If you can't run your backup MX with the same (or more stringent)
policies than your main server then don't run a backup MX at all.
Why do you think you need a backup MX host in the first place?
If your primary MX is going to be so un-reliable as to really need a
backup then I would suggest current primary unreachable from the world
and route all your mail through the more reliable server.
