Should do the trick. 

Actually, it's a never-ending battle.  And it's
tricky to fight.  And, as you've seen, a lot of
people have opinions. 

So far, I've tried:

a] blocking entire countries with ACL's.
b] SpamAssasssin + Amavisd + Dual-Sendmail
c] Greylisting with Perl + Mysql + Sendmail
    (excluding a lot of big SP's, thank you much)

It frankly takes more of my time than it's worth,
and that's an economic issue, to be sure.  I'm beginning
to think that, if you have time to spend on it, b] isn't
such a bad option.  But I've not found the *answer*
yet.

Good luck.
