Not one message in these reports authenticated

What it means

All N messages seen for example.com failed both aligned SPF and aligned DKIM. Either your authentication is not published at all, or the domain in your From address does not match what your servers are signing and sending as.

How to fix it

Run the full checkup on the domain first, this pattern almost always means a missing DKIM signature or an SPF record that covers the envelope domain rather than the one your recipients see.

Check your own domain

This page describes the condition. To find out whether your domain has it, run the RUA test or the full checkup, which examines every record at once.

Understand it properly

This page covers one condition. For the whole picture, The DMARC guide, including how reporting works, or start at the Health Library.

Where this comes from

We judge this against RFC 9989 section 4.4. Every finding on this site cites the specification behind it so you can check the work rather than take our word for it.

Other RUA conditions

• You are ready to turn enforcement on
• Some of this is forwarded mail, not an attack
• Somebody is sending as you, and it is being delivered
• Unauthenticated mail is getting past your policy
• Your policy stopped forged mail
