+.Sh NAME
+.Nm mail.local
+.Nd store mail in a mailbox
+.Sh SYNOPSIS
+.Nm mail.local
+.Op Fl f Ar from
+.Ar user ...
+.Sh DESCRIPTION
+.Nm Mail.local
+reads the standard input up to an end-of-file and appends it to each
+.Ar user's
+.Pa mail
+file.
+The
+.Ar user
+must be a valid user name.
+.Pp
+The options are as follows:
+.Bl -tag -width xxxfrom
+.It Fl f Ar from
+Specify the sender's name.
+.El
+.Pp
+Individual mail messages in the mailbox are delimited by an empty
+line followed by a line beginning with the string ``From ''.
+A line containing the string ``From '', the sender's name and a time stamp
+is prepended to each delivered mail message.
+A blank line is appended to each message.
+A greater-than character (``>'') is prepended to any line in the message
+which could be mistaken for a ``From '' delimiter line.
+.Pp
+The mail files are exclusively locked with 
+.Xr flock 2
+while mail is appended.
+.Pp
+If the ``biff'' service is returned by
+.Xr getservbyname 3 ,
+the biff server is notified of delivered mail.
+.Pp
+The
+.Nm mail.local
+utility exits 0 on success, and >0 if an error occurs.
+.Sh ENVIRONMENT
+.Bl -tag -width indent
+.It Ev TZ
+Used to set the appropriate time zone on the timestamp.
+.El
+.Sh FILES
+.Bl -tag -width /tmp/local.XXXXXX -compact
+.It Pa /tmp/local.XXXXXX
+temporary files
+.It Pa /var/mail/user
+user's mailbox directory
+.El
+.Sh SEE ALSO
+.Xr mail 1 ,
+.Xr xsend 1 ,
+.Xr flock 2 ,
+.Xr getservbyname 3 ,
+.Xr comsat 8 ,
+.Xr sendmail 8
+.Sh HISTORY
+A superset of
+.Nm mail.local
+(handling mailbox reading as well as mail delivery)
+appeared in
+.At v7 .
+as the program
+.Nm mail .
