Hi,

   Lately I am having problem with spammers who change their mailfrom
(I have spamguard which can block spammer by e-mail) with each message
they send and the same time they send only one e-mail in a connection
so tarpitting is not working with them. Does any one have a valid
solution other than using something like spamassassin. I need
something that should work on the network level not the smtp level and
with minimum load.
   

Have you yet explored DNSRBL - i.e. IP-based blocking?

 

I have using this for about a year now, it is effective against known 
spammer. The problem is with spammers on dial-up links.
