I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Dr. KlahnPrincipal Software EngineerCommented:
The problem is that the email server is, in fact, not responding to requests.

The red section shows that the DNS lookup for the site is correct.

The purple section shows that the site is alive and TCP/IP is working, at least well enough to respond to ping.

The yellow section shows that there is nobody listening on the standard SMTP port, port 25.

If the host is linux, use netstat or sockstat to see if the host actually has port 25 open and connected to the mail process.  If the host is Windows, use TCP View to see if the host has port 25 open and connected to the mail process.

Once you know if port 25 is actually in use, it should be easier to figure out where the problem is.

Linux host. which option of netstat? Linux Fedora.
Dr. KlahnPrincipal Software EngineerCommented:
netstat or netstat --numeric-ports  -- either one will return the same information, the --numeric-ports option forces ports to be shown by number instead of name (if the port has a name)
