Your original post made me believe you are running Windows CAS servers. 
Why not use Windows High Availability features to bind one address to both 
servers.   A colleague was setting up a HA cluster for Exchange and was 
explaining some of it to me.  IIRC, you point to one IP address, and it 
points to one server, if it goes down, the other picks up the load.  You 
have MX records point to both of them, the client access uses a different 
address than the SMTP process.  At least that's how I understood it. 
Sorry, I'm not an Exchange guru.
