What changed in DMARCdrift, newest first.

  1. Two-factor sign-in, passkeys, and Outlook bounce guidance

    Optional authenticator-app two-factor sign-in with recovery codes, passkeys for sign-in, and a guide to investigating the Outlook.com 550 5.7.1 AS9031519 bounce.

    Two-factor sign-in with recovery codes

    You can now protect your account with an authenticator app (TOTP). Turn it on under Settings. When you enroll, DMARCdrift shows a set of one-time recovery codes so you can still get in if you lose your device. You can regenerate them later from the same page.

    Passkeys

    You can add passkeys under Settings, rename or remove them there, and use one to sign in from the login page.

    Outlook.com 550 5.7.1 AS9031519 guidance

    Some senders, including low-volume domains without a DMARC record, have reported Outlook.com bouncing their mail with 550 5.7.1 and AS9031519. We published a guide to what the diagnostic says, what is and is not established, and how to investigate: Outlook 550 5.7.1 AS9031519. To see which authentication records your sending domain publishes, run it through the free email authentication checker.

    Check your own BIMI

    If you want your logo to show next to your mail, the free BIMI checker shows whether a domain has BIMI configured and which clients can display it. For background, read BIMI explained.
