  Policy Enforcement
Creating an Incoming Mail Policy to Drop Spam Messages and Archive Suspected Spam Messages
In this example, the 
policyconfig -> edit ->
 
antispam
 subcommand is used to edit the Anti-Spam 
settings for the default incoming mail policy. (Note that this same configuration is available in the GUI 
from the Email Security Manager feature.)
First, messages positively identified as spam are chosen not to be archived; they will be dropped. 
Messages that are suspected to be spam are chosen to be archived. They will also be sent to the Spam 
Quarantine installed on the server named 
quarantine.example.com
. The text 
[quarantined: 
possible spam]
 is prepended to the subject line and a special header of 
X-quarantined: true
 is 
configured to be added to these suspect messages. In this scenario, Administrators and end-users can 
check the quarantine for false positives, and an administrator can adjust, if necessary, the suspected 
spam threshold.
Finally, the changes are committed.
