This question is an operational one that is out of scope for a protocol specification whose purpose is to facilitate interoperation of mechanisms (software).

ARC is still an experiment, working out whether it should pass through IETF as part of DMARC or as a separate specification is probably a little premature at this moment. I'd suggest that there are arguments both for and against doing so. - Roland _______________________________________________ dmarc-discuss mailing list dmarc-discuss@dmarc.org 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)
