Can you post to the list your working configurations for dovecot?
(This is based on http://dovecot.org/list/dovecot/2012-March/064513.html)
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:vmail@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:vmail@mx1.FQDN
# run full synchronization mode every other hour
#
replication_full_sync_interval = 1 hours
}HTH, Michael
