The Best Open Source Alternatives to MS Exchange
(Dec 20, 2008, 20:03 UTC) (5514 reads) (6 talkbacks) (feedback)
Intranet Journal: "No matter what you might happen to think of it, the fact of the matter is that we live in a Microsoft- driven enterprise environment. Whether this is for better or for worse, the fact is that some legacy ways of doing things are just so embedded, than even attempting to try an alternative is laughable. All of that being said, I believe that enterprise-level groupware functionality is not one of those legacy applications. In short, I believe in groupware offerings outside of the halls of Microsoft. And it is in this spirit, that I will now take on the task of creating a list of the best open source alternatives to Microsoft Exchange."
