It is openpgp, but I’m not aware of another mail provider that allows you to encrypt every mail when it arrives. Mailbox.org does have to manage this key though of course, but it can be a separate one from what you use to sign / encrypt sent emails.
full mailbox encryption
still support regular imap
Hmmm, how? For me, it sounds like they are either talking about OpenPGP which everyone can use OR it’s, sniff, bs.

The way it works is that it’s encrypted server side with your password.
If the server isn’t infected, they can’t read your email. If the webmail server is infection, they could store your password on author (instead of just hashing it immediately) and decrypt your email.
The mitigation to this risk of server integrity compromise is PGP

Okay. New mail arrives. Plaintext, SMTP. You have not logged in today. To store it, it needs to know your password…
About as good as a gate in the middle of a field. Better just use POP3.

No, that’s not how it works. If you set up mailbox encryption (mailbox guard), you set up (or let mailbox.org generate) a pgp keypair. Any time you want to read an email, you have to unlock the key first. This way you can use regular imap, the body of emails will just arrive encrypted (and optionally the subjects as well I believe), you only need a pgp decryption tool to read the mails (which Thunderbird/K9 supports out of the box (with OpenKeychain on Android)).

Right. A user from another server sends you mail. The mail is unencrypted on their side because they don’t know your key yet, or they don’t know how to use OpenPGP, or it’s automated.
Servers talk SMTP between each other, not just a client sending mail.
The round trip time in this protocol is fucking insane, but that’s what the people in the year 1980 thought of. They never thought this would be used outside of universities.
Anyways, inevitably,
mail.mailbox.orggets the message, unencrypted. It can encrypt it later, needs the key though.
