A post on a closed UK-academic-centric mailing list just now stated that 
hotmail seem to be blocking UDP queries with source port == 53.

My testing (using dig's "-b ipaddress#port" option) shows that they're 
refusing connections with privileged source ports. Anything >1023 gets a 
response.

If you have:

query-source address * port 53;  # or < 1024

Then comment it out and restart.
