On which machine should I install GFI MailArchiver?

GFI MailArchiver should be installed on a machine that forms part of the Active Directory domain whilst taking into consideration the following points:

Email flow experienced by your servers
Machine hardware and software specifications
Need to archive email from multiple sources concurrently

For example, if you only need to archive email from one mail server source, for instance Exchange Server, and the server is handling the email flow on your network and still has spare processing capacity, then you can choose to install GFI MailArchiver on the Exchange Server machine directly. On the other hand, if you want to archive email from multiple mail servers, including non-Exchange Servers using the IMAP protocol, we suggest that you install GFI MailArchiver on a separate machine.

NOTE: GFI MailArchiver does not require a dedicated machine when it is not installed on the mail server. For example, you can, install GFI MailArchiver on machines running other applications such as GFI MailEssentials or GFI MailSecurity.

The machine on which you choose to install GFI MailArchiver needs to have Internet Information Services (IIS) and the World Wide Web Service installed and running, with ASP.NET registered, since GFI MailArchiver needs to create a virtual directory to host the GFI MailArchiver web interface.
