have the + best intentions to port a modern version of BIND), you can + copy ../contrib/oldbind.compat.c into src and add + oldbind.compat.o to OBJADD in the Makefile. + +A/UX + Date: Tue, 12 Oct 1993 18:28:28 -0400 (EDT) + From: "Eric C. Hagberg" <hagberg@med.cornell.edu> + Subject: Fix for A/UX ndbm + + I guess this isn't really a sendmail bug, however, it is something + that A/UX users should be aware of when compiling sendmail 8.6. + + Apparently, the calls that sendmail is using to the ndbm routines + in A/UX 3.0.x contain calls to "broken" routines, in that the + aliases database will break when it gets "just a little big" + (sorry I don't have exact numbers here, but it broke somewhere + around 20-25 aliases for me.), making all aliases non-functional + after exceeding this point. + + What I did was to get the gnu-dbm-1.6 package, compile it, and + then re-compile sendmail with "-lgdbm", "-DNDBM", and using the + ndbm.h header file that comes with the gnu-package. This makes + things behave properly. + + I suppose porting the New Berkeley db package is another route, + however, I made a quick attempt at it, and found it difficult + (not easy at least); the gnu-dbm package "configured" and + compiled easily. + +SCO Unix + From: Thomas Essebier <tom@stallion.oz.au> + Organisation: Stallion Technologies Pty Ltd. + + It will probably help those who are trying to configure sendmail 8.6.9 + to know that if they are on SCO, they had better set + OI-dnsrch + or they will core dump as soon as they try to use the resolver. + ie. although SCO has _res.dnsrch defined, and is kinda BIND 4.8.3, it + does not inititialise it, nor does it understand 'search' in + /etc/named.boot. + - sigh - + +DG/UX + Doug Anderson <dlander@afterlife.ncsc.mil> has successfully run + V8 on the DG/UX 5.4.2 and 5.4R3.x platforms under heavy usage. + Originally, the DG /bin/mail program wasn't compatible with + the V8 sendmail, since the DG /bin/mail requires the environment + variable "_FORCE_MAIL_LOCAL_=yes" be set.

This is supposedly fixed in + later versions of libc (>= 4.6.29?), and later versions of + sendmail (> 8.6.10) try to work around the problem. + + Some older versions (< 4.6.20?) of the libc/include files conflict + with sendmail's version of cdefs.h. Deleting sendmail's version + on those systems should be non-harmful, and new versions don't care. + + Sendmail assumes that libc has snprintf, which has been true since + libc 4.7.0.

It is too old, and gives you problems with + clock.c, because sigset_t won't get defined in <sys/signal.h>. + This is due to a problematic protection rule in there, and is + fixed with gcc 2.4.5. + + 2) If you don't use the new Berkeley DB (-DNEWDB), then you need + to add "-lc -lucb" to the libraries to link with. This is because + the -ldbm distributed by Dell needs the bcopy, bcmp and bzero + functions. It is important that you specify both libraries in + the given order to be sure you only get the BSTRING functions + from the UCB library (and not the signal routines etc.). + + 3) Don't leave out "-lelf" even if compiling with "-lc -lucb". + The UCB library also has another copy of the nlist routines, + but we do want the ones from "-lelf". + + If anyone needs a compiled gcc 2.4.5 and/or a ported DB library, they + can use anonymous ftp to fetch them from lut.fi in the /kim directory. + They are copies of what I use on grendel.lut.fi, and offering them + does not imply that I would also support them. I have sent the DB + port for SVR4 back to Keith Bostic for inclusion in the official + distribution, but I haven't heard anything from him as of today. + + - gcc-2.4.5-svr4.tar.gz (gcc 2.4.5 and the corresponding libg++) + - db-1.72.tar.gz (with source, objects and a installed copy) + + Cheers + + Kim + -- + * Kimmo.Suominen@lut.fi * SysVr4 enthusiast at GRENDEL.LUT.FI * + * KIM@FINFILES.BITNET * Postmaster and Hostmaster at LUT.FI * + * + 358 200 865 718 * Unix area moderator at NIC.FUNET.FI * + +ConvexOS 10.1 and below + In order to use the name server, you must create the file + /etc/use_nameserver. If this file does not exist, the call + to res_init() will fail and you will have absolutely no + access to DNS, including MX records. + +Amdahl UTS 2.1.5 + In order to get UTS to work, you will have to port BIND 4.9. + The vendor's BIND is reported to be ``totally inadequate.'' + See sendmail/contrib/AmdahlUTS.patch for the patches necessary + to get BIND 4.9 compiled for UTS. + +UnixWare 2.0 + According to Alexander Kolbasov <sasha@unitech.gamma.ru>, + the m4 on UnixWare 2.0 (still in Beta) will core dump on the + config files. GNU m4 and the m4 from UnixWare 1.x both work. + +UNICOS 