v1.0.538
Fixed the mail importer hanging indefinitely on a dropped or stalled connection.
Improvement
1- Switched to batched message body fetching with envelope-first de-duplication, so re-running an import skips already-copied messages without re-downloading them (fast resume).
Bug Fixes
3- Added I/O timeouts (connection + per-command) to the mail importer so a dropped or stalled source/destination connection now fails fast instead of hanging forever.
- Failed folders now surface a clear error and are automatically retried up to 3 times.
- Two import jobs can no longer run against the same mailbox at the same time.
