Thank you for your explanation! I tried to solve the problem by implementing my own mailbox, that deletes old messages when full (that is my requierement).
As I understand you, this will not work, as the stashing is not using the mailbox? But how can I change the stash-capacity behaviour, so that I remove the oldest messages, instead of throwing the StashOverflowException? If the stashing is not using the mailbox, it is mayby not possible to plug in my owm implementation?
