    Open-Xchange is pretty good. It's got backing from Novell so expect to see some development (i hope!!)

    I know of a free mailserver but not as good as exchange, known as hmailserver

    Hope this helps.

    I have implemented Scalix on several sites, and it is a descent replacement. Has some pros and some cons, but was surprisingly good.

    I use a qmail + courier-imap backend with Horde Groupware Webmail Edition for a web interface

    Most distro's have a wiki for qmail install and the Horde docs are pretty easy to follow.

    What exchange features are you looking for?

    Accepted Solution

    shared calendars(Kronlith) folders(IMAP) contacts(Turba)

    These are all parts of the Horde Groupware Webmail Edition. To get it working you should install Apache, MySQL, PHP and your flavor of email server with IMAP support. Once that is done Horde is installed with a simple copy of the PHP project into your web server directory. Depending on what else you are hosting you could even put it on a virtual host like . I have mine running under SSL just fine as well, something you should consider for a production system.  As I stated above, most distro's have good Wikis for mail installation weather you choose qmail, postfix... just be sure you install the IMAP support as well.  Some guides even include clamav and spamassassin to help protect the Windows clients.  I am running under Gentoo and the install docs are here for the mail system --->

    qmail --
    postfix --

    I suggest doing a test install on a VM or spare box to get the bugs worked out. The first time I installed one I read a lot of docs but after a couple of installs it is not so intimidating. Be sure to follow a PHP guide to be sure you have it configured safely for a production system.  (there are many others)

    This suite is webmail-based, right? Am I right by saying that there is no Outlook interoperability for anything beyond imap mail ?
