The picker offers English plus nine translations. I wrote it up as nine in total with eight unread, which is off by one in the direction that undercounts the work and, worse, misstates how many catalogues are waiting for a speaker to read them. Nine of the ten are machine-made and unread — all of them, not all but one — so the sentence that matters reads more sharply than the wrong version did, not less.

# ihasmail
|
||
|
||
**Immutable webmail for [Stalwart Mail Server](https://stalw.art) — a container
|
||
with nothing to persist, and a Gmail-class client on top of it.**
|
||
|
||
Mail, calendars, contacts, files and filters in a responsive single-page app
|
||
that works equally well on a desktop monitor and a phone. It talks only JMAP
|
||
(plus Stalwart's blob/upload/EventSource endpoints) — no IMAP, no SMTP, no
|
||
database, and with `IMMUTABLE=1` no writable filesystem either. Everything
|
||
durable belongs to Stalwart; the container is disposable.

|
||
## What's in it
|
||
|
||
- **Mail** — three-pane Gmail-style layout, conversation view, virtualised list, labels, undo, Gmail search operators and keyboard shortcuts, Sieve rules from a message's context menu, sanitised HTML with remote images blocked, read receipts, invitations and RSVP, multi-composer rich-text editing with signatures, scheduled send and undo send
|
||
- **Calendar** — JMAP Calendars / JSCalendar: month/week/day/agenda, recurrence, attendees and free-busy, colour categories
|
||
- **Contacts** — JMAP Contacts / JSContact: address books, groups, full editor, vCard import/export
|
||
- **Files** — JMAP FileNode: browse, upload, download, rename, move, delete
|
||
- **Settings that follow the account**, not the browser — kept in a `settings.json` in the account's own JMAP Files, so ihasmail itself stays stateless
|
||
- **Runs read-only** — one optional write path, and with it switched off the container needs no volume and no writable root. `IMMUTABLE=1` is checked at startup rather than trusted, so a half-applied switch refuses to boot instead of failing quietly. See [Running immutably](#running-immutably)
|
||
- **Nine new interface languages** — German, Spanish, French, Dutch, Portuguese (Brazil), Russian, Ukrainian, Simplified Chinese and Japanese, alongside English and separate from the date-and-time locale. Every one is marked **Beta**: they were made by AI and no native speaker has read them yet, which Settings says plainly, with a link for reporting anything wrong
|
||
- **On a phone** — swipe a message to archive or delete it (either direction, your choice), hold one to select it, hold a folder for its menu, pull the list to refresh, swipe back from a conversation
|
||
- **Platform** — installable PWA, Web Push with ihasmail closed, `mailto:` handler, no credentials in the browser, strict CSP, SSRF-safe image proxy
|
||
|
||
The long version is on [ihasmail.org](https://ihasmail.org/#features); how to
|
||
drive each one is in [Using ihasmail](https://docs.ihasmail.org/using/).
|
||
|
||
## Requires Stalwart 0.16 or newer
|
||
|
||
Sign-in refuses anything older, by name. 0.16 replaced the REST management API
|
||
with JMAP registry objects, changed the shape of `FileNode`, split its rights up
|
||
and moved configuration into the store; supporting both generations meant a
|
||
wrong guess had somewhere to fall back to, so it failed *quietly* — and that
|
||
reached production. With one supported generation a wrong guess is a loud error
|
||
on the first call.
|
||
|
||
- Still on 0.15? The last release that runs on it is tagged [`stalwart-0.15-support`](https://github.com/Coffey-Labs/ihasmail/releases/tag/stalwart-0.15-support).
|
||
- Upgrading? [stalwart-migrator](https://github.com/Coffey-Labs/stalwart-migrator) does it in place, checkpointing every phase and validating afterwards. The live instance moved 0.15.5 → 0.16.19 with eight seconds of downtime and nothing lost.
