GFI MailEssentials features not one, but two anti-spam engines to give administrators an ultra high spam capture rate out-of-the-box with minimal configuration. Incorporating multiple anti-spam modules and technologies, GFI MailEssentials not only delivers one of the highest spam capture rates in the industry, over 99%, but it is also a market leader in reducing false positives.
