MailChannels Announces Traffic Control 4.0 Email Security

Web Hosting NewsSan Francisco, CA – MailChannels, a leading provider of email traffic shaping software, today announced that it has substantially increased the capacity and performance of its email security add-on with the launch of Traffic Control™ 4.0. One of the key benefits of using Traffic Control is that it efficiently pre-filters spam before it hits an organization’s mail server, reducing server costs by up to 95%. Leading service providers rely on the technology to streamline their email architecture and save money.

Version 4.0 of Traffic Control implements MailChannels’ innovative and effective traffic shaping technology on top of Nginx (pronounced “engine-x”), a lightweight, high-performance web server platform which is touted for its reliability and low resource consumption. Nginx is currently one of the fastest growing web servers on the planet, according to data published by the web site tracking firm NetCraft.

[swfobj src=”” width=”300/250″ class=”border: 1px solid grey;” align=”right”] Nginx was chosen because of its compact and high performance design. Traffic Control 4.0 is built on the same high performance foundation as Nginx, enabling large organizations and service providers to protect millions of users from spam using as little as one server. This is welcome news for service providers under the current recessionary economic conditions because it enables an immediate cost savings by eliminating costly email security servers.

“The rationale is simple: less spam traffic means less hardware required for our customers – saving them millions of dollars annually. In the past, increasing spam volume meant adding costly new hardware,” said Ken Simpson, CEO at MailChannels. “Nginx was a logical foundation because of its lightning speed and very low memory footprint.”

MailChannels’ technology shapes email traffic at the SMTP (Application) level, decreasing the volume of inbound spam that service providers need to manage. It separates senders into three distinct categories: bad senders are blocked, good senders are expedited for delivery, and new, unknown senders are restricted in bandwidth down to a few bytes per second. This traffic shaping forces 99.6% of spammers to drop off, without negatively affecting legitimate senders.

“By shaping email traffic at the SMTP level, abusive senders and legitimate senders are no longer competing for network resources, so our customers’ networks are not distracted by unwanted email,” said Ken.

MailChannels plans to contribute a number of improvements back to the Nginx open source community.

NEWS FACTS – Traffic Control 4.0:
• Processes 10 million messages per hour on a single CPU (10x faster than a standard MTA). An ISP with 3 million users could process all of their email traffic on just one server.
• Scales in all directions: from a single server all the way up to clusters of messaging servers.
• Integrates with existing carrier-grade spam filtering technology from Cloudmark, Commtouch, and others: By combining Traffic Control 4.0’s effective traffic shaping with accurate content filtering, service providers benefit from substantial cost savings.

About Nginx
Nginx is an open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. Written by Igor Sysoev in 2005, Nginx now hosts 3% of the world’s web sites and has a fast growing user base. Nginx is known for its speed, stability, rich feature set, simple configuration, and low resource consumption. Unlike traditional servers, Nginx doesn’t rely on threads to handle requests. Instead it uses a much more scalable event-driven (asynchronous) architecture. This architecture uses small, but most importantly, predictable amounts of memory under load. Nginx powers several high-visibility sites, such as WordPress, Hulu, and TorrentReactor.
