CNAME record and a MX record in 8.2.3?

[Bill Larson]

I am assuming that the zone that this file is for is "wtul.fm".  If not,
everything that I say is most likely wrong.

What it sounds like you are asking is that http;//www.wtul.fm and 
http://wtul.fm both get redirected to the machine pulse.tcs.tulane.edu.

You CANNOT use a CNAME record to redirect traffic for "wtul.fm" to
"pulse.tcs.tulane.edu".  The basic rule is that the left hand side domain
name that is identified with a CNAME record cannot have any other DNS
information associated with it.  I.e., since "wtul.fm" has SOA and
NS records associated with it, you cannot have a CNAME record also.

The easiest solution is to have an "A" record for "wtul.fm" which 
has the sam IP address as "pulse.tcs.tulane.edu".  Using a CNAME
record for "www.wtul.fm" is completely correct.

You have an "A" record for "wtul.fm" which identifies "pulse.tcs.tulane.edu"
on the right hand side.  This line is commented out, so I don't know
if this is just a comment for yourself, but I hope so.  If you
were to uncomment this, you should receive an error when loading.
An "A" record must have an IP address on the right hand side.
