upgrade from Plesk v17.8.8 to v18.8.9 and renew or edit ssl certificates used to secure the mail server .
I haven't tried to replace the SSL/TLS certificate on another Plesk server but this issue already happened on two servers just after the upgrade.
ACTUAL RESULT:I haven't tried to replace the SSL/TLS certificate on another Plesk server but this issue already happened on two servers just after the upgrade.
No error into the Plesk interface, but dovecot.pem and postfix.pem are empty and mail server isn't availalble
EXPECTED RESULT:Certificates set into the Plesk interface are added to the mail server configuration
ANY ADDITIONAL INFORMATION:Issue can be fixed by downloading letsencrypt SSL certificate from Plesk and by putting is content into dovecot.pem and postfix.pem.
