A policy of "none" isn't useless to an evaluator; it's communicating to the evaluator that the domain owner isn't yet confident that all mail sent using its domain in the RFC5322.From header is properly authenticated, and so messages that fail the DMARC mechanism check should not be automatically assumed to be unauthorized.
Yes, p=none can mean that. Or it can mean that the domain owner, despite being below a PSD which imposes DMARC hard policies, doesn't want to participate at all. Or it can mean that a relevant percentage of the domain's mail traffic goes through mailing lists; hence, although all mail sent using its domain in the RFC5322.From header is properly authenticated at the first hop, it would be misleading to assert a hard policy in general.
We're overloading p=none with too many meanings. Best Ale -- _______________________________________________ dmarc mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmarc
