I got confused after a big migration that dovecotstats was acting up. Turns out, as mentioned on https://doc.dovecot.org/configuration_manual/stats/ , that dovecot stats using doveadm were completely redone in dovecot 2.3 (first release in December 2017, last 2.2 security release in august 2019). The command executed in dovecotstats is therefore no longer valid. I wonder whether the plugin should be marked to only be useable with 2.1 and 2.2, or whether it should be removed altogether.
