    That still doesn't help you if the moron in question has the keys to the
room, and the cable isn't routed entirely within the physical constrains of
the rack. Yes, this has happened to us -- fortunately, we had good software
and didn't lose any mail messages as a result.

    Fundamentally, there is no substitute for good software. You can throw
however much hardware you may like at the problem, but if the software is
screwed up, there's only so much you can compensate for, regardless of how
much money (or time) you spend. It would be much better for everyone inv
olved if you instead spent your money (and time!) in places where it could do
some real good, such as getting improved software.

    This statement is true regardless of what particular piece of software
you're talking about -- MTA, filesystem, or operating system.
