We introduced the Audit Database in R10.6 as part of our Messaging Solution (Internet and X.400). Its initial functions are to support message tracking and anti-spam quarantine. There is lots more coming. The next set of features will be decent statistics, and we'll be providing lots of options, including graphing. We'll send out some screenshots in a while.
The Audit Database is becoming a core part of our product set. We chose to implement with standard components, and in particular Tomcat, Postgres, and JDBC. A benefit of using these packages, is that customers will be able to share them with other applications. We decided that shipping these componets as a part of our release would be a nuisance to customers who already have them for other purposes (as well as making our distribution a lot bigger). Therefore, we've kept them separate.
A consequence of this is that installation of this component needs additional external packages, which needs some basic configuration. We've documented this, but many customers and evaluators have chosen not to look at this component, which is a pity.
We think that including the packages with the Isode products woud be a mistake. We're going to add some "quick start" documentation, to help get going with the Audit Database, and also make pointers to this clear from the basic installation information.
