Enforcing DMARC with no visibility
CODE REDWhat it means
example.com is at p=none with no rua address. Receivers are refusing or quarantining mail on your behalf and you have no way to see whose mail it was, including your own.
How to fix it
Add rua=mailto:dmarc@example.com today. If legitimate mail is being blocked, the reports are the only place that shows it.
Check your own domain
This page describes the condition. To find out whether your domain has it, run the DMARC 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, from a first record to enforcement, or start at the Health Library.
Where this comes from
We judge this against RFC 9990 section 3. Every finding on this site cites the specification behind it so you can check the work rather than take our word for it.
Other DMARC conditions
DMARC_BLIND_REJECT
Every fix on this site is yours to implement. If you would rather someone did it, I take this work directly.
