Oh this thread is rather confusing now !

I am just trying to reframe your words to make myself clearer about your problem

1) You mean to say you have Destiny as the primary MX and Mystique as
the secondary MX ?
When mail hits on Destiny some problem oocurs (it can be a connection
time out or a busy server ) and  the mail goes to Mystique instead.
But in normal scenarios when there is no load or much traffic on the
server you are observing that the mail still goes to mystique.

2) Is Destiny and Mystique directly available on the Internet via MX
records or you have some kind of load balancer which redirects the
mails to Mystique incase Destiny is overload.

I know I have repeated a lot of stuff over here again and again, but
trying to make myself clear.
