It is necessary to first build libmilter.a, which can be done by -issuing the './Build' command in SRCDIR/libmilter . - -NOTE: If you intend to use filters in sendmail, you must compile sendmail -with -DMILTER defined.

Libmilter -does not need root access to communicate with sendmail. It is a -good security practice to run a program only with root privileges -if really necessary. A milter should probably check first whether -it runs as root and refuse to start in that case. There is a -compile time option _FFR_MILTER_ROOT_UNSAFE which keeps libmilter -from unlinking a socket when running as root. It is recommended -to turn on this option: - - APPENDDEF(`conf_libmilter_ENVDEF', `-D_FFR_MILTER_ROOT_UNSAFE ') - - -+-------------------+ -| BUILDING A FILTER | -+-------------------+ - -The following command presumes that the sample code from the end of this -README is saved to a file named 'sample.c' and built in the local platform- -specific build subdirectory (SRCDIR/obj.*/libmilter). - - cc -I../../include -o sample sample.c libmilter.a ../libsm/libsm.a -pthread - -It is recommended that you build your filters in a location outside of -the sendmail source tree. Modify the compiler include references (-I) -and the library locations accordingly. Also, some operating systems may -require additional libraries. For example, SunOS 5.X requires '-lresolv --lsocket -lnsl'. Depending on your operating system you may need a library -instead of the option -pthread, e.g., -lpthread. - -Filters must be thread-safe! Many operating systems now provide support for -POSIX threads in the standard C libraries. The compiler flag to link with -threading support differs according to the compiler and linker used. Check -the Makefile in your appropriate obj.*/libmilter build subdirectory if you -are unsure of the local flag used. - -Note that since filters use threads, it may be necessary to alter per -process limits in your filter. For example, you might look at using -setrlimit() to increase the number of open file descriptors if your filter -is going to be busy. - - -+----------------------------------------+ -| SPECIFYING FILTERS IN SENDMAIL CONFIGS | -+----------------------------------------+ - -Filters are specified with a key letter ``X'' (for ``eXternal''). - -For example: - - Xfilter1, S=local:/var/run/f1.sock, F=R - Xfilter2, S=inet6:999@localhost, F=T, T=C:10m;S:1s;R:1s;E:5m - Xfilter3, S=inet:3333@localhost - -specifies three filters. Filters can be specified in your .mc file using -the following: - - INPUT_MAIL_FILTER(`filter1', `S=local:/var/run/f1.sock, F=R') - INPUT_MAIL_FILTER(`filter2', `S=inet6:999@localhost, F=T, T=C:10m;S:1s;R:1s;E:5m') - INPUT_MAIL_FILTER(`filter3', `S=inet:3333@localhost') - -The first attaches to a Unix-domain socket in the /var/run directory; the -second uses an IPv6 socket on port 999 of localhost, and the third uses an -IPv4 socket on port 3333 of localhost. The current flags (F=) are: - - R Reject connection if filter unavailable - T Temporary fail connection if filter unavailable - -If neither F=R nor F=T is specified, the message is passed through sendmail -in case of filter errors as if the failing filters were not present. - -Finally, you can override the default timeouts used by sendmail when -talking to the filters using the T= equate. There are four fields inside -of the T= equate: - -Letter Meaning - C Timeout for connecting to a filter (if 0, use system timeout) - S Timeout for sending information from the MTA to a filter - R Timeout for reading reply from the filter - E Overall timeout between sending end-of-message to filter - and waiting for the final acknowledgment - -Note the separator between each is a ';' as a ',' already separates equates -and therefore can't separate timeouts. The default values (if not set in -the config) are: - -T=C:5m;S:10s;R:10s;E:5m - -where 's' is seconds and 'm' is minutes. - -Which filters are invoked and their sequencing is handled by the -InputMailFilters option. Note: if InputMailFilters is not defined no filters -will be used. - - O InputMailFilters=filter1, filter2, filter3 - -This is is set automatically according to the order of the -INPUT_MAIL_FILTER commands in your .mc file. Alternatively, you can -reset its value by setting confINPUT_MAIL_FILTERS in your .mc file. -This options causes the three filters to be called in the same order -they were specified. It allows for possible future filtering on output -(although this is not intended for this release). - -Also note that a filter can be defined without adding it to the input -filter list by using MAIL_FILTER() instead of INPUT_MAIL_FILTER() in your -.mc file. - -To test sendmail with the sample filter, the following might be added (in -the appropriate locations) to your .mc file: - - INPUT_MAIL_FILTER(`sample', `S=local:/var/run/f1.sock') - - -+------------------+ -| TESTING A FILTER | -+------------------+ - -Once you have compiled a filter, modified your .mc file and restarted -the sendmail process, you will want to test that the filter performs as -intended. - -The sample filter takes one argument -p, which indicates the local port -on which to create a listening socket for the filter. Maintaining -consistency with the suggested options for sendmail.cf, this would be the -UNIX domain socket located in /var/run/f1.sock. - - % ./sample -p local:/var/run/f1.sock - -If the sample filter returns immediately to a command line, there was either -an error with your command or a problem creating the specified socket. -Further logging can be captured through the syslogd daemon. Using the -'netstat -a' command can ensure that your filter process is listening on -the appropriate local socket. - -Email messages must be injected via SMTP to be filtered. There are two -simple means of doing this; either using the 'sendmail -bs' command, or -by telnetting to port 25 of the machine configured for milter. Once -connected via one of these options, the session can be continued through -the use of standard SMTP commands. - -% sendmail -bs -220 test.sendmail.com ESMTP Sendmail 8.11.0/8.11.0; Tue, 10 Nov 1970 13:05:23 -0500 (EST) -HELO localhost -250 test.sendmail.com Hello testy@localhost, pleased to meet you -MAIL From:<testy> -250 2.1.0 <testy>...

