Thanks for the explanation. That part of the log makes sense now. It turns out I had a firewall problem now I can see mail being processed. However, mail is not being deliverd to the users Maildir. pm.log doesn't have entries in it, but accourding to the maillog, mail was sent to procmail for processing. Is procmail the LDA? Here's a copy of the log entry.
Aug 20 00:55:20 server1 postfix/local: 6220B3B0978: to=<firstname.lastname@example.org>, relay=local, delay=0, status=sent (delivered to command: /usr/bin/procmail -f-)
BTW, how do I intercept or forward admispconfig e-mails? I changed all references in the control panel that I could find.
