We recently (maybe 30 minutes ago) had someone forward a LOT of mail
through our server... most of it seemed to be destined for every user
on aol.com starting with the letter a.

What's the Q&D patch to sendmail.cf to stop people from being able to
forward mail through? Can that be restricted by domain? (ie only people
from my domain can forward mail)....
