The most sane way to deal with systems that reject or otherwise discard mail that fails DMARC checks is to rewrite the From. However, for other people, is a regression for various reasons. So the only sensible way forward is to have a per subscriber option. >>Or are you saying that at the moment 40% of the subscribers of IETF >>lists reject >>or otherwise not receive mail from DMARC protected senders? > >The 40% was statistics about one IETF mailing list only.

So is that one mailing list typical, or just a bunch of people who like to reject mail? But apart from that, you are saying that for at least that one list, if you send a mail to the list with a 'p=reject' then 40% of the subscribers are not going to see that message.
