The default sender identity (`preferredPrimaryId`) lived only in the
browser-local `identity-storage` store and was never written to the synced
settings, so the choice was lost on clearing site data / switching browsers and
never appeared in exported settings.
Persist it 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.
This supersedes the earlier username-keyed fix that had landed on main: the
username-keyed map, `loadIdentities()` fallback write, and the
`applyPreferredIdentityOrdering` store action (plus its settings-store hook)
are removed so a single account-keyed mechanism remains.
- settings-store: `preferredIdentityIds` (accountId -> identityId) in state,
defaults, export, import (non-record guard), rehydrate coercion, v6 migration.
- auth-store: `applyPreferredIdentity(accountId?)` reorders the active account's
identities once synced settings load, and performs the one-time migration of
the pre-#507 browser-local default into the synced map (keyed by accountId).
Invoked from every `loadFromServer().finally()` (login / OAuth / SSO / switch
/ restore). `loadIdentities()` now only applies the local fallback ordering.
- identity-manager-modal: the star action writes the choice by `activeAccountId`.
- identity-store: `preferredPrimaryId` kept as a local (sync-off) fallback.
- tests: per-account independence, export/import round-trip, import guard, and
applyPreferredIdentity reorder / active-account gating / local-default
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
This release significantly expands internationalization support and adds comprehensive identity management features.
Internationalization (i18n):
- Add 5 new languages: Spanish, Italian, German, Dutch, Portuguese
- Expand from 3 to 8 total supported languages
- Redesign language switcher for better scalability (dropdown UI)
- Complete translations for all features across all languages
Identity Management:
- Multiple sender identities with per-identity signatures
- Sub-addressing support (user+tag@domain.com)
- Context-aware tag suggestions for sub-addresses
- Identity badges in email viewer and list
- Full CRUD operations for managing identities
Newsletter Management:
- RFC 2369 List-Unsubscribe support (one-click unsubscribe)
- HTTP and mailto unsubscribe methods
- Security validation prevents XSS attacks
- Two-step confirmation with persistent dismissal
Security & Accessibility:
- Dark mode email readability (intelligent color transformation)
- WCAG 2.0 Level AA color contrast compliance
- Comprehensive XSS prevention with validation utilities
- Unit test coverage for security-critical code (57 validation tests)
Testing:
- Add unit tests for validation utilities
- Add unit tests for email sanitization
- Add unit tests for color transformation
- Full test coverage for XSS attack vectors
