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.

Compatible with Microsoft Exchange Server (versions 5.5, 2000, 2003, 2007 and 2010).
