dovecot - Nov 2014 - how to start a replication master-master correctly

Hi all, I currently have one dovecot 2.2.15 working and I would like to add
a second master server. If I configure the second server and enable the
dsync in both servers, the sync will copy everything from A to B ? I mean,
B server won't remove messages in A as it doesn't have anything in its
users mailbox?

The second master server will be a cold server just for contingency.

Thanks

That is :-)

But for dsync to work correctly in 2.2.15, You have to enable empty 
password for connection from your servers, this is strange ... and this 
wasn't need in previous version (at least 2.2.12)

For example, (and correct me if I'm wrong or if I can disable empty 
password), add a passdb source :

passdb {
         driver = static
         args = nopassword=y 
allow_nets=127.0.0.1/32,local,IP_OF_SERVER_A,IP_OF_SERVER_B
}

Well, it's ok in 2.2.9 for dsync password.
Eduardo, if you have debian-based system I suggest you install dovecot
from apt
