that’s absolutely valid, and I’ve come to effectively the same conclusion: good encrypted email is effectively a different protocol (one which, as of now, is proton-to-proton and tuta-to-tuta only) and should be treated as one. daily unencrypted email is a legacy protocol that can effectively be handled client-side as a different account.

encrypted mail should be federated, possibly with something like activitypub (though I don’t have a good solution for attachments), but every time I float this I get a lot of very angry feedback about how I shouldn’t propose a new email standard without solving spam first, whatever solving spam means. some of the people giving feedback then float solutions that are basically warmed-over hashcash and then I stop listening.

the difference between modern webmail and what activitypub already does is very thin — a lot of it is intent, UI (email’s focused on long messages and potentially long threads), and features like attachments going from best-effort priority to crucial. there’s absolutely room in the world for better email — I just believe that internally, it’ll look closer to e2e ActivityPub with something like Soatok’s federated keyserver concept on top, rather than the shitty half baked shit we do now to make PGP work with email
