The higher level goal is to facilitate generation of RFC 3464 messages in response to delivery failures. The first step is to introduce this synchronous (wrt. message processing flow) event hook that will allow the message content to be optionally captured by the hook implementation. These need to be synchronous in this way, otherwise a terminal dispoisition (eg: permanent failure) may decide to remove the message from the spool concurrent with the log processing. That concurrency concern doesn't exist for the existing logger implementations because they make a point of capturing all information from the message prior to enqueuing the data to the logger. Later commits will provide some convenience functions for bounce message generation based upon that state.
