When emails are imported from external providers such as Gmail or other IMAP accounts into Proton Mail, the sender's avatar is often missing or replaced with a generic placeholder. It would be a great enhancement if Proton could automatically fetch and display BIMI (Brand Indicators for Message Identification) logos for imported emails whenever the original sender's domain publishes a valid BIMI record.

This would make imported conversations feel more native, improve visual consistency, and help users quickly recognize legitimate brands without relying solely on the sender name or email address
