Question Secure webmail with LetsEncrypt

[Vito]

Hi all,
I've used the LetsEncrypt tool to generate a SSL Certificate for a domain hosted on my Vps powered by Onyx WebPro.
The website serve pages in https without problems but webmail (horde) still use a invalid certificate (said Chrome).
I've generated my certificate with the tool then via "SSL/TLS certificates" page I've selected the LetsEncrypt certificate and "Secure webmail"....

Unfortunately webmail cannot be secured by a Let's Encrypt certificate in a Plesk default installation.

But maybe you find valuable hints in this thread, how that limitation can be lifted:
