I just finished passing all my domains into https (thanks a lot let’s encrypt) and as everything goes well I would like to go further with a cerificat mail.
How do I add mail.example.com?
Can I use this certificate to encrypt data?
Thank you in advance for your help
I ran this command:certbot certonly --webroot
My operating system is (include version):debian 8
I can login to a root shell on my machine (yes or no, or I don’t know):yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):no
