Are you donating a MX or installing a honey pot? The error you describe could come up if you were installing a honey pot. If you're donating a domain, the check happens after the donation is complete (there's no check on the website to see if it's registered that I'm aware of). After you enter the subdomain you want to register it'll present you with instructions. It will then check if the underlying domain is registered and then if the MX of the subdomain has been setup pursuant to our instructions. If it's not setup correctly, the system will send you an email. Again, I'm not sure how you can be getting the error you're getting at the place you say you're getting it. Weird.
I'm not sure what's going wrong. Try it again. Make sure you're on the Donate an MX page, not the Install a Honey Pot page. If you continue to have problems, let us know.
