SSL Certificates for domain mail in users accounts

[hockolicious]

Hello,

I would like to know how to set the use of an SSL certificate on an email domain so that the connection to the mail server is encrypted. If you use the Let's encrypt certificate generation system through DirectAdmin, this is not a problem. However, the problem arises when I insert my own LE certificate but generated elsewhere. Then the mail is not encrypted, which I check with this tool https://www.checktls.com/TestReceiver

I found some path with dovecot configuration in /etc/dovecot/conf/sni, but here I don't have configuration of domain which I manually uploaded the certificate instead of generating the system. It's a bug?

Okay, I forgot about setup CA Root Cert. Theard to close.
