A manualroute router should enable you to get the messages across to
the correct server.
route-bounces:
driver = manualroute
domains = bounce.myhost.com
route_data = <IP address of server which should get the bounces>
transport = remote_smtp
It needs to go ahead of any other router which might handle the domain
in question.
