Installing the Junk Store

The Comprehensive Anti-Spam Service can create a Junk Store on your Microsoft Exchange server. The Junk Store quarantines messages for end-user analysis and provides statistics, but is not required by the Anti-Spam service.

Note	The Junk Store feature is not supported on the SonicWALL TZ 100 series appliances.

If you are using an Exchange server, perform the following steps to install the Junk Store:

Step 1

Log in to your Exchange system, and on that system, open a Web browser and log in to the SonicOS Web management interface.

Step 2

On the Anti-Spam > Settings page, click the Junk Store Installer icon to install the Junk Store on your Exchange server.

Step 3

Your browser may warn you that the Web site is trying to load a SonicWALL add-on. Click in the Information Bar and select Install ActiveX Control in the popup menu.

Step 4

On the Security Warning screen, click Install to install the ActiveX Control.

Step 5

On the Anti-Spam > Settings page, click the Junk Store Installer icon again to begin downloading the installer.
A progress bar is displayed on the page, changing color as it nears completion.

Step 6

The installer launches when it is fully downloaded.
Migrating data in the Junk Store may take a long time. Wait for the data migration to complete.

Step 7

Navigate to the Anti-Spam > Status page and verify that the SonicWALL Junk Store is Operational . It typically takes about 15 minutes for the Junk Store to become operational.

Configuring the Email Threat Categories

The Email Threat Categories section enables the administrator to configure the settings for users’ messages. Choose settings for messages that contain spam, phishing, and virus issues. The default settings are:

•	Likely Spam – Store in Junk Box

•	Definite Spam – Permanently Delete

•	Likely Phishing – Tag with [LIKELY PHISHING]

•	Definite Phishing – Store in Junk Box

•	Likely Virus – Store in Junk Box

•	Definite Virus – Permanently Delete

Use the drop-down options to choose how to to handle messages in each threat category. Your options are:


Response	Effect
Filtering off	SonicWALL Anti-Spam service will not scan and filter any email, so all email messages in this category are delivered to the recipients without modification.
Tag With	The email is tagged with a term in the subject line, for example, [JUNK] or [Possible Junk?]. Selecting this option allows the user to have control of the email and junk it if it is unwanted.
Store in Junk Box	The email message is stored in the Junk Box. It can be unjunked by users and administrators with appropriate permissions.
Reject Mail	The email message is returned to sender with a message indicating that it was not deliverable.
Permanently Delete	The email message is permanently deleted. CAUTION : If you select this option, your organization risks losing wanted email.
