I'm relaying these DMARC questions/concerns on behalf of an email admin at another university. I quickly searched this list's archives for the Sender header vs DMARC alignment issue and don't see much aside from a conversation in May 2015. Is it worth further discussion and/or an issue in Trac? I think I know the answer to the second concern, but I'll defer to people more adept at explaining the nuance.
See below... Thanks, Jesse Thompson UW-Madison " I don't see on the list of issues the most fundamental problem of DMARC, namely that it conflicts with RFC 5322 on the use of the From and Sender header fields [1] and possibly with RFC 6326 as to the significance of DKIM fail [2]. The former is the more serious problem. Making DMARC alignment part of a standard for Internet messages requires a revision of RFC 5322. I'd love to see this resolved. [1] The "From:" field specifies the author(s) of the message, that is, the mailbox(es) of the person(s) or system(s) responsible for the writing of the message. The "Sender:" field specifies the mailbox of the agent responsible for the actual transmission of the message. [2] signature verification failure does not force rejection of the message; " _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
