This makes it possible for Gmail to go to p=reject and say to others "Hey, just deploy ARC." Theoretically that will work, but in practice I have my doubts because: 1. It requires all the list servers out there to deploy it, and getting people to upgrade software is non-trivial 2. It requires email receivers to validate ARC. Even if a List Server deploys it, it won't make a different unless we have critical mass of receivers adopting it So, certainly Google + AOL + Yahoo (?) + Microsoft implementing ARC is great, and they have a lot of mailboxes, but it's unclear that their coverage is broad enough. I think we will be in a hybrid state for a long time wherein we will be supporting multiple solutions - (1) ARC for the long term, and (2) skipping DMARC enforcement for known mailing lists. --Terry _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
