Going to Extremes to Fight Spam

http://www.wired.com/news/technology/0,1282,57867,00.html

Please take a look at wired.com and read about fighting spam.

 

I still feel that there is a need of some sort of mechanisme to check if a mail is comming from a known spammer adres. And we also need the checking methode if the user is sending from its own domain and out of its own name.

Return-path: <Yoshi4184@Yoshi4184.MyIP.org>

Received: from yoshi[192.168.0.102]
 by yoshi4184.myip.org [192.168.0.103]
 with SMTP (MDaemon.PRO.v5.0.4.R)
