How to fix BIMI

Fix or remove a malformed BIMI TXT record. BIMI is optional and never required for a healthy sender.

You got BIMI record is malformed. This is informational. BIMI does not affect whether Lumail will send, and it is not required for sender health.

A BIMI record is present at default._bimi.your-domain.com but it is not a valid v=BIMI1 record with an https logo URL.

What to change

Either:

  1. Remove the default._bimi TXT if you are not using BIMI. The alert goes away.
  2. Fix it to a valid record:
TypeHostValue
TXTdefault._bimiv=BIMI1; l=https://yourdomain.com/logo.svg

The l= URL must be https, publicly reachable, and a SVG Tiny PS logo. Most senders also need a VMC before Gmail shows the logo. You can skip BIMI entirely.
