Backup Mail Server Questions

But, with backup MX, *you* are in charge of all mails in the queue. 
Routing messages to a new primary becomes so much more easier.

End users are less likely to get "couldn't deliver yet but will keep 
trying" messages from their own smtp-server. (It appears to me that most 
users, when given such automated notice, start running around in panic 
and making frantic, unnecessary phonecalls. This was different some 
years ago.)
