Appendix C      Example of Mail Policies and Content Filters
  Overview of Incoming Mail Policies
Bouncing Messages Sent to a Former Employee
The third content filter example uses one condition and two actions.
Procedure 
Step 1
Click the Add Filter button. 
Step 2
In the Name: field, type 
ex_employee
 as the name of the new filter. 
Step 3
Click the Editable By (Roles) link, select the Policy Administrator and click OK.
Step 4
In the Description: field, type the description. For example: 
bounce messages intended for Doug
.
Step 5
Click Add Condition.
Step 6
Select Envelope Recipient.
Step 7
For the envelope recipient, select 
Begins with
, and type 
doug@
.
Step 8
Click OK
The Content Filters page refreshes to show the condition added. Note that you could create an LDAP 
directory containing the email addresses of former employees. As ex-employees are added to that 
directory, this content filter would be dynamically updated. 
Step 9
Click Add Action.
Step 10
Select Notify.
Step 11
Select the checkbox for Sender and, in the Subject field, type
 
message bounced for ex-employee of 
example.com
.
Step 12
In the Use template section, select a notification template. 
Note
Some sections of the content filter rule builder will not appear in the user interface if the resource 
has not been preconfigured. For example, content dictionaries, notification templates, and 
message disclaimers will not appear as options if they have not been configured previously via 
the Mail Policies > Dictionaries page (or the 
dictionaryconfig
 command in the CLI). For more 
information about creating dictionaries, see 
Step 13
Click OK
The Add Content Filters page shows the action added. 
Step 14
Click Add Action.
Step 15
Select Bounce (Final Action) and click OK.
You can only specify one final action for a content filter. If you try to attempt to add more than one 
final action, the GUI displays an error. 
Adding this action may will cause senders of messages to this ex-employee to potentially receive 
two messages: one for the notification template, and one for the bounce notification template.
Step 16
Submit and commit your changes.
