Sophisticated Spam Detection
Spam is fast becoming the number-one IT pain point for enterprises
worldwide. Today, between 45% and 50% of email is spam, and Radicati Group
expects this to reach 70% by 2007.
This deluge of unwanted mail results in drained IT personnel
resources, decreased network bandwidth and email storage space, reduced employee
productivity, increased legal risk and costly network downtime. In all, Ferris
Research estimates that spam could cost businesses $10 billion.
Developed for high-volume messaging environments, MX Logic's Email
Defense Service provides the most comprehensive and effective spam-blocking
product on the market today.

Multi-Layered Spam Filtering
Unlike most spam filtering solutions, which use one or two
spam-classification techniques, MX Logic's Stacked Classification Framework(SM)
aggregates the most effective spam filters and techniques in the industry,
currently leveraging the strengths of five spam-fighting filters including the following:
- Bayesian Statistical Analysis
- Heuristics Rules-Based Analysis
- Distributed Checksum Matching
- Distributed Deny Lists and Global Deny Lists
- Customer-Defined Deny and Allow Lists
Each of the five filters dynamically calculates the spam
probability of every message. Through an aggregation and analysis of these
spam-likelihood scores, our patent-pending, multi-layered spam detection system
provides extremely effective blocking of spam.

More on Virus Protection
In a world increasingly dependent on Internet communication,
viruses represent one of the most significant information security threats to
the enterprise.
MX Logic’s Email Defense Service provides highly effective,
organization-wide virus and worm protection, enabling business continuity and
cost containment. It identifies, quarantines, blocks and strips viruses and
worms at your network perimeter—before they enter or leave your messaging
infrastructure.
As new viruses are deployed and released, protection depends on
downloading new virus signatures that identify infected traffic. That’s why MX
Logic’s Threat Management Team, comprising some of the world’s leading messaging
experts, leverages McAfee and Sophos and proactively updates their virus
signatures every 5 minutes—minimizing outbreak and infection risks and securing
your enterprise-messaging infrastructure.

Confidentiality and Security Overview
The concept of 3rd party filtering can cause concern for security and
confidentiality. This need not be a concern for the following three reasons:
Reason 1
To make this filtering service function, we have to create a MX
Record on our Email Server. This MX Record creates a masking affect on the path
of your email.
Reason 2
All emails handled by this 3rd party go through a proxy server in
a matter of seconds without creating a permanent footprint of the email. There
is literally no time to read any of your messages that are passed to you.
Reason 3
Any messages quarantined AKA captured as spam, are temporarily
stored in an encrypted fashion by placing pieces of the message in different
databases, then upon retrieval via an SSL protected web page you can permanently
retrieve or delete as you see fit. Since “false positives” (messages that are
flagged as spam, but were legitimate), are captured at a rate lower than 1%,
this 3rd reason rarely comes into play.
