RBLs are only effective against perhaps 50% of spam traffic, because
so much of it comes from never-seen-before zombies.

I'm seeing 80%-90% of spam blocked by the Spamhaus ZEN list, which
includes the PBL for blocking home computers, infected or not.

Sorry, should have added, "Your Results May Vary" :)
