PORTS cannot be shared on the same IP ADDRESS.
So long as you setup SmarterMail on a separate IP address, you should be able to make it all work together.
Remember, whether you have a public IP address on the SBS server, or you are running a STATIC DHCP address and using NAT and mapping to a public IP address via your router or firewall, you must have a separate PUBLIC IP address as well.
