This domain is extremely misconfigured. Have  a look at results of an MX
lookup with this DNS checker tool:

http://www.squish.net/dnscheck/

According to this tool 100% of queries will end up failed. 92.5% of them
are due to  too may nested queries,  and the rest are  due to nameserver
loops. Have you notified newcastle.edu.au's hostmaster?

Check this domain  with the above mentioned tool as  well. Only 50.7% of
the queries will  ever result in a successful result.  The rest fail due
to  nested  query  problems  and nameserver  loops.  Have  you  notified
deloitte.com.au's hostmaster?

That doesn't really prove much. Even dnscache eventually gives an answer
for these domains.

It isn't just apparent, it is blatant.

Have you tried contacting these  problem domain's owners?
