From your descriptive message, I am going to have to assume a few things, like is Exchange installed correctly, or is DNS setup correctly, or are there any firewall issues... Make sure the following work in this order: - Make sure TCP/IP is installed on your exchange server. - Test to see if your exchange server surf the internet. - Make sure that any firewall is allowing port 25 thru in both directions. Also, if you are behind a proxy server, make sure that is setup correctly. - Can you connect to the internet on any port number from your exchange server (try this cmd: "telnet smtp-gw-4.msn.com 25" and see if you get a 220 response - if not, then you probably cannot connect to msn.com's mail server to send a user there e-mail.) - On a computer that is on the same network as your exchange server, what happens if you do a "telnet <ip addy of exch server> 25" - that SHOULD work. If it doesn't, then you have issues with your exchange server and SMTP. - I am going to assume that your external DNS is setup correctly and working fine. Then have a friend try the same command as above, except replace the "smtp-gw-4.msn.com" with your FQDN for your mail server. For instance, if your mail server is mail.domain.com, then your friend would need to type "telnet mail.domain.com 25" from a computer that can fully see the internet. - Once you get to the point where your exchange server is responding to an external request for SMTP, then you need to make sure you have a place for a user's e-mail to go. See if your friend can send a message to administrator@xxxxxxxxxx (again, assuming the MX record for your DNS is working properly) - connect to your exchange server with Outlook, and test. If things are still not working, e-mail us back, but tell us what DOES work, as well as what DOESN'T work, and any steps you may have tried.
