BIMI is how a brand logo shows next to its mail in supporting inboxes. It takes a TXT record at default._bimi.domain pointing at an SVG logo, usually a verified mark certificate, and above all a DMARC policy set to reject or quarantine. This check reads the record and the DMARC policy. The logo and certificate are not downloaded.
What this checks
Four things, in order: DMARC at p=quarantine or p=reject with pct=100 (and ideally sp= too), consistent SPF/DKIM alignment so DMARC actually passes, an SVG Tiny P/S logo on HTTPS, and for Gmail and Apple Mail a VMC (needs a registered trademark) or a CMC (needs the logo in use for a year). The DNS record itself is the easy part: v=BIMI1; l=logo URL; a=certificate URL at default._bimi.domain. Providers also look at sending reputation, so a new domain may not get the logo even with everything in place.
