Hi, I'm aware its an async process, but despite sending test messages and then waiting a few minutes, the stats are still unchanged :

$ sudo doveadm replicator status                                                                                                                                                                                             Queued 'sync' requests        0                                                                                                                                                                                                      Queued 'high' requests        0                                                                                                                                                                                                      Queued 'low' requests         0                                                                                                                                                                                                      Queued 'failed' requests      0                                                                                                                                                                                                      Queued 'full resync' requests 0                                                                                                                                                                                                      Waiting 'failed' requests     0                                                                                                                                                                                                      Total number of known users   18

However if I manually run it using : sudo doveadm -D sync -u test@example.com -1 -d -N -l 30 -U

It syncs fine and the mails are visible on the standby server.

The master server is setup as per the docs : replication_dsync_parameters = -1 -d -N -l 30 -U plugin { mail_replica = tcps:foobar.example.com:11867 } service replicator { process_min_avail = 1 } service aggregator { fifo_listener replication-notify-fifo { user = foobar } unix_listener replication-notify { user = foobar } } service replicator { unix_listener replicator-doveadm { mode = 0600 user = foobar } } replication_max_conns = 10
