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.

Is this attached to the bounce backs I am getting which usually say 550 REQUESTED ACTION DNS Failure
Thanks for any help in advance

Hi Richard,
Here is what I know so far, mail for most list members seem to be going
through for the most part. About two weeks ago MM mass unscribed about
300 folx. Now we seem to have stablized the members but the owners of the lists are getting routinely bounced. Yahoo email address do not have a problem, aol is a major headache as is hotmail.
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.
