If the box is the also the mx for the domain for which you want to do 
special routing, I believe there will be a problem if you apply that 
sender_based_routing patch. They cannot share the same mailertable 
lookups. Another table lookup needs to be defined for sender_based routing.

I will see if I can cook up something on a Centos 4 box.
