This will allow your mail.ru members to receive messages sent through us. Relatedly, it does seem like the expectation these days is for mailing list software to re-write the From line when p=none (not just reject/quarantine, which is what we currently do). It is not uncommon for us to get enquiries from people setting up DMARC for their domains. They start with p=none, see a bunch of reports about email sent through us failing that, and then contact us about it, understandably thinking it's something that they need to contact us about fixing before they move to a more strict setting. For others here running mailing lists that pay attention to DMARC settings, do you treat p=none differently than reject/quarantine? Thanks, Mark
