cPanel Access Level
Root Administrator
I cannot setup this correctly.
My goal is at cpanel -> Email Accounts -> Set Up Mail Client for “[email protected]” at the Manual Settings area -> Secure SSL/TLS Settings
to have something like this

Username: [email protected]
Password: Use the email account’s password.
Incoming Server: clientdomain.gr
IMAP Port: 993
POP3 Port: 995
Outgoing Server: clientdomain.gr
SMTP Port: 465
Authentication is required for IMAP, POP3, and SMTP.

AND at autodiscovery have the same settings for each of my users. So for user 2 it would be clientdomain2.com user 3 clientdomain3.com etc

Currently while I see the above at cpanel, autodiscovery gives the servers hostname. server1.serverdomain.com.

How can autodiscovery have different clientdomain.com for each of my clients?

I believe the changes in cPanel version 60 will address this issue. Here's a quote from the cPanel 60 Release Notes regarding mail SNI functionality:

As of cPanel & WHM version 60, the Dovecot and Exim servers always enable Mail SNI. We removed all Mail SNI controls from user interfaces.

We also deprecated API functions or parameters within functions that control Mail SNI functionality, and we no longer use the mail_sni_mapfile.
This is discussed further on the following thread:

AutoSSL not so good for email

Thank you.
