DMARC version tag is not first

CODE RED

DMARC · Critical · costs 40 points · RFC 9989 section 4.8

What it means

v=DMARC1 must be the first tag in the record. When it is not, receivers ignore the whole record, including your policy.

How to fix it

Move v=DMARC1 to the very start: v=DMARC1; p=…; rua=…

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 9989 section 4.8. 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_V_OUT_OF_ORDER

Every fix on this site is yours to implement. If you would rather someone did it, I take this work directly.