8.0.3.4 + Some people have reported that the -O flag on UNICOS can cause + problems. You may want to turn this off if you have problems + running sendmail. Reported by Jerry G. DeLapp <jgd@acl.lanl.gov>. + +Non-DNS based sites + This version of sendmail always tries to connect to the Domain + Name System (DNS) to resolve names, regardless of the setting + of the `I' option. On most systems that are not running DNS, + this will fail quickly and sendmail will continue, but on some + systems it has a long timeout. If you have this problem, you + will have to recompile without NAMED_BIND. Some people have + claimed that they have successfully used "OI+USEVC" to force + sendmail to use a virtual circuit -- this will always time out + quickly, but also tells sendmail that a failed connection + should requeue the message (probably not what you intended). + A future release of sendmail will correct this problem. + +Both NEWDB and NDBM + If you use both -DNDBM and -DNEWDB, you must delete the module + ndbm.o from libdb.a and delete the file "ndbm.h" from the files + that get installed (that is, use the OLD ndbm.h, not the new + ndbm.h). This compatibility module maps ndbm calls into DB + calls, and breaks things rather badly. + +GNU getopt + I'm told that GNU getopt has a problem in that it gets confused + by the double call. Use the version in conf.c instead. + +BIND 4.9.2 and Ultrix + If you are running on Ultrix, be sure you read conf/Info.Ultrix + in the BIND distribution very carefully -- there is information + in there that you need to know in order to avoid errors of the + form: + + /lib/libc.a(gethostent.o): sethostent: multiply defined + /lib/libc.a(gethostent.o): endhostent: multiply defined + /lib/libc.a(gethostent.o): gethostbyname: multiply defined + /lib/libc.a(gethostent.o): gethostbyaddr: multiply defined + + during the link stage. + +strtoul + Some compilers (notably gcc) claim to be ANSI C but do not + include the ANSI-required routine "strtoul". If your compiler + has this problem, you will get an error in srvrsmtp.c on the + code: + + # ifdef defined(__STDC__) && !defined(BROKEN_ANSI_LIBRARY) + e->e_msgsize = strtoul(vp, (char **) NULL, 10); + # else + e->e_msgsize = strtol(vp, (char **) NULL, 10); + # endif + + You can use -DBROKEN_ANSI_LIBRARY to get around this problem. + +Listproc 6.0c + Date: 23 Sep 1995 23:56:07 GMT + Message-ID: <95925101334.~INN-AUMa00187.comp-news@dl.ac.uk> + From: alansz@mellers1.psych.berkeley.edu (Alan Schwartz) + Subject: Listproc 6.0c + Sendmail 8.7 [Helpful hint] + + Just upgraded to sendmail 8.7, and discovered that listproc 6.0c + breaks, because it, by default, sends a blank "HELO" rather than + a "HELO hostname" when using the 'system' or 'telnet' mailmethod. + + The fix is to include -DZMAILER in the compilation, which will + cause it to use "HELO hostname" (which Z-mail apparently requires + as well. :) + + + ++--------------+ +| MANUAL PAGES | ++--------------+ + +The manual pages have been written against the -mandoc macros +instead of the -man macros. The latest version of groff has them +included. You can also get a copy from FTP.UU.NET in directory +/systems/unix/bsd-sources/share/tmac. + + ++-----------------+ +| DEBUGGING HOOKS | ++-----------------+ + +As of 8.6.5, sendmail daemons will catch a SIGUSR1 signal and log +some debugging output (logged at LOG_DEBUG severity). The +information dumped is: + + * The value of the $j macro. + * A warning if $j is not in the set $=w. + * A list of the open file descriptors. + * The contents of the connection cache. + * If ruleset 89 is defined, it is evaluated and the results printed. + +This allows you to get information regarding the runtime state of the +daemon on the fly. This should not be done too frequently, since +the process of rewriting may lose memory which will not be recovered. +Also, ruleset 89 may call non-reentrant routines, so there is a small +non-zero probability that this will cause other problems. It is +really only for debugging serious problems. + +A typical formulation of ruleset 89 would be: + + R$* $@ $>0 some test address + + ++-----------------------------+ +| DESCRIPTION OF SOURCE FILES | ++-----------------------------+ + +The following list describes the files in this directory: + +Makefile The makefile used here; this version only works with + the new Berkeley make. +Makefile.dist A trimmed down version of the makefile that works with + the old make. +READ_ME This file. +TRACEFLAGS My own personal list of the trace flags -- not guaranteed + to be particularly up to date. +alias.c Does name aliasing in all forms. +arpadate.c A subroutine which creates ARPANET standard dates. +clock.c Routines to implement real-time oriented functions + in sendmail -- e.g., timeouts. +collect.c The routine that actually reads the mail into a temp + file. It also does a certain amount of parsing of + the header, etc. +conf.c The configuration file. This contains information + that is presumed to be quite static and non- + controversial, or code compiled in for efficiency + reasons. Most of the configuration is in sendmail.cf. +conf.h Configuration that must be known everywhere. +convtime.c A routine to sanely process times. +daemon.c Routines to implement daemon mode. This version is + specifically for Berkeley 4.1 IPC. +deliver.c Routines to deliver mail. +domain.c Routines that interface with DNS (the Domain Name + System). +err.c Routines to print error messages. +envelope.c Routines to manipulate the envelope structure. +headers.c Routines to process message headers. +macro.c The macro expander. This is used internally to + insert information from the configuration file. +main.c The main routine to sendmail. This file also + contains some miscellaneous routines. +map.c Support for database maps. +mci.c Routines that handle mail connection information caching. +parseaddr.c The routines which do address parsing. +queue.c Routines to implement message queueing. +readcf.c The routine that reads the configuration file and + translates it to internal form. +recipient.c Routines that manipulate the recipient list. +savemail.c Routines which save the letter on processing errors. +sendmail.h Main header file for sendmail. +srvrsmtp.c Routines to implement server SMTP. +stab.c Routines to manage the symbol table. +stats.c Routines to collect and post the statistics. +sysexits.c List of error messages associated with error codes + in sysexits.h. +trace.c The trace package. These routines allow setting and + testing of trace flags with a high granularity. +udb.c The user database interface module. +usersmtp.c Routines to implement user SMTP. +util.c Some general purpose routines used by sendmail. +version.c The version number and information about this + version of sendmail. Theoretically, this gets + modified on every change. + +Eric Allman + +(Version 8.112, last update 11/18/95 08:44:31) diff --git a/usr.sbin/sendmail/src/TRACEFLAGS b/usr.sbin/sendmail/src/TRACEFLAGS new file mode 100644 index 000000000000..f2499aac0913 --- /dev/null +++ b/usr.sbin/sendmail/src/TRACEFLAGS @@ -0,0 +1,71 @@ +0, 1 main.c main skip background fork +0, 4 main.c main canonical name, UUCP node name, a.k.a.s +0, 15 main.c main print configuration +0, 44 util.c printav print address of each string +1 main.c main print from person +2 main.c finis +3 conf.c getla, shouldqueue +4 conf.c enoughspace +5 clock.c setevent, clrevent, tick +6 savemail.c savemail, returntosender +7 queue.c queuename +8 domain.c getmxrr, getcanonname +9 daemon.c getauthinfo IDENT protocol +9 daemon.c maphostname +10 deliver.c deliver +11 deliver.c openmailer, mailfile +12 parseaddr.c remotename +13 deliver.c sendall, sendenvelope +14 headers.c commaize +15 daemon.c getrequests +16 daemon.c makeconnection +17 deliver.c hostsignature +17 domain.c mxrand +18 usersmtp.c reply, smtpmessage, smtpinit, smtpmailfrom +19 srvrsmtp.c smtp +20 parseaddr.c parseaddr +21 parseaddr.c rewrite +22 parseaddr.c prescan +24 parseaddr.c buildaddr, allocaddr +25 recipient.c sendtolist +26 recipient.c recipient +27 alias.c alias +27 alias.c readaliases +27 alias.c forward +27 recipient.c include +28 udb.c udbexpand, udbsender +29 parseaddr.c maplocaluser +29 recipient.c recipient (local users), finduser +30 collect.c collect +30 collect.c eatfrom +31 headers.c chompheader +32 headers.c eatheader +33 headers.c crackaddr +34 headers.c putheader +35 macro.c expand, define +36 stab.c stab +37 readcf.c (many) +38 map.c initmaps +39 map.c map_rewrite +40 queue.c queueup, orderq, dowork +41 queue.c orderq +42 mci.c mci_get +43 mime.c mime8to7 +44 recipient.c writeable +44 util.c safefile +45 envelope.c setsender +46 envelope.c openxscript +49 conf.c checkcompat +50 envelope.c dropenvelope +51 queue.c unlockqueue +52 main.c disconnect +53 util.c xfclose +54 err.c putoutmsg +55 conf.c lockfile +59 Extended Load Average implementation from Christophe Wolfhugel +60 map.c +61 conf.c sm_gethostbyname +80 content length +81 sun remote mode +91 mci.c syslogging of MCI cache information +99 main.c avoid backgrounding (no printed output) diff --git a/usr.sbin/sendmail/src/alias.c b/usr.sbin/sendmail/src/alias.c new file mode 100644 index 000000000000..2bc4487d4a36 --- /dev/null +++ b/usr.sbin/sendmail/src/alias.c @@ -0,0 +1,835 @@ +/* + * Copyright (c) 1983, 1995 Eric P.
