- Email translation moves from LibreTranslate to our own translator
service (translator/): Mozilla's Firefox Translations models on the
Bergamot engine, fastText language detection (176 languages). Polish,
English, German, French, Spanish and Italian on first start (~350 MB
instead of ~10 GB); Admin panel > Email translation installs and
removes languages. Built and pushed as the `translator` image.
- Every message is translated paragraph by paragraph as plain text;
names travel with their sentence and are kept only where the model
changed them; a sentence start the model copied ("Enclosed") is tried
again in lower case; list markers are not sent
- The Translate button shows only for installed languages
- New logo: favicon, app/maskable/iPhone icons, notification badge,
email logo and calendar copy regenerated; BIMI logo rebuilt in SVG
Tiny PS with its gradients; masks render in browsers
- Launch screen background is the app's dark grey

- Snooze (with a Snoozed folder), keyboard shortcuts with a Settings
section, mail templates (Compose > More > Templates), a Subscriptions
folder with bulk unsubscribe/delete, and tracker blocking with a
Privacy toggle (on by default)
- Own dialogs instead of browser popups; emoji picker in compose; compose
windows survive a visit to Settings
- Sentence completion learned from the user's sent mail (no AI)
- Interface in English and Polish (one file per language, English as the
fallback), picked from the browser on first run, then kept
- Email translation on the server via LibreTranslate: Translate button
and "Translate to...", messages in several languages translated part
by part, names/addresses/emoji/file names/phone numbers kept, an
animated line while translating
- Antispam "Mark as spam" loads with the message, not when the menu opens

Security (ultimo-security-report.md):
- Security headers on every response, the app shell included: they lived at
server level and nginx dropped them in any location with its own header.
CSP, framing, nosniff, referrer, permissions (docker/nginx-security.conf).
- Plain HTTP forwarded by the reverse proxy is redirected to HTTPS; HSTS on
HTTPS responses. server_tokens off.
- Cross-site state-changing /api requests refused (login CSRF), WebSocket too.
- Validation errors in the usual error shape, without the request model.
- New-password policy: max 128, common/own-address/repeated refused,
breached-password check (HIBP k-anonymity, fails open).
- Message HTML: links keep only http(s)/mailto (sanitizer v6); the HTML
endpoint carries its own no-script CSP.
- Outbound fetches pinned to the checked IP (DNS rebinding); external
IMAP/SMTP servers re-checked before each connection; CGNAT and mapped
addresses counted as non-public.
Fixes from testing:
- IDLE loop catches up before idling: mail that came while the worker was
away no longer waits up to 10 minutes.
- Restore from Spam/Trash/Archive moves only the removed messages, not your
reply in Sent.
- Narrow desktop list stacks sender/subject/snippet (subject was squeezed
to nothing at the default width), with hover actions.
- Phone: wide emails scale to fit the screen.
- Singular forms ("1 message"); no zip button for a single attachment;
app passwords no longer claim "never used" for mail apps.
- ruff format across the backend.

Invitations received by email (iMIP): above the message body, a card with
when, what, where (or "Join video call"), the organizer, what else is in the
calendar then (a conflict, else the previous event that day), and Yes / No /
Maybe. Yes and Maybe put the event in the calendar (or update it), No takes
it out — and is still shown as the answer given; each sends the organizer
the iTIP REPLY, then a "Reply sent" toast, and an open calendar refreshes.
A cancellation offers "Remove from calendar". It is the calendar plugin's
message.banner slot (ui/invite.js, imip.py, /invitations endpoints); the SDK
gains the user's own accounts and settings. An Outlook-style invitation sent
only as text/calendar is now kept as invite.ics too.
Calendar: clicking an empty day in the side panel's agenda opens a new event
on that date; a video-call link can be removed (✕ beside Copy); the page
guests see after answering, and our invitations' footer, say Ultimo Calendar
(with the logo).
Attachments: videos (mp4, mov, webm, …) play in the full-screen preview,
paused until played; attachments are now served from disk with HTTP Range,
so a video starts at once and can be seeked.
People tab: everyone in the thread, the user included, A–Z, under the name
any message gives them. Initials circles share one colour rule in the list,
the reading pane and the People tab. The contact view drops its duplicate
"Message" button. A general corner toast (webmail:toast) joins Undo's.

