Public bug reported:
It looks like there is no way for a MM3 plugin to be signaled for a new posting.
It would be great if core could provide a notification to the plugins that have subscribed to this event when a new post occurs.
This notification should carry some interesting information, like the number of recipients and the message size.
This request is also essential for the MM3-Metrics module (https://launchpad.net/mm3-metrics).
