A lot of messaging systems try to reinvent the email system but many (signal, matrix, xmpp) took over one key traditional design which we actually dropped while retaining SMTP/IMAP compatibility: server-controlled identities.

With #chatmail user identities are cryptographic and reside on end user devices only. Servers are only message relays and have no control over identities or chats, only perform fast message routing. See this fosdem talk by one of our lead developers https://mirror.cyberbits.eu/fosdem/2026/ud2218a/3F9VTU-deltachat-chatmail-relays-multi-transport.av1.webm

Hi @delta
You wrote :

Is it similar as the solution developed by #Jami #hubzilla #simplex or #nostr ? A kind of p2p with relay network?

I'm not an expert on these, but this feels very much like what nostr people have achieved. Like identity sovereign and servers are just relays. Something like that. Maybe u should check those out and collab if possible

@delta Reminds me of SimpleX, if you can add quantum-resistant encryption and easy multi profile management and throwaway (incognito) profiles like simplex then the privacy and anonymity features would probably be on par and I'd consider switching to get away from the far right dev team.

@delta this reminds me of #nostr. what happens when a user looses the key on the device, is the identity gone?

@nathanael when you loose the last copy of your chat profile then the identity is gone and unrecoverable. However, you can always create a tar file in settings - chats and media - export, or you can setup a second device. Each device is autonomous and does not depend on the original one.

@delta what happens when the identity is compromised? someone got the keys, is there a way to recover from that?

@delta I looked at this, and will use it, but am not quite ready. I am hoping I can get it to work with my own mailserver as the relay.

@delta looks pretty cool but when will you add deniability? (jk) That guy was annoying.
