Re: Email server: security certificate for server is invalid or expired
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.)

Hello together
I have the same problem. I checked already the SSL/TLS Certificate config. Still the same problem.
Do you have a solution for this problem?
Thanks a lot for your help!