Filters can process messages' -connection (IP) information, envelope protocol elements, message -headers, and/or message body contents, and modify a message's -recipients, headers, and body. The MTA configuration file specifies -which filters are to be applied, and in what order, allowing an -administrator to combine multiple independently-developed filters. - -<p> -We expect to see both vendor-supplied, configurable mail filtering -applications and a multiplicity of script-like filters designed by and -for MTA administrators. A certain degree of coding sophistication and -domain knowledge on the part of the filter provider is assumed. This -allows filters to exercise fine-grained control at the SMTP level. -However, as will be seen in the example, many filtering applications -can be written with relatively little protocol knowledge. - -<p> -Given these expectations, the API is designed to achieve the following -goals: - -<OL> - <LI>Safety/security. - Filter processes should not need to run as root - (of course, they can if required, but that is a local issue); - this will simplify coding - and limit the impact of security flaws in the filter program. -<p> - <LI>Reliability. - Coding failures in a Milter process that cause that process - to hang or core-dump - should not stop mail delivery. - Faced with such a failure, - sendmail should use a default mechanism, - either behaving as if the filter were not present - or as if a required resource were unavailable. - The latter failure mode will generally have sendmail return - a 4xx SMTP code (although in later phases of the SMTP protocol - it may cause the mail to be queued for later processing). -<p> - <LI>Simplicity. - The API should make implementation of a new filter - no more difficult than absolutely necessary. - Subgoals include: - <UL> - <LI>Encourage good thread practice - by defining thread-clean interfaces including local data hooks. - <LI>Provide all interfaces required - while avoiding unnecessary pedanticism. - </UL> -<p> - <LI>Performance. - Simple filters should not seriously impact overall MTA performance. -</OL> - -<h2>Implementing Filtering Policies</h2> - -Milter is designed to allow a server administrator to combine -third-party filters to implement a desired mail filtering policy. For -example, if a site wished to scan incoming mail for viruses on several -platforms, eliminate unsolicited commercial email, and append a mandated -footer to selected incoming messages, the administrator could configure -the MTA to filter messages first through a server based anti-virus -engine, then via a large-scale spam-catching service, and finally -append the desired footer if the message still met requisite criteria. -Any of these filters could be added or changed independently. - -<p> -Thus the site administrator, not the filter writer, controls the -overall mail filtering environment. In particular, he/she must decide -which filters are run, in what order they are run, and how they -communicate with the MTA. These parameters, as well as the -actions to be taken if a filter becomes unavailable, are selectable -during MTA configuration. <a href="installation.html">Further -details</a> are available later in this document. - -<h2>MTA - Filter communication</h2> - -Filters run as separate processes, outside of the sendmail address -space. The benefits of this are threefold: - -<OL> - <LI>The filter need not run with "root" permissions, thereby - avoiding a large family of potential security problems.</LI> - - <LI>Failures in a particular filter will not affect the MTA or - other filters.</LI> - - <LI>The filter can potentially have higher performance because of - the parallelism inherent in multiple processes.</LI> -</OL> - -<p> -Each filter may communicate with multiple MTAs at the same time over -local or remote connections, using multiple threads of execution. <a -href="#figure-1">Figure 1</a> illustrates a possible network of -communication channels between a site's filters, its MTAs, and other -MTAs on the network: -</p> -<div align="center"> -<a name="figure-1"><img src="figure1.jpg" ALT=""></A><br> -<b>Figure 1: A set of MTA's interacting with a set of filters.</b> -</div> -<p> -The Milter library (libmilter) implements the communication protocol. -It accepts connections from various MTAs, passes the relevant data to -the filter through callbacks, then makes appropriate responses based -on return codes.

This -specification may change based on feedback from reviewers, and does -not bind Sendmail to offer this functionality in any release. ---> - -<h2>Introduction</h2> - -<P> -Sendmail's Content Management API (milter) provides third-party -programs to access mail messages as they are being processed by the -Mail Transfer Agent (MTA), allowing them to examine and modify message -content and meta-information. Filtering policies implemented by -Milter-conformant filters may then be centrally configured and -composed in an end-user's MTA configuration file. - -<p> -Possible uses for filters include spam rejection, virus -filtering, and content control.
