Hello John, https://tools.ietf.org/html/rfc7489#section-6.1 say .. MUST concatenate these strings ... One may read the example above like "v=DMARC1; p=none v=DMARC1; p=reject" which is invalid thus must be ignored. > Looking through RFC 7489 I don't see anywhere that it says that more > than one record is forbidden. yes, that would make it clear. > For that matter, what if anything does this mean? > > _dmarc.example.com IN TXT "v=DMARC1; p=none; p=reject" I would expect this to be valid but the result depend on the implemented parser thus is not predictable. Could be p=none OR p=reject > In 7489 it says "DMARC records follow the extensible "tag-value" > syntax for DNS-based key records defined in DKIM [DKIM]." ... or this... > I hope that > means they follow the DKIM rule that duplicate tags make the whole > record invalid, but that could be clearer. +1 Andreas _______________________________________________ dmarc mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmarc
