aaPanel_Kern already do. aapanel normal, just the mailserver seems error dan won't start (postfix, covedot). and the logs seems tricky. this one of my logs, i can't provide all my logs because of security reason:
dovecot[60415]: imap-login: Disconnected: Connection closed (no auth attempts in 0 secs): user=<>, rip=127.0.0.1, lip=127.0.0.1, TLS handshaking: Connection closed, session=<2vPx6JQlluN/AAAB>
that error appear after i change my hostname from mail.example.com to smtp.example.com. then after that error, i try to repair. now i can't even start the service.
