Re: [Dovecot] v2.2.beta2 released

Thank you very much Michael.

I'll set it up again, because I think that initially I was not using any aggregator service. My setup is a little atypical as I have servers spread-out on 2 (soon 3) continents that are connected via slow uplinks.

Hopefully the v2.2 is more stable and less buggy for the synch ;)

Best regards, Andrei

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
