I want to let you know about an MPP feature called Message Tracking that is quite useful for service providers or anyone that needs to have a compact record of each email message that they process. This feature was introduced in MPP quite some time ago but we never had a GUI interface for it until recently.

The idea with Message Tracking is that MPP will record a small record of each transaction in an SQL database. You can configure the level of detail that is stored, but the full detail is only a few bytes per message. MPP stores all types of information such as message id, remote relay IP, scan state, score of each scanner, message result, parse result and more. The database is very easy to query and very scalable.
