Files, events and contacts are noted when deleted for good and archived by
the unindex task when retention is on; Sieve scripts are archived at
deletion. A restore goes back to its folder, calendar or address book if it
still exists, takes a free " (restored)" name, comes back inactive for
scripts, and is refused over quota with the item left archived.
Acceptance tests 6, 8 and 12.
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.
A live mask accepts mail at RCPT TO and delivers to its owner, with an
X-Masked-Email header naming it. A disabled mask files straight to Trash,
past the owner's Sieve script. Deleted and expired masks are refused like
unknown addresses, without being cached as unknown. Mail moves lastMessageAt
and turns a pending mask enabled. Sub-addresses on a mask work.
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.
Subspace _ holds the fork's own data, with its own SQL table and RocksDB
column family, and is part of backup. The masked_email module keeps each
mask's state, last mail and pending deadline beside upstream's record, an
index from address to mask with tombstones, and a per-account change log;
and generates addresses in the fork's format.
tests/src/system/tenant.rs is new, and system_tests calls it again without
the pending-rebuild gate. tenant_tests runs it alone; tenant_compat is test 15,
ignored until a copy of INBUXA's data is provided.
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.
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.
