Hi @hexblot, thank you for bringing this up. In this case however, this should not be considered a product issue, because in such a configuration file there can be dozens of user defined settings. Like with MariaDB upgrades and even Nginx or Apache upgrades it is possible that with new versions, old configuration values won't work and need maintenance. You will also see this with Dovecot.

However, it is still a valuable post of yours, because other users who run into the same "NoCertRequest" issue will find it easier to resolve. So thank you again for posting this here.