Attachments in the reading pane are tiles with a preview: images and a PDF's
first page, rendered on the server (Pillow, pypdfium2) as WebP of at most
480 px, cached beside the blob store and in the browser. Tiles are all one
size — at most 230 px wide, narrower so three still fit in a row — and frame
each preview by its shape: close to the tile's it fills it, very tall / wide /
square ones show whole over a blurred copy, small ones are not enlarged, PDFs
show the top of the page. The name bar (checkbox, type, name, size, download)
slides in on hover and adapts to the tile's width; files without a preview
get a large type icon. Previews of opened conversations are kept offline.
Forward now carries the original's attachments: new compose attachments
sharing the stored blobs (POST /messages/{id}/forward-attachments).
Mailbox display / Settings → Appearance: "Show a dividing line between
rows" (off by default, per device), with a new switch. Settings drop the
"On a phone…" note, and "Language" reads "Spellchecking language".

A self-hosted LanguageTool (dev: docker/docker-compose.yml, started by
`make up`) checks what the user writes in the compose window, through
POST /api/spellcheck — the browser never talks to the engine directly.
- Marks are CSS highlights over the text, never written into the message: red
wavy for spelling, blue for grammar/style. Clicking one shows the message,
up to five suggestions (applied as typed, so Ctrl+Z undoes them) and Ignore.
The popup, like the link popup, opens above its anchor when there is no
room below.
- Checked after a pause in typing; the signature and quoted original are
skipped; marks on words just edited drop at once; a check overtaken by a
newer one, by turning checking off, or by closing the window is discarded.
- With "auto", text is checked in chunks of lines, each in its own detected
language — LanguageTool settles on one language per request, so a mixed
Polish/English message had every English word flagged as a Polish typo.
- Settings > Appearance: on/off and language (Auto-detect or any of the
engine's languages); the compose window's More menu overrides it for one
message. The browser's own spellcheck steps aside while ours runs, and comes
back when it is off or the server has no engine (503 from the endpoint).

Branding: the page titles and app name are now "Ultimo Email".
Admin panel (now two columns with a divider):
- Users: search by login or by a mail account's address or name (results
only, nothing listed until something is typed). A user opens a window to
change their quota, block/unblock them, or delete them; block and delete ask
for confirmation, and an admin cannot do either to their own account.
- Blocking (users.blocked_at, migration 0019) refuses sign-in with a clear
message and revokes every session; a new user.signed_out event sends the
user's open tabs to the sign-in screen at once. Any "not signed in" answer
now does the same, not only /auth/me. Deleting removes mail accounts (sync
stops), plugin rows (cleared inside the user's RLS context, since plugin
tables have no FK to users), blobs, the search index, sessions and the user.
- Outgoing system mail (migration 0020): SMTP server, port, security, login,
password (vault-encrypted, never sent back), From address and the public
address reset links point to, plus a "Send test" that reports the server's
error.
Password reset:
- "Forgot password?" on the sign-in page asks for the user name and always
answers "If this account exists you will receive an email to your recovery
email address"; the mail goes out after the response, so neither the reply
nor its timing reveals an account, and it is capped at 3 per hour.
- The emailed link (token in the URL fragment, single use, 30 minutes) opens a
page to set a new password. With 2-step verification on, the code is checked
before anything changes; five wrong codes burn the link.
- Settings > Profile: the recovery email can be added, changed or removed,
confirmed with the current password, which must be typed — autofill and
paste are refused (TypedPasswordInput).
Also adds frontend/icons/ultimo-logo-bimi.svg, an SVG Tiny PS version of the
logo for a BIMI record.

