[lug] DNS resolution woes

[Jeff Schroeder]

... So I have a Linux box (Red Hat 7.2) sitting in the midst of a 
corporate Windows environment.  The Linux box is tasked with sending 
mail (using Qmail) to the Windows mail server, for delivery to users in 
the company.  Everything is being done behind a firewall, so all IP's 
resolve to 192. addresses.

The problem is, the Windows DNS server being used by the Linux box is 
apparently messed up.  It isn't sending an MX record at all, so the 
mail can't go through (Qmail can't resolve the proper mail server).  I 
don't have control of the Windows machine, but the company sysadmin 
assures me he's set up the MX record appropriately.

When I run 'dig', I see the following (domain name changed to protect 
the innocent).  Note the "BADTYPE" line, with "unknown RR type".  Does 
anyone know what this means?  Has anyone seen this problem when using 
Windows DNS from a Linux platform?

TIA,
Jeff
