shukiv 246df49c03 fix(impersonation): reconcile stale persisted account chip after handoff
After a master-user impersonation handoff (GET /api/auth/impersonate) the server
swaps the slot-0 session cookie but the client's persisted account registry
(account-registry / auth-storage in localStorage) still lists the previous
account, so the top-left account chip keeps showing the old mailbox until a
manual sign-out. Redirect impersonation to /?impersonated=1 and add a headless
ImpersonationReconciler that drops the stale persisted account/auth state (and
server-derived caches) then reloads to a clean URL, so the app rehydrates empty
and re-derives the single account from the fresh session. Cookies untouched, so
the just-granted session survives. Runs exactly once.

Reported downstream: shukiv/jabali-panel#646.

Stefan Hildebrandt f188e29152 feat(settings): always show the Unified Mailbox switch in Layout settings
Drop the `accounts.length > 1 || hasGroupInboxes` gate that hid the
Unified Mailbox toggle for single-account users with no visible shared
folder. The admin `isSettingHidden('enableUnifiedMailbox')` policy gate
is preserved, so admins can still hide it.

Stefan Hildebrandt 9c6292b4b7 fix(email): restore the sender identity when reopening a draft
Reopening a draft reset the composer's From to the default identity. The
edit-draft handler matched the draft's saved From against the active-account
identity list by email only, so two identities sharing an address (a default +
an alias differing by name) collided — the wrong one was picked, or with
cross-account namespaced ids none was.

Add findDraftIdentityId (name+email, normalized, +tag fallback) and match against
the same list the composer renders (the flat cross-account list when multi-
account is on). Wired into both the classic and Pro edit-draft paths. Unit tests
plus the un-pinned 07-drafts integration spec.

dealerweb 21ea5009f4 i18n: localize the editor toolbar in all 23 locales
The rich-text editor was the last hardcoded-English surface in the
composer: 21 tooltip titles, the eight table-menu entries, the "Remove
color" entry and the table size picker's "Pick size" label were plain
strings while every other menu in the app is localized.

All of them now come from a new email_composer.toolbar namespace,
translated into all 23 locales using each platform's established
editor terminology (Word/Docs conventions - de "Formatierung löschen",
ar "مسح التنسيق", ja "書式をクリア", ...). The link prompt stays "URL",
which is the same term in every language.

Tooltips and self-sizing dropdowns have no width constraints, so longer
translations are safe everywhere.

dealerweb af2b00dd35 Fix: stop resurrecting deleted rows in the mailbox refresh merge
Fixes #592.

refreshCurrentMailbox merges the refreshed first page with the already
loaded list, appending existing entries beyond a cutoff. That cutoff
was derived from the refreshed list's length - so whenever a folder
shrank, the fresh page was shorter than the stale list and the loop
re-appended the deleted rows from stale local state, despite the
comment right above promising the opposite.

The visible result is the reported bug: after sending a draft, the
Drafts view keeps showing a ghost row for the already-destroyed draft.
The send actually succeeded - resending the ghost delivers the mail
again, which we reproduced with a live JMAP trace: four successful
submissions, an empty server-side Drafts folder, a notFound ghost id,
and five delivered copies. Deriving the cutoff from the page size
fixes the shrink case while preserving the merge's intent for
arrivals and loaded deeper pages; regression tests cover all three
shapes.

Also surface post-send filing failures instead of dropping them, as
flagged in 4dc76bbb's follow-up note: a rejected onSuccessUpdateEmail
patch or old-draft destroy now logs the server's error details and
returns a filingError on SendEmailResult, and the UI shows a warning
toast (all 23 locales) so a stale draft row is never again mistaken
for a failed send. A plugin veto of the send leaves a debug trace.

xhzeemandLinus Rath 23a017d4b7 fix(rtl): set dir=ltr on identity <option> elements
The From-identity picker in the composer and the template form use a
native <select>, so the earlier <bdi> fix can't apply there - browsers
render <option> as plain text and strip any nested markup. The native
OS-rendered option list still respects the dir attribute directly
though, so setting dir="ltr" on each option fixes the same bracket-
mirroring bug for "Name <email>" entries in that native popup.

xhzeemandLinus Rath c7250dc921 fix(rtl): isolate Latin address text ("Name <email>") from RTL bidi reordering
Unicode's bidi algorithm treats < and > as mirrored characters. When a
plain "Name <email>" string is rendered as a text node inside an
RTL-inherited container, the browser swaps and reorders those brackets
for the whole run, producing garbled output (e.g. "<Maria Lopez
<maria.lopez@company.example" instead of "Maria Lopez
<maria.lopez@company.example>").

