I've been having lots of trouble getting my server running properly. I thought if I setup a domain (lets call it example.com) that I could then use something like mail.example.com as the mail server. for that domain (using letsencrypt), but it's not working. The main server doesn't even have a running mail server with startls. The main ispconfig main panel does have a letsencrypt certificate but mail on the min server does not have encryption working. What do I need to do to make this work. I've purchased the manual but it isn't really helping me work through this. I'm hoping I can get help. Thanks
To set up a certificate for your mailserver, you can follow this guide: https://www.howtoforge.com/securing...server-with-a-valid-lets-encrypt-certificate/
