In our experience the mail which goes to 50 without trying 10 is always
spam. We kept trying to think of a way to reasonably check for this,
and allow it through if the lower MX was actually busy...

Just to clarify here.... You are talking about doing something like:
domain.com 1200 IN MX 10 smtp-1.domain.com
domain.com 1200 IN MX 50 smtp-2.domain.com
You all are saying that most of the spam should be coming in MX 50 right?
I have to admit I've tried this, but it seems like mail continues to
come into the MX 50 even when the primary servers are available. Is
it not correct that the 50 should NOT be tried until the 10 is
unavailable? Or do I have that backwards?
