You missed an important point -- for any From: address that has a quarantine or reject DMARC policy, the IETF lists rewrite the address into the dmarc.ietf.org domain using a kludge I suggested to them. You shouldn't be seeing any mail from IETF lists failing dmarc with a dmarc policy. You'll see plenty that fails with p=none (this one probably) but any spam filter that rejects on DMARC failure with p=none is pretty badly broken. _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
