ESET, the leader in proactive threat detection, has announced ESET Mail Security 4 for Microsoft Exchange Server is now available for public beta testing.

ESET Mail Security 4 for Microsoft Exchange Server significantly improves upon the mail security functionalities of its predecessor, ESET NOD32 Antivirus for MS Exchange Server.

ESET Mail Security 4 for Microsoft Exchange Server keeps your network safe from spam and email infections. At the core of ESET protection is the NOD32 Antivirus 4 scanning engine — fast, accurate and light on system resources — so you don't have to trade system performance for security. Armed with ESET's latest self-defense features, ESET Mail Security 4 safeguards your business from malware seeking to disarm or delete your protection in order to compromise your data.

Mail Security 4 stops email-based malware and spam at the transport layer. Preset profiles make it easy to select the optimal setting between spam detection and performance features. Greylist technology and other spam filters stop unwanted messages from reaching end-user mailboxes. The graphical user interface simplifies setup for advanced features like individual mail recipient quarantines and ThreatSense scanner thread pool tuning.

Key enhancements include:

*Greylisting and several other antispam techniques work together to block unwanted email at the mail server
*Preset and customizable antispam profiles to deliver the desired balance between detection and performance
*Microsoft Exchange Server 2010 support ensures compatibility with the latest mail server technology
*Flexible rule-based quarantine of potentially infected messages and spam is configurable by email recipient address
*Mail server performance monitoring and statistics (with graphical visualization) allows administrators to quickly identify problems
*Timesaving system tools, ESET SysInspector and ESET SysRescue, simplify system diagnosis and cleaning of heavily infected systems
*Improved GUI simplifies user experience
*Self-Defense ensures protection does not degrade in the case of targeted attacks on ESET software
*Built on the same ESET NOD32 Antivirus 4 engine for the most effective proactive protection

The beta test version is a precursor of the final product without full functionality and documentation. It is intended for experienced users and should not be installed on computers that perform critical tasks because it may cause errors or crashes.
