New Software Add-On Improves SpamAssassin Effectiveness by 85 Percent

Traffic Control for SpamAssassin is an effective add-on that Apache SpamAssassin administrators large and small should evaluate

MailChannels Corporation, the global leader in email traffic shaping software, today announced that Apache SpamAssassin users can now download Traffic Control to dramatically enhance the performance of SpamAssassin. Traffic Control uses email traffic shaping to reduce spam by 85 percent more than blacklisting while delivering a 50 to 100-fold improvement in peak load handling. With this release, SpamAssassin users can join leading universities, service providers, and Fortune 500 companies, who have benefited from Traffic Control's ability to provide a more reliable and cost effective email service.

Traffic Control 3 for SpamAssassin is available at http://mailchannels.com/download. Commercial use requires a license. A 30-day evaluation is provided free of charge.

"Traffic Control for SpamAssassin is an effective add-on that Apache SpamAssassin administrators large and small should evaluate," said Justin Mason, author of SpamAssassin. "It is clear that there is no perfect defense to spam, and while SpamAssassin provides a level of protection, it can be resource-intensive. Traffic Control for SpamAssassin provides comprehensive coverage of a wide spectrum of spam and other threats, while delivering major scalability benefits."

Despite the improving accuracy of SpamAssassin, email administrators still struggle to keep up with the continuous onslaught of new spam outbreaks. Spammers respond to better filter accuracy by increasing the volume of spam that they send. Since spam volume is unpredictable, periodic outbreaks overwhelm email systems causing delivery delays and allowing unacceptable amounts of spam to pass into end user inboxes. SpamAssassin is a great spam filter, but like other spam filters it needs to be paired with an effective protocol-layer defense.

Ongoing analysis of customer data by MailChannels shows that 85 percent of spammers abort email delivery when they are connected to a server that severely restricts their bandwidth. Traffic Control exploits this characteristic spammer behavior and others to deflect a significant portion of spam "in flight" before it hits the spam filter or mail server. High spam traffic impacts overall email by creating email delivery delays. After deploying Traffic Control, SpamAssassin users that are experiencing slow times to process messages will see a dramatic drop in email connection traffic.
