You've received some great suggestions how to handle the reverse DNS issue,
which I agree with, is that you must contact the ISP who owns the IP
Regarding your paragrpaph above, you are saying that you are using the ISP's
DNS adresses on your SBS? Is the server configured with two NICs? You should
really set both NICs to the SBS IP address itself as the only DNS IP
address, and allow your own DNS server to resolve outside names. Configure a
Forwarder in DNS. The following will help explain it, and applied to SBS.
