Stop Exchange 2003 from sending "unknown user" emails..
Posted on 2004-08-04
Like everyone else on the planet, my server gets spammed to oblivion... however, my SBS2003 insists on sending messages back to the spammers with "unknown user" - and a copy of the SPAM!!
I'd much rather silently drop these messages - how do I do that?
also, I guess, is there a good alternative to Spam assassin for Exchange 2k3?
