Is there anyway to only permit mail for a specific pseudo name to only originate from users on the local network? My pseudo name "everyone" has been caught by a spammer and "everyone" gets the same spam messages. If mail destined to "everyone@mydomain.com" were have a way to check that the user either 1)was on the local subnet, or 2)had a valid username/password when sending mail, we'd have a fix!
