Microsoft Forefront Protection 2010 for Exchange Server (FPE) is the Edge Protection Server for a Microsoft Exchange organization 2010, where we can manage all the blocking of incoming mail in order to reject unwanted emails either by the condition we configure (Anti SPAM), since it provides us with 5 Anti-Antivirus Definition Engines from Different Manufacturers! We will also avoid anti-malware, We have the possibility of extensive configuration from a console that is easy to manage, We also have an information area that is also quite cool. And manageability with PowerShell, of course! This server must be the one that collects external mail and sends it to our organization, the ideal is to mount it on the server that is in the DMZ totally isolated from our organization and on the server with the Edge Transport function.
