Nope.

The sender's MTA (mail transport agent, I.E., Mailtraq 
<www.mailtraqna.com>, or Sendmail <www.sendmail.org>), looks up the MX 
record, which points to <mail.hosting.com>.  It looks up the A record for 
<mail.hosting.com>, which happens to be 64.29.16.2, and sends the mail 
there.  No other lookups, no loops.

BUT...

It only does all this if it can find the MX record.  It can't, because it 
can't find the nameserver, ns.hostinghq.com.  It seems there is NO A record 
for ns.hosting.com.

Do you have a "host" record set up at Network Solutions (or wherever your 
domain is registered)?  What does it point to?
