Dispatch

Mail. A full IMAP, SMTP and JMAP mail client with a local encrypted store. PGP is automatic between Bunker users and opt-in to outsiders. Reads and composes offline.

A dispatch sent out from the bunker.

WHAT IT DOES

In the app

  • Works with the mail accounts you already have over IMAP, SMTP or JMAP.
  • Keeps the whole mailbox in the vault, so search and reading work with the cable unplugged.
  • PGP without ceremony: automatic between Bunker users, one switch for everyone else.
  • Blocks remote images and tracking pixels by default.
ICEBOX

What lives in the vault

  • Every message, attachment, draft and contact.
  • Your keys and the keys of people you correspond with.

Caution · read this

Mail itself. Sending and receiving need your mail server, so Dispatch talks to it, and only to it, when you tell it to sync or send.

What your mail server sees is what any mail client would show it. Message bodies to Bunker users are PGP-encrypted end to end; to outsiders they are encrypted only if you turn PGP on for them.
