Limited release

July 22, 2020

This release resolves several issues. The appliance will not restart after this update.

You should also familiarize yourself with the known issues, since improper configuration of certain options may cause unexpected behavior.

Before you begin installing and configuring the Email Appliance, you should review the configuration directions.

Internet Explorer 7 and later, and Mozilla Firefox version 4.x and later, are the only supported browsers for this product release. However, the Email Appliance has been optimized for current-generation browsers. 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.
