No, just TLS. It will auto-fallback to port 25 if TLS is not available or used. Same for 587, which is much more important for clients, because so many large ISPs now block port 25 except for MX to MX traffic.
 
Remember, If your SmarterMail server supports TLS, you do not need an SSL certificate to enable TLS, but you do need an SSL certificate installed to enable TLS for clients.
