Turning legacy mail protocols off or back on raises security.legacy-protocols-changed (id 643, info level, also in the packaged schema), with the scope (policy = server), the new value, who made the change (accountId), whether listeners closed or reopened (details), which ones (listenerId), and -- only when a listener could not be put back -- which and why (reason). It is raised in Server::set_protocol_policy rather than by the JMAP method, so whatever turns the switch is reported. A /set that changes nothing -- the switch already where it was asked to be, nothing to close or reopen -- is not a change and raises nothing. The event is never an error, but jmap's exhaustive map from security events to HTTP errors has to name it; it joins the other two that can't occur there. rustfmt now also wraps LP-6's two over-long lines in enums_impl.rs, which it flagged along with this change's. tests/e2e/legacy_protocols.py now gives the server a stdout tracer and reads events from the container's log: turning the switch off is exactly one event naming the scope, value, author and listeners closed; setting it off again raises none; turning it on is one event naming the listeners reopened. It also proves LP-6's side: seven refused submission sign-ins are seven auth.legacy-protocol-refused events, and there is no auth.failed or auth.too-many-attempts among them. All checks pass.
A complete mail and collaboration server, every feature included, under the AGPL
INBUXA is a mail and collaboration server: JMAP, IMAP, POP3, SMTP, CalDAV, CardDAV and WebDAV, in one Rust binary, with ihasmail as its web front end. It is a fork of Stalwart. Project site: inbuxa.org. Documentation: docs.inbuxa.org.
Stalwart ships some features only in a paid Enterprise Edition: multi-tenancy, masked email, undelete and others. INBUXA ships everything to everybody under the AGPL-3.0, rebuilding those features independently and without using any of Stalwart's Enterprise code.
What's different from Stalwart
- Every feature, one edition. No license key, no edition checks, no
upsell. See
docs/spec/SPEC.md§4 for the features being rebuilt, anddocs/spec/features/for each one's specification. - Webmail and administration by ihasmail, as a separate service that can run beside the server or elsewhere. Stalwart's own web interface is removed, so there's no web front end on the mail host.
- Clean-room rebuilds. Enterprise-only code is stripped from every
upstream release before it's imported. The rebuilt features are written
from specifications that use only public sources (
docs/spec/SPEC.md§3).
How the fork is kept
Upstream releases arrive as stripped snapshots, never with upstream's git
history, which contains Enterprise code. tools/fork/strip.py builds each
snapshot on top of upstream's own ossify.py, then verifies it independently.
The report for every import is in docs/fork/strip-reports/. See
docs/spec/SPEC.md §2.
Building
cargo build --release -p inbuxa # the binary is target/release/inbuxa
docker build -t inbuxa . # or the container image
Settings are read from INBUXA_* environment variables. An existing Stalwart
install's STALWART_* variables still work, with a warning to rename them.
New installs keep their data in /var/lib/inbuxa and logs in
/var/log/inbuxa. Existing installs keep the paths their configuration
already names, so none of their data moves.
