BIMI — an email specification that lets a domain publish a brand logo in DNS for supporting mailbox providers to display after required authentication and policy checks.
The mechanism complements SPF, DKIM, DMARC, or TLS and addresses a separate need, such as preserving authentication through forwarding, validating a brand, defining an encryption policy, or reporting failures. It does not replace baseline email authentication.
BIMI — an email specification that lets a domain publish a brand logo in DNS for supporting mailbox providers to display after required authentication and policy checks.
It conveys an additional verifiable signal between sender and receiver when ordinary authentication or transport encryption is insufficient for a specific delivery scenario.
Establish correct DNS, SPF, DKIM, DMARC, and TLS first, then satisfy the selected specification. Verify reports and actual message headers, not only the presence of a DNS record.
