Version Release Notes

September 15, 2009

This release adds Sophos Secure PDF Exchange (SPX) capability to the Email Appliance. SPX provides the ability to easily send encrypted email messages without requiring recipients to have special configuration or client software. (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 and 7) and Mozilla Firefox (version 3) are the only supported browsers for this product release. However, the Email Appliance has been optimized for current-generation browsers, such as Internet Explorer 7 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.
