SPF should not do a lookup on "61.16.173.99" and then return
NXDOMAIN, but should simply not do a lookup on it at all (treat as
if absent from the list).
This means that SPF implementations would have to:
hints_numeric.ai_flags = AI_NUMERICHOST;
error = getaddrinfo (server, port_name, &hints_numeric, &res);
to test if the "name" is actually an IP address? Bad idea, IMHO. SPF
implementations should treat that MX as any other and then return
ERROR (it is an error to have a name which does not resolve on the RHS
of a MX).
I can see the overhead. Would you return NXDOMAIN, though?
