AGPL source offer and name cleanup

Browse Source 
Every build writes the exact source it was built from, uncommitted work and
new files included, as source.tar.gz next to the app, named after that tree.
Docker builds, which have no git, pack the build context and name it by a
hash of its files. The sign-in page and Settings > About link to it instead of
a repository that can drift.

What users, operators and packagers see no longer names the upstream server:
- interface text, in all nine catalogues, with a token-session line for
  Security;
- server messages;
- the settings, now MAIL_SERVER_URL, MAIL_SERVERS_FILE, ADMIN_URL and
  MAIL_SERVER_FOLLOW_ADVERTISED_URLS, and mail-servers.example.json;
- the Tenants notice, which is gone;
- the README, CONTRIBUTING and SECURITY.

ihasmail's own FEATURES, KNOWN-ISSUES and ROADMAP stay with public ihasmail,
and INBUXA.md is folded into the README.

# ihasmail
The webmail of the INBUXA suite: mail, calendars, contacts, files and filters
in one app that works as well on a phone as on a desktop. It talks only JMAP to
the INBUXA mail server, and keeps nothing of its own: everything durable,
settings included, lives on the server, so the container is disposable.
**Immutable webmail for [Stalwart Mail Server](https://stalw.art).** 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
- **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**, stored on the mail server.
- **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 to an account whose role allows it.
Everything else is in INBUXA Admin.
- **Sign-in on the mail server's own page**, two-factor included. The webmail
never handles a password to sign someone in, and holds only sealed tokens.
- **Ten interface languages and twelve themes.**
The long version is [FEATURES.md](FEATURES.md) and
[ihasmail.org](https://ihasmail.org/#features).
## Configuration
## Requirements
| Variable | Meaning |
|---|---|
| `MAIL_SERVER_URL` | How this webmail reaches the mail server. |
| `APP_SECRET` | A long random secret for sealing sessions. Required in production. |
| `OAUTH_CLIENT_SECRET` | Turns on sign-in through the server's page. The secret of the confidential client the server registers for this webmail: on the server, the same value as `INBUXA_WEBMAIL_CLIENT_SECRET`. |
| `OAUTH_CLIENT_ID` | The client's id. Default `ihasmail-inbuxa`, which is what the server registers. |
| `PUBLIC_URL` | Where browsers reach the webmail, without `BASE_PATH`. Required with `OAUTH_CLIENT_SECRET`. The redirect URI, `PUBLIC_URL` + `BASE_PATH` + `/api/auth/callback`, must match the server's `INBUXA_WEBMAIL_URL` + `/api/auth/callback` exactly. |
| `MAIL_SERVERS_FILE` | Optional: several mail servers, picked by the account's domain. See `mail-servers.example.json`. |
| `ADMIN_URL` | Optional: where INBUXA Admin is, for the dashboard's link. |
| `APP_NAME` | What the webmail calls itself. Default `INBUXA`, shown as the INBUXA wordmark; any other name shows as text. |
**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](KNOWN-ISSUES.md).
`.env.example` lists the rest.
- **No Stalwart yet?** [ihasmail-oneshot](https://github.com/Coffey-Labs/ihasmail-oneshot) deploys a new Stalwart and ihasmail together on one host, in one command.
- **On Stalwart 0.15?** [stalwart-migrator](https://github.com/Coffey-Labs/stalwart-migrator) upgrades it in place, or stay on the [`stalwart-0.15-support`](https://github.com/Coffey-Labs/ihasmail/releases/tag/stalwart-0.15-support) release.
On the mail server, set `INBUXA_WEBMAIL_URL` to the webmail's address (with
`BASE_PATH`, if any) and `INBUXA_WEBMAIL_CLIENT_SECRET` to the shared secret.
The server registers the client on start and allows the webmail's origin for
cross-origin requests.
With one mail server, the sign-in page asks for no address, only whether this
is the person's own device. The server's page asks for the rest. With several,
the address comes first, since its domain picks the server.
A password change revokes the server's tokens, so it signs the person out
everywhere, this session included.
## Quick start (Docker)
```bash
cp .env.example .env
# edit: STALWART_URL=https://mail.example.com and APP_SECRET=$(openssl rand -base64 48)
# edit: MAIL_SERVER_URL, APP_SECRET, and for server sign-in OAUTH_CLIENT_SECRET and PUBLIC_URL
docker compose up --build -d
# → http://localhost:8080 — put a reverse proxy in front for TLS
# → 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`.
## Source code
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](https://docs.ihasmail.org/install/) and
[Configuring](https://docs.ihasmail.org/configure/).
Every build carries its own source. The sign-in page and Settings › About
link to `source.tar.gz`, the exact tree the running version was built from,
uncommitted work included. It's written next to the app at build time and
named after that tree.
## Development
```bash
npm install
npm run dev:mock # built-in mock Stalwart ([email protected] / demo)
npm run dev:mock # the built-in mock mail server ([email protected] / demo)
npm test
```
The mock also answers OAuth. Start it and the webmail with
`OAUTH_CLIENT_SECRET=mock-oauth-secret` and a `PUBLIC_URL`, and its sign-in
page approves the demo user at once.
Architecture, the mock's switches and how versions are numbered are in
[CONTRIBUTING.md](CONTRIBUTING.md#development-setup).

The INBUXA webmail is built on [ihasmail](https://github.com/Coffey-Labs/ihasmail),
Coffey Labs' own webmail, which stays an independent product. The public
repository is the remote `ihasmail`, fetch-only, and its `main` is merged in to
keep up. Nothing here is pushed there.
