Step 3 Next, Click the Junk Store Installer icon to install the junk store on your Windows server.

Note SonicWALL recommends installing Junk Store on your server in order to fully utilize the newest functionality available with CASS 2.0.

Configuring Anti-Spam for UTM

When Anti-Spam for UTM is activated, set your preferences. Once these are configured, your email will be filtered and sorted according to your configuration.

The Email Threat Category Settings section enables administrator to set default settings for users’ messages. Choose default settings for messages that contain spam, phishing, and virus issues.

Use the dropdown options to choose how to handle messages in each threat category. The options are as follows:

Response	Effect
Filtering off	Anti-Spam for UTM will not scan and filter any email for this threat category, so all the email messages are delivered to the recipients.
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 can junk it if it is unwanted.
Store in Junk Box (default setting)	The email message is stored in the Junk Box. It can be unjunked by users and administrators with appropriate permissions. This option is the recommended setting.
Permanently Delete	The email message is permanently deleted. CAUTION: If you select this option, your organization risks losing wanted email.

If you are using more than one domain, choose the Multiple Domains option and contact SonicWALL or your SonicWALL reseller for more information.

User-defined Access Lists designate which clients are allowed to connect to deliver email. You can also set clients to be automatically rejected.

Advanced options allow you to set the following:

Setting	Description
Allow delivery of unprocessed mails when Comprehensive Anti-Spam Service is unavailable	If the Anti-Spam service is not enabled or unavailable for some other reason, you can choose to let all unprocessed emails go through. Spam messages will be delivered to users, as well as good email.
Tag and Deliver or Delete emails when SonicWALL Junk Store is unavailable	If the SonicWALL Junk Store cannot accept spam messages, you can choose to delete them or deliver them with cautionary subject lines such as “[Phishing]Please renew your account”
Probe Interval	Set the number of minutes between messages to the monitoring service.
Success Count Threshold	Set the number of successes required to report a success to the monitoring service.
Failure Count Threshold	Set the number of failures required to report a failure to the monitoring service.
Server Public IP Address	The IP address of the server that is available for external connections.
Server Private IP Address	The IP address of the server for internal traffic.
Inbound Email Port	The port your UTM has open to receive email from outside sources.
Use Destination Mail Server Private Address as Junk Store Address	If the Junk Store is on the destination mail server, select the checkbox. If not, enter the Junk Store IP address of where the server is located.
Enable Subsystem Detection	Detect other systems running in your mail stream.

Installing the Junk Store

Anti-Spam for UTM can create a Junk Store on your Microsoft Exchange Server. The Junk Store quarantines messages for end-user analysis and provides statistics. Log in to your Exchange system, then open a browser and log in to the SonicWALL Web management interface, and install the Junk Store.

Note that while SonicWALL supports non-Exchange SMTP servers, such as Sendmail and Lotus Domino, it is not required to install the Junk Store on one of these servers. Similar to the SonicWALL Email Security product, the CASS 2.0 feature allows you to install the Junk Store on a stand-alone server.

If you are using an Exchange server:

Step 1 Log in to your Exchange system, and on that system, open a web browser and log in to the SonicWALL Web Management Interface.

Step 2 On the Anti-Spam > Settings page, click the Junk Store Installer icon to install the Junk Store on your Windows Server.

Step 3 Your browser may warn you that the Web site is trying to load the SonicWALL Email Security 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. A progress bar is displayed on the page.

Step 6 The installer launches when it is fully downloaded. Note that migrating data in the Junk Store may take a long time 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.
