There aren't many services that support e2e encryption though. I've been a Protonmail user for years and only remember being able to send encrypted emails to other PM users, maybe Fastmail also supports the same protocols?
Regardless, if I'm not mistaken encryption protocols are layered on and not part of the official email spec. I'm not 100% on that so may it was added to the spec as an optional feature, but by no means is it common (especially with the market share Gmail owns).
- behringer 3y agoPGP supports all email carriers. But there's also server side encryption that is end to end. If both the sender and recipient uses a trusted mail server that uses encryption then nobody between the two can see the email.
- protonmail 3y agoHi! PGP is open source, and therefore Proton Mail's encryption is interoperable with anyone who uses PGP to encrypt their emails: https://proton.me/blog/what-is-pgp-encryption https://proton.me/blog/what-is-pgp-encryption. Proton Mail also allows you to send password-protected emails to anyone: https://proton.me/support/open-password-protected-emails https://proton.me/support/open-password-protected-emails.
- _heimdall 3y agoPGP is its own protocol though, right? Meaning it is an optional addition to email and not part of the email spec at all?
- behringer 3y agoI guess I fail to see the relevance between the distinction. If you want end to end encryption, both ends can just run their own email servers.
- protonmail 3y agoYes, but all emails exchanged between two Proton accounts, as well as between a Proton account and a non-Proton user who relies on PGP encryption, are protected by PGP.
