I'm with you, Joe :-).
At first, backup MX seemed like a good idea. When you think about it, if you
SBS is down, and a backup is receiving email - the senders may wonder why
you're not responding ;-).
Without backup MX - senders generally know a) mail has been delayed, and b)
if your server is down long enough, that the email will not be delivered.
That's the way it should be!
The key of course, is to keep the SBS in good shape. Off-line should be a
very temporary condition. With today's recovery solutions, even the loss of
the hardware would allow for SBS to be back up as a VM in a matter of hours.
