Or, secondly - as was cleverly suggested to me a while ago - setup a 3rd MX that has a IN A PTR to your primary MX, and make it the highest priority...

e.g.

mx0.mydomain.com   PRI   20
mx1.mydomain.com   PRI   30
mx2.mydomain.com   PRI   40 (Which is really just a different name for mx0)

That way, you'll probably find most the spam hits the highest priority MX (which is, in reality your primary MX).

I think you mean "highest-numbered" MX, which is the lowest priority MX, but yeah, I get the picture. Thanks for the tip, I might give it a try.
