I am running an exchange 2007 server an using the anti spam that is built in the exchange software. I am not very happy with it and am looking to replace it. What are the top 3-5 anti spam softwares out for exchange 2007. I ran Kaspersky Anti-Spam on my exchange 2003 server and it worked great. I was going to purchase it for my exchange 2007 but they said that they were still devolping it.
So I was wondering what everyone else is using and what is the top 5 price not being an issue.
