Anti-Spam > Settings
Once you have registered Anti-Spam for UTM, activate it to start your UTM appliance-level protection from spam, phishing, and virus messages.
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:
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:
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:
