Thanks for the response JC. I am checkig with exim and cpanel, to see if they can at least point me in the right direction.
I checked my smtp-failure log in the mailman directory and are seeing hundreds of these.

This is a big clue that the MTA is improperly configured and is trying to deliver to the AOL and Hotmail servers messages for more recipients than those systems allow - triggering anti-spam filtering on the recipient MTA at AOL and Hotmail. The messages are then bounced. My guess is that they changed the MTA at around the same time they upgraded Mailman, and you are barking up the wrong tree to try to find the source of the problem. jc ------------------------------------------------------ Mailman-Users mailing list [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ This message was sent to: [EMAIL PROTECTED] Unsubscribe or change your options at http://mail.python.org/mailman/options/mailman-users/archive%40jab.org
