server/src/mock/index.ts was 1,545 lines, the largest file in the repo.
It had carried `/* ---------- data ---------- */` style markers for a
while, so the seams were already drawn; this turns six of them into
files.
mock/config.ts 51 env-derived constants, `account`, `state`
mock/data.ts 410 fixtures and the builders that make them
mock/engine.ts 442 the generic JMAP machinery -- get/set, filters,
patches, refs, limits, recurrence plumbing
mock/handlers.ts 455 the `Method/name` dispatch table
mock/events.ts 26 SSE fan-out and the Email/changes ring buffer
mock/auth.ts 11 checkOtp
mock/index.ts 195 HTTP routing, the session document, listen
TWO THINGS THAT COULD NOT JUST MOVE:
`counter` and `vacation` were module-level `let`s written from both the
fixture builders and the handlers. An ES module can export a `let` and
importers see it update, but they cannot assign to it, so both became
containers: `seq.counter` and `vacationBox.current`. Seven call sites.
`recordEmailChange`, `broadcast`, `sseClients` and `checkOtp` lived in
the HTTP section, but the handlers call them -- and index.ts imports the
handlers. Leaving them there is a cycle, so they became events.ts and
auth.ts rather than being dragged into data.ts, which is fixtures.
`account` is still exported from index.ts, because account.test.ts and
login-guard.test.ts reach for `mock.account` and `mock.server`.
Verified by running it, not only by compiling it: `npm run mock` boots
and listens, `/.well-known/jmap` returns a session, and a POST to
`/jmap/` answers Mailbox/get with the nine seeded folders and
Email/query with the seeded messages.

ihasmail
Immutable webmail for Stalwart Mail Server. Mail, calendars, contacts, files and filters in one app that works as well on a phone as on a desktop — and a container with nothing to persist.
ihasmail talks only JMAP to Stalwart. There is no database, no IMAP or SMTP,
and with IMMUTABLE=1 no writable filesystem either: everything durable,
settings included, belongs to Stalwart, so the container is disposable.

What's in it
- Mail — conversations, labels, search operators, keyboard shortcuts, scheduled and undo send, invitations and RSVP, filters made from a message
- Calendar — month, week, day and agenda views, recurrence, attendees and free-busy
- Contacts — address books, groups, vCard import and export
- Files — browse, upload, move, share
- Signature checking — S/MIME signed mail verified as you read it
- Settings that follow the account, kept in the account's own storage on Stalwart
- On a phone — swipe to archive or delete, pull to refresh, hold to select
- Administration — a dashboard, accounts, groups, mailing lists, roles, tenants and domains, each shown only when the Stalwart role allows it
- Ten interface languages and twelve themes — the nine translations are marked Beta until a native speaker has read them
- Platform — installable PWA, Web Push,
mailto:handler, no credentials in the browser, strict CSP
The long version is FEATURES.md and ihasmail.org.
Requirements
Stalwart 0.16 or newer — sign-in refuses anything older, by name. Tested against 0.16.22; what changed in each release is in KNOWN-ISSUES.md.
- No Stalwart yet? ihasmail-oneshot deploys a new Stalwart and ihasmail together on one host, in one command.
- On Stalwart 0.15? stalwart-migrator upgrades it in place, or stay on the
stalwart-0.15-supportrelease.
Quick start (Docker)
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 a reverse proxy in front for TLS
Or pull the published image, ghcr.io/coffey-labs/ihasmail. Releases are
weekly, so it is usually a few days behind main.
People sign in with their Stalwart mailbox credentials. An account with two-factor authentication needs an app password, created in Stalwart's own settings.
Everything else — TLS, running immutably, several Stalwart servers, settings the installation decides, every environment variable — is in Installing and Configuring.
Development
npm install
npm run dev:mock # built-in mock Stalwart ([email protected] / demo)
npm test
Architecture, the mock's switches and how versions are numbered are in CONTRIBUTING.md.
