The MX rule of 974 is perfectly reasonable to apply to IPv4
and IPv6.


RFC 974 also requires the use of a WKS record to verify that
the IPN address has a MTA running on it.

Please read RFC 1123 (section numbers mentioned in an earlier
note).  Use of WKS was explicitly deprecated; the MX rule was
not changed.
