ATTN SMART #PRIVACY SOFTWARE DEVELOPERS (I’m not one of them):

We all know email is not the best solution for private communication.

Rather than patch up a weak protocol (like the good work Proton is doing), can other privacy technologies and protocols — like XMPP, Signal, etc. — be tinkered with and reshaped to look like email?

I’d like something that feels appropriate for long-form communications. I want it to look like email, with simple addresses (XMPP has this) and folders and tags — maybe even a calendar — and be available on mobile and desktop. Something where contacts and messages are kept private — stored on local devices and/or encrypted.

Surely others have considered this kind of email replacement. Right? Or is it impossible?
