Since DMARC needs the results of SPF and DKIM, how does that work? Does DMARC look at the A-R that the other two created or is there a side channel? It occurs to me that a DMARC process has everything needed to make a header that combines all three. >It probably makes sense to stick the sender with the complexity of dealing >with multiple AR fields and combining then, but let's not pretend there's an >overall simplification here. In ARC, definitely. My setup already does a combined header, since I wrote one plugin that calls all three libraries. On my setup (mailfront) it was a lot easier than doing it separately.
