Anti-Spam Techniques

This chapter describes how you can use SonicWALL Email Security to block senders, or ensure that
senders you approve can send you email.

Managing Allowed and Blocked Lists

Managing your Allowed and Blocked lists can help prevent email you want from ending up in your
Junk Box and keep email from legitimate-looking but annoying senders from cluttering up your
inbox. Use the Anti-Spam Techniques window to create your own lists of senders from whom you
want to allow and block email.

SonicWALL Email Security provides separate lists for people, companies (domains), and mailing
lists. For each type of list, click the Allowed and Blocked tabs to see the different allowed and
blocked lists. Search for allowed and blocked names, company, and lists in the Anti-Spam
Techniques window. Click Search and type the name of the person, company, or list.

SonicWALL Email Security 7.2 User Guide | 9

CHAPTER 3

Note:

z

An email address or domain cannot be on both the Allowed and Blocked lists. If you add an
address in one list that already exists on the other, SonicWALL Email Securi ty removes the
address from the other list.

organization Allowed list; users cannot delete these companies.

3. Click Allowed to view the companies and domains in the Allowed list.

Adding a Company or Domain to the Allowed List

A domain is the part of an email address that represents the company or organi zation sending th e
email. For example, in the address [e-mail], “sonicwall.com” is the domain name.
Companies may have several domains.

X To enter the name of the domain into your allowed list

2. Click Delete to delete that domain from the Allowed list.

12 | Chapter 3 - Anti-Spam Techniques

Adding Lists to the Allowed List

Email messages from mailing-list servers do not always come from the same email address or
FROM: field in the address. This makes it difficult to add list messages to the Allowed list.

The email messages are from the person who posted the message to the list-server and the
message is addressed to the mailing list. You can only add and delete Allowed lists.

X To add email lists to Allowed Lists

1. Navigate to Anti-Spam, Anti-Phishing > Lists.

2. Click Add to add mailing lists to Allowed Lists.

3. Enter the address for one or more of the lists, pressing Enter after each one.

4. Click Add. The updated Allowed Lists window appears.

Configuring Anti-Spam Aggressiveness

If you want to change how aggressively your mail is filtered, use the Anti-Spam Aggressiveness
window. Increasing the aggr essi vene ss means you get le ss spam, but increases your c hances of a
valid email being classified as spam. SonicWALL recommen d s us in g the default setting of Medium
or 3 unless you require different settings for specific types of spam blocking.

SonicWALL Email Security 7.2 User Guide | 13

Note: To use your companies default settings, use the Adhere to Corporate/Group Defaults

checkbox. If your IT department enforces these settings, the checkbox is dimmed; you cannot
change blocking levels.

Configuring SMART Network Aggressiveness Settings

You can adj ust the level of influence co mmunity input has on organizati on spam blocking, produced
by the Self-Monitoring Active Response Team (SMART) network. Updates are provided to your
gateway server at defined intervals.

To adjust your collaborative settings, click one of the radio buttons from Mild (1) to Strong (5).
A setting of 5 means that you are comfortable with the collective experie nce of the SonicWALL user
community. A setting of 1 or 2 indicates that you are skeptical of the collective experience and want
to judge more email for yourself.

Configuring Adversarial Bayesian Aggressiveness Settings

This aggressiveness setting determines how likely an email message is to be identified as junk
email. Selecting a stronger setting makes SonicWALL Gateway more likely to mark a message as
spam.

Determining Amounts and Flavors of Spam

You can determine how aggressively to block particular types of spam, including sexual content,
offensive language, get rich quick schemes, gambling, and advertisements.

For each of the spam flavors:

z

Choose Mild (1) to be able to view email that contains terms that relate to these topics.

z

Choose Medium (2 - 4) to cause SonicWALL Email Security to tag this email as likely junk.

z

Choose Strong (5) make it more likely that email with this content is sent to your junkbox.

14 | Chapter 3 - Anti-Spam Techniques

Screening Messages in Other Languages

Many spam messages are in a language other than the one you do business in. To filter out
messages based on language they were written in, use the Languages window. For each language,
you can choose allow, block, or have no opinion. For example, you might want to receive all
messages in German, but block messages in other languages. You might also have no opinion about
receiving messages in other languages.

CHAPTER 6

Junk Button for Microsoft Outlook

This chapter describes the SonicWALL Junk Button for Outlook, a small application that can be
added to Microsoft Outlook. The Junk Button allows end-users to report spam messages to the
SonicWALL GRID Network. The GRID Network’s ability to detect spam is enhanced each time a user
uses the Junk Button.

z

“Feature Overview” section on page 27

z

“How Does the Junk Button Work?” section on page 27

z

“Using the Junk Button” section on page 28

Feature Overview

When a user presses the Junk Button, the highlighted email message is moved to the user’s Outlook
Deleted Items folder and the message’s thumbprint is added to the GRID Network thumbprint
database. As more thumbprint reports accrue about a message, SonicWALL Email Security
appliances and installations are more likely to filter that message as spam so that other users do
not see it.

Benefits:

z

Empowers users—Users are not just getting rid of their own spam, they are helping themselves
and other users around the world.

z

Improves enterprise spam filtering—The enterprise benefits from the human intelligence of its
members because the amount of spam the organization as a whole receives is reduced.

z

Decreases helpdesk requests—Users can report and dispose of spam themselves.

How Does the Junk Button Work?

The SonicWALL Junk Button allows you to remove spam from your inbox by clicking a small toolbar
button in Microsoft Outlook. Your feedback helps block spam sent to you, your organization, and
other people using SonicWALL Anti-Spam and Email Security products.

The SonicWALL GRID Network collects your “Junk vote”, parsing the spam email into its attributes
and combining your vote with other sources. These reputation updates, called thumbprints, are
delivered back to your SonicWALL Email Security system every five minutes, improving your
system’s ability to block spam, phishing, and virus emails.

The text of messages is not reported to the GRID Network. Instead, the message is converted into
a uniquely identifying hash, and only this hash is used in the thumbprint.

28 | Chapter 6 - Junk Button for Microsoft Outlook

Using the Junk Button

The Junk Button is used to remove any junk e-mail messages that arrive in your inbox and place
them in your Deleted Items folder.

X To use the Junk Button:

1. A junk e-mail arrives in your inbox.

2. Highlight the e-mail message by selecting it.
