I have to choose between three products for Virus Protection and SPAM Control.
Option one is to go with GFI.
Option two is to go with Symantec Mail security and SMTP Gateway.
Option three is to go with Postini (http://www.postini.com
Can an expert help me out keeping in mind the best performance and cost effectiveness?
If there are any known issues with any of them please let me know, because I have our Exchange 2003 installed on Clustered Nodes.
Thanks a lot in advance.
