Turn off support for processing S/MIME-protected messages on the BlackBerry Enterprise Server
By default, the BlackBerry Enterprise Server can process S/MIME-protected messages. You can turn off support for processing S/MIME-protected messages if the BlackBerry Enterprise Server experiences issues when it processes S/MIME-protected messages or if your organization does not use S/MIME encryption.
- In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution topology > BlackBerry Domain > Component view > Email.
- Click the instance that you want to change.
- On the Messaging tab, click Edit instance.
- In the Security settings section, in the Turn on S/MIME message processing drop-down list, click False.
- Click Save All.
