Hello,
- Dovecot 2.3.18 (originally Dovecot 2.3.16, but upgraded in an attempt to fix issue)
- Ubuntu 20.04 using Dovecot repo
In my organization have run a cluster of dovecot proxy machines, with
the director service enabled in a transition period as we have
migrated all our users to do direct proxying to backend (e.g.
proxy=y, host=192.168.0.2), bypassing the director service.
Now that all users have been migrated, it is time to disable the director service. However, even after removing all director configuration ("doveconf -n | grep director" returns nothing) and restarting the entire dovecot service (not just "doveadm reload"), the error log still spits out these errors:
2022-04-29T11:27:25+0200 director: Error: Empty server list 2022-04-29T11:27:25+0200 director: Fatal: Invalid value for director_mail_servers setting 2022-04-29T11:27:25+0200 master: Error: service(director): command startup failed, throttling for 60.000 secs
Why is this happening? It's not critical, and logins work fine without the director service running, but I'm trying to figure out why and stop the log noise.
doveconf stuff:
