It is quite strange that an unmounted drive would be woken up by exim -
or any process for that matter. Unmounting should by definition make the
contents of the drive unavailable. All open file descriptors must be
closed to allow for the unmount or in the event of a forced unmount,
they are forcefully closed.
As for periodic access to drives - how often do you run your queue
runner and where is the spool and log files stored?
