A system that I am setting up has a DMZ and they want to use Exchange 2K functionality and have their own mail server. A colleague has suggested, locating the Exchange server in the DMZ and allowing the clients to access the server through the Internal firewall. The Domain controller (All 2K) is located on the internal network and I would like all accounts to be centrally administered. I also want no connections initiated from the DMZ into the internal network.
If I use a front end / back end server situation I will need to punch a few holes though the firewall.
Can I use a Linux server running send mail/qmail/whatever to pickup the mail and the internal exchange server to retrieve it? Thus elimination the need to open up a hole from the DMZ to the internal network?
Does an anyone have any ideas or suggestions???
