3 Installation for Microsoft Exchange
2003
3.1 Introduction
GFI MailEssentials installation depends on how your network is
configured for Exchange 2003. You can install this product on:
 The Microsoft Exchange 2003 server: This setup is typically
used to filter email spam on the mail server that is configured to
receive emails directly from the internet.
 The SBS 2003 server: This setup is used to filter email spam on
the SBS 2003 server, which uses Microsoft Exchange to receive
emails directly from the internet.
 The mail relay server: This setup is commonly used to filter spam
in distributed email infrastructures., especially those running a
DMZ. In this environment a dedicated machine (also known as a
gateway/perimeter server is set to relay emails to another mail
server (running Microsoft Exchange). GFI MailEssentials is
installed on the gateway/perimeter server so that email spam is
filtered before reaching the mail server. This setup reduces
network traffic, email storage and processing requirements on your
mail server.
 Microsoft Exchange Server & IIS Clusters: This type of
installation is commonly used to filter spam within environments
where clusters are used as disaster prevention and recovery.
