jcoffey-dev 3158277b04 Per-domain directories: changes apply on the next request, and one broken directory doesn't block reloads (DIR-17, DIR-21)
A write to x:Directory or Authentication reloads the directories at once,
here and across the cluster. A directory that fails to open is logged as
a warning against its id and becomes unavailable; before, it was a build
error, and any build error stopped every later reload from applying.

per_domain_directory_tests covers acceptance tests 1, 3, 4, 6, 7, 9, 11,
15 and 19 over SQL directories on SQLite files: each domain against its
own directory and the default, no fallback to internal passwords, a
directory answering for another directory's domain, aliases and groups
dropped, recipients through the directory and a 4xx while it's down, app
passwords while it's down, password changes refused and then allowed
after a move to the internal directory, linked directories, tenant
foreign keys, and changes taking effect without a reload.

inbuxa

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 (not up yet).

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.

Status: in development, not released. The fork builds, passes its unit tests, and runs as a working mail server. The Enterprise features are being specified and haven't been rebuilt yet. Don't run it in production.

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, and docs/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.
