Display Brand Indicators for Message Identification (BIMI) #8143

Open candrews opened 2 years ago

candrews commented 2 years ago

Brand Indicator Message Identification (BIMI) is an industry-wide standards effort to use brand logos as indicators to help email recipients recognize and avoid fraudulent messages.

It would be nice if roundcube displayed these images like this mockup shows: gmail with bimi

In short, to get the bimi image, check for a TXT DNS record at default._bimi.. The contents of that record will look like this: v=BIMI1;l=https://www.integralblue.com/logo.svg The l value is the URL of the image, which is always an SVG.

There's a draft (https://datatracker.ietf.org/doc/draft-blank-ietf-bimi/) but I wouldn't call that a standard (yet).

Anyway, sounds like a good idea for a plugin.

For the record, rspamd release 3.2 added a preliminary version of its BIMI plugin. Links of potential interest in case a Roundcube plugin is going to make use of the associated headers and service/helper:

Google, Yahoo!, FastMail, and Pobox now supports BIMI; with other providers considering it.

Here is a PR for BIMI Support, refer to #8759, a tiny contribution from me.

I've submitted an MR that adds a bimi plugin: https://github.com/roundcube/roundcubemail/pull/8860

The plugin supports caching and does svg filtering. I'm eager to receive feedback and :crossed_fingers: get it merged :smile:
