We (ProtonMail) don't provide a server-side IMAP/SMTP interface because we don't want to see your cleartext mail. And if you are doing the encryption and key management yourself locally, then you can literally use any email provider you want. The Bridge sidesteps this issue by exposing a local IMAP/SMTP interface and handling the encryption/decryption locally, but there are very good reasons we built it the way we did.

I don't think those are very good reasons for doing what you did, since the set of users not using protonmail is orders of magnitude larger than the set of users that do, so protonmail is basically just covering a very small edge case (communication between protonmail customers) while making it more difficult to use the more common case of communication with folks that do not use protonmail.
