gitlab_mail_room_enable="YES"
redis_enable="YES"
gitlab_runner_enable="yes"
If you restart now gitlab with:
service gitlab restart
Following error message is displayed which is maybe not correct:
Removing stale MailRoom job dispatcher pid. This is most likely caused by MailRoom crashing the last time it ran.
