My boss would like to turn on relaying on our one and only Exchange server for application purposes. He has proposed installing a secondary exchange server in our DMZ. I believe I can get away with only the DMZ IMS configured to transfer "inbound only", delivering messages by "forwarding all messages to host" (using the IP of the internal exchange server), and rerouting incoming SMTP mail to our email domains to "inbound". I would like to have as many other exchange functions as possible on the DMZ exchange server to be disabled or deleted (public information store). Is there anything else I need to do to get the DMZ exchange server to function simply as a '"forwarding" SMTP server?? Both are on Win2k servers, running 5.5 Enterprise, and internally we have a NT 4 domain.
