DarkMail

Zero-access encrypted email for any number of domains. Decrypted only in your browser.

DarkMail is a self-hosted, zero-access encrypted email server. It receives mail over SMTP, checks SPF, DKIM and DMARC, and encrypts every message to its recipient before accepting it. There’s no IMAP or desktop bridge: the web client is the client.

WHAT IT DOES

  • Encrypted on arrival

    Incoming mail is encrypted to the mailbox's OpenPGP key before the server even says "250 OK".

  • Decrypted in the browser

    Messages are only ever decrypted on your device. The server holds ciphertext.

  • End to end where it can be

    Mail between DarkMail mailboxes and other OpenPGP recipients is encrypted and signed in the browser.

  • Any number of domains

    Run mail for every domain you own from one self-hosted server.

  • Signs in with DarkAuth

    Sign-in and key custody come from DarkAuth, so DarkMail never sees a password or a usable private key.

WHERE IT FITS

DarkMail runs on Puzed Platform, so it sits on hardware you own alongside the rest of the Puzed stack.
