possible to use cpanel just to filter mail for another email server?

Just a thought. The filtering isnt working so well on another email server.

How could one setup a domain just to filter email for another email server?

It is possible to have mail filtered and then pushed to another server. The solution I have in mind requires root access and some modifications to the Exim configuration, though.

Thank you for your response. I do have root access.

basically we had surbl filtering which worked better than anything else setup on the windows email servers and would like to use the surbl filter built in into spam assassin until we get the windows server fixed.

You should be able to achieve that by adding this directive in the ROUTERS CONFIGURATION section:

smart_host_remote_domain:
  driver = manualroute
  route_list = remote_domain 123.123.123.123
  transport = remote_smtp

"remote_domain" is the domain on the other server
"123.123.123.123" is the IP address of the server that handles mail for the remote domain

I believe this will work if you have SpamAssassin checking mail at the SMTP session level and not when the message is actually accepted.
