IMAP import wrote a whole folder in one transaction and stopped the folder at the first message it could not import. A crash near the end of a large INBOX kept nothing, and one bad INTERNALDATE lost the rest of the folder. Worse, when a folder stopped early, fetches still in flight for it could be filed into the next folder's mailbox. - The transaction is committed after every fetch chunk. Each message is written in its own savepoint, so what is committed is always whole, and a rerun fetches only the UIDs still missing. - A message that cannot be imported is rolled back on its own, logged with its folder and UID, and counted as failed; the folder carries on, and the message stays out of the UID map so the next run tries it again. Archive and I/O errors still stop the run. - Fetch jobs and events carry a folder generation. Moving to a new folder cancels queued work for older ones, and any event from an older generation is dropped, never filed. Shutdown drains in-flight events before joining the workers, so it cannot hang on a blocked worker. - INTERNALDATE month names are matched in any case. - Maildir import gets the same per-message savepoint, and commits every 500 new messages instead of once per folder.
