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?
