The days of straight RBL based connection rejection for spam filtering are over IMHO, spammers are just too clever now and have too many different methods of attack.

I think that was part of the rationale for SPEWS. They know it's impossible to react quickly enough to stop the spam flooding from relays and proxies, so they block the spam sources instead, with a fair bit of collateral damage (that's the nuts ;-)) so that the ISP takes notice. Lots of people disagree with SPEWS, but it does seem to work to some extent. -- Juha
