After testing this again, I noticed that it is there: $ apt-cache show dovecot-core Package: dovecot-core Architecture: amd64 Version: 1:2.3.7.2-1ubuntu3.3 Priority: optional Section: mail Source: dovecot Origin: Ubuntu
$ dpkg -L dovecot-core | grep stats /usr/lib/dovecot/modules/lib90_old_stats_plugin.so /usr/lib/dovecot/modules/old-stats /usr/lib/dovecot/modules/old-stats/libold_stats_mail.so /usr/lib/dovecot/modules/old-stats/libstats_auth.so /usr/lib/dovecot/old-stats /usr/lib/dovecot/stats /usr/share/man/man1/doveadm-stats.1.gz $ doveadm stats dump Fatal: net_connect_unix(/var/run/dovecot/stats-reader) failed: No such file or directory Maybe you have mismatch between running dovecot and doveadm somehow?
