| In offline operation mode, after the user forces mail check, after it
| succeeds, IMAP should probably log out and disconnect to avoid socket
| timeout if the connection disappears later. If this isn't done, as it's
| currently implemented, when user reconnects to the network and tries to
| poll the remote mailbox, IMAP connection just hangs until it times out.
| When the connection may be available for the short periods of time, this
| may be a critical factor preventing the user from accessing mails.
