dig is a very comprehensive utility

All your DNS queries can be done using dig, but is available on Linux, if you are using it.

for doing MX record lookup do

dig mx

for querying a specific server, say, for this entry you can do

for reverse lookup
dig -x

the domain has to be internal if you need to do that scan , if it is public domain then you have to scan for the block range and do reverse lookup on each ip .  you can get block info and any registred dns entries on

In addition, you can use whois to look at the DNS registry information.

From there you can find who the registrar is, and hopefully administrative and technical contact of the domain.   That will hopefully help get contact info for the domain.
