Exim redirect mail to another server?

Is there a setting / configuration change that can be made in Exim to redirect incoming mail for one domain to another mail server?

MX records currently point to my cPanel server so that the cPanel server provides spam filtering, etc. However, I want to configure Exim so that once mail arrives for a particular domain, messages are forwarded to the client's in-house e-mail server.

I know I can change MX records to point directly to their own server, but I'd like to relay through mine to provide e-mail / spam filtering service.

Can this be done with an Exim or cPanel hack / tweak?

 

I've thought of this approach (hiding the lower MX priority host behind a firewall and setting up rules to only allow relay forwarding from the host in question) but I'm looking for a solution that is configurable at the transport / Exim level on the host itself rather than through MX relaying.

Any ideas?

Thanks for your replies.

The artilce nickp666 provided is _exactly_ what I'm trying to achieve. I want to act as primary MX for a customers e-mail domain to provide virus and spam filtering and then push the mail directly to their non-MX-published Exchange host. thanks for the link - this is exactly what I was looking for.
