how to obtain MX records for a domain

[Stefan Puiu]

Well,=20

in the queryNameServers() function you have the actual query code,
just find the line where the query is made (the res_mkquery() call)
and replace ns_t_soa with ns_t_mx. Some of the checks relevant for SOA
don't make sense for MX records, like making sure you get only one
record.
