well, I find that extensive blocking in IMGate plus quick and easy whitelisting to be effective and manageable. However, today I am fighting a bitch, aka earthlink, because earthlink is 1) heavily used by spammers forging @sender.domain and 2) earthlink really IS a source of abuse, gets into RBL, and gets harvested by my new "intelligent" IMGate scripts for direct bad behavior against an IMGate MX. So, in this case, we have to whitelist the justifiably blacklisted earthlink ip's and expose users behind IMGate to abuse from earthlink, mixed in with valid mail from earthlink. Simply no way to distinguish between the two reliably.
