[exim] second mail server

hi to all,

here is my problem:
                                           |
                                           |
                                      [Internet]
                                           |
                                           |
                                       [Firewall]
                                           |
                                           |
                                     [10.0.0.1mail-server-1, Exim 4] 
-----??-----> [10.0.0.2mail-server-2, No Exim]
                                           |                           
                                                           |
                                           |                           
                                                           |
                                       [LAN 1]                           
                                         [LAN 2]

I want to redirect (for now) just one email account of mail server1 to
mail server 2.
How can I do it ?
I tried this in my exim.conf :
...
#test:
# driver = manualroute
# transport = remote_smtp
# local_parts = joe.deep
# route_list = * mail-server-2

It didn't work... :(

someone can help me out?

thanks
