What is the trick to get Postfix's local command to pipe mail through procmail?

I have:

-bash-4.1$ grep allow_mail_to_commands /etc/postfix/main.cf allow_mail_to_commands = alias, forward

and

-bash-4.1$ cat .forward |/usr/bin/procmail

and a .procmailrc file:

-bash-4.1$ cat .procmailrc PATH=/usr/bsd:/bin:/usr/bin:/exp/rcf/share/bin MAILDIR=/var/lib/amanda/Mail #you'd better make sure it exists DEFAULT=$ORGMAIL #completely optional LOGFILE=$MAILDIR/from #recommended

• ^From.*no-reply@sns.amazonaws.com

|$HOME/retrieveArchive.tcl

:0 ! heller@deepsoft.com

Basically I want all mail to the Amanda Backup account, except messages from Amazon SNS, to be forwarded to me (the system admin). The retrieveArchive.tcl is a script to process Amazon SNS messages.

It's this simple:

Instead of putting a call to procmail in your .forward, first, set up /etc/postfix/main.cf with the following line:

mailbox_command = /usr/bin/procmail

and reload postfix. Now, postfix will default to using procmail as its local delivery agent.

Now, set up /etc/procmailrc like so:

USER=`whoami`

:0 fw | spamc

:0 e { EXITCODE=$? }

Now, set up the amanda user's .procmailrc rules like so:

:0: * ^From.*no-reply@sns.amazonaws.com |$HOME/retrieveArchive.tcl

:0: * ! heller@deepsoft.com

Voila!
