Dovecot Replication of Maildirs: Couldn't create lock file ... no such file or directory

[Asai]

Greetings,

I'm setting up replication and am getting this error from the server 
where the replicated mails are being initially created:

Aug 27 11:03:53 molecular dovecot: dsync-server(user at domain.org): Error: 
Couldn't create lock /vmail/domain.org/user/home/.dovecot-sync.lock: No 
such file or directory

Can anyone shed some light on this?

Here's the Replicator config of the server which is being replicated to 
(initially), and it is identical basically with the "master" server:

mail_plugins = notify replication

service doveadm {

         inet_listener {

                 port = 1234

         }

}

service replicator {

         process_min_avail = 1

         unix_listener replicator-doveadm {

                 mode = 0600

         }

}

service aggregator {

     fifo_listener replication-notify-fifo {

         user = vmail

         mode = 0600

     }

     unix_listener replication-notify {

         user = vmail

         mode = 0600

     }

}

plugin {

         mail_replica = tcp:sub.domain.org:1234

}


And doveconf -n:

Not sure if this helps but here's the ls -la output of /var/run/dovecot:
