Sunbelt Software's Ninja Email Security Version 2.1 provides a layered security approach for email inspection, cleansing and management in Microsoft Exchange. By using multiple scanning engines for antispam and antivirus while simultaneously integrating other email security rules, all treatment of incoming messages occurs at the server instead of at the end-users' workstations. No additional client software is necessary.
The upgrades to Ninja Email Security Version 2.1 deliver improvements in spam detection with the addition of four new antispam engines to protect against the latest variants of new spam.
Ninja Email Security Version 2.1's new features include the following:
- A Sunbelt Dedicated Image-Spam Engine: A dedicated image-spam engine uses proprietary technology to add an extra layer of detection for spam images embedded inside email messages.
- SURBL: A dedicated SURBL engine that checks email content against spam real-time URL lists of known spammer domains.
- An enhanced Cloudmark Engine: An updated version of the Cloudmark Authority antispam engine provides enhancements to further improve the detection of the latest spam variants including image and PDF spam.
- Sunbelt Advanced Spam Filter: A new antispam filtering engine recognizes the latest spammer tricks and techniques by recognizing suspicious misspellings and other unique spam-identifying characteristics. The filter is tuned to detect specific spammer tricks, allowing it to catch new types of spam -- such as embedded content, HTML and foreign language spam -- while ignoring general factors that can generate false positives.
