I have successfully set up my server to use letsencrypt SSL for HTTPS and for IMAP/POP3/SMTP AND I MUST SAY-- THIS IS AWESOME. Thank you! I did it following the how-to-forge along with this post to help setting up the email part: https://www.howtoforge.com/community/threads/letsencrypt-on-mail-server.73695/ Now-- I don't understand how to go about keeping my certs renewed? It seems there are two mechanisms going on here, something about a cron, and something about a built-in renewal feature of ISPconfig, and I am not sure if I need to do anything or not now. I want to keep the certificate renewed on this mail server for both http AND email! How do I ensure I have this renewal stuff properly setup? Thanks.
