Anti-Spam: Stop Spam with Cross Analysis
No single analytic technique is enough to stop the constantly morphing forms
of spam. Even multiple techniques are not enough to keep spam at bay for
long. And rigid scoring often ends up blocking email that you actually want to
receive. MailFrontier takes spam management beyond arbitrary scoring with MailFrontier
Cognite™,
a revolutionary evidence evaluation system that identifies the sender,
analyzes the content, and applies a collaborative review to every email. These
methods are 98 percent effective at stopping spam. Only when all three elements
are simultaneously cross-analyzed can you have true confidence in your solution’s
handling of your company’s email.
Sender, content, and collaborative review are each excellent spam identifiers.
But if only a single method is used, the risk of false positives increases. However,
MailFrontier’s unique cross-analysis requires that at least two of our
independent techniques label a message as spam before it is marked as definite
spam, ensuring no good email is caught.
MailFrontier Cross Analysis: Examine the Sender, Analyze the
Content, Apply Collaborative Review
- Sender Authentication and Reputation
The
techniques in this category identify emails that falsify
their origin and check the reputation of the email sender.
Using both Sender ID Framework and MailFrontier Reputation™,
the MailFrontier solution not only validates the sender’s
claimed identity but also evaluates that sender’s reputation.
Sender ID provides an important part of the anti-spam solution
by identifying emails that have inconsistencies between the
claimed origin and actual origin. MailFrontier leads its
industry by incorporating this newly-adopted security standard
into its product. To

Spam can come from domains or addresses that are valid for
the claimed domains, which means that Sender ID analysis is
not enough. With the added technique of MailFrontier Reputation™,
MailFrontier’s anti-spam analysis not only validates
the claimed origin of the email through Sender ID, but also
assesses whether the sender has a good or bad reputation for
sending spam emails by cross-checking against MailFrontier’s
proprietary database—the industry’s largest—with
over 20 million entries to date.
- Content Analysis
Naïve Bayesian rules
don’t meet the challenge of today’s pervasive
spammer. Spammers use many techniques to confuse naïve
Bayesian filters into letting the spam messages through. MailFrontier’s
Adversarial Bayesian™ is designed for this environment. MailFrontier’s
Adversarial Bayesian uses a variety of techniques, including
Lexigraphical Distancing, which finds variations of spam
words, and Jibberish Detection, which detects strings of
nonsense text often found in spam. MailFrontier’s Adversarial
Bayesian offers the industry’s most comprehensive content
review.
- Collaborative Network
MailFrontier Self Monitoring
Active Response Team (SMART) Network™ is a real-time
network of over one million global users whose responses
enable MailFrontier to determine how to quickly identify
and react to new spam trends. In addition, since this network
gets “real” email,
MailFrontier SMART Network also understands legitimate email,
dramatically reducing the false positive rate. MailFrontier
immediately applies the results of its analysis through MailFrontier
SMART Network, passing the knowledge and value of its collaborative
network to its customers in real time.
Solving the Likely Spam Challenge: Personalized Spam Management
Unique to MailFrontier’s approach is Personalized
Spam Management. Instead of simply instituting a “one
size fits all” scheme for blocking email, MailFrontier
enables filtering at the organization, group, and personal
mailbox level, ensuring that only the email users want
to receive will reach their mailboxes.
Personalized Spam Management allows groups and individuals
within the organization to personalize their email management
settings within the parameters of the organization’s
global settings. This lets users receive only the email they
want while IT retains control. Without involving IT,
users and groups can contribute to solving the spam problem
with a full array of spam management features:
- Personal quarantine settings
Users can determine
the timing and frequency of the Junk Box Summary.
- Personal language settings
Users can choose from
a number of languages for their summary.
- Personal white and blacklists
Individual
white lists are automatically created and users can also
add senders they wish to allow or block without interfering
with corporate settings.
- Actionable Junk Box Summary
Users can take items
out of quarantine with one click.
The Result: No Spam and Headache-Free Email
Our unique, independent cross-analysis combined with Personalized
Spam Management, succeeds because it provides an absolute judgment
of definite and likely spam, and handles individual user preferences.
The result is a judgment that lets you confidently delete unwanted email, securely
quarantine suspect email, and accurately receive “good” email .
