You must enable TLS for any listeners where you require encryption. You may want to enable TLS on 
listeners facing the Internet (that is, public listeners), but not for listeners for internal systems (that is, 
private listeners). Or, you may want to enable encryption for all listeners. 

You can specify the following settings for TLS on a listener. 

TLS is not allowed for incoming connections. No connections to the listener 
will require encrypted SMTP conversations. This is the default setting for all 
listeners you configure on the appliance.
