Unable to open port 993 on my Ubuntu server

I needed to setup a mail server so I decided to read this tutorial and configure it.

I have double-checked everything on it and made sure that I’m following the tutorial as shown above, but I’m having a few issues.

When I try to check port 993 it says connection refused.

telnet 993

Replacing with my domain, this was my result.

telnet: Unable to connect to remote host: connection refused

Thunderbird was able to find all of my settings but I still wasn’t able to connect to my own mail :(

This is what thunderbird says that it found settings to.

But I cannot connect with the password I put on the email account itself.
