I could really use some help with setting up an Exchange Server enviornment on my home network using GoDaddy and Exchange Server 2007. I currently have a domain that my lab enviornment is on (lab.net) through Active Directory and the DNS server role. How do I setup my Exchange server and email addresses to point to my GoDaddy name (sky-live.net). I have only run the default setup configurations for my Exchange Server 2007 server and everything is setup. I currently use dydns.org to connect to my home's router IP because I do not currently have a static IP. Is it possible to setup my network so Exchange can send/receive emails over the internet from my (sky-live.net) GoDaddy domain? If so what is the best way to configure my settings to allow for this? I will need to setup the A record and MX records I'm assuming - but other than that I'm at a stand still. Any help would be greatly appreciated, Thanks!
