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.
