1. Introduction
ESET Mail Security 4 for Microsoft Exchange Server is an integrated solution that protects mailboxes from various
types of malware content including email attachments infected by worms or trojans, documents containing
harmful scripts, phishing and spam. ESET Mail Security provides three types of protection: Antivirus, Antispam and
the application of user-defined rules. ESET Mail Security filters the malicious content at the mail server level, before
it arrives in the recipient's email client inbox.
ESET Mail Security supports Microsoft Exchange Server versions 5.5 and later, as well as Microsoft Exchange Server
in a cluster environment. In newer versions (Microsoft Exchange Server 2007 and later), specific roles (mailbox,
hub, edge) are also supported. You can remotely manage ESET Mail Security in larger networks with the help of
ESET Remote Administrator.
While providing Microsoft Exchange Server protection, ESET Mail Security also has tools to ensure protection of the
server itself (resident protection, web-access protection, email client protection and antispam).
1.1 What's new in version 4.3 ?
Compared with ESET Mail Security version 4.2 the following novelties and improvements have been introduced in
the version 4.3:
New logs for Antispam and Greylisting added - both include detailed information on messages processed by the
Antispam or Greylisting protection. The Antispam log includes also detailed reasons for classifying messages as
SPAM.
Automatic exclusions - Increase overall stability and smooth operation of the server. Defining whole sets of
exclusions from scanning by antivirus protection for specific server application and operating system files is now
just one click away.
Message categorization by spam score value - Administrators can now specify spam score ranges to customize
which messages will be categorized as spam, in order to fine-tune antispam filtering.
Merging of licenses - ESET Mail Security allows you to use several licenses and by that expand the number of
protected mailboxes.
