As mentioned in the comment by @wingedsubmariner, you can subscribe to the DeadLetter event on the main system EventStream to be notified when deadletters happen and be able to react to that situation in a more custom manner. In order to subscribe, the code would look like this:

context.system.eventStream.subscribe(myListenerActorRef, classOf[DeadLetter])

Then, the receive for that listener actor could look something like this:

def receive = {
  case DeadLetter(msg, from, to) =>
    //Do my custom stuff here
}

The structure of the DeadLetter class is:

case class DeadLetter(message: Any, sender: ActorRef, recipient: ActorRef)
