FYI, the IETF's mail relay for role accounts like WG chairs breaks DKIM signatures. It's a bug, but it took quite a while to realize what the problem was, since some signatures get through OK. It's an old python library helpfully tidying up the message headers. Fixing the bug is nontrivial due to the cruftiness of the surrounding code. See tools-discuss for way more details. In theory relays shouldn't break DKIM, in practice ... R's, John _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
