This is a bad idea. Why? Because you're setting yourself up for the
situation a friend was just in. His main server went down, and the
secondary kicked in. Unfortunately, the secondary server had become
misconfigured (or was never configured correctly in the first place)
and his email started bouncing.
I dunno, I had a case where we were saved by a secondary MX. The main
mail server crashed just before a long weekend and wound up being out
for a week. Being able to push up the queuelifetime on the secondary
MX almost certainly saved mail from bouncing.
Naturally we tested the secondary MX failover when we installed it,
and we would test it again if we ever changed the configuration.
Admittedly this wouldn't happen at a working company where the mail
server would be rapidly replaced. But there are lots of other sorts
of people on the net.
