The default sender identity (`preferredPrimaryId`) lived only in the
browser-local `identity-storage` Zustand store and was never written to
the server-side synced settings. As a result the choice was lost when
clearing site data or switching browsers, and never appeared in the
exported settings JSON.
Persist the default identity in the synced settings store, keyed per
account (`preferredIdentityIds: Record<accountId, identityId>`), mirroring
the existing per-account `allMailFolderIds`. Per-account keying is required
because JMAP identity ids are account-scoped and would otherwise collide
across accounts / the unified mailbox.
- settings-store: add `preferredIdentityIds` to state, defaults, export
(so it shows in exported JSON), import (with a non-record guard),
rehydrate coercion, and a v6->v7 migration.
- auth-store: add `applyPreferredIdentity()`, invoked in every
`loadFromServer().finally()` (login / OAuth / SSO / switch / restore) so
the synced default reorders the active account's identities once server
settings load (the composer defaults From to identities[0]).
- identity-manager-modal: the star action also writes the choice to the
synced per-account map, triggering server sync + export inclusion.
- identity-store: keep `preferredPrimaryId` in local persist as a sync-off
fallback; synced settings are the durable cross-device source of truth.
- tests: per-account independence, export/import round-trip, non-record
import guard, and v6->v7 migration.
When authenticating with a local-part username (e.g. 'user' instead of
'user@domain.tld') on Stalwart 0.15.x, the default sender could resolve
to an alias identity instead of the canonical mailbox address.
- Add emailMatchesUsername() helper that matches local-part usernames
against full email addresses (e.g. 'user' matches 'user@domain.tld')
- Prefer canonical identities (mayDelete=false) over aliases as tiebreaker
- Add preferredPrimaryId to identity store (persisted to localStorage)
so users can explicitly set their default sender
- Add 'Set as Primary' star button in identity manager modal
- Fix sendEmail() fallback identity resolution for local-part usernames
- Add i18n strings for all 8 supported locales
Fixes#43
- Add syncIdentities() to auth store to propagate identity changes from
identity store, fixing stale data that caused save failures and duplicates
- Call syncIdentities() after every create, update, and delete in the
identity manager modal
- Switch email composer to read identities from identity store for
consistency with the rest of the app
- Append identity text signature (with RFC 3676 separator) to email body
when sending from the composer and quick reply paths
- Add tests for syncIdentities and signature appending logic
