I think the reliance upon list operators is properly placed on that role. It's not a DMARC problem, it's a DKIM problem, I think.

No, it's a DMARC problem. DKIM didn't cause any problems for mailing lists (ignoring ill-advised and never used ADSP) until DMARC was layered on top of it, and AOL and Yahoo abused it to foist the support costs on the rest of the world after they let crooks steal their users' address books.


That's how it happened. Can we now accept their push? After so many email addresses became public, how about accepting that email addresses being public doesn't have to imply that anyone can impersonate them? Their move forced DMARC into a role that it wasn't design to play, but perhaps it's not so bad after all...?
