Failure to do header caching for a message will not result in lost mail.

Message insertion is separated from cache insertions. If the message insertion
fails an error is back-propagaged to the sender, but failure during cache
insertion is silent apart from the errors in the logs. Messages without cached
headers can still be retrieved through IMAP or POP3, though in the case of IMAP
they will look funny in the list-pane, and look just fine in the preview pane.
