Zimbra is an open source alternative to Microsoft Exchange. It uses a number of open source products, namely Postfix, Tomcat and OpenLdap. It can interact with Active Directory and other directory structures. It also offers a pretty extensive AJAX enabled web interface.

It offers most of the features offered by Exchange:

  • Email
  • Contacts
  • Shared Calendaring
  • VOIP integration
  • Mobile access with activesync push sync and Blackberry Enterprise Server connector
  • MAPI, IMAP, POP, iCal iSync Access
  • Extensive web interface

It offers both an open source and commercial version, and is now owned by Yahoo.

Ahh...the white whale of open source, the Exchange killer. There's no shortage of competitors:

And, for those that aren't necessarily looking for free (in either sense), but just don't like Microsoft or Exchange:

There is an Exchange-like open source project called Open-Xchange.

It is a messaging and collaboration platform combining common free software packages, open standards and web services. Open-Xchange Server is available as proprietary software and as a community supported open-source software (GPL 2) package.

We evaluated http://www.kerio.com/ when we moved away from Exchange 5.5, and it seemed quite polished.

It is not open source, but the community edition of Scalix is free-as-in-beer. Never used it myself but I've heard really good things about it.

I've not tried it personally but take a look at http://www.zimbra.com/

It's dual licensed but the opensource one might give you everything you need.
