DMARC uses both when computing alignment and verification, but the From: header is the more important of the two. From the DMARC spec: The domain name extracted from a message's RFC5322.From field is the primary identifier in the DMARC mechanism. This identifier is used in conjunction with the results of the underlying authentication technologies to evaluate results under DMARC. > I rewrite the envelope address when forwarding.

It will help some, but I don't think it will solve the problem unless you also rewrite the From: header. To be honest, I haven't put much thought into whether that is a good thing or a bad thing. > It is great that AOL is enforcing sending policies, but I find it > unfortunate that they sent the message from 64.236.82.2 which has no > reverse resolution! For their purposes, whether or not that IP reverse resolves really has no bearing on whether they think you are spoofing their email addresses. ...Todd -- The total budget at all receivers for solving senders' problems is $0.
