    ActorRef pingPongActor = actorSystem.actorOf(PingPongActor.props(lock).withMailbox(config.getMailBoxName()), "pingpongactor");
    actorSystem.mailboxes().settings();
    lock.lock();
    try {
        // 12th message is sent to dead letter.
        for (int i = 0; i < 12; i++) {
            pingPongActor.tell("ping", mockReceiver.testActor());
        }
        mockReceiver.expectMsgClass(twentySeconds, DeadLetter.class);
    } finally {
