Try a few of the cheaper tricks - HELO checks, for example, or greetpause (I'd say graylisting but that has interesting consequences when it comes up against another "cool antispam trick" - sender address callbacks). They'll cut down on a ton of this stuff. AUPs etc are good but believing in the "be generous in what you accept" part of that old saw never got you anywhere... though a certain amount of generosity is called for all right.
Most ARIN ISP's also take it somewhat seriously (legal issues and such)... Except for those big ones, big lawyers thrump reality/truth anytime.
Asiapac ISPs have a rather worse problem but well - theyre not the only ones. Like I said try maawg - the next one is later this month in SFO - www.maawg.org -- Suresh Ramasubramanian (ops.lists@gmail.com)
