Yahoo! and AOL are bigger than MLMs. MLMs would bear the brunt of user rage at that treatment. Really. We now have a couple of decades of experience. The big mailbox providers have our subscribers by the short hairs -- their Internet reputations are intimately tied to those email addresses. If the big provider won't change (and historically they've followed the principle of throw the garbage in their neighbor's yard and protest innocence loudly when users question them), then the subscriber/poster screams at the list owner. They're typically much less attached to their ML subscriptions than to their email addresses, and list owners tend to be much more responsive to their subscribers than big mailbox providers are. We have to jump through their hoops, or at least our list owner constituency thinks they do. I'm an economist even before I'm an MLM developer, I'm willing to go with the market if there is no market failure. But here there is a failure: email address lock-in. On many lists, the AOL and Yahoo! users are a small minority. If "customer is always right" considerations mandate catering to their mailbox providers' DMARC policies, the great majority loses MLM features they value -- but they are unlikely to kick up a corresponding fuss. I'm quite sure that the market test will give the answer "knuckle under", regardless of whether the majority of AOL and Yahoo! users would prefer to keep the current MLM features or not. They don't pay for AOL/Yahoo!/GMail/Hotmail MUA dev costs, so those providers have very little incentive to respond positively to their requests to support MLM features better. And, in fact, they WONTFIX them regularly (dunno about Hotmail, but GMail is as bad as the others in this respect). _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
