I am using the Aspose.Network.Verify.EmailValidator class to validate email addresses but it seems that for some domains it does not work correctly.
The result I get is DomainValidationFailed even though the domain is valid.
I have also verified these adresses at http://centralops.net/co/ (click Email Dossier) where both adresses are successfully validated (at least at domain level).
I don't know if it is related in any way, but I also get this problem when using the .NET Framework 2.0 built-in class IPHostEntry: ( System.Net.IPHostEntry iPHostEntry = System.Net.Dns.GetHostEntry(domain); )
Best regards, Anders