A missing avatar was a 404, which the browser reports as an error for every
such sender on every page. It is now an empty 204: the <img> still fails to
decode it and the initials show through, but nothing is logged, and the miss
carries the same one-day browser cache as a hit so it stops being re-fetched.
On a phone the mail list's rows sit 20px apart instead of 7px.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The shared Redis client decodes replies as UTF-8 text, but the avatar cache
holds raw image bytes and a b"none" miss marker: an image could not be read
back at all, and a miss came back as str and crashed on .partition(b"\n").
Only a sender's first request worked; after that, a 500. The cache now goes
through a binary-safe client, get_redis_bytes().

The sender column showed participants[0], and participants are rebuilt
newest message first — so replying to a thread put the user in that slot
and the list named them instead of the person who wrote in.
Thread summaries (list and search) now carry `senders`: the distinct From
addresses of the thread's visible messages, oldest first, with the same
Trash/Spam visibility as the message count. The list joins them and shows
the user's own account addresses as "me" ("me, Alice" for a thread the
user started), and the avatar prefers the other side of the conversation.

Sender avatars (privacy-safe, server-fetched, cached):
- New GET /api/avatar resolves Gravatar (d=404) then the sender domain's favicon
under the SSRF guard, Redis-cached (hit+miss); gated by SENDER_AVATARS_ENABLED.
GuardedResponse gains raw bytes. Shown in the mail list, reading pane, People
panel, and Contacts (overlay that falls back to initials on a miss).
PDF preview:
- Password-protected PDFs now prompt in-place and retry (pdf.js PasswordException),
with a clear error for other load failures instead of a blank overlay. The
password is remembered per attachment until the thread is left; clicking the
field no longer dismisses the overlay.
Contacts:
- Autosave reply recipients: message.sent now carries to/cc (name+email); the
contacts plugin subscribes and adds any non-contact recipients to the Autosaved
group. Contact avatars show the gravatar/favicon via /api/avatar.
Mail views / retention:
- Clicking an account shows all its mail except Trash/Spam (was inbox-only).
- Daily cron autopurge_trash_spam permanently deletes Trash/Spam older than
TRASH_RETENTION_DAYS (default 30; 0 disables) — server EXPUNGE + local rows.
UI polish:
- Ultimo signet logo in the Mail/Calendar/Contacts sidebar header and collapsed
rail; consistent 11px top margin and vertically-aligned header row across states
(fixed-size flex icon buttons); SVG favicon on the browser tab.

Frontend:
- Full-screen attachment preview overlay (AttachmentPreview) for image/pdf/txt
plus office docs: .docx via docx-preview (rendered live into the sandboxed
iframe so header/footer VML images survive), .xlsx via xlsx-preview, and
.odt/.ods/.odp/.odg via a JSZip+DOMParser ODF walker (officeConvert).
- Type-aware attachment icons (green spreadsheet, blue document, red PDF,
image/archive); new document/image/spreadsheet/print SVGs.
- Composer: drag-drop attachments (body drop inserts images inline, else
attaches); inserted images are selectable/resizable/deletable (RichTextEditor).
- Undo-send: "Sending…" banner with live "N seconds to Undo" countdown.
- Search result list: pin/archive/delete update correctly; grey-out only for
search hits; scoped "Search in Trash/Spam".
Backend:
- Search: prefix (search-as-you-type) matching, email-address search, and
address-first result ordering; Trash/Junk excluded with scoped folder search.
- Attachments: RFC 6266 Content-Disposition for non-ASCII filenames; one-time
inline image loading.

