Hello everyone, since i'm trying to set up a Let's Encrypt SSL cert, i've been experimenting some issues.

When i join my domain (http://xumail.us/mail with the Let's Encrypt SSL cert installed) it says that the server refused the connection, and i don't know why.

I followed everything that says in this tutorial: http://www.dsp3.org/integrating-lets-en … -iredmail/

Thanks!
