What I was talking about was using a backup mx that simply queued mail 
until the primary came back up... in todays internet, it provides very 
little benefit, since the servers attempting delivery will simply retry 
later anyway...

Having a backup smtp server that can actually step in and REPLACE the 
funcitonality of your primary is another thing entirely, and I'm all for 
redundancy where practical... :)
