Hello.  We are running a Windows Network and have one MS Exchange Mail Server.  We need to have a backup and need inexpensive solutions.  We looked into purchaing a 64 bit server and loading MS Exchange 2007 Enterprise Edition, however my CFO says it is cost prohibitive.  How can I have a realtime concurrent email backup server running at the same time on my network?

Email Redundancy

An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A web application that provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Email clients can also have other systems, like calendars, notes and contact managers.

Email Clients
