So I'm very new to Virualmin, and am having a problem.
I've been able to get SSL certificates from Let's Encrypt and with some trouble have been able to get it to work for the web server (It was a pain getting the ones for Webmin to work), but for the life of my I can't get my email clients to connect to the server and I think it's due to an SSL issue.
I'm getting a little mixed up because I had a VPS that had Virtualmin but I decided to try cPanel (which works perfectly, but not worth $20 a month to me). I've left it, but I ended up buying another VPS for 1 month just to try Virtualmin again before deleting cPanel. When I try to use openssl s_client on port 143 and 587 it returns no SSL certificate at all.
The best I can find is someone said to copy the certificate into Postfix and Dovecot, but no explanation on how to do that so I'm wondering if someone could explain how.
Thanks in advance!
