I'm confused. I thought we all agreed that From represents the author who is responsible for the content, and consequently it had importance to both the filtering process and the user. I thought the issue at hand was that DMARC-induced header munging made the From address into something different then the address which best represents the author. So it seemed like we had a lot to agree on.
Also, I thought a trust indicator was a statement like "The From Address is DMARC-verified", rather than "This message is from user@domain" Which leads me to several questions - Does the research support the idea that the From address is a trust indicator? - Is so, does it show that the only purpose of the From address is as a trust indicator? - If "From" has purposes other than as a trust indicator, does it matter whether the value is correct or not? - If it is true that the From address serves no purpose to the user, then is header munging really a problem?

Except they aren't both right. We know that it is used by filtering engines. There is no evidence it is used by end-users. And there is a pretty long history indicating such information is NOT used by end users. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net _______________________________________________ dmarc mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmarc
