Problem with EmailValidator

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.

For instance and both fail Domain Validation.

I have also verified these adresses at (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

Thanks for your considering Aspose.

Our development team is working on this issue. I will get back to you shortly.

Have a good day.


It looks like the problem is caused by the network environment. It depends on the DNS, if we cannot resolve the domain host, we cannot do the validation.



Does this mean that you think the problem is in my network/dns configuration or maybe the configuration at the validated domain?
I am currently using another component to (successfully) do these kinds of checks.
The problem is the same on your online demo page (
(Where curiously enough the address fails with result: DomainValidationFailed)

Ps. If this can be solved I will buy the full package Aspose.Total asap ;)

Best regards,
