I have a SLES 11 SP1 server that I'm configuring to use postfix/procmail to replace our aging sendmail server. I have everything working except for procmail.
I'm not sure what I'm missing but procmail is not processing a users .procmailrc file.

If I call procmail directly with a sample mail message and the rc file, everything works as expected.

Here is the copy of the main.cf and master.cf files for postfix. What am I doing wrong?

Here is /etc/postfix/main.cf...
