Configuring custom filtering

Custom filtering provides sophisticated filtering for Domino server journal archiving. For example, you may want items with a particular subject, sender or recipients to be sent to a separate archive, or you may want messages sent within the company to be given a special retention category of "Internal".

You can set up default filters that apply to all archiving tasks that are enabled for custom filtering. In addition, you can create separate custom filters for specific Domino journaling locations.

If custom properties have been added to items, you may want these properties indexed for selected items.

Instructions are provided on how to extend custom filtering to use the custom properties feature.

See About configuring custom properties.

To implement custom filtering

Enable custom filtering by configuring registry settings.

See Configuring registry settings for Domino server journal filtering.
Create filter rules and actions. These are held in one or more XML ruleset files, which must be placed in the folder, Enterprise Vault\Custom Filter Rules.
Restart the archiving tasks that have custom filtering enabled.

The following message is sent to the Enterprise Vault event log when the Domino server archiving tasks start:

```
The following message is sent to the Enterprise Vault event log when the Domino server archiving tasks stop:
