Dovecot 2.2.27 (c0f36b0)

I'm trying to configure dovecot to backup all my email to a secondary server using "dsync".

I got it working in "sync" mode or two-way synchonization, that means whatever happens in one server gets replicated in the other.

However, documentation also says that a one way synchronization is posible, yet, after spending a good amount of hours searching, I failed to find what do I have to modify in my "30-dsync.conf" to do so.

My 30-dsync.conf reads as follows:

#This sets globally the port needed to connect #to the doveadm service #doveadm_port = 12345

Set the password globally to use for connecting to

and requiring for the doveadm service

doveadm_password = +++++++++++++

Set the directory for validating certificates

provided when running with SSL enabled

Should be the standard OpenSSL certificate directory by default

ssl_client_ca_dir = /etc/ssl/certs

Configure the doveadm service to listen

service doveadm { inet_listener {

port to listen on

   port = 12345
       # enable SSL
     #  ssl = yes
}

}

Configure the aggregator service for notifications

service aggregator { fifo_listener replication-notify-fifo {

Your mail user that's managing files generally is used here

   user = +++++
   mode = 0755
}
unix_listener replication-notify {
  user = +++++
  mode = 0755
}

}

Configure the replicator service

service replicator { user = root process_min_avail = 1 unix_listener replicator-doveadm { user = root mode = 0755 } }

replication_dsync_parameters = -d -N -l 30 -U -x nobody

Configure target hosts for replication

tcps can be tcp if you don't want to connect with SSL

:port can be omitted if it's the default set globally for doveadm

plugin { mail_replica = tcp:*.*.*.*:12345 }

Thanks.
