Cannot setup email service for my domain – “contains a protected word or inappropriate language”

Hi all,

I am trying to create a email service for my domain http://godeliver.co/ this will be a future delivery service, I have had no issues before while creating emails for my other domain, http://curtisboylan.com/ so I don't know why this one would be a issue.

The error I get is, This domain name can't be used because it contains a protected word or inappropriate language. Please contact support if you feel this is not the case.

Would anybody be able to help me out?

Thanks,

Curtis
