Hi all,
I have tightened up my exchange server so there is no relaying, etc and I think it is setup the correct way to keep spam from originating from my server.
I think that a user may have some sort of spyware/trojan that is sending out spam from within our network. How do I make it so that the only outbound email permitted is from our exchange server? In other words, how do I block emails from the individual workstations?
