Message Analysis

NoSpam Service uses numerous traditional techniques for spam detection in combination with a variety of next-generation approaches for message analysis. Within this wide spectrum of tests, generally no single element will by itself classify a message as spam — thus avoiding the false positives associated with simpler approaches — while the breadth of analysis results in an industry-leading detection rate for junk email.

• Authenticity Checks
• Message Fingerprinting
• Heuristic Rule Set
• Public and Private Blacklists
• Extensive URI Databases
• Domain History and Reputation
• Self Learning Bayesian Engine
• Real-Time Message Source Analysis
• User-Based Message Profiling
• Customizable whitelists and blacklists

Message Handling

With the goal of minimizing the amount of time an administrator or email user needs to spend managing their junk email, NoSpam offers several options for handling of detected junk mail.

• Drop
• Tag and forward
• Redirect
• Quarantine
• customers can opt to receive periodic message digests

True Continuity

Email is a critical business tool. For most organizations, inability to access or use email – even for a limited time – has a substantial cost in productivity and often in revenue as well.

• First, in the event that the customer's mail server is temporarily down or inaccessible, NoSpam acts as a message queue. No messages are lost, and people who send email to that organization don't receive error messages; NoSpam simply stores those messages and delivers them once the customer's mail server is back online.
• Second, in the event that a customer's mail server is down or will be down for any extended period of time, NoSpam can provide on-demand, full-fledged backup mail service to that organization.

Seemless Integration

As a managed service, NoSpam is deployed at the gateway to a customer's network and is compatible with any email infrastructure -- whether that is a heterogeneous multi-server environment common to ISPs who have grown through acquisition, or a single in-house mail server at a given organization.
