I`ve a huge increase in Spam as well
I`m looking at Postgrey for my new mailserver but
undecided !!

But for emails from Countries that I know that I won`t
get from , I use
http://www.blackholes.us/zones/countries/

Even now these spammers are getting around this 
with other IPs(Zombie machines)
I wish for a good soln as well

The only problem with an automatic way is that
you could blacklist IPs that you shouldn`t
It happened to me yesterday ;->
C`est la vie !!
