jcoffey-dev is traveling from Thursday 1 October through Sunday 4 October. Issues and pull requests are welcome, and will get an answer after that. Thanks for your patience.
Phase 2 of the journaling spec.
- A copy of each message is taken in MessageWrapper::queue, after DLP and
transport rules, for every enabled journal that takes it (direction and
scope: everyone, or accounts, groups, domains, tenants). If the copy
can't be taken the message isn't queued (temporary failure).
- The journal report: the envelope one field a line (sender, To, Cc, Bcc
from the envelope, list members from their ORCPT, direction, held for
review), then the queued message byte for byte as message/rfc822.
- The built-in journal under J in the inbuxa subspace: one chain per node
whose links name each entry by SHA-256, so entries can expire out of
chain order; purge leaves a marker, and verify catches an entry changed
or removed early and a report that doesn't match.
- Retention per journal (30 to 3650 days); an entry keeps what it was
written with. The daily maintenance purges what's due, keeping entries
whose people a legal hold covers (deleted accounts a hold keeps too),
and records the counts in the audit log.
- inbuxa:Journal get/set, audited by the request layer. Permissions
680-683: administrators see and change journals; the Compliance Officer
sees, searches and exports. Whoever changes journals may grant search and
export without holding them, so officers can still be appointed.
- Catalog entries (inbuxa:Journal, source "journal"); spec as-built notes.
tests/src/system/journal.rs: validation, internal mail with a Bcc,
outgoing into two journals, incoming over LMTP, the report and its
original, tamper and early removal caught, hold-aware purge, retention
changes leave entries alone, disabled and removed journals take nothing.
The hold action now holds (dlp-and-mail-flow-rules spec, §2.6), where
until now it blocked.
- At DATA a hold decision queues the message with its release a century
off (the queue's future-release mechanism, so the stored format is
unchanged and an older node just never sends it), transport rules
still applied, and replies 250 Held for review. A review record under
R/h + queue id keeps the sender, recipients, subject, size, rules and
detector counts. The sender is told when the rule asks.
- smtp/queue/held.rs: release (each recipient due now, its next notice
as far off as it was, its lifetime counted from the release), reject
(removed from the queue, the sender told, with the reviewer's note),
and expiry: the daily clean-up rejects what nobody reviewed in 7 days,
recorded as the server's doing.
- inbuxa:HeldMessage get/set: the review queue, sysDlpReviewGet to list
and read (preview, 64 KB of text, only when asked for and recorded as
blobAccess), sysDlpReviewUpdate to release or reject, a reason
required and audited by the request layer; no create or destroy;
server-level only.
- Guards: Emails > Queue refuses to change or delete held mail; the
sender can't unsend it.
- Privacy catalog entry for inbuxa:HeldMessage; spec §2.6 as built.
Tests: mail_rules_tests gains the whole flow (held and listed with
counts, sender notified and nothing delivered, queue and unsend
refused, preview recorded, reject needs a reason and tells the sender
the note, release delivers, expiry returns it, decisions audited with
reasons). smtp inbound, system_tests (after one BlobNotFound in
antispam, the known flake, then clean), features and common unit tests.
Personal-data catalog spec, §6 (Phase 3c).
inbuxa:DataInventory/get evaluates the catalog against the server's
live settings and says what this server holds: for each source and each
object that can hold personal data, its categories and whose data it
is, whether it is collected here at all, what bounds its retention (the
live value of the setting that does, or unbounded), whether it leaves
the host and to which endpoints, and a summary. Every host that
receives something is listed once as a candidate processor with what it
receives. Inside a tenant it answers with the tenant's slice and none
of the server's processors. Read-only, with sysComplianceGet.
inbuxa:InventorySnapshot/get is the history: a dated copy of the
evaluated inventory, recorded when it changes -- after a registry write
to an object the inventory reads, after inbuxa's log, audit or AI
settings change, and on the daily clean-up -- and kept as long as the
audit log's records. ids: null lists every snapshot, newest first; the
full inventory only when asked for.
The catalog is embedded and parsed at start (new dependency: toml,
MIT/Apache); the evaluation is a pure function of it and the live
facts, so each configuration is tested without a server. Loopback
endpoints stay on the host; any other configured endpoint leaves it.
