John is correct. There is no consensus on how mailing lists should deal with DMARC problems, notwithstanding what rfc6377 says about DKIM. ADSP never gained enough real world implementation for there to be a meaningful consensus. One need only look at the discussion threads on the IETF (and other) list(s) following the publication of DMARC p=reject by several large mailbox providers to see the diverse range of views. While I disagree with John on some things, in this case he is 100% dead on. To pretend otherwise is to do a disservice to the mailing list community and the mail community at large.
