Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

has also been added to the CLI. For more information, see the “Common 
Administrative Tasks” chapter in the Cisco IronPort AsyncOS for Email Daily 
Management Guide.

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. See the 
“Common Administrative Tasks” chapter in the Cisco IronPort AsyncOS for 
Email Daily Management Guide for more information.

The 

signed-certificate

 rule selects those S/MIME messages where the X.509 

certificate issuer or message signer matches the given regular expression. This 
rule only supports X.509 certificates. See the “Using Message Filters to Enforce 
Email Policies” chapter of the Cisco IronPort AsyncOS for Email Advanced 
Configuration Guide for more information.
