Enable TLS encryption with a backup method

If you select TLS for message encryption, you can designate another encryption option as a backup method in case the TLS connection fails. Specifying a backup option allows you a second opportunity for message encryption in the event of an unsuccessful TLS connection. If both the TLS and backup connections fail, the message is sent to a delayed message queue for a later connection attempt.

Steps

  1. Navigate to the page Settings > Inbound/Outbound > Encryption.
  2. From the pull-down menu Encryption method, select Transport Layer Security (TLS).
  3. From TLS Encryption Backup Options, select one of the following options:
    • Use Forcepoint Email Encryption as backup encryption method

      This option is available only if your subscription includes the Forcepoint Email Security - Encryption Module.

    • Use third-party application as backup encryption method
    • Use secure message delivery as backup encryption method

      Additional options display according to your selection.

  4. Configure the settings for the selected backup method.
    See Third-party encryption application and Secure Message Delivery.
  5. Click OK.
    The settings are saved.
