[Dovecot] Debian Wheezy Dovecot Replication no updates on message deposit

[Milan Cvetkovic]

Hi,

I am trying to setup dovecot replication based on:

http://wiki2.dovecot.org/Replication
http://www.dovecot.org/list/dovecot/2013-January/087674.html

I know that 2.1.7 is dated, but I would refrain from upgrading, if not 
necessary.

The problem I have is pretty much same as the one described in 
http://www.dovecot.org/list/dovecot/2013-January/087674.html:

I have vmail user on both systems, setup with ssh public key logins with 
empty passphrase. Apparently, dsync happens only on periodic updates. If 
a message is deposited on one server, it will only propagate to the 
other once a while.

Thanks, Milan.

Here is doveconf -n output:
