Setting the encryption gateway options

Perform the following steps in the Email Security module to configure the encryption gateway options:

Steps

  1. On the page Settings > Inbound/Outbound > Encryption, from the pull-down menu Encryption method, select Third-party application.
  2. In the Add Encryption Server area, enter the IP address (or hostname) and port of your encryption gateway server.
  3. Enable the MX lookup function; mark the check box Enable MX lookup.
    Important:

    If you entered an IP address in the previous step, the MX lookup option is not available.

    If you entered a hostname in the previous step, this option is available.

    • Mark the check box Enable MX lookup for encrypted message routing based on the hostname MX record.

    • If you do not mark this check box, encrypted message routing is based on the hostname A record.

  4. Click the arrow button to add this information to the Encryption Server List.
  5. In the pull-down menu Encrypted IP address group, ensure that Encryption Gateway is displayed.

    This selection helps to prevent the creation of an email routing loop.

  6. Ensure that users present credentials to view encrypted mail, mark the check box Require authentication and supply the desired user name and password in the appropriate fields.

    Authentication must be supported and configured on your encryption server to use this function.

  7. In the field Encryption X-header, enter the header name and value that you created in your third-party application using the following format: 
    header name:value
  8. In the field Encryption success X-header, enter the header name and value that you created in your third-party application for the encryption success header using the format shown in the previous step.
  9. In the field Encryption failure X-header, enter the header name and value that you created in your third-party application for the encryption failure header using the format shown in step 7.
  10. Click OK.
