Cisco offers the following resources to learn more about your appliance: 

You can access the online help version of this user guide directly from the appliance GUI by clicking 
Help and Support in the upper-right corner. 

Documentation for all Cisco Content Security products is available from:

Using From Header for 
DKIM Signing

You can now use the DKIM Global Settings (Mail Policies > Signing 
Profiles) to choose whether to use From header for DKIM signing. For 
DMARC verification of DKIM signed messages, you must use the From 
header during DKIM signing.

Duplicate Boundaries 
Verification

Cisco Email Security appliance can now detect messages with duplicate 
MIME boundaries and perform actions on them. 

Use the Duplicate Boundaries Verification content filter condition or the 

duplicate_boundaries

 message filter rule to detect messages with 

duplicate MIME boundaries.

See 

Message Filter Rule to 
Detect Malformed MIME 
Headers

You can now take actions on messages with malformed MIME headers 
using the new message filter rule: “

malformed-header

.” 

See 

CA Flag Check

You can now check whether the CA flag is set to TRUE on all the 
certificate authorities in the custom list. To be Common 
Criteria-compliant, all the trusted certificate authorities installed (System 
and Custom Lists) in your appliance must have the CA flag set to TRUE.

Use the 

certconfig

 > 

certauthority

 > 

custom

 > 

CHECK_CA_FLAG

 

command in the CLI.
