Thanks Gordon, I am using dnsmasq and was able to use the MX aliasing
feature to supply the cache with a decent MX record as you eluded to so
it is working now.

for the benefit of the list archives, what you are refering to above is
the nameservers returning bad data as below noting that the ns1 and ns2
are supplying the bad data?

thanks eveyone for your help!
