I think an intelligent application of RBL's is what's missing in a lot of

I still get tons of SPAM via my ISP (although the amount that they're 
syphoning into the Spam folder at their end seems to have diminished).  I 
get none through my own server which uses greylisting - a very effective 
idea for small email servers - I get an awful lot of "unexpected 
disconnectsion"s from spammers that are asked to wait :-)
