Cisco Cisco Email Security Appliance C370D

This section describes the new features and enhancements added in the Cisco 
IronPort AsyncOS 7.1 for Email release.

AsyncOS 7.1 provides a browser-based DLP Assessment Wizard to guide you 
through the three-step process of configuring popular DLP policies and enabling 
them in the default outgoing mail policy.

AsyncOS 7.1 provides a number of enhancements to the TLS features on the 
Email Security appliance:

Certificates Management. You can use the GUI and CLI to add trusted 
public certificates and create a self-signed certificate. You can also use the 
appliance to generate a certificate signing request.

Previously, the Cisco Appliance Demo certificate became the default TLS certificate 
for LDAP, HTTPS, destination controls, and all listeners after upgrading the Email 
Security appliance to AsyncOS 7.1. This issue has been resolved. Custom certificates 
are not changed during the upgrade.

In AsyncOS 7.0 and 7.1, certain specific viral email attachments could cause delays 
in mail processing and queue backup issues, which could eventually lead to corruption 
of the email queue, if the appliance's mail policies used McAfee anti-virus scanning 
and the "Drop infected attachments if a virus is found and it could not be repair" 
option was enabled. This issue was resolved in AsyncOS 7.1.1.
