dovecot - Oct 2013 - Dovecot replication - I'm stuck

Hi,

I've been following the wiki document at
http://wiki2.dovecot.org/Replication, but I've become stuck.

I'm running version 2.1.3 on NetBSD 5.2 (v2.2+ isn't available as a
package
yet, and compiling my own is well outside my wheelhouse).

I have a couple of questions:

The wiki page keeps referring to "vmail".  Is this a just system user
I
need to create?  Presumably on both Dovecot boxes?

If I don't use virtual users, do I need this?

Here is my dovecot -n:


# 2.1.3: /usr/pkg/etc/dovecot/dovecot.conf
# OS: NetBSD 5.2 cobalt
auth_mechanisms = plain login
dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u
listen = 192.168.1.1
login_greeting = Go on then, let's have it...
mail_location = mbox:~/mail:INBOX=/var/mail/%u
mail_plugins = " notify replication"
passdb {
  driver = passwd
}
plugin {
  mail_replica = remote:vmail at server2.mydomain.com
  replication_full_sync_interval = 1 hours
}
protocols = imap
service aggregator {
  fifo_listener replication-notify-fifo {
    user = vmail
  }
  unix_listener replication-notify {
    user = vmail
  }
}
service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0660
    user = postfix
  }
  user = root
}
service imap-login {
  inet_listener imap {
    port = 0
  }
}
service replicator {
  process_min_avail = 1
  unix_listener replicator-doveadm {
    mode = 0600
  }
}
ssl_cert = </etc/openssl/certs/mail.mydomain.com.crt
ssl_key = </etc/openssl/private/mail.mydomain.com.key
userdb {
  driver = passwd
}
protocol lda {
  postmaster_address = postmaster at mydomain.com
}


Any help would be greatly appreciated, as I'd really love to get this
working.

Thanks,

Yes, create the vmail user on both boxes and set up key-based 
authentication via SSH so the two can talk to each other without passwords.

Also, best upgrade to dovecot 2.2 as mentioned on the wiki page, as only 
2.2 supports incremental syncing of mailboxes.

Regards,
Lucas

You know, we go to the gym to keep the body fit. Similarly the mind needs some
rest. The mind is bombarded with so many impressions. Our mind has been
bombarded by impressions the whole time. It needs a different kind of rest other
than sleep. And meditation is such a rest. It calms the mind. energizes the
spirit and makes the body more strong and vibrant. improves the immune system.
The immune cells, the T-cell count go higher through Sudarshan Kriya and
meditation. And you feel so nice inside. - Sri Sri Ravi Shankar

No. If you're using system users, each user owns his/her own mail.
Replication would have to be done as root (or of course by a special 
user with sudo or other privilege escalation.)

Scroll further down that page to the part about "dsync wrapper script 
for root SSH login (v2.2+)", but oops, you don't have 2.2. Sad. I 
guess you'll either have to upgrade or figure out another way to do 
this (probably out of Dovecot scope.)
