Question SSL Certificate Mailserver

[TELLO0815]

Hi all,

I use on my pleskserver linux 18.0.32 app. 15 domains and they have also different emails using the Plesk email server.

My question is to secure the email server with ssl. With let's encrypt I get sometimes certificate errors.

But I have for some domains ssl certificates. Lets say:
nicedomain.com
uglydomain.com

So can I use such a ssl certificate nicedomain.com for the email server or will this bring errors, if I connect for email with the domain uglydomain.com?

Thanks for help

OK - guess find the solution myself.
If I use one SSL from my domain, I just must use this domain for all emails to connect (Email Server).
