@can Unfortunately, only FastMail supports it.

Neither Thunderbird nor major players like Gmail and Microsoft support it, as they obviously push their own proprietary protocols.

So there is not much hope of innovation outside of these players. I would say Inbox could have only existed because it was not using IMAP.
