Please tell me about Dsync replicator.

The following are set to enable the "replication" plug-in

/etc/dovecot/conf.d/10-mail.conf

*---mail_plugins = notify replication---*

And I made the following file

/etc/dovecot/conf.d/30-dsync.conf

*---service replicator { process_min_avail = 1} dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%uplugin { mail_replica = remote:root@"ServerIP"} service aggregator { fifo_listener replication-notify-fifo { user = mail } unix_listener replication-notify { user = mail }} service replicator { unix_listener replicator-doveadm { mode = 0600 }} replication_max_conns = 10 plugin { # When saving a new mail via IMAP or delivering a mail via LDA/LMTP, # wait for the mail to be synced to the remote site. If it doesn't finish # in 2 seconds, return success anyway. # replication_sync_timeout = 2s}---*

But replication gives an error

*Error: open(/var/run/dovecot/replication-notify-fifo) failed: Permission denied*

Why is this?

By the way, When 30-dsync.conf is changed as follows, it works only for one user

*---service aggregator { fifo_listener replication-notify-fifo { user = "one user name" } unix_listener replication-notify { user = "one user name" }}---*

However, I want to work with all mail users. Please help me what to do.

My configuration is as follows
