[exim] Need some help modifying my router

Currently this router looks up in the directory server for the mailHost
and then sends the email to the relevant host. I am setting up a pilot
project and due to the lack of server resources I have to run the pilot
mail server on the same server but on a different IP. For safety sake I

have it on a different port. I would like to construct a router that
will check to see what the mailhost is and if the mailhost is the pilot
server the router will return the mailHost:port but if the mailhost is
anything else it will just do a standard smtp.

route_list = domain.com ${extract{mailhost}{$address_data}}