Claude-Session: https://claude.ai/code/session_01Rcj3TpydMTzTSmU7kunzf8
Search:
- Meilisearch backend (app/search/meili.py) + factory wiring; pinned SDK 2.7
- Search-as-you-type: debounced query + Postgres prefix matching, built from
the DB tokenizer so full email addresses match (email stays one lexeme)
- Saved searches API + sidebar virtual mailboxes; save affordance in the box
Account sync windows (SPEC §12 M2):
- Choose at setup: All (recent 30d first, then remainder), Last 3 months, New only
- Per-account sync_window + "Sync remaining mail" from settings (idempotent re-run)
- Provider windowed backfill (SINCE/BEFORE), message_count, newest_uid
- migration 0012: accounts.sync_window + backfill_total/backfill_done
Backfill progress UX:
- Floating progress card (auto-dissolves after 10s) + spinning sidebar ring that
fills with the account colour; driven by sync.progress over WS
Thread list pagination:
- Server-side offset + accurate grand total, with filter/order in SQL; working
prev/next across all synced mail
Reading panel:
- "Load images" one-off now actually renders images (?images=1) without trusting
the sender; envelope carries images_allowed so a trusted sender shows no prompt
Threading:
- Subject fallback no longer merges messages that declare an explicit (different)
parent; true siblings still group via a shared-parent reference match. Fixes
unrelated auto-replies with the same subject landing in one thread
Backend 257 tests green, ruff + mypy --strict clean; frontend tsc/eslint/vitest clean.

Claude-Session: https://claude.ai/code/session_01U72FZiF1W1pb8XxyWBTREA
Backend:
- Collapse identical cross-account deliveries in a thread: new messages.delivery_id
(migration 0011) preserves the real Message-ID even when message_id_hdr is
synthesized (§7.1); get_thread groups by it and reports also_in_account_ids; the
list count counts distinct deliveries. Backfill script for existing rows.
Frontend:
- Bundle Lato (SIL OFL) as the UI font; unread mail-list rows use Black weight.
- Mail-list selection: hover-avatar checkbox, tri-state "select all", bulk
Archive/Pin/Delete (Restore/Delete in Archive/Trash/Spam) with a count in the
reading pane; unread blue dot; "also delivered to" note in the thread.
- Spacing/size tuning: sender-column width, icon gaps, avatar size, bar heights,
and a round of -1px font sizes across the sidebar, mail list, and reading pane.

Claude-Session: https://claude.ai/code/session_01U72FZiF1W1pb8XxyWBTREA
Backend:
- Restore returns each message to its original folder (e.g. Sent/Archive) instead
of always the Inbox: new messages.restore_mailbox_id (migration 0010) +
restore_thread_job.
- Drafts: expunge reconciliation for the Drafts poll (provider.list_uids /
_reconcile_drafts) clears phantom "remote" drafts; send + discard drop the
mirrored DB row; adopting a remote draft carries its real attachments into the
compose flow.
- Thread detail/list are folder-aware: individually trashed/spam messages are
hidden outside their folder, Trash/Spam show only their own messages, and the
mail-list message count matches the view.
Frontend:
- Thread reading panel: fix newest-first card overlap/spacing (expand-all and
single expand), hide Reply/Forward on trashed messages, close the Actions menu
on message-body (iframe) clicks, scroll to the inline composer, and prompt
Save draft / Discard on the X close.
- Composer: remount when switching drafts, dirty-tracking to stop duplicate IMAP
mirrors, and close the From/More dropdowns on outside click.
- Sidebar: collapse/expand toggle (icons-only ~60px rail) and a log-out icon on
Sign out.
- Mail-standard printing in a new window with reliable page margins (lib/print.ts).

Backend
- Sent copies: persist locally on send + periodic multi-folder CONDSTORE poll
(Sent/Archive/Trash/Junk) so they thread and show without an IDLE-only INBOX.
- Bcc: transmitted copy omits Bcc, Sent copy keeps it; store/display bcc_addr.
- Drafts: mirror local drafts to the IMAP Drafts folder (append/replace/expunge);
inbound sync of foreign drafts (un-threaded) with adopt-to-edit + dedup by UID.
- Per-user storage quota (5 GiB default) and manual "sync all folders" action.
- Account editing (display/color/server/password) and per-account HTML signature.
- Account view scoped to that account's inbox; new migrations 0006–0009.
Frontend
- Mail-list pagination, folder filters (All/Unread/Pinned), sort toggle, refresh.
- Aligned + widened mail-list margins; reading-pane bars fixed height.
- Rich-text composer: color palette, highlight, image; attachments; expand/pop-out.
- Signatures: auto-insert for new mail, replace on From change, reply insert.
- Restore/Delete actions per folder; drafts view merges local + remote, date-sorted.
