Can you post to the list your working configurations for dovecot?
(This is based on

My design:
single user "vmail" to run dsync over ssh
(one may use root instead)
Thus, my prerequisites are:
create "vmail" user accounts at both servers (example: mx1 and
mx2)
exchange ssh-keys for ssh authentication between both servers
involved
My relevant parts from dovecot.conf, identical for both servers:
## --- DSYNC REPLICATION
----------------------------------------
# ssh command line used in dsync replication
# added:
# -p xxx (ssh port)
# -o mail_plugins= (omit mail_log plugins for
dsync)
#
dsync_remote_cmd = ssh -p 44488 -l%{login} %{host} doveadm
-omail_plugins= dsync-server -u%u -n%{namespace}
# aggregator, replicator, doveadm, and config needed, and
dsync_remote_cmd (see above)
#
service aggregator {
# give enough permissions for mail processes
#
fifo_listener replication-notify-fifo {
user = vmail
mode = 0600
}
unix_listener replication-notify {
user = vmail
mode = 0600
}
}
service replicator {
# start replication at startup
#
process_min_avail = 1
}
service doveadm {
# if you're using a single virtual user, set this to
start ssh as vmail (not root)
#
user = vmail
}
service config {
# needed to grant access to /var/run/dovecot/config for
service doveadm
#
unix_listener config {
user = vmail
}
}
The following part is for server mx1, only:
-------------------------------------------
# dsync replication plugin
#
plugin {
# this host replicates to remote host
#
mail_replica = remote:vm...@mx2.fqdn
# run full synchronization mode every other hour
#
replication_full_sync_interval = 1 hours
}
The following part is for server mx2, only:
-------------------------------------------
# dsync replication plugin
#
plugin {
# this host replicates to remote host
#
mail_replica = remote:vm...@mx1.fqdn
# run full synchronization mode every other hour
#
replication_full_sync_interval = 1 hours
}
HTH,
Michael
