It took me a while to understand why ARC works the way it does but now that I do, I don't think anything simpler would do. In particular, anything that lets you say "I'm a mailing list" is out since spammers can do that too. Also, real mailing lists tend to have lousy spam filtering and leak a lot of spam, so you can't just whitelist everything from even real lists. -- Regards, John Levine, jo...@taugh.com, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
