doveadm log reopen not works with 2.2.33

Hi,

after the upgrade from dovecot 2.2.32 to 2.2.33 we notice that the /var/log/director/director.log was empty and the log are write in the logrotate file es. /var/log/director/director.log-20171201.

Log path is dovecot is:

log_path = /var/log/director/director.log

Logrotate configuration is:

/var/log/director/director.log { daily rotate 31 missingok notifempty compress delaycompress sharedscripts postrotate doveadm -i director log reopen endscript }

and worked fine until the last dovecot upgrade. Now the only way to "reopen" the log file is doveadm reload.

Is this a know bug?

Thanks
