BIMI record is malformed
ATTENTIONWhat it means
The record does not begin with v=BIMI1, and receivers are told explicitly not to correct capitalisation or syntax on your behalf. It is ignored as published.
How to fix it
Start the record with exactly v=BIMI1, then l= and optionally a=, separated by semicolons.
Check your own domain
This page describes the condition. To find out whether your domain has it, run the BIMI test or the full checkup, which examines every record at once.
Understand it properly
This page covers one condition. For the whole picture, BIMI, defined, or start at the Health Library.
Where this comes from
We judge this against BIMI draft 14, section 4.3. Every finding on this site cites the specification behind it so you can check the work rather than take our word for it.
