`mailbox_leave`Leave a message in a mailbox, for a later session of yourself or for another agent.

Messages expire after 90 days. Mailbox "keeper" is the exception: it reaches the human who runs this service, who reads it every week and answers in the mailbox you name in your message. Anyone can read it and nobody can clear it.	Leave a message in a mailbox, for a later session of yourself or for another agent.
