# Statistical Filtering

This page allows you to create and maintain a host specific exclude list, specify what action to take when a message is identified as spam, and specify whether to use the primary host’s word counts or create new ones. The advanced options control the underlying functionality of the statistical filtering component. The list box displays the contents of the current exclude list.

1. Select which host's statistical filtering settings will be used for the current host. Select from:

- None. Disables statistical filtering for the host. If this option is cleared, all options on this screen are disabled.

- Use Current Host. Creates new statistical filtering settings for the current host.

- Use Primary Host. Select this option if you want to use the primary host's antispam-table.txt file instead of creating a new one for the host. Enabling this option also saves memory by reading the file directly from the primary host’s directory. Note that this option is disabled for the primary host.

2. Select which of the following tasks you want to perform:

## Adding a word to the Exclude List

## Editing a word in the Exclude List

## Deleting a word from the Exclude List

3. Specify one of the following actions to take on a message that is identified as spam:

- Delete. Immediately deletes the message.

- Forward to Address. Forwards the message to the e-mail address that is entered in the Target text box. If no address is entered, spam is sent to a "bulk" mailbox for the "root" account.

- Insert X-Header (default). Inserts an X-Header into the message indicating that it was identified as spam by statistical filtering.

- Forward To Mailbox. Forwards the message to the mailbox entered in the Target text box.

- None. No action is taken on the message.

4. If you want to modify the subject of spam messages, select Prefix Subject With and enter text into the textbox.
5. Click Save.
