blocking unauthorized mail relaying (i.e. spam)
Is there a similar utility/technique for Zmailer 2.2x (toronto version)
that blocks unwanted mail relaying? I'm trying to find the quickest
way to do this without revamping our mail systems. Can I just compile
the smtpserver and hope that it will be compatible with the other
components still at version 2.2x?
