Hello, A question I have reading the RFC7489 and more precisely the part «6.6.1 Extract Author Domain». https://datatracker.ietf.org/doc/html/rfc7489#section-6.6.1
The RFC first states: "Messages bearing a single RFC5322.From field containing multiple addresses (and, thus, multiple domain names to be evaluated) are typically rejected because the sorts of mail normally protected by DMARC do not use this format;” And a few lines below: "The case of a syntactically valid multi-valued RFC5322.From field presents a particular challenge. The process in this case is to apply the DMARC check using each of those domains found in the RFC5322.From field as the Author Domain and apply the most strict policy selected among the checks that fail.” I find the two propositions quite contradictory and not sure which one should be applied. Thanks, Damien _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
