Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Create a content filter to sign, encrypt, or sign and encrypt a message on delivery, which means that the 
message continues to the next stage of processing, and when all processing is complete, the message is 
signed, encrypted, or signed and encrypted, and delivered.

Understand the concept of building conditions for content filters. See 

.

Go to Mail Policies > Outgoing Content Filters.

In the Filters section, click Add Filter.

In the Conditions section, click Add Condition.

Add a condition to filter the messages that you want to sign, encrypt, or sign and encrypt. For example, 
to encrypt sensitive material, you might add a condition that identifies messages containing particular 
words or phrases, such as “Confidential,” in the subject or body.

Click OK.

In the Actions section, click Add Action.

Select S/MIME Sign/Encrypt on Delivery from the Add Action list.

Select the sending profile to associate with the content filter.

Click OK.

Submit and commit your changes.

After you add the content filter, you need to add the filter to an outgoing mail policy. You may want to 
enable the content filter on the default policy, or you may choose to apply the filter to a specific mail 
policy, depending on your organization’s needs. For information about working with mail policies, see
