James's advice is, of course, far more appropriate if you're going to
have the secondary MX there the whole time. You'll probably find that
you'll receive mail there quite often, even when you believe your
primary MX to have been available the whole time.
Just watch out for bringing your exchange server back online after
upgrades or crashes before you've configured it to accept your
domain's email. I've seen huge amounts of bounces for mailing lists
happen for cases like that.
James.
