Hi,
Be sure .CheckLiteralDomain is set to true. This will actually check the IP address of the domain for a mail server. Here is a little more info from the help doc:
http://aspnetmx.com/help/_3eo0xugdg.htm
I also verified the email address does validate correctly from the aspnetmx.com website. Here is the output. Let me know if you need anything else.
