External Mail Problem

[durban56]

I setup an exchange server for the first and it works fine expect the I can't get emails from external account, but I can send mail internally and externally just fine. I have a domain name setup at Godaddy (xxxx.com) and the MX record on the server is mail.xxxx.com and at Godaddy is mail.xxxx.com.

I've open port 25 on my firewall, configure SMTP virtual server and the SMTP connector on the exchange server.

Any HELP!!! would be most appreciated.

P.S. My internet service is with AT&T w/ 5 static ips.

Have you natted the external IP address of your mailserver to the server's internal IP address, on the firewall?

You say you have "MX record on the server is mail.xxxx.com" - Your MX record needs to be published by your ISP, rather thjan something you do on your server. Give your ISP a ring.

Your MX record needs to be published by your ISP

Actually, it needs to be set by whoever handles your public DNS. Reverse DNS gets published by the ISP.
