Thank you, we've put a ton of work into this. Not only are your mailboxes encrypted with SQLite using ChaCha20-Poly1305 [1], but you can also now add an OpenPGP key [2] (for double encryption).

We support SMTP, POP3, IMAP, API, webhooks, regular expressions, and more.

Sorry; I was being unnecessarily ironic because there really is no "quantum safe" things yet. Otherwise nice work; always nice to see more competition in this space!

RE: Competition:

We are the *only* email service provider that is 100% open-source. Proton Mail [1], Skiff [2], and Tuta [3] all have closed-source back-ends, despite advertising as closed-source.

RE: Quantum Safe:

ChaCha20-Poly1305 is generally considered to be quantum safe [4] [5].

Umm do you have any better sources for the crypto claims than Stack Exchange and Reddit? That's not really putting my mind at ease.

> there really is no "quantum safe" things yet

What about, e.g., OpenSSH's post-quantum key exchange [email protected]?

> [email protected]?

I am not an expert in this space but, as far as I can tell, these are all work-in-progress, as is quantum computing itself. There are several research groups and committees involved, including at, say, IETF and the like.
