The server fetched upstream's latest published rules from GitHub at run
time: a version nobody here tested, code-like expressions from an account
we don't control, and the upstream name as a default in the admin form.
The published rules of spam-filter v3.0.2 are now embedded
(resources/spam-filter/, MIT, in THIRD-PARTY.md) and used whenever no other
source is configured. An empty setting and upstream's old default both mean
the bundled rules, so existing installs switch without a settings change;
the URL stays an operator override (https:// or file://). The schema default
is dropped and its description says what empty means, and the strip's
rename pass does the same to each import.
Rules load on first boot as before, and again whenever the bundled version
differs from the last one loaded, which only adds missing rules and tags.
That brings the AI classifier's LLM_* scores to installs that predate them:
production has none today.
upstream-watch now also opens an issue when spam-filter publishes a newer
release; resources/spam-filter/README.md says how to take it.
The antispam test now runs on the bundled rules, the path production
takes; SPAM_RULES_URL tests another set. Unit tests cover the URL handling
and that the bundled rules parse and score the AI tags as the AI spec says.
The server sets a deferred recipient's next retry from its clock when the
attempt defers, in whole seconds. The test subtracted its own clock taken
when the loop next saw the message, after saving and reporting, so
whenever that lag crossed a second boundary the 2 s retry measured 1 s
and the test failed. Under load, after the other SMTP tests, that was
most runs.
It now measures from when the test started the attempt, which the
server's deferral can only follow, by under a second: each retry is its
interval or one more. Each position is still checked against its own
interval, so a wrong schedule still fails.
It listens on HTTP 19048, as the dkim2 DSN and report tests do. Those are
marked serial, this wasn't, so when the SMTP tests ran together (as
upstream's CI runs them) it could start beside them and requests reached
whichever server had the port: missing JMAP creates here, and 'You must
authenticate first' in dkim2_dsn_is_signed.
It failed everywhere but upstream's machines, for two reasons:
- The spam rules, which carry every score, came from a path on an
upstream developer's own disk. Without SPAM_RULES_URL none loaded, every
score was 0.00 and the combined case came out ham instead of spam at
13.70. The published rules of spam-filter v3.0.2 are now pinned beside
the test cases (Apache-2.0 or MIT, taken as MIT; in THIRD-PARTY.md).
SPAM_RULES_URL still overrides.
- The first combined case expects a Pyzor hit, and its digest (that of an
empty body) wasn't among the three the test mode answers, so it went to
a public Pyzor server: it failed offline and would drift with that
server's counts. Test mode now answers every digest from a fixed table,
with the empty body's added, and never reaches the network.
The test passes online and offline, alone and with the rest of the SMTP
tests. queue_retry, unrelated, still fails when it runs after the others
in one process, though it passes alone every time.
Five conflicts, resolved:
- crates/common/src/auth/authentication.rs: upstream's get_directory_for_token
and JwtClaims replace extract_jwt_domain; the per-domain directory code
(DIR-1, DIR-5 to DIR-7) is kept, and the token lookup routes through it.
The release's one new Enterprise snippet was the body of
get_directory_for_issuer, which stays returning None: a token naming no
address gets the server default, as DIR-2 specifies and as v0.16.22 did.
- crates/common/src/manager/application.rs: upstream's rewrite of the tests,
with the temp directory names renamed again, and the 5(a) notice the
name-purge change should have added.
- crates/common/src/network/mta.rs: both sides' imports.
- crates/main/Cargo.toml: the AGPL-only license kept, version 0.16.23.
- Cargo.lock: upstream's, with the fork's crates added by Cargo.
The AGPL asks a modified version to carry prominent notices saying it was
modified, and giving a date. Publishing the source is the conveyance that
asks for it, so it wants doing before the repository is public rather than
at the release.
Every upstream file the fork changed now says so in its header, beneath the
notice it came with: 164 files, found by diffing against the upstream
snapshot branch rather than by guessing, so the list is what actually
differs. Files the fork wrote itself already carry their own copyright and
need nothing. Upstream's notices are untouched, which its licence requires
and which was already true.
The README says the same thing in prose, since the obligation is on the
work as a whole and not only its Rust files.
Builds unchanged: the server and the test binary both compile.
The classifier sends only the subject and text, between unforgeable markers
after the operator's prompt, to an OpenAI-compatible endpoint the operator
configured; nothing is preset. Its answer maps to an LLM_ tag whose score is
clamped (+5.0, -1.0 by default) and can never discard or reject on its own;
X-Spam-LLM is sanitized, encoded and folded, and a planted one is removed.
Failures, timeouts past the ceiling, a full slot or a paused model leave
mail flowing untagged. llm_prompt answers trusted scripts, and accounts
holding interactAi within an hourly limit. Redirects aren't followed and no
content or secret is logged. The limits live in inbuxa:AiLimits.
Acceptance tests 1 and 3 to 21; test 2 as the re-enabled shared llm case,
whose setup no longer waits on a rules file from a developer's own path;
test 22 written as the ignored ai_compat.
- The recovery administrator (INBUXA_RECOVERY_ADMIN, or STALWART_RECOVERY_ADMIN)
is honored only in bootstrap and recovery mode. On a configured server it's
ignored with a startup warning. Before, it was a standing full-admin login
for as long as the variable stayed set.
- The Enterprise upsell error is replaced by "This feature isn't available in
INBUXA yet" for the features still to be rebuilt.
- Workspace warnings: 25 to 0. cargo fix removed the unused imports. The
seven places where Enterprise code used to plug in keep their parameters,
each with an inbuxa: comment naming the rebuild that uses it again. The
antispam test's mock-server imports are back behind pending-rebuild.
