You will lose the network configuration of your Email Security appliance if you are reverting back after an 
AsyncOS for Email upgrade. The symptom is observed when you upgrade AsyncOS for Email from version 
7.5.2-203 to 7.6.3-019, and revert back to version 7.5.2-203.

When you upgrade to the latest version of AsyncOS for Email with expired Sophos Engine, an alert is sent 
to the user stating that the Sophos Engine has expired.

Workaround: You can ignore this alert. After the upgrade, auto-update will download and update the 
Sophos Engine.

Application fault occurs while adding a Recipient Address entry with more than 53 email addresses to 
Recipient Access Table (RAT) using GUI. 

Workaround: From the application fault screen, navigate back to the Add to Recipient Access Table page 
using the browser Back button, and perform the commit.
