Debugging Mail Flow Using Test Messages: Trace
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.
See Anti-Spam.
Anti-Virus 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
returned is printed. If the Cisco appliance is configured to “clean”
infected messages, that information is noted. If 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-virus scanning is unavailable on the
system. If anti-virus scanning is available but has not been enabled
with a feature key, that information is also printed in this section.
See the Anti-Virus.
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.
See Content Filters.
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.
See Outbreak Filters.
