Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

After you create a sending profile, you need to create an outgoing content filter that determines which 
email messages should be signed, encrypted, or signed and encrypted. The content filter scans outgoing 
email and determines if the message matches the conditions specified. Once the content filter determines 
a message matches the condition, the Email Security appliance signs, encrypts, or signs or encrypts the 
message.

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 (Final Action) 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
