Simply put, you can't. There is only one port 25 and mail servers
require you to be listening on it. If "scott" has it, "david" can't. NAT
sucks.
What I would recommend is turning your Exim box into an SMTP router,
something it's completely capable of. Add this code to the "routers"
section of your exim4.conf, where 192.168.1.2 is the IP of "david".
david:
driver = manualroute
transport = remote_smtp
domains = david.example.com
route_list = * 192.168.1.2
Make sure you've got DNSBLs set up on "scott" since "david" won't be
able to see the originating IP address.
