Cisco Cisco Email Security Appliance C370D

In AsyncOS 7.1 adds the option of a No Password Required security level to 
encryption profiles. This is the lowest level of encrypted message security. The 
recipient does not need to enter a password to open the encrypted message, but the 
read receipts, Secure Reply, Secure Reply All, and Secure Message Forwarding 
features will be unavailable to prevent another email user from sending a message 
on behalf of the original recipient. 

AsyncOS 7.1 provides packet capture controls. The packet capture feature 
provides the ability to intercept and display TCP/IP and other packets being 
transmitted or received over the network to which the appliance is attached. This 
feature can help you debug the network setup and to discover what network traffic 
is reaching the appliance or leaving the appliance. A 

packetcapture

 command 

has also been added to the CLI.

AsyncOS 7.1 includes an enhancement to the Virus Outbreak Filters feature. If the 
appliance has the Virus Outbreak Filters feature and either the IronPort 
Anti-Spam or Intelligent Multi-Scan feature, the anti-spam filter scans every 
message released from the Outbreak quarantine based on the mail flow policy that 
applies to the message. A message released from the Outbreak quarantine may be 
sent to the IronPort Spam Quarantine if it discovered to be spam, suspected spam, 
or a marketing message.

AsyncOS 7.1 now allows you to suspend and resume message receiving and 
delivery in the GUI using the Shutdown/Suspend page (formerly the 
Shutdown/Reboot page) under the System Administration menu.