|
||
|
||
## Quick start (Docker)
|
||
|
||
```bash
|
||
cp .env.example .env
|
||
# edit: STALWART_URL=https://mail.example.com and APP_SECRET=$(openssl rand -base64 48)
|
||
docker compose up --build -d
|
||
# → http://localhost:8080 (put Caddy/nginx in front for TLS; see Caddyfile.example / nginx.example.conf)
|
||
```
|
||
|
||
Users sign in with their Stalwart mailbox credentials. **An account with
|
||
two-factor authentication needs an app password**, created in Stalwart's own
|
||
settings — Stalwart accepts a TOTP code only through an OAuth flow and offers no
|
||
password grant, so no client holding a username and password can exchange them
|
||
plus a code for a token.

||
|
||

|
||
|
||
### Running immutably
|
||
|
||
The server writes to exactly one path, the optional `SESSION_FILE`. Clear it
|
||
and there is nothing left to write, so the container can run with no writable
|
||
filesystem at all:
|
||
|
||
```bash
|
||
docker run --read-only --tmpfs /tmp -e IMMUTABLE=1 -e SESSION_FILE= ...
|
||
```
|
||
|
||
`IMMUTABLE=1` is an assertion the server checks at startup rather than a switch
|
||
that changes what it does: it refuses to start if `SESSION_FILE` is still set,
|
||
or if the filesystem it is installed on turns out to be writable after all.
|
||
Without it the same misconfiguration is silent — sessions are held in memory
|
||
and persisting them is best-effort, so a read-only `/data` costs one warning at
|
||
the first sign-in and nothing else until the instance is replaced and everyone
|
||
is signed out.
|
||
|
||
That sign-out is the standing cost of this mode today, since sessions have
|
||
nowhere to live across a restart. Removing it means moving the session upstream
|
||
into a token Stalwart itself issues and can revoke, which is what the OAuth work
|
||
in [ROADMAP.md](ROADMAP.md) is for.
|
||
|
||
## Architecture
|
||
|
||
```
|
||
browser ──(same-origin /api/*)──► ihasmail server (Node + Hono) ──(JMAP over HTTPS)──► Stalwart
|
||
React SPA • session cookie ⇄ Basic auth
|
||
JMAP client + stores • /api/jmap, /api/blob, /api/upload, /api/events (SSE), /api/image
|
||
```
|
||
|
||
- `web/` — Vite + React 19 + TypeScript SPA. `src/jmap` (client, push, types), `src/store` (zustand: session, mail, compose, contacts, calendar, files, sieve, settings), `src/views`, `src/lib` (sanitiser, search parser, Sieve codec, locale-aware dates, vCard, …).
|
||
- `server/` — Node/Hono backend: authenticates against Stalwart's JMAP session endpoint, seals the credentials with a key derived from the cookie secret, proxies JMAP/blob/SSE, serves the SPA under a strict CSP. `src/mock/` is an in-memory fake Stalwart for development and demos.
|
||
|
||
Capabilities used: `core`, `mail`, `submission`, `vacationresponse`, `sieve`,
|
||
`contacts`(+`parse`), `calendars`(+`parse`), `principals`(+`availability`),
|
||
`quota`, `blob`, `filenode`, EventSource push, plus Stalwart's own
|
||
`urn:stalwart:jmap` (read-only). Features degrade gracefully when one is
|
||
missing.
|
||
|
||
## Development
|
||
|
||
Requirements: Node ≥ 20.10 (22 recommended), npm ≥ 10.
|
||
|
||
```bash
|
||
npm install
|
||
|
||
npm run dev # real Stalwart (STALWART_URL in .env) — server :8080, Vite :5173
|
||
npm run dev:mock # built-in mock Stalwart ([email protected] / demo), mock on :8788
|
||
npm run dev:mock:no-future-release # mock that advertises FUTURERELEASE and drops every hold
|
||
|
||
npm run typecheck # tsc for both packages
|
||
npm test # vitest (web) + node:test (server)
|
||
npm run build # web/dist + server/dist
|
||
npm start # serve the production build
|
||
```
|
||
|
||
Open http://localhost:5173 in dev, or http://localhost:8080 for the production
|
||
build. Running it for real is covered in
|
||
[Installing](https://docs.ihasmail.org/install/) and
|
||
[Configuring](https://docs.ihasmail.org/configure/).
