Would someone be able to explain what "An iterative resolver has to be
able to deal with such responses" would mean.
What I am trying to do is turn off recusrion, so I just have an
advertising dns server for my domains, however some of my CNAME records
point to some external domains which are not resolving once I set
recursion off. I am running bind 9.2.4

You get a response with the answer section containing the CNAME but not
A record, and an rcode of zero. I wouldn't call that "a negative

It seems to me that you are still asking for "recursion sometimes"
rather than "recursion no".
