This is part of the plone's core and can be configured by a site admin later through the web. In a current sandbox go to "Site Setup" -> "Content Rules". 
The configured rules can be activated globaly or just for some folders in the site.

If we should setup something, we need more informations.

To give you some more informations here are some of the functionalities:

It catches Events:
- Object created
- Object modified
- Object removed
- Workflowstate changed

There can be conditions, e.g.:
- Which Content Type
- Which Workflowstate
- Which users group or role

Do some action, e.g.
- Mail a message to an email address
- show a message to the user 
- copy, move or change the workflowstate

Hm. I am closing this bugreport due to the lack of information. Quim, please reopen if you have anything to add.
