Whenever you allow someone other then yourself to send messages through
your server you have the potential for people to send spam through your
mail system.

Since you mention formmail, but are still not sure about 'where' the spam
is coming from you should post the headers one of the 'spam' messages sent
through your system. You gotta figure out where the problem is coming from
before you can fix it.

What measures are you using to limit who has the ability to relay through
your system?
