Encrypt email using a mail policy content rule

You can configure the Email Gateway to apply encryption if certain content is detected in an email message (for example, confidential material or a particular file type).

The following tutorial shows you how to encrypt email containing a specific word or phrase such as the name of a new product.

  1. Create a new lexical expression list called Product name that contains the word or phrase that you want to search for.

    For information about how to do this, see Example 4: Product Name - simple text entry in the Create a Lexical Expression topic.

  2. Create a new content rule called Detect product name that uses your new lexical expression list.

    • Point to the Policy tab.
    • Under Manage Policy Definition, click Content Rules.

    • Do one of the following:

      • On the Content Rules toolbar, click New.
      • In the Task panel, click New content rule.
    • In the Add a Content Rule dialog box, click Detect lexical expression.
    • In the Overview area, click Click here to change these settings.
    • In the Name box, type Detect product name.
    • Click Save.
    • In the Lexical Expression area, click Click here to change these settings.
    • In the Expression list list, click Product name.
    • Click Save.

  3. Set the disposal action for your new content rule to Deliver the message > Applying encryption endpoint policy.

    1. In the Disposal Action area, click Click here to change these settings.
    2. Make sure that Deliver the message is selected.
    3. Change as specified on the route to applying encryption endpoint policy.
    4. Click Save.
    5. Apply the configuration.

  4. Create one or more encryption endpoints to be applied to all recipients on the mail policy route.
