Star Can Open Source Replace Microsoft Exchange?

Features, Office Everyone knows that Microsoft Exchange is expensive - but ubiquitous â€" and plenty of open source projects and vendors have been trying a variety of technical approaches to replace it. While none is yet a drop-in replacement, a PC World article looks at ways that some administrators can get a cost advantage by switching.

With Zimbra, you pay that price per user every year, so over 5 years, it is more expensive than Exchange in per user costs.


There are a number of solutions that on the very face of it appear to be more attractive than Zimbra.

Apart from those already mentioned, here is yet another possibility:
http://www.citadel.org/doku.php
"Citadel is here today and is actively maintained - it's neither vaporware nor abandonware.

Citadel is true open source (GPL) software. Unlike other groupware servers, it isn't a cut-down version of an expensive proprietary 'pro' version. We make our very best work available to everyone on the same terms."

No per user fees at all.

"Microsoft Exchange, Meet Your Replacement

The time has come to consider moving that expensive, high-maintenance Windows system to a sleeker, more robust Linux system.

...

Although migrating users from applications such as Microsoft Office to OpenOffice.org is generally an intuitive task, the 800-pound gorilla that's keeping you up at night is e-mail and groupware. How are you going to provide and manage Microsoft Outlook-like functionality to the masses? In a word, Citadel. "
