My secondary MXes are locked down even tighter for that exact reason,
One of the things I'm wondering is whether you could set up a trap up in the high MX records. You'd have to make sure your real mail system never failed badly enough to wander up there, but could you create problems by putting a tar baby up there?
I don't know if I would. I'm sure some legitimate MTAs and DNS servers would somehow sometimes end up with your highest MX. That said, I have indeed not tried it, it may virtually never happen.
