And if possible, how to disable statistics completely and safely? Without the "0" trick, that leads getting;

Hi!

you cannot disable the new stats, they are integral to how Dovecot works. If you disable access to the socket, you get the errors as you saw.

See https://doc.dovecot.org/configuration_manual/old_stats/, but keep in mind that all the settings should be prefixed with old_.

Also 2.4 will not have old_stats at all, so it is probably better to start using new metrics instead.

Thank you very much Mr. Aki for your quick and prompt reply! Got it.

Is my configuration properly aligned for new metrics? Is "service stats" block (which I assume it's new one) enough to enable new metrics?

Kindest Regards. Konstantin

having

service stats { }

does absolutely nothing useful.

service stats { unix_listener stats-writer { mode = 0666 } }

allows all processes to write stats.

To actually get some statistics, you need configure one or more metrics, see

https://doc.dovecot.org/configuration_manual/stats/

and you might also be interested in

Got it! Thanks so much, once again.

But imagine a very low-end VPS running just for few e-mail accounts, in order to keep the system resources free -at least a bit-, and if no stats needed for the admin/users, what configuration/block would you suggest? Otherwise, do I need to use both unix_listener stats-writer and unix_listener stats-reader?

Those are there by default, the config block just opens the default a bit. Stats will not really consume that much resources, in the end. Even on your low-end VM.
