issue with exchange server

So i'm running a box with the following at home.
win 2k configured as a dns, AD and exchange server with NAT.

I can receive emails fine, but I cannot send. I check exchange manager and they are stuck in the queue stating "the remote server did not respond to a connection attempt".

What gives? I've been racking my brains as I'm a somewhat newbie.

thanks!
 
Seems like a DNS issue to me. Can the server resolve the name of the remote domain you are trying to send to? Can you telnet to port 25 on the remote server from the Exchange server?
 
thats the thing i'm not sure what the remote server is, it can't send to hotmail or google, any messages get stuck in the queue.
 
Look up the MX records for a domain you're trying to send to and try to telnet to one of those servers on port 25 from the Exchange server.

Oh, also. You've probably got a dynamic IP address from your ISP and a lot of mail servers won't accept mail from those ranges these days.
 
Most likely, your ISP is blocking outgoing traffic on port 25. They force you to relay your e-mails through their SMTP servers to send anything out. This is done to block spam e-mails from being sent from a compromised user computer.
