No googling necessary. Whoever handles the external DNS records for heltonindustries.com will do that for you. That's most likely going to be your ISP - what you want is a DNS PTR record that says that your public IP address has the name of your Exchange server, which will be name-of-your-exchange-server.heltonindustries.com.
Once that's done, someone out in the world who does a 'ping -a name-of-your-exchange-server.heltonindustries.com' will get back the public IP address that your Exchange server sends from.One other thing to check on (I haven't, you should) is to make sure that you have a valid MX record for your exchange server as well. Of course, this means that you must have a static public IP address, assigned by your ISP. If you have a dynamic IP address for your Exchange server, you *must* use your ISP's mail server as a smarthost.
