Unable to receive email on Exchange Server
I have setup Exchange server in my organization. I can send Receive mail on intranet. Can send mail to outside domains like yahoo, gmail etc. But unable receive mails from outside that is from internet.
I have domain with godaddy and created a MX record pointing to my public ip of my exchange server.

=======================
I agree with the MX record - it should point to an A record.
Other things to check: Are you sure that your server has port 25 publicly exposed via the mapped IP and protected by a firewall? You DO have a firewall right? Be sure that the server is also configured to relay e-mail from ONLY internal sources and does not permit relay from the outside world. Test that port 25 is open to the public by simply telnetting to port 25 on the public IP address of your mail server. This will quickly show you if the networking portion is working properly.
