No, this is a "single, properly formed RFC5322.From header field": From: [email protected], [email protected] While this is not: From: [email protected] From: [email protected] We have never agreed what to do about From: header fields that have more than one address. My inclination is to say DMARC doesn't apply since they are so rare and there is poor agreement about what they mean, particularly if the addresses are in different domains.
