Akka Actors - Change default behavior of messages arriving in actors

Is it possible in Akka Actors to install some kind of 'hook' that allows you to run a self-defined piece of code every time a new message arrives in an actor? Note, this is not the moment when the actor starts handling the message with receive but the moment when the message arrives in the actor and is put into its mailbox. Also note that I want to change the default behavior, not just the behavior for one individual actor. Ideally I would change this behavior at just one spot throughout my code and it would affect all actors automatically, or by only requiring 1-2 lines of code in each file/actor (such as an import statement).

For example, using this hook it should be possible to log a message every time it arrives or to calculate and print the fibonacci of the size of the mailbox before/after insertion.

If you control the spawning of the actor (or are willing to use this mailbox as the default for actors which don't specifically set a mailbox), you can use a custom mailbox. See the docs for details.
