When I was searching the internet for some mail server program, I found this software called Personal Mail Server Pro in the search results. I could not get much information about the same on the internet, so I am seeking help here. Basically, I need to know what is Personal Mail Server Pro. What are the operating systems that it supports? As I am using Windows Vista operating system with 2 GB RAM and Core2Duo processor, will it run fine in my system? Please provide the information immediately.
