Oh and answering the question in the thread's title. Akka message sends guarantee *at-most-once-delivery*, because the network is a dangerous place.
We provide *at-least-once-delivery* via this trait http://doc.akka.io/docs/akka/snapshot/scala/persistence.html#at-least-once-delivery but please be aware of the trade-offs this brings in.
