Hi All,
My problem is solved. Just wanted to inform that the problem was: "SMTP Relay was not enabled for our TEST and DEV servers on the SMTP HOST". requested them to enable it and it works great...!!!

Thanks all for your help!!!

The error message is actually quite informative. That server is not answering on port 25.
You need to contact that host's admin and see if they support SMTP input, and if so, do they require TLS, SSH, etc.

Its not a programming error, its an admin/usage issue



Thanks for your reply Farrell..!
Pat Farrell: The scenario is like, we use the same smtp host in our all three env's (DEV, TEST, PROD). This program runs FINE in Production servers but not in others..
so can it be a problem with the smtp host server or DEV and TEST servers ?
i mean should contact the team which supports smtp host or DEV/TEST servers ?

I tried the telnet stuff and it is connecting. but my application is not working. I cannot get the IP address. The name is correct though!!



try the following to get the IP address

ping <your_machine_name>

The response will have something like
Pinging with x bytes <your_machine_name> [your_IP]
Now use your_IP



Hi even i am facing the same problem, even if i replace HostName with the IP of the server , i am getting the same error.
