You are ready to turn enforcement on

What it means

N% of the mail in N days of reports authenticates and aligns, and none of the failures are yours. Staying at p=none now means collecting evidence you have already acted on while anyone can still send as example.com.

How to fix it

Move to p=quarantine with pct=25, watch a week of reports, then raise to pct=100 and finally to p=reject. Change one thing at a time so any surprise is easy to attribute.

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 9990 section 9.2. 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

• 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
• Your own mail is failing authentication
• Reports are arriving, but nothing is being stopped
