Does anyone know of a FREE tool or method to perform an MX record lookup from within KiXtart to supply an address to an application?

Microsoft's NSLOOKUP allows you to set a filter to do this, but not in a non-interactive mode.
How to obtain Internet Mail Exchanger records with the Nslookup.exe Utility

Example:
NSLOOKUP
[now puts you into an interactive mode]
set q=mx [now only queries mx records]
mymailserver.mycompany.com

Would come back with something similar to this:
Server: mydnsserver.mycompany.com
Address: 122.120.100.1

authoritative answer:
mymailserver.mycompany.com MX preference = 10, mail exchanger = server1.eastcoast.mycompany.com
mymailserver.mycompany.com MX preference = 0, mail exchanger = server1.westcoast.mycompany.com
mymailserver.mycompany.com MX preference = 0, mail exchanger = server2.westcoast.mycompany.com



What I'm attempting to do is use BLAT to send e-mail, but I want to have KiXtart check and verify first that the server is up and if not then check the next server in line
BLAT does not appear to natively support an MX record lookup so I want to attempt to have KiX support it for BLAT.

I've found tools to do it, but would prefer a free method or tool to do so. In my case I already know all the real names, so I could manually code it in KiXtart, but I would rather automate it so that in case a server is changed I don't have to modify my code, which is the purpose of having an MX record in the first place.

I'm sure Howard could supply an EXE using Perl to do this. Too bad Microsoft does not allow this in a non-interactive mode
