Примечания к выпуску для Cisco Cisco Email Security Appliance C170

DKIM Signing of System 
Generated Messages

DKIM Signing of System Generated Messages option is now available 
under Mail Policies > Signing Profiles > DKIM Global Settings.

New Alert for Message 
Filter Crashes 

When a message filter crashes, the appliance sends a system alert with a 
critical severity.

Change in SPF 
Verification Content and 
Message Filter Behavior

If you have configured an SPF verification content or message filter rule 
without an SPF identity and if a message contains different SPF identities 
with different verdicts, the rule is triggered if one of the verdicts in the 
message matches the rule.

DKIM Signing-related 
Logging Changes 

If the log level is set to Trace, the mail log will now include additional 
log entries to identify errors that occur during the DKIM signing 
process. 

The mail log will now include two separate log entries for DKIM 
signing: one for displaying the signing profile that will be used for the 
signing and the other for the signing event.

AMP-related Mail Log 
and Message Tracking 
Changes

Prior to this release, if the threat verdict of a file is unknown, the verdict 
was shown as “clean” in the mail log and message tracking. 

After upgrading to this release, if the threat verdict of a file is unknown, 
the mail log and message tracking will show the verdict as “unknown.”
