SSL errors on SMTP mail

I have this same issue as cyberpanel page facebook post every 3months when LE certificate expires. Even there is new certificate successfully issued on cyberpanel that error will come. I have had buy and run email debugger every 3month to solve this issue.
I suspect issue is that new certificate wont get updated automatically to /etc/pki/dovecot/private/dovecot.pem and /etc/pki/dovecot/certs/dovecot.pem but still have to confirm that when next time will get this issue.

Here is topic of this I created while ago. I also created bug report on Github which Usman closed as completed…
