I've been trying to get Postfix to invoke procmail and have not been
successful.
I modified /etc/postfix/main.cf:
mailbox_command = /usr/bin/procmail
master.cf has procmail listed as:
procmail unix - n n - - pipe
flags=R user=nobody argv=/usr/bin/procmail -t -m /etc/procmailrc
${sender} ${recipient}
Where the parameters are:
# service type private unpriv chroot wakeup maxproc command + args
The default wakeup is never.
I have verified that postfix is sending outgoing email and receiving email
for the appropriate domains.
My $HOME/.procmailrc directs all email to various mh folders. On 8.1, the
email was left on /var/spool/mail/gaf
