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
