Hi Mohammad,

Have a look at http://www.faqs.org/rfcs/rfc1912.html Section 2.4. A
CNAME can't co-exist with other data. So if you take out the MX record
for lists.tag-legal.com. you should be good to go.

The resolver will then see that lists.tag-legal.com. is pointing at
lists.tagorg.com. and check the MX records on lists.tagorg.com.

Niall.
