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.
