I have been using the OpenDNS basic package and implementation was initiated to stop the use of gmail and gmail chat and other web based mail and chat services. The service works great with one issue. If mail is sent to any of the .hotmail or .gmail address that may be legit for business purposes it is blocked or not resolved as exchange reports back. I would like to have my exchange server point to my ISP's DNS for the mail function and leave the OpenDNS as the DNS of choice on my network. Is this possible? I cant seem to find anything specific to this.
