Overview
Traffic Control is the world's fastest and most flexible SMTP proxy, delivering 15 million messages per hour on a single eight-core Intel® Xeon® server. Traffic Control offers a combination of innovative features to address needs of the largest email providers.

Ultra-scalable inbound traffic management
Developed by experts in botnet behavior, Traffic Control provides the world's most effective email traffic shaping solution. Traffic shaping attacks the financial incentives that drive spammer behavior, cutting off spam before other approaches like blacklisting and content filtering have had time to catch up.
Intelligent outbound spam filtering
The best way to control spam is to stop it at its source, which is why Traffic Control offers a comprehensive set of features aimed at controlling outbound spam. Whether it's filtering your entire subscriber network through a small cluster of Traffic Control machines, or preventing webmail abuse, we've got you covered.
Easy to manage
Traffic Control is managed through a centralized console – high performance clustering is standard right out of the box. Powerful log indexing and search means faster response times and reduced help desk costs.
Integrates with everything
Whether the goal is reducing inbound spam traffic or stopping abuse of webmail systems, Traffic Control's policy delegation functionality enables fine-grained control of email delivery policy by other systems such as customer configuration databases.
