Assuming we are discussing SBS with Exchange on site, you do not configure anything locally to have internet email delivered to your Exchange server except the wizards in the SBS Console.
MX records are maintained by your public DNS host, which may be the same as your domain registrar but don't have to be. You setup an A record that points to your public (preferably static) IP address, and then an MX record that points to the A
record. Note that some public DNS hosts have changed their interface to allow/require that an IP be used in the setting for the MX record, but this is just for the users convenience).
Once the wizards have been run, the public MX records established at your DNS host, you need to contact your ISP and insure they have set an reverse lookup records, aka "pointer" record, for you domain name and IP.
