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.
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.
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.
