ihasmail documentation

ihasmail is Gmail-class webmail for Stalwart Mail Server: mail, calendars, contacts, files and Sieve filters in one responsive app, speaking JMAP and nothing else. No IMAP, no SMTP, no database of its own. AGPL-3.0-or-later.

  • Installing

    What you need, the container, TLS in front, and getting to a working sign-in.

  • Configuring

    Every environment variable — and the Stalwart-side settings a few features depend on.

  • Using ihasmail

    The parts that are not self-evident: filters, calendars, contacts, files, and the mail behaviours that differ from what you would guess.

Before you start

ihasmail requires Stalwart 0.16 or newer

Sign-in refuses anything older, by name. The last release that runs on 0.15 is tagged stalwart-0.15-support; if you need to move a live server from 0.15, stalwart-migrator does it in place without the parts that go wrong by hand.