Wrapped the affected text in native <bdi>, which auto-detects its own
paragraph direction from its content rather than inheriting the
ancestor's - so a Latin address renders LTR and a genuinely
Arabic/Hebrew/Farsi name still renders RTL, both correctly, in:
- recipient-popover.tsx (shared by the email viewer's From/To/Cc/Bcc
  detail rows and the calendar invitation banner's organizer row)
- email-composer.tsx's read-only From display
- eml-preview.tsx's From/To header lines

Left the equivalent <select><option> cases (composer identity picker,
template identity picker) and the composer's quote-header text (which
becomes actual email body content, already isolated per-paragraph by
the existing TextDirection tiptap extension) out of scope - both need
a different fix approach than <bdi>.

xhzeemandLinus Rath 80f76abc38 fix(rtl): flip JS-positioned popovers (storage, logout, account switcher, calendar picker)
These popovers are portaled and positioned via inline styles computed
from getBoundingClientRect() rather than Tailwind classes, so the
logical start-0/end-0 fix doesn't reach them. They always anchored to
the physical right of their trigger (rect.right + 8), which in RTL
pushes them further into the edge the trigger is already flush against
instead of toward the visible content area.

Added isDocumentRTL() to i18n/direction.ts and used it to mirror the
computed position in:
- navigation-rail.tsx: storage quota popover, logout/switch-account menu
- account-switcher.tsx: both the rail and expanded-sidebar variants
- calendar-invitation-banner.tsx: the "add to calendar" picker

xhzeemandLinus Rath adb8686293 fix(rtl): anchor floating menus with logical start/end instead of left/right
Popovers and dropdown menus across the app (sub-address helper, calendar
toolbar/color pickers, contact/template/attachment menus, rich text editor
color and table pickers, unsubscribe confirmation, composer send menu)
were anchored with physical `left-0`/`right-0`. In RTL locales those
don't flip with the trigger, so the menu detaches from the button that
opened it. Switched to Tailwind's logical `start-0`/`end-0` (and the
matching `rounded-s-*`/`rounded-e-*` corners on hover-action overlays)
so they mirror correctly for RTL locales (ar, he, fa) while staying
identical in LTR.

components/providers/intl-provider.tsx keeps its own static ALL_MESSAGES
map separate from i18n/request.ts's server-side loader. It was missed
when ar was added, so switching to Arabic flipped to RTL (direction.ts
knew about ar) but rendered English text (messages lookup fell through
to the en fallback).

Shuki VakninandLinus Rath 6dfcb07b9a feat(accounts): remove a specific account from the switcher
The switcher only offered 'sign out of active' and 'sign out of all' — no
way to drop a single non-active account (e.g. one stuck in an error state you
can't switch into to sign out). Add a hover × on non-active, non-default rows
and a removeAccount(id) auth action that tears down the client, drops it from
the registry, and clears its per-slot session/token cookies.

Stacks on the switcher redesign in #517.

Stefan HildebrandtandLinus Rath d5017a211f feat(email): open external links in a new tab (safely)
External web links (http/https) in rendered email bodies open in a new browser
tab with target="_blank" rel="noopener noreferrer". mailto:, tel:, and in-page
#anchors keep their default behavior instead of spawning a blank tab.

The plaintext render path is already handled on main by #594 (ADD_URI_SAFE_ATTR
in PLAIN_TEXT_RENDERED_CONFIG), so this no longer adds its own hook there — the
plaintext linkifier only ever emits http(s) anchors, so the config's declarative
exemption is sufficient. This change covers the paths #594 did not:

- iframe HTML render: both anchor passes (the DOMPurify hook and the post-render
  DOM walk in email-viewer.tsx) set target=_blank on EVERY <a>, including
  mailto:/tel:. Now scoped to http(s) via the shared applyNewTabToAnchor()
  helper (http/https -> target+rel; mailto/tel/#/other -> strip target/rel).
- sanitizeI18nHtml: the same DOMPurify strip dropped target/rel from translated
  links (e.g. the docs link in settings.security.not_available, target="_blank"
  in 19/22 locales). Keep the author's target and harden rel="noopener
  noreferrer".

Tests: unit coverage for isHttpLinkHref / applyNewTabToAnchor / sanitizeI18nHtml
plus an integration suite over the real plaintext and HTML/iframe render
pipelines. The plaintext-hook-specific cases are dropped as redundant with #594.

Shuki VakninandLinus Rath f51ec50443 feat(settings): add "Refresh cached data" recovery action
When the mailbox view gets into a stale or wrong state, the only escape
was the browser's "clear site data" — which also wipes the saved account
list, forcing a re-login of every account.

Add a non-destructive "Refresh cached data" button under Settings →
Data. It clears the server-derived caches (contacts, calendars,
identities, per-account snapshots) and reloads so they re-fetch fresh,
while preserving accounts, sessions, settings, themes and user content
(templates, S/MIME). Two-click confirm to avoid an accidental reload.

