False. Mailing lists only have an obvious problem if p=reject is published, but DMARC doesn't say that you can't differentiate between aligned mail and unaligned mail, only that you can't differentiate between a failed signature verification and no signature at all. Sites can and do assign negative spam points to verified signatures, so there is a (smaller, but still real) problem for MLs even if nobody publishes p=reject. _______________________________________________ dmarc mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmarc
