New crate crates/features (inbuxa-features), AGPL-3.0-only, holding the
tenancy rules. Hooks in common: a tenant's roles and permission lists cap
its people's permissions; a change to a tenant, or to a role a tenant holds,
drops its members' cached permissions; delivery and every other write check
the tenant's maxDiskQuota; usedDiskQuota reads the tenant usage counter.
The default Tenant Administrator role gains sysTenantGet and sysTenantQuery.
Test 3 expects invalidForeignKey, as MT-3 says. A tenant admin reads its own
tenant through sysTenantGet and sysTenantQuery, added to the default Tenant
Administrator role for new installs only. The server adds nothing for MT-7's
dashboard list. The MT-19a submission warning is deferred. MT-22's logo is
the urn:inbuxa:jmap account capability's logo field (contract C-1).
Discovery and a contract version in the session; front ends configured once
(x:FrontEnds); OAuth with required registration, first-party clients,
server-hosted sign-in and consent for everything else; per-grant revocation;
cross-origin limited to the front ends; an admin lane by scope; push
unchanged. Records what upstream does today, including that it accepts any
client and redirect URI by default, and the phishing that allows.
inbuxa --version, the banner, startup events, OpenTelemetry and the JMAP
implementation string read "2026.9.18 (Stalwart 0.16.22)". The base comes
from Cargo, which keeps following upstream so version bumps merge cleanly.
Received headers and IMAP ID carry the INBUXA version.
Administration is no longer moving wholesale into ihasmail. INBUXA Admin, a
fork of the schema-driven webui (no Enterprise-only code, ordinary fork),
covers the whole server, setup and recovery from its own deployment.
ihasmail keeps its account and tenant administration. Contract additions:
the inbuxa-admin OAuth client, cross-origin access limited to the two
front ends (the server currently allows every origin), and relative OAuth
endpoints on servers with no public URL.
- 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.
The early return for a missing redirect_uri came before the logo loader,
so the logo stayed hidden behind data-loading. An upstream bug, surfaced by
the rebrand check.
Upstream's Dockerfiles and CI pass --features "... enterprise" on the cargo
command line, which the manifest edits don't reach. 11 occurrences at
v0.16.22. Dockerfile.build and Dockerfile.fdb are now scanned too, whatever
their extension.
One branding module (types::brand!) supplies the name to every protocol
greeting, the HTTP realm, the startup banner, Received headers, the
user agent, the IMAP ID response and calendar PRODIDs. The sign-in and
calendar pages take ihasmail's palette and font and the INBUXA logo, and
calendar emails embed the INBUXA lockup. Default calendar and address book
names follow. Protocol identifiers (urn:stalwart:jmap, vnd.stalwart Sieve
extensions) and upstream copyright notices are unchanged.
