That picture can get even more compelling by comparing DMARC's core with SPF policies as historically proposed. It was well known that SPF breaks forwarding while ADSP breaks mailing lists. DMARC chose to err on the ADSP side, by confining SPF to an auxiliary author's domain verification role. One might malign that forwarding is requisite for free-mail providers who draw users among people who already own a mailbox somewhere. However, I'm for a teleonomic view, where chance and necessity determine the selection of fitter coalitions of structures and functions. The outcome favors for-profit systems because that is (still) what our society is built upon. If IETF, ISOC, or open-source movements aim at promoting a different model of human cooperation, I regret to conclude that the likely negative answer to the question in the subject is to be considered something of a defeat.

I'm neither a lawyer nor an ML admin, so I'm not going to claim damage. Yet, like most of us, I'll be harmed if MLs stop working well. > I also wonder whether the IETF and ISOC have, or should seek, legal > advice about how to keep adequate distance between themselves and > this situation should some relevant jurisdiction initiate an > investigation or enforcement action. Rather than rebuffing responsibility, I'd expect the IETF to invent something new, which works much like ML used to, but is compatible with DMARC. Yes, we may continue to call them "mailing lists". The alternative, to blame domains which follow the leading trend, doesn't seem to be very promising... Ale
