Version Release Notes

January 5, 2010

This release adds important new data leakage protection (DLP) capabilities to the Sophos Email Appliance. SophosLabs-managed Content Control Lists (CCLs), as well as custom lists, can be used to help control the flow of sensitive information. This can include financial information, content that contains confidential or personally sensitive information, or other material of a sensitive nature. (For more information on this new feature, see the Notable Changes.)

When this update is installed, the Email Appliance will reboot.

You should also familiarize yourself with the known issues listed below. Improper configuration of certain options may cause unexpected behavior.

Before you begin installing and configuring the Email Appliance for the first time, you should also review the configuration directions listed below.

Internet Explorer (versions 6, 7 and 8) and Mozilla Firefox (version 3.x) are the only supported browsers for this product release. However, the Email Appliance has been optimized for current-generation browsers, such as Internet Explorer 8 and Firefox 3. If you are using an older browser such as Internet Explorer 6 and experience performance issues, consider upgrading to a newer version of Internet Explorer, or to a recent version of Firefox.
