It has been so since late 2015, according to the DMARC Consortium. At that time they claimed that 80% of legitimate email was originated at domains that participate in DMARC reporting protocols. I don't think p=reject will ever be the norm for freemail providers. > I also wonder what ARC is going to do to this paradigm. It may or may not help mailing lists. It depends on whether the spammers successfully jump on it to obfuscate themselves, which they could do, in which case you might end up in the current situation where you need to apply for whitelisting at some of the large providers. On the other hand, the large providers are getting better at identifying responsible lists for themselves, and ARC would definitely make authenticating those lists easier.
