Cisco Cisco Email Security Appliance C380 릴리즈 노트

If you are switching from a physical appliance to a virtual appliance, you will need to convert your 
configuration file to an AsyncOS 8.0 virtual appliance configuration file. For information, see the 
Release Notes for Configuration Migration Tool 1.0 for Cisco Content Security Virtual Appliances. You 
can import the AsyncOS 8.0 virtual appliance configuration file into a virtual appliance running Cisco 
AsyncOS 8.0.2. 

Please contact Cisco TAC for information required to provision your virtual appliance. 

Please be aware of the following upgrade impacts:

For DKIM Authentication, Cisco currently supports version 8 of the Draft Specification of 
‘Authentication-Results:’ header.

For SPF/SIDF verification, the 

spf-passed

 rule is no longer available in content filters. To maintain 

backwards compatibility, the spf-passed content filter rule will be accepted from XML configuration 
files but it will be converted to the spf-status rule with corresponding arguments. spf-passed will be 
changed to spf-status == "Pass" and NOT spf-passed to spf-status != "Pass". You can, however, still 
use the spf-passed message filter.

Cisco does not generally support the backward compatibility of configuration files with previous major 
releases. Minor release support is provided. Configuration files from previous versions may work with 
later releases; however, they may require modification to load. Check with Cisco Customer Support if 
you have any questions about configuration file support. 

When you configure Cisco AsyncOS to use received headers, you can specify that the header reflects 
one of the following hostnames:

The hostname of the Virtual Gateway used for delivering the message

The hostname of the interface the message is received on
