I recommend against it.  Unless you find a provider willing to set up a 
virtual domain, and allow you to update it with a database of your 
users, backup MX servers generate a TON of backscatter these days. 
They're not worth putting up, at all.  If your server is down or on 
overload, remote servers will queue and resend messages for a fairly 
long period.  In most situations it's better to rely on that than set up 
a backup MX.
