The first thing I would do is check the results of the DNS scan here
(http://www.dnscog.com/report/thought.org) and fix all of the listed
problems.  Keep iterating until the report is clean, or at least doesn't
have any red flags on it.  I've used this service successfully for a
while now to debug DNS problems.

Hope that helps,
