    present, ending -all

    Hard fail. The strictest setting and the right one once you are confident every sender is listed.

    A policy that actually instructs receivers, which is more than most senders publish.

    keys published on 5 selectors

    A key existing is not the same as working. Read a real received header and check the d= value matches your before you call this done.

    Part platform, part you

    The key is Mailchimp's to publish and it has. Whether it signs the domain in your is yours to confirm, and cannot show it — send one campaign to yourself and look for =pass header.d=oatly.com in the Authentication-Results header.

  • Context

    Receiving mail via Microsoft 365

    Where you receive mail says nothing about where you send it. Marketing sends usually leave through a different platform entirely.

    MX records present.

    oatly-com.mail.protection.outlook.com
Where this comes from. Public DNS, and nothing else. We read the same TXT and MX records any mail server reads before accepting a message, on the days someone looked. There is no scan, no login, no mail, and no score here — only what was published and the date we saw it. Gaps are days we did not get a clean answer from a resolver, and we would rather leave those blank than guess at them.
