More about the problem being solved (I had reason to attempt this with Received: headers years ago) than about ARC specifically but, yes, I've read the draft and it makes sense to me. > [email protected] --> [email protected] --> > [email protected] .... > the idea would be that he would also accept messages from > [email protected] to [email protected] > if a positive verification could be made about whether said messages > had really originated from [email protected]. > > The question I have is: Can ARC help that postmaster with doing such a > verification? (Yes/No) Not quite as you've worded it: ARC processing doesn't provide verification of where a message really originated from (yahoo.com in this case), instead it potentially[1] allows a receiver to determine with reasonable certainty who modified it (maybe-we-are-evil.com in this case). With that information the receiver is in a position to make a local decision about whether to ignore the p=reject failure based upon reputation data accumulated by the receiver about the modifying party. - Roland 1: So long as the modifying party performed ARC signing correctly. _______________________________________________ dmarc-discuss mailing list [email protected] http://www.dmarc.org/mailman/listinfo/dmarc-discuss NOTE: Participating in this list means you agree to the DMARC Note Well terms (http://www.dmarc.org/note_well.html)
