you might want to hold off on Zimbra since it's likely to become a
Microsoft owned product.

I personnaly like the combination: Postfix, Mailscanner, Group-Office.

Group-office has the functionality i need (email, calendar, calendar
sharing, tasks, filemanager, addressbooks, projectmanager etc...
Yet is quite simple to setup and use...
In the professional version there is also a synchronisation option to sync
with outlook...

Authentication can be performed on database, email or ldap...

eGroupware is another one, similir to group-office but with much more
functionality.

Kollab is pretty decent although it's a bit particular to install.

And don't forget horde-groupware webmail edition, you can use your own
imap server (cyrus-imap in my case) to authenticate users:
a good groupware.

We're running the Community edition of Scalix. Easy to setup, easy to
administrate. Fully integrates with Outlook and has an AJAX webmail app
as an alternative. On the down side it's a bit server heavy (as Java
tends to be) and the IMAP server is a bit buggy, but if you use Outlook
then you'll avoid that.

What about Open-Xchange they have two open source versions. It could be a challange to compile OX, then you could use the install CD (iso-image) from NnorTuX http://www.nnortux.no

Both not Open Source
Scalix uses Scalix Public License (SPL) and Zimbra uses Yahoo Public
License (YPL) - both crap licenses and not OSI approved.

Well, that's the closest you gonna get. Open Exchange, eGroupware, etc
doesn't even come close to MS Exhange.

Open Source does not depend on the license. You've been drinking the
GPL koolaid too long if you think this is the case.


Without turning this into a religious debate that I can see on the
horizon, you should really read this:

http://www.opensource.org/docs/definition.php

Comparing the Zimbra licensing (http://www.zimbra.com/license/) to the
definitions in the link above, Zimbra seems to fit the definition of
Open Source...


The Scalix license (http://www.scalix.com/community/opensource/licensing.php
) may also fit the bill...

Well, the first part of your statement is debatable (that they are not
"Open Source"), but the second part is fact .. they do not use OSI
approved licenses. So, if your definition of "Open Source" is an OSI
approved license, then they are not open source.


What's more, in all of these cases full outlook capability is not
provided in the "Free" version anyway.


Outlook calender/meeting functionality requires (in almost all the
solutions) a really non open source (proprietary and not compilable)
program to make use of the proprietary outlook/exchange interface called
MAPI. Most of the free versions of these mail systems use IMAP, with
will not properly be used by outlook to do calander functions ... and
they charge for the outlook MAPI client, which will allow for outlook
calender/meeting functions.
