no we want to upgrade the front end server.  leave the backend as 2003 is this possible we have 2 servers one as front end and backend
You can have the Exchange 2007 as the front end and you can set it up using an example from this link.

Exchange 2007 no longer is just a front and backend scenario. exchange 2007 has five different roles.

See this example.

You can setup the Exchange 2007 server as the edge transport and hub transport so it can send the email to the backend. You can also utilize the anti-spam feature with the edge trasnport. Idealy it just depends how you want to set everything up. If you only setup those two roles for exchange 2007 you are not utilizing the full power and benefits of exchange 2007.
