Chapter 5. Companion Programs
The sendmail distribution comes complete with
several companion programs that can help you use
sendmail.
What’s New with V8.13
Beginning with V8.13, sendmail offers expanded
output for one program and new command-line switches for a couple of
others:
A new
mailstatsdisplay (Section 5.1.1[V8.13]) includes a count of quarantined messages.A new
makemap-Dcommand-line switch (Section 5.1.2[V8.13]) allows you to define an alternative to#as a comment character.A new
vacation-jcommand-line switch (Section 5.1.3 [V8.13]) allowsvacationto respond to messages, even if a user’s name does not appear in aTo: orCc: header.A new
vacation-Rcommand-line switch (Section 5.1.4 [V8.13]) allows you to redefine the envelope-sender address from<>to one of your own choice.
A New mailstats Display
As of V8.13, sendmail can
quarantine messages based on the sender
address so that they may be reviewed before being sent (Section 11.1.2
[V8.13]). The
sendmail program keeps track of the number of
messages quarantined by updating the information in
the
statistics file
(24.9.106[3ed]), while the
mailstats program
(5.4[3ed]) summarizes that information.
Prior to V8.13, the output produced by mailstats
ended with the column that displayed the number of discarded messages
(the msgsdis column). Beginning with V8.13, a new
rightmost column has been added (called msgsqur)
that shows the number of messages that have been quarantined:
