[exim] redirect mails to another server

Hi,

How can I use exim like gateway, I have two mail
servers and I need to redirect all mail trafic of the
domain1 to the server1 and domain2 to the server2.

And what's up if I want to receive a mail from
specialuser@domain1
directly on the second server on specialuser@domain2
account, is it posible?

Thanks
Paul Aguirre
