I installed and configured smtp module with proper details in drupal 7. I tried to send test the mail in windows 2012 server but am getting the below error.
SMTP -> ERROR:
Failed to connect to server:
getaddrinfofailed: This is usually a temporary error during hostname resolution and means that the local server did not receive a response from an authoritative server.
SMTP Error: Could not connect to SMTP host.
Unable to send e-mail. Contact the site administrator if the problem persists.
Same build is working fine in Windows XP, 07 and ubuntu environments.
Not able to find the root cause. Any suggestions are welcome.
