Symantec Mail Security™ for SMTP provides high-performance, integrated mail protection against virus threats, spam, and other unwanted content at the earliest point of network entry, the Internet email (SMTP) gateway. Symantec’s extensible NAVEXTM antivirus technology defends against new and known viruses, while attachment and subject line blocking features provide hour-zero responses against emerging threats. In addition, a Mass-Mailer Cleanup feature eliminates worm-infected messages. With integrated LiveUpdate™ functionality, virus definitions can be deployed across the enterprise without stopping scan services or incurring server downtime.

Basic spam tools include an antispam heuristics engine, custom filtering rules, real-time third-party and custom blacklists, and various whitelisting techniques to maximize detections and minimize false positives. Auto-generated whitelists automatically capture mail domains that are trusted by the organization, simplifying the task of generating a comprehensive whitelist. In addition, flexible spam handling allows administrators to insert custom tags into spam messages, assign different dispositions based on spam score thresholds, and distribute tasks associated with controlling spam. Unwanted content can be filtered by message characteristics such as subject line, attachment, message size, and words and phrases in body text.

An optional Symantec Premium AntiSpam add-on subscription service, powered by Brightmail technology and response, enables organizations to achieve high detection rates of over 95% and the industry’s highest accuracy rate against false positives (99.9999%*). Multi-layered spam prevention, with Symantec Mail Security, leverages over 20 filtering technologies, including spam signatures, heuristics, reputation filters, language identification, and proprietary methods, with automatic updates occurring every 5-10 minutes. No new software or hardware is required, and the service requires no additional IT administration or tuning once deployed.
