Yes, individuals can also be blacklisted by AOL. For example, I have a
subscriber on a list who can post from either of two addresses, say A
and B. When he posts from A there is no problem. When he posts from B,
every non-digest AOL subscriber bounces, but hes only done this a few
times so no one has been disabled and I haven't seen the actual bounce
message to know if it is the same as yours. I guessed it was based on
address B in the From: header, but it could be an IP in a Received:
header I suppose.

You could easily determine whether it is your Mailman IP or the sender
by posting to the list from another address.
