Cannot make certificate get valid on mail server

My domain is:

The operating system my web server runs on is (include version): CentOs
I can login to a root shell on my machine.

I'm using plesk 18.0.49 to manage my site

I'have done with webmail but seem not works with mail server and certificate ( ssl or startsl )

How i can fix it?

Hello @Wing, welcome to the Let's Encrypt community. :slightly_smiling_face:

I suggest first starting with Let's Debug when diagnosing why one is having troubles getting a certificate issued form Let's Encrypt.

Here is a list of issued certificates |, the latest being 2023-01-04.

That sounds like a mail server configuration.
Check the documentation on that software.
