NetWrix Anti Spam for Exchange is a straight forward application for Microsoft Exchange Server or Microsoft Small Business Server (SBS). The product is very easy to install and run, works on the server, and doesn't require any client-side components.
All incoming messages are checked for known spam criteria, such as Spam URL Realtime Block Lists (SURBL) and keyword filtering, and then suspected e-mails are delivered to user's Junk E-mail folder.
Requirements:
· Internet Explorer 6.0
· .Net Framework 2.0 or later
