What about Zimbra or Scallix?

Zimbra looks impressive! Anyone here running it?

We have Zimbra running with several hundred mail users on a CentOS 4.5 system (it wouldn't run on CentOS 5 when we started the project).

It works well, but does not play nicely with others, basically taking over major parts of the system, postfix, openldap, IMAP, etc., and does so in a manner that makes it difficult to integrate in some systems (e.g. put it behind a postfix, amavisd, clamav, spamassassin system that I can keep current with the Latest & Greatest updates, and configure DNSRBLs to my liking).

I like to think I have better solutions for e-mail handling than Zimbra, and much prefer to use them unless there's an absolute demand for Exchange functionallity.

I won't get into the licensing religious wars, nor do I mind paying for proprietary solutions if they do a better job for my paying customers than I can do with open source.

The horde/imp/kronolith/... family of programs, provide good functionallity, but, like any webmail solution, have some basic limitations due to the web interface.

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...

It does NOT fit the definition ... mainly because of the Attribution requirements ... if it DID fit the defination, it would be approved by the OSI. It was rejected as an OSI license. Here is one discussion:

http://linuxgazette.net/148/moen.html

Really though, whether or not it fits with YOUR definition of "Open Source" or Simon's or mine is not relevant ... the only FACT is that the OSI has not approved either license (and both asked for approval). What that means to each user is not really relevant to this list. The OSI only matters to people who think it matters, and to others it does not.

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

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.

We use exchange 5.5, in a virtual instance, with samba. Best solution for our enterprise so far.

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.
