Does it extend to cover Postfix TLS encryption?

Alright, I'm in the process of transitioning from an EFA3 setup to EFA4. With this upgrade, I have the option to use Let's Encrypt for certification. However, I'm wondering: Does this certificate apply solely to the httpd daemon, or does it extend to cover Postfix TLS encryption as well? Currently, my EFA3 system is equipped with a valid SSL certificate. Yet, I'm uncertain whether it's utilized for TLS encryption or strictly for the web interface.

Yes, when you enable Let's Encrypt it will ask you if you want to use it for postfix and you can decide.
