Chapter 11      Content Filters
  Filtering Messages Based on Content
Step 2
Click Add Filter
Step 3
Enter a name and description for the filter. 
Step 4
(X-REF) Click the Editable By (Roles) link, select the Policy Administrator and click OK.
Delegated administrators who belong to the Policy Administrator user role will be able to edit this 
content filter and use it in their mail policies.
Step 5
(Optional) Add a condition for triggering the filter.
a.
Click Add Condition.
b.
Select the condition type.
c.
Define the condition’s rules.
d.
Click OK.
e.
Repeat these steps for any additional conditions you want to add to the filter. When you define more 
than one condition for a content filter, you can define whether all of the defined actions (that is, a 
logical AND) or any of the defined actions (logical OR) need to apply in order for the content filter 
to be considered a match.
Note
If you do not add a condition, the appliance will perform the content filter’s action to any 
message that matches one of the mail policies associated with the filter.
Step 6
Add an action for the appliance to take on a message that matches the filter’s condition.
a.
Click Add Action.
b.
Select the action type.
c.
Define the action.
d.
Click OK.
e.
Repeat the previous steps for any additional actions you want the appliance to take.
f.
For multiple actions, arrange the actions in the order that you want the appliance to apply them to 
the message. There can only be one “final” action per filter, and AsyncOS automatically moves the 
final action to the end of the order.
Step 7
Submit and commit your changes.