English strings added across all locales (translation follow-up); unit
tests cover the cache-clear (keeps account-registry/auth/prefs) and the
reload.

Shuki VakninandLinus Rath f15edd336b feat(send): 'Send now' on the send-delay toast

'Send now' action that reschedules the delayed submission for immediate release,
so you can skip the undo window without waiting it out. Adds an optional
secondaryAction to the toast component and carries identityId on the pending
undo-send state so the reschedule can target the right identity.

dealerwebandLinus Rath a779e101e6 Fix: label the close-dialog draft button with the generic Save
"Save Draft" made the third button of the save-or-discard dialog wrap
onto two lines in several languages (German "Entwurf speichern", French
"Enregistrer le brouillon", ...) while its siblings stay one line. The
dialog title already says the draft is what's being saved, so the
button now uses the existing generic common.save key - one short word
in every locale, no new translations needed.

email_composer.save_draft had exactly this one consumer; the dead key
is removed from all 22 locales.

Linus Rath 739b72d251 Merge pull request #509 from hildebrandttk/feat/unified-mailbox-account-scope
Feat/unified mailbox account scope

Rework the sidebar "All accounts" into an account-bounded "Unified Mailbox"
by default, with cross-account merging as an opt-in (admin-gated) sub-option.
The standalone per-account "All Mail" virtual folder is folded into the unified
All mail / Unread / Starred entries.

Conflict resolution notes:
- stores/settings-store.ts: both main and this branch independently added a
  per-account default-identity (#507) migration at different versions (main v6,
  branch v7). Merged migration is version 7 using the refactored migrateSettings
  function; the unified-mailbox rework is guarded at `version < 7` so users who
  stopped at main's interim v6 identity bump still receive it, while the #507
  identity-map coercion stays at `version < 6` so their populated map is kept.
- stores/auth-store.ts: kept main's applyPreferredIdentity (superset with the
  pre-#507 legacy migration).
- stores/email-store.ts: removed the ALL_MAIL_MAILBOX_ID paths (folded into the
  unified views) while preserving main's plugin hooks (onSearchResults /
  onEmailsFetched); adopted advancedSearchCrossViewEmails for advanced cross-view
  search.
- components/settings/layout-settings.tsx: kept main's faviconUnreadBadge setting
  alongside the new unifiedCrossAccount toggle.
- integration/: union-merged the two independently-authored suites - branch suite
  is authoritative (matches new behavior) with main's shared-identity (#569) group
  infrastructure preserved.
- components/email/email-composer.tsx: dropped a duplicate data-testid attribute
  introduced by the auto-merge.

dealerwebandLinus Rath 6f278845f3 Feature: text color picker in the composer toolbar
The rich-text editor already registers the TextStyle and Color
extensions so that colored text pasted or quoted from incoming mail
survives editing - but there was no way to set a color yourself.

Adds a "Text color" toolbar button next to the strikethrough control,
wired to the already-loaded extensions: a 2x8 preset swatch grid plus a
"Remove color" entry, following the table button's dropdown pattern
(wrapper ref, outside-click close, same popover styling) and the table
size picker's swatch grid. The button's baseline icon renders in the
currently active color, so the selection is visible without any extra
indicator element.

No new dependencies and no locale changes; the toolbar titles in this
file are plain English throughout, and Clear Formatting already removes
colors via unsetAllMarks.

honzupandLinus Rath 334fdbfb86 feat: show unread count badge on favicon
Closes #560.

Composes the active inbox's unread count over the base favicon as an SVG
badge, served as a percent-encoded data: URL, so new mail is visible on a
tab that is not focused — including when the browser collapses tabs to
icon-only, where a title-based count disappears entirely.

The base icon is read from the rendered <link rel="icon"> rather than from
config, so admin and per-domain branding overrides are inherited for free:
the count is drawn on whatever logo the deployment actually serves. Keeping
the badge in SVG rather than rasterising to a canvas also means the browser
can rasterise it at whatever size it asks for, so a HiDPI tab is not served a
16px bitmap.

Notes on the approach:

- The badge link is an *additional* icon link that we append and mark as
  ours; we never remove or mutate a link we did not create. Next's metadata
  icons are rendered by React, which keeps a fiber pointing at that DOM node,
  so removing it would leave React holding a detached node and throw
  "Cannot read properties of null (reading 'removeChild')" on the next
  commit that deletes the fiber. Appending instead means the last-declared
  icon wins, and non-SVG fallback links survive with their type/sizes intact.
  (The usual recipe for this feature — assign canvas.toDataURL() to the
  existing link's href — does both of the things that break here.)

