You might find a more receptive forum at ASRG.
Well, maybe. I have no interest in arguments that it's bad to
authenticate mail because people can't send anonymous mail. That
leads briskly to a scenario where anyone can say anything, but it's
pointless because nobody's listening.
There's a variety of ways to send anonymized mail, ranging from web
mail to remailers like mixmaster. If someone wants to propose a
specific topic related to anonymous mail, perhaps a BCP on
anonymizers, I'd be willing to consider it.
