How can I configure an access-list to permit Exchange Server 2000 -
client communication in my backup interface?

You will need to force Exchange to use static port numbers for client/server communication instead of dynamically assigned ones;

Then create an access list to permit this traffic (matching the addresses for your network and the static ports you selected) and then apply the access list to the interface.
