[Dnsmasq-discuss] MX forwarding

[Gene Czarcinski]

The patch below has been tested and returns NXDOMAIN for A and AAAA 
plain-name queries (which stops /usr/bin/host) from doing an MX query 
(domain-needed is specified).  But a "host -t DS com" and "host -t DS 
org" returns the expected info.

A really simple patch:
