In any case, it's still a lot better than no encryption at rest at all, as with most e-mail providers :-)

By the way, the Proton "UX" is far superior than Mailbox.org - which i personally find hard to navigate / disorganized.

Yes seems to be exactly the same as mailbox.org but with their own stuff rather than PGP.

"Zero access" is misleading here and I would leave it out. Encryption doesnt allow access, otherwise it would be "incomplete encryption".

Sounds kinda like a term they made up. They do have access, before they encrypt it.

About the sponsor #Proton, what does "zero access" mean?

As #eMail is not #e2ee encrypted normally, they will get unencrypted emails and encrypt them before storing them.

This is not zero access in my opinion, as they could access everything if they wanted. But the data is encrypted at rest, which is nice also if law enforcement would subpoena them, as that is all they can do most of the time.

@mailbox_org is pretty open about how they do that, they just use #PGP. I guess Proton and Tuta does something similar.
