Re: Spammers answering TMDA Queries

how many of us are now sending with DKIM or Microsoft's scheme? It  
might be worthwhile making ietf.org apply a policy to senders that  
would recognize normal participants and disallow known spam domains.

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?

R's,
John
