Example: Create a blog
1. Create the structure
- Create the InBox `globalinbox`
- Create the Folder `webblog`
- Mark `webblog` with `IBlogMailDropBoxMarker` (using @@manage_interfaces)

- Reindex `webblog`
2. Create the content rule
- Event trigger: Object added to this container
- Condition: Email Header

- Action: Deliver
Specify `webblog` as key.

- Action: Delete Object
3. Assign the created rule to the `globalinbox`

4. That's all
This would be sufficient to create the News items. Of course, you're free
to specify content rules for the `webblog` too. For example
to publish news items after they have been added, so anonymous visitors would see them,
or anything you can imagine.
