Replaces the global allMailFolderIds (string[] | null) with a per-account
Record<accountId, string[]>, so each account chooses which of its own folders
the "All Mail" view merges. A missing entry = "not configured" (defaults to
every no-role folder); an explicit [] = "no folders".
- settings-store: type/default -> Record (default {}); persist version 4 -> 5,
migration drops the legacy global list (the active account isn't known at
migrate time); onRehydrate + importSettings coerce/ignore any non-record
(legacy global string[] | null) shape. isPlainRecord() guard.
- email-store.resolveAllMailJmapIds: reads the entry for the account the view is
scoped to (viewingAccountId ?? activeAccountId); undefined -> all no-role,
[] -> none.
- layout-settings: read/write the active account's entry; when more than one
account is logged in, an italic hint names the account the selection applies
to (settings.appearance.all_mail.account_hint, 19 locales; de/ro translated).
- Test: stores/__tests__/settings-store-all-mail.test.ts (per-account
independence, explicit-empty vs not-configured, importSettings legacy guard).
Add cross-account aggregate mail views and make group/shared (delegated)
accounts first-class in every aggregate view. (The unified mailbox, the "All
Mail" view, and "include group inboxes" already exist on main; this branch adds
the cross-account views and the shared-account correctness work.)
New views (admin-gated + per-user toggle, nested under Unified Mailbox):
- Cross-account "All accounts": All unread / All starred / All mail across every
connected account, including shared/group folders. Each list labels the source
folder of every message.
Source reference on aggregated emails (the core of the shared-account work):
- Replace the overloaded `accountId` with two explicit, always-set fields:
`sourceClientAccountId` (the login the mail is reachable through) and
`sourceAccountId` (the owning JMAP account). `accountId` stays display-only.
- Resolution is branch-free everywhere: pick the client by sourceClientAccountId,
pass sourceAccountId as the JMAP accountId (no-op for personal), read the
owner's mailbox list cached by JMAP id. No capability scan.
Shared/group-account correctness across all aggregate views:
- Route open (click + auto-fetch), thread/conversation open + reply-refresh,
mark read, star, move, delete (account-scoped trash), archive (owner-routed
createMailbox / fetchAccountMailboxes), and spam + undo via the source ref.
- Add accountId params to toggleStar / batchMarkAsRead / batchDeleteEmails /
createMailbox where missing.
- Fix local unread/total counter math for shared folders via emailInMailbox()
(matches namespaced shared ids and bare own ids).
- Keep the unified/cross virtual selection on background mailbox refresh (no
jump back to inbox after deleting in All Drafts/Junk).
Junk UX:
- In "All Junk" the spam action becomes "not spam" in the viewer, context menu,
and list hover icons; undo routes shared mail back to its own inbox.
Admin:
- Policy gates crossUnread/Starred/AllViewEnabled, each noting the matching
per-user toggle (allMailViewEnabled clarified too).
i18n / docs / tests:
- locales (19): cross-view labels + descriptions and hover not_spam, translated
in all shipped languages.
- FEATURES.md + README.md document the new views and group-account support.
- Tests for shared-account routing (single + batch + undoSpam), decoration, and
unified-selection preservation.
