A reply opened in the format the settings ask for, whatever the message being answered was written in, and the per-draft switch was buried in the composer's ⋮ menu. Replying in plain text to a rich text message throws away the formatting; replying in rich text to a plain-text one overrides what the sender chose to write in. When the two disagree the composer now says so above the editor -- "This message is rich text", with a Switch button and a dismiss -- and the draft still opens in the format the settings ask for. Switching converts that draft only and leaves the setting alone; switching from the ⋮ menu answers the offer too. Forwards get it as well, where the formatting being passed on is somebody else's. What counts as rich text is hasHtmlAlternative(), which reads the body part's own type: `htmlBody` is derived (RFC 8621 4.1.4), so a plain-text message has one too and its presence proves nothing. The mock said otherwise -- it returned an empty `htmlBody` for a plain-text message, where Stalwart 0.16.21 returns the text/plain part in both lists. Both builders now answer as the server does, so the path this feature depends on is exercised in development rather than only against a real mailbox. Two new strings, translated in all nine catalogs; the buttons reuse the menu's existing "Switch to plain text" / "Switch to rich text". The count falling back to English stays at 16 in every language. Fixes #407

A working copy with an invented mailbox behind it — no sign-up, nothing real, nothing kept.
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.

Taken against the built-in mock with sample data. More, including the phone layout, on ihasmail.org.
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.
