Search (PG backend):
- '@' terms match address substrings (from/to/cc), so a partial email like
"dyrektor@wfdif" resolves and narrows predictably as you type
- index each address split into parts, so a bare domain/local word ("wfdif")
finds the address (indexed as one lexeme otherwise); dotted terms fall back to
an address substring
- rank sender/recipient name+address matches above body/subject-only ones
(addr_hit tier, then recency); cursor extended to keep keyset pagination correct
- scripts/reindex_address_parts.py backfills address tokens into existing rows
Inline images:
- extract attachments via a full MIME walk instead of shallow iter_attachments(),
which missed inline images nested in mixed>related>alternative (cid: rendered
broken); has_attachments counts only real (non-cid) attachments
- scripts/backfill_inline_attachments.py stores previously-missed inline images
Folder-name i18n (SPEC §12 M2):
- accent/punctuation-insensitive, multi-delimiter (/ \ .) special-use inference
across ~13 languages; curated names (no substring false positives)
Link security (reading panel):
- links never navigate the message iframe: a parent-side click interceptor opens
http/https in a new tab (noopener) and mailto in the composer (recipient
pre-filled); all other schemes blocked
Backend 292 tests green, ruff + mypy --strict clean; frontend tsc/eslint/vitest clean.

"""Special-use inference from folder names (SPEC §6.3 / §12 M2 fallback).
|
||
|
||
Used only when the server does not advertise the SPECIAL-USE extension. Matching
|
||
is accent- and punctuation-insensitive (so "Wysłane", "Éléments envoyés" and
|
||
"Junk E-mail" all resolve), covers the hierarchy leaf under any of the common
|
||
IMAP delimiters (``/ \\ .``), and recognises provider prefixes like
|
||
``[Gmail]/`` implicitly via the leaf. Names are curated per language rather than
|
||
substring-matched, so a folder like "Sent to John" is *not* misfiled as Sent.
