I've noticed that, even though RFC7489 appendix C states that the
'envelope_from' element has a minOccurs of '1', this element is missing
quite frequently. This is probably due to the fact that some messages have a
'null reverse-path'. The RFC5321 (Simple Mail Transfer Protocol) chapter
4.5.5 allows a 'null reverse-path' ("<>") to be used for non-delivery
notifications, delivery status notifications and message disposition
notifications.So what to do? Should messages with a null reverse-path be excluded in DMARC rua reports or should the minOccurs value of the 'envelope_from' element be changed from '1' to '0'? -- Freddie Leeman _______________________________________________ dmarc mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmarc
