you need to change this in the settings..

Go to Security > SSL/TLS Certificates > Secure Server services Button on the right... Then select the Lets Encrypt instead of the self-signed Cert!

Have fun !

Hello,

the server hostname already resolves to your server? This is mandatory for receiving a Let's Encrypt Certificate for server hostname.

Make sure, your mail client is using vps.bluecrystaleshop.com as mx server, not mail.vps.bluecrystaleshop.com or others.

(E.g. a test via https://www.checktls.com/TestReceiver seems correct.)
