Bill, It depends on what your goals are? It is perfectly fine for your upstream provider to handle your DNS. However, I recommend not using your upstream provider for your mail server when doing spam checking. By having a local DNS server on the same locally connected network you will always gain a performance advantage rather than pushing queries upstream.
