DMARC version tag is wrong
CODE REDWhat it means
The version must be exactly v=DMARC1, case included. Anything else and receivers ignore the entire record, every other tag you have set is irrelevant.
How to fix it
Set the first tag to exactly v=DMARC1 (uppercase DMARC, digit one).
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_CASE_INVALID
Every fix on this site is yours to implement. If you would rather someone did it, I take this work directly.
