Brad misunderstood or misstated what I do. I don't ban the domain (aol.com),
I ban the user (AOLoser at aol.com).

I know this next gets a little away from Mailman and I can't say for other
MTAs but it's simple to do in Postfix:

In main.cf:
 check_sender_access hash:/etc/postfix/sender_checks,

In sender_checks:
# This file has to be "compiled" with "postmap" -
# $ postmap hash:sender_checks
# Sender is SMTP FROM argument

# AOLoser at aol.com banned for AOL TOS notice - 10/20/05
AOLoser at aol.com               554 You have previously reported requested
mail from here as SPAM - you are banned from this server (see
http://www.stonejongleux.com/spamban.html - 10/20/05)

(note that the above needs to be one line in the actual sender_checks file)
