it is a best practice to separate authoritative and recursive servers.
why?
e.g. a small isp has a hundred auth zones (secondaried far away and off-net, of course) and runs cache. why should they separate auth from cache?
I absolutely hate it when we run into an ISP that does this. We often have customers who are moving form some piss poor ISP and we "rescue" them. Then we find out that none of ISP A's customers (often including the customer who is moving their hosting) can get to the new site. Similarly we have occasionally seen customers who moved their hosting from us and we were still delivering mail locally. In order for the root servers to do their job the two really need to be separate.
