What I want is an open-source proxy that I can install on localhost to provide IMAP/SMTP access on the one side, and talk to the encrypted remote data store on the other side.
All of the encrypted email services I've seen so far, including Protonmail and now Lavabit v2, require using a special client (app or webmail) instead of common email software. This fails the very first test that I apply when trying to decide whether or not to use an online service: can I get all my data out of it on short notice, in a standard format through an automated process?
For email, this means IMAP access so that I can use standard tools like imapcopy to back up and migrate my mailbox. I don't care how secure your product is if it leads to vendor lock-in. I want both good encryption and an exit strategy, and the latter is much more important because if you screw up, I can always move to someone who does it better.
