Just in general terms:
1. Choose a public IP (real IP) and designate that for email. Lets say this is 1.1.1.1
2. In your public DNS provider, go to your domain and create a new MX record with priority 10 and point it to the DNS name of your 3rd party filtering company
3. In your 3rd party filtering company, set your inbound and outbound mail servers to point to 1.1.1.1
4. If you have a firewall on the external interface before the router, accept only traffic from the DNS name of the 3rd party filter to 1.1.1.1 on port 25
5. On your router make the tranlation rule for all port 25 (SMTP) traffic for 1.1.1.1 to your internal mail server address...lets say 192.168.1.10
6. Internal DNS should have everything point to the internal address
7. Send connector should point to the 3rd party mail server
8. Receive connector should be set to anonymous and receive email from the 3rd party.
