Does anyone know of any other E2EE email provider that offers a locally running IMAP bridge like Proton Mail does?

From what I've seen, other services either don't provide third-party client integration at all (Tuta) or allow direct IMAP access without the need of a bridge — which sounds to me like emails have to be decrypted server-side, so that can't be real E2EE right?

@plbrault it’s not what you asked, but just a few toots back I was reading https://hachyderm.io/@inthehands/113838748643392539 which might be relevant for you

Given Proton Mail’s fashiness coming out of the woodwork, lots of folks are looking at switching away — but they have a reasonable concern: Aren’t Proton Mail’s privacy features special, different from a normal mail provider? AFAICT, the answer is yes in •theory•, but you aren’t giving up that much in •practice•. Short 🧵 surfacing notes I put in a reply — and likely containing inaccurations about Proton Mail, so please correct me if you have better info! 1/

@plbrault #Posteo can be set up to encrypt plain text messages with your pgp public key and you can use #openpgp for E2EE by using for example #Thunderbird
