Debian 8 Nginx Perfect server. I have: https://example.com working SSL with letsencrypt. https://server1.example.com:8081/squirrelmail SSL with self-signed... https://server1.example.com:8081/phpmyadmin SSL with self-signed... I want: Step 1. squirrelmail to load on https:// using letsencrypt. Like this: https://server1.example.com/squirrelmail (with letsencrypt) Step 2. https://clientwesbite1.com/squirrelmail (using letsencrypt) https://clientwebsite2.com/squirrelmail (using letsencrypt) All pulling the same original squirrelmail (https://server1.example.com/squirrelmail) (using letsencrypt) (not multiple installations) Same thing with Phpmyadmin, right? Or is that a whole different can of worms? How do I get to where I want to go? Fallback plan: If this is all too much trouble, please tell me how to get to "Step 1" at least. Thank you so much for your time. !
