Checks whether the mechanism's target domain name, or a sub-domain thereof, is a "valid" domain name for the given request's IP address (see "ip_address" in Mail::SPF::Request), and returns true if it does, or false otherwise. See "valid_domain_for_ip_address" in Mail::SPF::Util for how domains are validated. See RFC 4408, 5.5, for the description of an equivalent algorithm.
