When trying to validate email address domains with Aspose.Network.Verify, I get the following result returned:
No available mail servers. Please check your DNS server configure.
This appears to be the case with all emails, even ones where the domain is obviously valid, such as hotmail.com yahooo.com telus.net gmail.com rogers.com etc.
What does this error mean, and how can this issue be resolved?
This issue appears to be an issue with the Aspose.Network.Verify Demo, as well. See below:
