It helps in judging that, but isn't complete by itself (you still need a reputation system for the intermediaries). > And if it is such, shouldn't it be part of the DMARC standard? I think it is separate because DMARC is directed to solving a problem for email originators, whereas ARC is directed to mail list operators to help mitigate the consequences of DMARC for them. Of course both impose mechanisms on email destinations; but the goal is that these additional mechanisms can improve the quality of the classification results (spam versus ham) applied to their user's inboxes. -- Shal _______________________________________________ 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)
