Hello, Currently working on using the old-stats plugin in dovecot version 2.3.10.1. What file permissions are recommended for the old-stats-mail and old-stats-user sockets? I was seeing a lack of data from the doveadm oldstats dump command until I adjusted the default config to the following: service old-stats { fifo_listener old-stats-mail { group mode = 0666 user = root } fifo_listener old-stats-user { group mode = 0666 user } } Not totally clear on which processes need read or write on those so any advice is appreciated.
