>I don't see any solution to this problem other than abandoning DMARC. It is my impression that the number of sites that send legitimate mail that DMARC cannot describe is not enormous. Yahoo's blog estimated that the number of systems they broke is on the order of 30,000.
It would cost something to fund a shared DMARC exception whitelist, but assuming it was funded by members of the DMARC group, that would both solve the problem and put the costs where they belong. It is also my distinct impression that Gmail and Yahoo, at least, have a pretty good idea of who those systems are, so the whitelist could be pre-seeded so for most list managers, all they'd see would be that their list mail resumed working the way it used to.
