[Dovecot] [OT] MS Exchange Alternative?
Just wondering if there's an open source Linux alternative to MS Exchange so that all the features of outlook work?

Horde groupware? www.Horde.org
I tried horde but for real Outlook connectivity, which is done via ActiveSync, my experience ist not so good; then and now I got contacts that kepte replicating themselves and dates that would not show up in Outlook or the Web GUI. If you use it with Thunderbird or the like, different story. JC

Most part of it is open source; the outlook connector ist closed source however and requires a license fee for more than three clients. It uses MAPI to connect to Outlook, unlike many other solutions that do calendar syncs etc. via the ActiveSync protocol. Zarafa is a completely different thing than dovecot, however; it stores all mails in a MySQL database.

Future versions of Zarafa will hopefully serve IMAP protocol via Dovecot. :)

If they'd do that, it would be great because that's *the* reason I'm not running Zarafa.
Last time I tried the Zarafa IMAP server, which is some years ago, I was converting email locally via IMAP, just to see how Zarafa worked and behaved. The conversion would hang at random times, and it's IMAP server was so slow compared to Dovecot that I didn't want to use it.

So does SOGo, no plugin required for Outlook. There is an extension for Thunderbird+Lightning, and it also supports most every mobile client out there.... and it uses Dovecot for the IMAP server *now*, and also includes OpenChange and Samba4. It is also supposed to be *very* lightweight, and can integrate with most any other backend you may be using. We currently use PostfixAdmin for managing email users, and we'll be able to happily keep using it for as long as we want after the migration.
We will be migrating to SOGo (using Thunderbird+Lightning+Google Calendar now) very soon, and we are fully expecting to leverage the fact that SOGo includes Samba4 in the future, so that when the time comes for another Microsoft Server Upgrade, we will instead 'upgrade' to Samba4, and demote our older 2008R2 servers to member servers - if we keep them around at all.

We've used SOGo for the last three years and we deployed it at various locations - starting from 3 up to 30.000 users. SOGo is stable, the company behind SOGo knows what they are doing.
If you plan to migrate a SIEVE configuration you need scripting skills or you will end up adding them all by hand. SOGo currently stores SIEVE rules in its database and writes them into a .sieve on request. It's a one way road. That is actually the onle downside I can think of.

Try SoGo (http://www.sogo.nu/english.html) together with your basic mail software (e.g. Postfix/Dovecot).

Keep in mind that many solutions out there like Zarafa and Open-Xchange are not free (though they are open source).
On the other hand, SoGo and Horde are free.

Hey Marc,

Open-Xchange. They have a module called OLOX2 that enables you to make MS Outlook think it's connected to a Microsoft Exchange. So syncing of mails, calendar and contacts as well as global address book.

If you are into building the system, you can run an IMAP server and a caldav server. Davical gives shared calendars and shared address books, as well as a todo function that nobody every seems to use. In terms of limiations; for outlook you need a 20 euro plugin to support caldav and outlook is a terrible imap client, thunderbird doesn't support the shared address book thing yet, everything works as expected in evolution. Androids and iphones work, but you need something like a funambol server to support blackberry and other super-proprietary mobile devices. You can also add other features to make it shine a little brighter than an exchange server, such as openupload or webdav storage. And, if you really want a windows networking environment, all of this stuff can be made to authenticate against Samba4 active directory...
