This one came through right away. There was a user subscribed to
alfs-discuss and lfs-support that was using an unresolvable domain.
Mailman was attempting to deliver to this user twice every thirty
seconds, and the postfix mail queue was filled with mail headed for this
Forcibly removing the user from the lists and restarting postfix and
mailman _seems_ to have fixed the issue. Although why one unresolvable
domain was causing so much trouble, I'm not sure. I'm looking into it
