We are looking to upgrade our mail system to Exchange 2010. However, on install, it wants to join our AD domain. This means it has to be on the "Trusted" side of the firewall. But it cannot communicate with the internet unless it is in the "DMZ" of the
firewall, as we do not allow external traffic directly into our Trusted network. This is a requirement of PCI DSS for credit card processing. We do have an IIS 7 webserver in the DMZ. I was wondering if it could be used as a SMTP relay for the Exchange server?
Also, could Outlook Web Mail run on our IIS 7 webserver? If anyone could point me to whitepapers, best practices, etc. on how to set this up I would greatly appreciate it. Thank you!
