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(_at_)Yoshi4184(_dot_)MyIP(_dot_)org>
Received: from yoshi[192.168.0.102]

step 1)
Server recieving e-mail.

step2.1)
check against spam-blacklist-server if 19.168.0.103/yoshi4184.myip.org is a 
trusted mail relay server.
if not --> drop mail to deadletterbox(_at_)domain(_dot_)com 

step2.2) (optional)
check against local maintaind spam-server-blacklist if 
19.168.0.103/yoshi4184.myip.org is a trusted mail relay server.

step 3)
check if 192.168.0.102 is allowd to send in name of @Yoshi4184.MyIP.org

step 4)
check if Yoshi4184(_at_)Yoshi4184(_dot_)MyIP(_dot_)org is a correct account at 
@Yoshi4184.MyIP.org
if not --> drop mail to deadletterbox(_at_)domain(_dot_)com
