I wonder if I need Microsoft TMG forefront installed on EDGE Server.
I mean TMG or similar solutions.
In the past I have used GFI and installed it in on SMTP server in the DMZ to scan email for viruses before it get forwarded to the mailbox. that was in Exchange 2003.
Exchange 2010 has Edge Server, I am sure I can install GFI on it, but I am thinking what TMG forefront can do if I install it on the EDGE server.? or it has to be installed on a separate box on the DMZ where the Edge is installed?
I believe TMG forefront has anti virus/spam/malware functionalities as well as proxying.
