Now there is it:
Secure SSL/TLS Settings
(Recommended)
Username: [email protected]
Password: Use the email account’s password.
Incoming Server: mail.site.com

IMAP Port: 993
POP3 Port: 995

Outgoing Server: mail.domain.com

SMTP Port: 465

Authentication is required for IMAP, POP3, and SMTP.

So I want change this mail.domain.com to mail.website.com address. But I didn't find concrete help.
Now there is two server. The website.com is on a webhosting. The nameserver(ns1.website.com,ns2.website.com) is on a server. The all website is work in this server, this is ok. The smtp mail is mail.site.com and not mail.website.com.

Hello

When using the "Configure Email Client" option within cPanel, the SSL hostname values come from the name of the certificate for the respective service in:

"WHM >> Service Configuration >> Manage Service SSL Certificates"

It's not possible to install a separate certificate on each service at this time. However, feel free to vote and add your input to the feature request for this at:

SSL Certificate Per Domain On All Services

Thank you.
