There are two very viable open source replacements for Microsoft Exchange. I highly recommend the use of these products if you are seeking a replacement for Microsoft Exchange.

Introduction

The goal of the Open Source Microsoft Exchange Replacement Platform ® (OSER Platform ®) is to provide a replacement for Microsoft Exchange that is:

Open Source. Mostly GPL however other licenses are used for various components.
Equally functional. For more information on this please see the Features link above.
Free in terms of price and freedom. However sponsorship is very much appreciated. Paid support is available.

It is a major undertaking that couldn't be done without the use of existing high quality open source software. For more information please see the links at the top of the page.
