End to end encrypted? https://delta.chat/en/help#does-delta-chat-support-end-to-end-encryption https://delta.chat/en/help#does-delta-chat-support-end-to-en... Yes, if receiver uses IMAP if I understand this correctly. Edit: End-to-end encryption or not is maybe unrelated to IMAP use. E2E Encryption does not work with some email providers though.

Does that mean the iOS app isn’t encrypted? (Guess I could just go check the source code instead of being lazy)

  Uh, I don't think IMAP is generally blocked on iOS? Anyway, end-to-end encryption seems to depend on the email provider being able to support IMAP. So Hey.com is out but gmail can work if you enable IMAP support for example. Here is a list of tested providers: https://providers.delta.chat/ https://providers.delta.chat/

    IMAP is not blocked by iOS. Also, end-to-end-encryption is not related directly to IMAP. The issue with Hey/Protonmail/Tutanota is that they do not offer IMAP- or other standard-protocol-support - so you can just not log in with Delta Chat (nor with any other e-mail-client) to your Hey/Protonmail/Tutanota account. If you log in to deltachat say with Posteo, you can write to other Hey/Protonmail/Tutanota accounts - but as the recipient cannot use Delta or other Autocrypt capable clients (Enigmail, K9), things cannot be encrypted. If Hey/Protonmail/Tutanota would support Autocrypt in their webclients, of course, this can change.

It does not say anything about IMAP there. It just says that it is in fact end to end encrypted.

  Yeah, but some email providers don't support IMAP and on those it is not end-to-end encrypted. https://delta.chat/en/help#is-delta-chat-compatible-with-protonmail--tutanota--criptext https://delta.chat/en/help#is-delta-chat-compatible-with-pro... https://providers.delta.chat/ https://providers.delta.chat/

    It sucks when mail providers don't support standards like IMAP. Solution: Choose a better mail provider or make a second account with one.

    This is not what I got from the FAQ.

      Yeah, I might have misunderstood things.

no, not specific to IMAP. It's always PGP encrypted unless you disable it. > If you want to rather avoid end-to-end-encrypted e-mails by default, use the corresponding Autocrypt setting in “Settings” or “Advanced settings”.

it depends if the receiver has an autocrypt-capable email client like k9mail, etc. it doesn't have anything to do with IMAP on the receiving end, but Delta Chat currently only supports IMAP so the sender does need a server with IMAP support to use Delta Chat, but the receivers don't even need to have Delta Chat

  Great explanation, sorry for confusing things.
