The first column listed a thread's `participants`, which the threader builds from
from + to + cc — so every ordinary email read "Sender, You", and the +N badge
beside the avatar counted the user themselves.
`participants` cannot simply be narrowed: the subject-fallback join matches an
incoming message's recipients against it (threader._by_subject), so dropping
recipients would change how mail is threaded. Hence a separate `threads.senders`,
holding only from addresses, newest writer first — which is also the right thing
for a conversation where several people replied.
Migration 0019 backfills it, so existing threads do not wait to be touched again.
The list falls back to `participants` if a row somehow has no senders, rather
than rendering an empty column.

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.

Labels:
- Moved labelling out of the "+label" message slot into Mail: label chips on the
thread subject bar (removable ✕) and before list subjects, and a Labels submenu
in the per-message Actions menu (multi-select checkboxes + "Create new…").
Per-message storage kept; the reading pane writes a thread-union aggregate so the
list (no message ids) can show chips.
- Sidebar LABELS section rewritten: aligned monocolor tag rows, collapsible
(collapsed by default), inline "+" create popover, hover "−" delete with a confirm
popover, and click-to-filter the mail list by label.
- Backend: batch message/thread label reads, thread aggregate, create + delete
(delete unhooks from all mail), and GET /labels/{name}/threads. Core GET /threads
gained an `ids` param to power the label view. Removed the plugin-pages list from
the Mail sidebar.
Plain-text mail now renders in Lato (self-hosted at /fonts, @font-face'd into the
sandboxed message iframe) instead of the monospace <pre> default.
Calendar right-panel (embed mode): restored the "…" view-options menu, pinned the
toolbar + mini-calendar (only the agenda scrolls), plain "All calendars" button
(inline resets), and the event popover now closes on any outside click.

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.

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.

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).

Rework the conversation view to match the new dark-theme mockups:
- Subject bar gains a print button and an expand/collapse-all toggle (default
action expands all; collapsing leaves only the newest message open).
- Collapsed messages are compact single-line cards (40px avatar, colored sender
name, snippet, relative date) that overlap into a stack; alignment follows the
sort order (top edge for oldest-first, bottom edge for newest-first) and the
always-open newest card overlaps its neighbour in both orders.
- Expanded messages show sender+address (whole header row toggles collapse), a
detail disclosure (From/To/Cc/Subject/Date/Size), the message location
(Inbox/Sent), a read/unread circle (per-message flag toggle), a quick
Reply/Reply-all, and an Actions menu (reply/forward/print/delete). The
Reply/Reply all/Forward bar now sits inside the newest card above a divider.
- Message body: the quoted original is hidden by default with a "•••" toggle
injected after the "On … wrote:" attribution; the iframe now collapses-then-
measures so it shrinks back when the quote is hidden.
- Avatars use the sender's IMAP-account colour when the address matches one of
our accounts, else a stable per-sender hue; two initials for multi-word names.
- Brighter dark-theme border token; new print/expand-all/collapse-all icons.
Backend: add size_bytes to the message envelope (shown in message details).

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.
