Um, spammers haven't sent mail from "known spam domains" since about 2001. These days spam has 100% forged return addresses. DKIM and Sender-ID help tell forgeries from legit mail, but I haven't heard anyone say that forged mail purporting to be from list participants is an issue. Unless I am missing something, the amount of spam leaking into IETF lists is currently about zero. What problem are we trying to solve?
