Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

Select the encryption profile to associate with the content filter.

The encryption profile specifies settings about the key server to use, levels of 
security, formatting of the message envelope, and other message settings. 
When you associate an encryption profile with the content filter, the content 
filter uses these stored settings to encrypt messages.

Enter a subject for the message.

Click OK.

After you add the encrypt action, click Submit.

Commit your changes.

Once 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 

AsyncOS enables you to add encryption settings to a message by inserting an 
SMTP header into a message using either a content filter or a message filter. The 
encryption header can override the encryption settings defined in the associated 
encryption profile, and it can apply specified encryption features to messages.

To add an encryption header to a message by using a content filter, add the Add 
Header filter action to the content filter, and enter the encryption header and its 
value. For example, if you want a Registered Envelope to expire in 24 hours after 
you send it, type 

X-PostX-ExpirationDate

 as the header name and 

+24:00:00

 

as the header value.
