Add BIMI support to Mailserver

[imc67]

More and more mail clients are supporting BIMI for for digital certifying mails and show logo as proof.

What is BIMI?
Brand Indicators for Message Identification or BIMI (pronounced: Bih-mee) is an emerging email specification that enables the use of brand-controlled logos within supporting email clients. BIMI leverages the work an organization has put into deploying DMARC protection, by bringing brand logos to the customer’s inbox. For the brand’s logo to be displayed, the email must pass DMARC authentication checks, ensuring that the organization’s domain has not been impersonated.

With BIMI you can:
Display your logos on your emails.
Control the logos that display with your email messages.
Cultivate immediate brand recognition and enhanced user experience.

I have never heard of this standard before or seen it somewhere out in the wild. Are there some screenshots you might be able to share so I can get a better understand what this is for?
