I've uploaded Mail-Procmail-0.02.tar.gz (module Mail::Procmail) to PAUSE.
Introduction
------------
procmail is one of the most powerfull tools in use on Unix systems to
filter incoming email. It is, however, rather complicated and
configuring it can be a pain.
Mail::Procmail.pm is a perl 5.6 module that provides procmail-like
tools that you can use to write your own mail filtering program.
For example, a simple filter that copies incoming mail regarding a
specific subject to a separate mailbox, while also sending it to a
friend:
#!/usr/bin/perl -w
use strict;
use Mail::Procmail;
pm_init(logfile=>'stderr', loglevel=>3);
if ( pm_gethdr("subject") =~ /interesting topic/i ) {
pm_resend("[EMAIL PROTECTED]", continue => 1);
pm_deliver($ENV{HOME}."/Mail/interesting");
}
# Default delivery.
pm_deliver("/var/spool/mail/".getpwuid($>));
As can be deduced from the pm_init call, logging will be done to
standard error. If a suitable message comes along, the following
information will be logged:
2000/08/08 21:23:55 Mail from John Doe <[EMAIL PROTECTED]>
2000/08/08 21:23:55 To: [EMAIL PROTECTED]
2000/08/08 21:23:55 Subject: This is an interesting topic
2000/08/08 21:23:55 resend[6]: [EMAIL PROTECTED]
2000/08/08 21:23:55 deliver[7]: /home/jv/Mail/interesting
The number between [ ] shows the line number in your program that
caused the delivery. This makes it easy to find out what rule
triggered the delivery.
If the message did not have the interesting subject, the log would
show:
2000/08/08 21:26:14 Mail from John Doe <[EMAIL PROTECTED]>
2000/08/08 21:26:14 To: [EMAIL PROTECTED]
2000/08/08 21:26:14 Subject: This is a boring topic
2000/08/08 21:26:14 deliver[19]: /var/spool/mail/jv
All headers, and the body, of the message are at your disposal, so you
can use all the powers of perl pattern matching for your email
filtering.
Delivery routines
-----------------
Most delivery routines will exit the program with status DELIVERED
unless the attribute "continue=>1" is passed.
* pm_deliver(filename[,attributes])
Deliver to the file. The file is locked during delivery to prevent
data corruption.
* pm_resend(address[,attributes])
Remail to the specifield address.
* pm_pipe_to(command[,attributes])
Pipe the message to the command. A lockfile attribute can be used to
prevent multiple deliveries using the same command at the same time.
Pipe write errors are silently ignored.
* pm_ignore(reason)
Treat as delivered but do noting but logging the reason.
* pm_reject(reason)
The program will exit with status REJECTED to signal the
mail delivery system that the message was rejected.
* pm_log(level,message)
Add a message to the log. A timestamp will be prepended.
Requirements
------------
* Mail::Internet
* LockFile::Simple
* Getopt::Long
