Every minute the node that calculates metrics evaluates each enabled
x:Alert, read from the registry, with metric('name') or the underscore
name. An alert fires when its condition turns true: it emits
telemetry.alert-event with the rendered message, and queues one email per
recipient through the outbound queue, placeholders filled and
Auto-Submitted set. An alert naming an unknown metric is refused on save.
The shared alerts suite runs; every telemetry suite is un-gated.
GET /api/token/tracing and /api/token/metrics issue a 60-second token for
holders of liveTracing or liveMetrics outside a tenant. /api/live/tracing
streams event: trace frames of x:TraceEvents, never raw I/O, filtered by
text or by key, with a ping while idle; /api/live/metrics streams event:
metrics frames of current totals every interval. At most eight streams run
per node, each for 30 minutes. Upstream's documented paths are aliases.
A lossy collector subscriber keeps each inbound SMTP session that reached
MAIL FROM and each delivery attempt, info level and above and never raw
I/O, at most 1,000 events with strings cut at 4 KiB, and writes it when
the span closes as an x:Trace under the telemetry key class, scheduling
its indexing. The index task builds a document of event types, queue ids
and keywords when indexTelemetry is on. x:Trace/get derives timestamp,
from, to and size; /query filters by opening event, text, queueId and
time; /set destroys only. The data purge honours holdTracesFor. The shared
tracing and webhook suites run.
Every node writes a sample per metric on metricsCollectionInterval:
counters as the increase since its last sample, gauges always, histograms
as totals when changed. Samples are x:Metric in the registry's encoding
under the telemetry key class, ids time-ordered. x:Metric/get and /query
read them with metric and timestamp filters and full paging, hide what's
past holdMetricsFor, and the data purge deletes it. The is_enterprise
split is gone, so every gauge and histogram is collected and exported, and
queue.count is set from the queue itself. The shared metrics suite runs.
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.
Logos resolve domain, then tenant, then server-wide, then the built-in, with
subdomains finding their domain. GET /logo serves a data-URL image, redirects
to a URL logo without fetching it, sandboxes SVG, and answers 404 when no
custom logo applies. Emails embed the first PNG, JPEG or GIF logo. Logo and
template writes are checked; stored templates are read at send time, always
escaped, and fall back to the built-in with a build warning when they don't
parse. The RSVP page is served byte for byte with a CSP and no-referrer. The
sign-in and RSVP pages load the logo through an image element. MT-22's
session logo follows the chain to the server-wide logo.
Acceptance tests 1 to 17; test 18 written as the ignored branding_compat.
With archiveDeletedAccountsFor set, a destroyed account's record is kept in
the fork subspace with its id, its DestroyAccount task is due at the end of
the period, and its shares are suspended both ways. Its addresses can't be
taken by new accounts, aliases, lists or masks. inbuxa:DeletedAccount/get
lists kept accounts to server and tenant administrators; /set restores one
with a new password (same id, task cancelled, shares reinstated) or destroys
it now. The destroy task also clears undelete's own records.
Acceptance test 14; test 16 written as the ignored undelete_compat.
Every way of deleting mail for good (JMAP, IMAP expunge, POP3, Trash
emptying, mailbox removal) notes the message's mailboxes and keywords while
archiving is on, fixing its deadline then; when its data is finally removed
it becomes an x:ArchivedItem record, written as upstream writes them, with
its copy held until the deadline. Retention is read at deletion time, so a
change applies at once. Restore puts a message back in the mailboxes it was
in (Trash only if that was all), with its keywords, and removes the record;
over quota it stays archived. x:ArchivedItem/get returns status and
accountId; query filters on type, archivedAt and text; set requests a
restore once or destroys; /changes is a fork addition. Expired items go in
the data purge. The shared account-access rule moves to jmap::inbuxa::access.
system_tests now calls undelete::test, and the archiving gate is gone.
Found by running system_tests, which masked email no longer stops:
- rcpt_resolve rewrites a live mask to its owner's address, so
Delivered-To names the account; delivery recognizes the mask from the
original recipient when it belongs to that account.
- x:MaskedEmail/set create responses carry the server-set email.
- x:MaskedEmail/query returns every mask to a server-level impersonate
holder, and filters on accountId.
- The refusal for an unlinked emailDomain uses upstream's wording.
- The shared delivery test checks the fork's address format (ME-13).
- The masked email test's tenant domain uses manual DKIM, so its cleanup
leaves nothing behind.
tests/src/system/masked_email.rs runs from system_tests and alone as
masked_email_tests. Fastmail's MaskedEmail/set updates from the stored
object, so the registry's revision check holds.
Advertised as https://www.fastmail.com/dev/maskedemail in the session and on
every account that may hold masks. Masks created through it start pending
unless the create sets a state; pending can't be set again once left; state
and the other mutable fields map onto the same records the x: API uses.
The fork's per-account change log answers /changes, collapsing a mask
created and destroyed in the window. /changes on a registry type needs that
type's get permission.
x:MaskedEmail is no longer refused as unbuilt. Creates generate the address
on an allowed domain and check the prefix, maxMaskedAddresses and the create
rate; updates keep server-set fields; enabled reads and writes map to the
shared state; query filters on enabled, forDomain and text; a tenant
administrator reaches its tenant's accounts' masks.
JMAP shareWith refuses a grantee outside the owner's tenant, or missing, with
invalidForeignKey naming the account. WebDAV ACL answers AllowedPrincipal and
IMAP SETACL answers as for an unknown account.
The session's own account carries urn:inbuxa:jmap with logo: its domain's
logo, else its tenant's, as stored. The session lists urn:inbuxa:jmap as a
server capability too.
Inside a tenant, server-level object types are forbidden and x:Tenant reads
return only the caller's own tenant, which it can't change. Registry writes
refuse links across tenant boundaries in both directions, give a new
principal its domain's tenant, move a domain's principals and DKIM keys with
it into a tenant, refuse moves out of a tenant while its people remain, and
refuse creates past a tenant's count limits with overQuota and
limit.tenant-quota.
- 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.
- crates/main: package and [[bin]] renamed to inbuxa; homepage inbuxa.org;
license AGPL-3.0-only (upstream is dual; the fork takes the AGPL).
- types::branding::env_var reads INBUXA_<name>, falling back to
STALWART_<name> with a warning, for all nine server settings.
STALWART_APP_ and STALWART_SPAM_* storage keys are unchanged.
- New-install default paths /var/lib/inbuxa and /var/log/inbuxa.
- Dockerfiles, systemd unit, launchd plist and AppArmor profile renamed.
- Upstream's .github moved to .github-upstream so none of it runs.
- install.sh stubbed: upstream's would install Stalwart.
- Two missed brand strings: the SMTP Received header and the utils user agent.
