@ -172,6 +172,11 @@ By default, a persistent actor is automatically recovered on start and on restar
New messages sent to a persistent actor during recovery do not interfere with replayed messages. New messages will
only be received by a persistent actor after recovery completes.
.. note::
Accessing the ``sender()`` for replayed messages will always result in a ``deadLetters`` reference,
as the original sender is presumed to be long gone. If you indeed have to notify an actor during
recovery in the future, store its ``ActorPath`` explicitly in your persisted events.
