If my domain is mydomain.com, what should my DNS settings look like on GoDaddy.com and on my DNS server internally?
- Do you really intend to use POP3 to download email from Exchange? Or will your Microsoft Outlook clients be connected directly to Exchange Server over a local area network (LAN)?
- If so, you will want to create two DNS records:
- HOST (A) record: Give it a name such as mail.yourdomain.com and point it to the IP address of your Exchange server. (Assuming that your Exchange is on a LAN with a private IP address, then the IP address that you will want to specify is the publicly accessible one that your firewall is using. It is also very helpful if your firewall has a static IP address. If not, then you should either change your Internet plan to provide a static IP address, or obtain software like DirectUpdate as a workaround).
- Mail Exchange (MX) record: This tells the world where to find your email server. Point the MX record to the host record that you created in the previous step. Give the MX record a "priority" setting such as 10 or 20. (The lower the number, the more precedence this record takes over other MX records).
- If you are running Windows SBS with Exchange Server on your LAN, and your Outlook clients use an Exchange-based profile instead of POP3, then you will not need to make any DNS changes in your Active Directory. SBS will handle all of that for you.
