The weird thing is, that my logs are completly empty. I see only the dovecot
startup messages and nothing else. I don't understand why the replication
never starts by itself or why there are no errors or anything else in the log. I
already read the dovecot replication howto in the official documentation, but
IMO I've setup everything already like in the docs.
