Perhaps I found a simple solution. I don't know if it's a good practice, 
please feel free to tell me what you think.

The server send a dummy message to test the client. If the client 
acknowledges, the server sends the actual message.

In this way if the client is down only the dummy message is in the 
queue, the clients acks when reconnects but the server will ignore it.

If the connection is lost just after the ack (very unlikely) the client 
will receive the naked message, without the dummy one. So it will reject it.

In other words, I'm going to test the connection a while before send the 
message.

What do you think about?
