  I can't say enough about this book, it's very dense, but worth reading
  a couple of times.  Anyone running high-performance email systems would
  be well served by reading it.

  The other thing to keep in mind is that there is more to filesystems
  than speed when it comes to email - they also have to be reliable and
  be able to insure message storage.  Of course, for MD's temp space the
  opposite is true - message persistance (beyond a few seconds) isn't
  important and speed is all that matters.  See Christenson's book for
  a more educated discussion of these issues.
