Then just skip this domain verification step and advance to sender
verification, because there is (as Jeremy and Mike wrote) more logic
involved, than just checking the "existence" of a domain.

If the domain does not exist (is not registred), sender verification
fails, as it does if there is no MX/A record for the domain.
