For directly blocking mail however, you'd be better of using the

no false positives. I don't know how they do it, but it catches
90% of my
spam on it's own. More info can be found on http://www.spamhaus.org
The proiblem of using RBLs on SMTP-time is that the mail is gone,
nevertheless it was UCE or not. This becomes even more problematic, as
postfix currently can't weight this information. The implementation
of a
policy filter we are currently implementing for lists.d.o will do SA
like scoring of RBL data and us that information whether to greylist a
mail or not.