Tested: unit tests for the evaluation (a new install's defaults, an
external blob store, a hosted AI endpoint, telemetry off, a tenant's
slice, hosts from URLs, loopback), snapshots, and the fact gathering's
store and duration rules; the compliance system test, extended (the
officer reads the inventory, a plain user is refused, a tenant's
officer sees its slice and no processors, a webhook to another host
becomes a processor and a snapshot names x:WebHook, a retention change
reads through); the system, audit, legal hold and account lock suites;
fork checks. The system suite failed once of three runs with an email
import's blob not found, in antispam.rs; the same happened once in
purge.rs on the previous branch. Nothing here touches uploads; noted
for a separate look.
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.
A locked account can't sign in (it fails as a wrong password does), its
sessions end on every node, refresh tokens stop working, and its Sieve
scripts forward and reply to nothing. Mail keeps arriving.
Delegates get real ACL grants on the account's mailboxes, calendars,
address books and files at read, organize or full, with the rights they
replaced restored on unlock. Folders made later are granted after the
create and in a daily sweep. Organize delegates can't destroy; send-as
needs organize or full. The JMAP session marks delegated accounts in
urn:inbuxa:jmap.
New inbuxa:AccountLock object with get/set, permissions 665-668, and a
Compliance > Locked Accounts entry in the schema. Lock, unlock and
delegate changes need a reason and are audited; delegate access and
writes are audited too (audit-hold-lock spec AL-1 to AL-12).
What administrators and the server itself do to the control plane is now
recorded, from inbuxa-drafts/specs/audit-hold-lock.md (AU-1 to AU-12):
settings, accounts, domains, roles and every other registry change, with
each field's before and after (secrets only as "changed"); the fork's own
settings objects; administrator sign-ins (and failed ones to administrator
accounts), master-user and recovery-admin sign-ins, once an hour per
account, method and address; access to another account's data through
impersonation or FetchAnyBlob, once an hour; exports and tamper checks;
and registry writes the server makes on its own, named by subsystem
(system:AcmeRenewal, system:auto-ban, system:directory-sync, ...), with a
spam rules update as one summary record.
No change without its record (AU-3): before a set method changes anything,
a pending record per requested create, update and destroy is written; if
that fails, the method is refused with serverFail. Its outcome follows as
a later entry. A change interrupted by a crash stays "unfinished".
Records live in the fork's subspace under L, as one SHA-256 hash chain per
node. The chain's head is stored, never cached, and every append asserts
it, so two writers can't take the same place. Nothing can edit or delete
a record; the daily purge removes the oldest past the retention (default
730 days, minimum 90) and records where the chain now starts, so
verification still passes. security.audit-recorded (647) copies each
record to webhooks, OpenTelemetry and the log; security.audit-write-failed
(648) reports a failed write.
New JMAP objects under urn:inbuxa:jmap: inbuxa:AuditEvent/get and /query
(filters: time, actor, action, target, account, tenant, outcome, address,
text), inbuxa:AuditSettings, inbuxa:AuditExport (CSV or JSON Lines built
on the server, each line with its chain hash, ending in a manifest; the
created object names the blob and its SHA-256) and
inbuxa:AuditVerification. New permissions sysAuditGet, sysAuditExport and
sysAuditSettingsUpdate: the Administrator role gets all three, the Tenant
Administrator role gets read and export, once, on existing installs too.
A tenant administrator sees records whose actor or target is in its
tenant, including a server administrator's changes there.
Sign-in method on the session: access tokens now remember how they signed
in (password, app password, API key, OAuth client, directory, master user,
recovery admin), including across the HTTP credential cache. New OAuth
access tokens carry their client id in the sealed claims; older ones show
as client "unknown" until they expire.
The schema gains the permissions, the two events and a Management >
Compliance > Audit Log link.
Stack: the request layer boxes every inner future where it's made. Without
that, a debug build overflowed the default 2 MB worker stack on a registry
set; measured with the same request, the branch and main now overflow at
the same stack size (between 1856 and 1920 KiB, debug), so the layer adds
nothing measurable.
Tests: unit tests in inbuxa-features and jmap; system::audit::audit_log_tests
(run with --ignored) passes on RocksDB, SQLite, PostgreSQL, PostgreSQL with a
read replica, MySQL, MySQL with a replica and FoundationDB. The system, JMAP
and SCIM suites pass. authorization.rs skipped fork permissions that guard
no registry object; the audit suite checks a plain user is refused instead.
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.
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.
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.
