New-install privacy defaults, and expired bans purged daily
Personal-data catalog spec, defaults D2, D3, D4, D6 and D7 (settled
2026-09-28, new installs only):

- D2: automatic IP bans expire after 30 days instead of never; D3:
  spam training samples, whole messages, are kept 90 days instead of
  180; D4: Pyzor, which sends a digest of each message's text to a
  public server, is off; D6: delivery history is kept 14 days instead
  of 30. Written on the first boot of a new install only -- one with no
  roles yet, the same test the built-in roles use -- by reading each
  singleton, setting these fields and writing it back whole. A server
  with roles keeps its settings, saved or default.
- D7: a webhook created from now on starts with the include policy and
  no events, so it sends nothing until events are chosen (Rust default
  and schema default, marked). The registry stores every field, so
  existing webhooks keep their policy.
- Expired bans are also removed by the daily data clean-up. They
  already stopped blocking and were deleted when settings next loaded;
  a server that seldom reloads kept them.

D1 (log retention) and D5 (the hashed-address blocklist off) are held,
and the spec says why: x:TracerLog is stored inside x:Bootstrap with a
field after it, so adding one changes that object's stored format; and
the spam-rules loader D5 touches is being reworked by the v0.16.24
import. The spec also corrects finding 3: expired bans were deleted on
settings load; bans were permanent only because no period is set.

Tested: unit tests for the new-install values and that everything else
in each singleton stays; the system suite, whose security test now
purges an expired ban and checks its record is gone; the telemetry
test; common's unit tests; fork checks.

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. 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, 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 aren't read: the server stops at startup and names each one to rename. 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.
