Running postfix-3.2.4 on Slackware-14.2. My server and workstation are on the same host. Yesterday, about mid-day, messages to me stopped being delivered to my INBOX. /var/spool/mail shows:
-rw-rw---- 1 rshepard mail 207100 Jan 15 12:30 /var/spool/mail/rshepard Messages from mail lists are directed by procmail's recipes.rc to the proper file in ~/mail/. I've temporarily directed all incoming messages directed to me at my business domain (same as used to send this message) to the file for messages sent to my personal domain. Yesterday morning I added a couple of domains to rhsbl_sender_exceptions and postgrey_whitelist_clients and processed the changed files with postmap. These are the only changes I've made in /etc/postfix/. Stopping and restarting postfix does not fix this issue, and I noticed the problem only this morning when I logged in and found no log reports or spam that the filters missed. In the 20+ years I've run postfix this has not before happened and I've no idea how to identify the source of the issue. Please advise me on how I can find the problem. TIA, Rich
