Anti-Spam 

This section notes messages that are not flagged to be processed by 
anti-spam scanning. If messages are to be processed by anti-spam 
scanning for the listener, the message is processed and the verdict 
returned is printed. If the Cisco appliance is configured to bounce or 
drop the messages based on the verdict, that information is printed and 
the 

trace

 command processing stops. 

Note: This step is skipped if anti-spam scanning is unavailable on the 
system. If anti-spam scanning is available but has not been enabled 
with a feature key, that information is also printed in this section.

This section notes messages that are not flagged to be processed by 
anti-virus scanning. If messages are to be processed by anti-virus 
scanning for the listener, the message is processed and the verdict

infected messages, that information is noted. If configured to bounce 
or drop the messages based on the verdict, that information is printed 
and the

Content Filters Processing

All content filters that are enabled on the system are evaluated by the 
test message at this point. For each filter, the rule is evaluated, and if 
the end result is “true,” each of the actions in that filter are then 
performed in sequence. A filter may contain other filters as an action, 
and the nesting of filters is unlimited. The results of the content filters, 
processed in order, are printed in this section.

Outbreak Filters Processing

This section notes that messages that contain attachments are to 
bypass the Outbreak Filters feature. If messages are to be processed by 
Outbreak Filters for the recipient, the message is processed and the 
evaluation. If the appliance is configured to quarantine, bounce, or 
drop the messages based on the verdict, that information is printed and 
the processing stops.