|
||
|
||
### The mock
|
||
|
||
An in-memory fake Stalwart 0.16 — enough JMAP to develop and demo against
|
||
without a real mailbox. It reproduces the things a naive fake would get wrong,
|
||
because each cost a live debugging session: `urn:stalwart:jmap` advertised
|
||
**per-account** rather than session-level, identity signatures capped at 2047
|
||
**bytes**, and `CalendarEvent/set` speaking Stalwart's vocabulary rather than
|
||
RFC 8984's. Two switches: `MOCK_NO_FUTURE_RELEASE=1` advertises FUTURERELEASE
|
||
and then drops every hold; `MOCK_NO_REGISTRY=1` omits the Stalwart capability so
|
||
the sign-in refusal can be tested.
|
||
|
||
### Version numbers
|
||
|
||
`ihasmail v2026.8.30+pr129` — the date of the commit this was built from, and
|
||
the pull request that commit arrived through. A commit that did not arrive
|
||
through one carries its short SHA instead: `2026.8.30+g1fa6578`. It all comes
|
||
from git at build time; nothing writes a version into the tree, and
|
||
`package.json` sits at `0.0.0` because it is no longer the source of anything.
|
||
|
||
The date is the commit's own rather than today's, so rebuilding an old commit
|
||
gives the version it had the first time.
|
||
|
||
```bash
|
||
node scripts/version.mjs # the version for the current checkout
|
||
docker build --build-arg IHASMAIL_VERSION="$(node scripts/version.mjs)" -t ihasmail:2026.8.30 .
|
||
```
|
||
|
||
`.dockerignore` excludes `.git` deliberately, so an image build cannot work this
|
||
out for itself — pass it in. Left out, the build reports `0.0.0`, which is meant
|
||
to look wrong: a version with no `+pr` or `+g` means whoever built the image did
|
||
not pass one.
|
||
|
||
The version says nothing about Stalwart, deliberately. It used to: `2.16.x` had
|
||
`16` for the 0.16 generation it targeted, which leaves nowhere to go once
|
||
Stalwart reaches 1.0 — `2.1` sorts *below* the `2.16` already deployed, so every
|
||
image and About screen would read as a downgrade. Which Stalwart a build needs is
|
||
stated where it can be precise, in the badge at the top of this file and in
|
||
[KNOWN-ISSUES.md](KNOWN-ISSUES.md), rather than compressed into one digit.
|
||
|
||
The pull request lives after the `+`, as build metadata, because it is
|
||
provenance rather than a rank: at the rate they merge here it climbs without
|
||
bound and says nothing about how new a build is. Everything after the `+` is
|
||
ignored when versions are compared, which is the right reading — two builds from
|
||
the same day differ in where they came from, not in age. Nothing here depends on
|
||
that comparison: images are pruned oldest-first by creation time, and a rollback
|
||
names a git ref.
|
||
|
||
### Deploying
|
||
|
||
[`deploy.example.sh`](deploy.example.sh) is a single-host Docker deploy: it
|
||
fetches, refuses anything held back by `.deploy-hold`, shows what is about to be
|
||
introduced and asks, rebuilds with the right version baked in, replaces the
|
||
container, waits for healthy, then prunes all but the newest
|
||
`IHASMAIL_KEEP_VERSIONS` images — never the one actually running.
|
||
|
||
```bash
|
||
./deploy.sh # origin/main, asks before shipping new commits
|
||
./deploy.sh --dry-run # run the guards and stop
|
||
./deploy.sh v2026.8.30 --yes # a named ref, no prompt (there is no tty over ssh)
|
||
```
|
||
|
||
`--yes` does not override a hold; clearing one means deleting its line.
