This all habit of telling other actors what they should or must do has to stop. This hubris is the original sin of Yahoo, which started all the trouble. In a sound interoperation situation, each actor has a bit of wiggle room to assess the situation in their own area of responsibility according to their worldview. Which means for example: * originating domains are free to choose their preferred treatment of DMARC FAILing messages, while remembering to be careful what they wish… * mailing lists can send as their own domain if or when they act as a proper editor, but can also keep the original From field when they act as a technical helper. And they don't need to second-guess evaluators. * evaluators make the final delivery decision based on the originating domain's wishes, but most of all based on their assessment of their users' interest. And yes, they can rewrite whichever headers they feel like, they control their own UX. Corollary to this freedom, there must be incentives to keep each actor accountable. This is where the problem currently lies: the originating domains take no responsibility at all for their choices, which is why Yahoo could get away so easily with their disruptive move. That's why I suggest that REJECTed messages should be silently discarded and thus possibly lost, which makes all actors equally bear the consequences, instead of bounced, which disproportionately punishes the mailing list operators. If it decreases deliverability in the short term, so be it: making all actors accountable is a prerequisite for any consensual solution in the long term.
