Antigen SPAM Gateway

Have you ever had the feeling that all your spam (millions of mails a week, usually up to 95% of all mail traffic) are caused by a very small number of people or viruses? Makes you wonder if it wouldn't be easier to just eliminate spam at the source. Sadly, laws are sketchy and are "impotent" (at best) and in need of "v1eagr4" when it comes to the issue of spammers.

Still, SMTP gateways, greylisting, tarpitting, stuttering SMTP responses, RBLs, antivirus software and such do a pretty good job, keeping spam under 1% (better results are achievable at the risk of eliminating actual requested or regular messages).
