Fixed: Multipart/Alternative Messages Result in Double DLP Score.
Previously, when RSA Email DLP scanned a multipart/alternative type message, such
as HTML messages with a alternative/plain text part, the system combined the
classifier scores of both parts of the message to create the DLP score. This could result
in a message that should have a “low severity” score to be rated as high or medium
severity. This issue has been resolved.

Fixed: App Fault Occurs After Appliance with Centralized Reporting Enabled
Starts Up.

When the Email Security appliance starts up, it performs a scan for corrupted files.
Previously, if the appliance had centralized reporting enabled, it was possible for an

deleting them. This issue has been resolved. The corruption scan no longer deletes
these timestamp files.

incorrectly due to the filename being composed of multiple words. The decoded
filename would contain an extra space. This could result in applications being unable
to open the file. The filename now decodes correctly.
