DMARC version tag is not first
CODE REDWhat 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.
