Release Notes
Bug Fixes
- Fix: "No body available" #262
When the request returns an empty body, choose to skip it and print the account ID and UID information, leaving it for the user to investigate themselves. Otherwise, the IMAP download process will be blocked by this.
- Fix: add in-memory dedup cache to prevent duplicate emails before indexing
Use (account_id, mailbox_id, content_hash) as dedup key with time-based
eviction to bound memory at ~50MB. Check happens before mail parsing,
so duplicate emails skip all expensive work entirely.
- Populate cache from Tantivy FAST columns on startup (7-day window)
- Evict oldest 1/4 of entries when exceeding 300K capacity
- Graceful degradation: populate failure → empty cache, still works
