You may wish to check the source port which your DNS servers are using to perform lookups. I've had a situation recently where someone was unable to send me mail. Upon investigation, I found that my name servers couldn't resolve his domain, but plain 'dig' on the same box could.
I've come across ISPs who think they should block DNS requests from certain _source_ ports to "improve" their security, which may explain what you're seeing.
If this is the case, I suggest Adrian finds a better ISP.
