My problem appears to be with the fact that I have "HasWildcardMX" set.
When the reverse lookup is done, MX records are not used because 
there'll be a match against a domain in my search list (*.demon.co.uk).
If I turn "HasWildcardMX" off, then all domains match"

How might I find out if there is a wildcard MX record from the
programming point of view?