- Every change of state is an *insertion* of a fresh link of ours, never a
  mutation or a removal, because that is the only signal a browser reliably
  re-reads the favicon on. Firefox ignores an in-place href change, and it
  equally ignores a removal — so clearing the badge by deleting our link left
  a stale count painted on the tab until a hard reload. Clearing it instead
  inserts a new link of ours carrying the original base href.

- Holding last place has to be defended: on a client-side navigation React
  re-hoists its metadata icon link into <head>, landing after ours, and the
  base icon silently wins again. A MutationObserver on <head> moves our own
  link back to the end whenever a foreign icon link appears — moving only our
  node, never anyone else's. It no-ops once ours is last again, so a move
  cannot feed itself.

- The badge is a full-width band across the foot of the icon, drawn to the
  metrics measured from Gmail's own 16px favicon: band height 0.625 of the
  icon, digit cap height 0.44, flush to the edges, corners rounded by about a
  pixel. Full width is what keeps a three-glyph label legible — rounded ends
  waste exactly the horizontal space it needs. Neutral white with black digits
  rather than the conventional red: faviconUrl is admin-overridable and
  Bulwark's own icon is rgb(219,45,84), so a red badge sat red-on-red.

- The base SVG may be admin-uploaded, and the branding route deliberately
  serves it under a sandboxing CSP because SVG can carry script. Re-emitting
  it as a same-origin data: URL would un-fence that, so script, foreignObject
  and every on* handler are stripped before serialising.

- Mounted in the root layout, not on the mail route: the badge belongs to the
  tab, so mounting it on the page would clear it on every hop to settings,
  calendar or contacts.

Stefan HildebrandtandLinus Rath 578339c400 test(integration): composer From offers shared/group identities (#569)
Provision a Stalwart group (team@example.org) with carol as a member before her
first login, and assert the composer's From selector offers the group address.
This confirms the group-membership scenario of #569 already works out of the
box: Stalwart returns the group's send-as identity on the member's own account,
so the app's normal single-account identity load surfaces it (identities.length
> 1 -> the From <select> renders with team@).

- stalwart: create the `team` Group in plan-accounts and add carol via
  User.memberGroupIds in the entrypoint (id resolved after apply, like
  DOMAIN_ID). carol, not alice/bob, so the sync specs stay unshared.
- helpers: GROUP config, openComposer/composerFromOptions, and JmapClient
  accounts + sharedAccountNames (Identity/get needs the submission capability).
- composer: add data-testid="composer-from" to the From <select> and its
  single-identity <span> fallback.

- integration/ stack: Stalwart (declarative bootstrap: alice/bob/carol,
  submission + IMAP listeners, permissive CORS) + webmail (dev mode, so the
  browser's plaintext cross-origin JMAP calls aren't blocked by the prod CSP).
- Helpers: dependency-free SMTP submit client, JMAP client for seeding /

  locale-independent folder-counter reads).
- Specs: login, single-account sync (receive/read/move/delete/folder-create/
  burst) and multi-account (per-account isolation + cross-account Unified
  Inbox aggregation + background-account delivery). 12 tests, all green.
- Add focused data-testid hooks to the mail UI (folder rows + counters, email
  list items, account switcher, composer) for stable selectors.
- Exclude examples/ and integration/ from tsconfig/eslint/.dockerignore.

Stefan HildebrandtandLinus Rath 01e5cd69cf fix(identity): sync default sender identity per account (#507)
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.

Stefan HildebrandtandLinus Rath 37152504b4 feat(composer): drag-to-reorder To/Cc/Bcc recipient chips (#593)
Recipient chips could already be dragged between the To/Cc/Bcc fields, but a
drop always appended and same-field drops were a no-op, so recipients could not
be rearranged without deleting and re-adding them.

Add positional drag-and-drop: while dragging a chip, an insertion caret shows
the gap it would land in (based on which half of the hovered chip the pointer
is over, mirrored for RTL); dropping inserts it there.

- same-field drop reorders the chip locally (via onChipsChange), using the
  source index carried in the drag payload (fromIndex) and adjusting for the
  removal shift; dropping onto its own position is a no-op;
- cross-field drop inserts at the drop position: handleMoveChip gained an
  optional toIndex (omitted = append, e.g. dropping onto a hidden Cc/Bcc
  button, preserving existing behaviour);
- per-chip onDragOver computes the target gap; the container handles the
  trailing gap (past the last chip / over the input).

No new user-facing strings (the caret is purely visual), so no locale changes.

Tests (components/email/__tests__/recipient-chip-drag.test.tsx): reorder to end
/ front, self-drop no-op, cross-field positional insert, and caret visibility.
Also add the missing findComposeIdentityId export to the reply-identity mock in
the recipient drag/paste suites so <EmailComposer> mounts in compose mode.
