The historical stumbling block for replacing MS Exchange has been Microsoft’s closed, proprietary MAPI protocol
HINT: MAPI protocol ?! Short for Messaging Application Programming Interface, a system built into Microsoft windows that enables different e-mail applications to work together to distribute mail. As long as both applications are MAPI-enabled, they can share mail messages with each other (from WEBOPEDIA) .
- In 2007 European union orderd microsoft to open its serverl protocols . In order that MS open protocols and MAPI
- Afer that samba 4 released , it support Microsoft protocols and MAPI , from this time samba become active alternative . MAPI is key to natively supporting MS Outlook, and to interoperability between Exchange and other groupware and mail servers.
- Is another commercial many-bells-and-whistles, open source-based server with proprietary add-ons. It includes all the usual goodies: email, Webmail, shared folders, shared contacts, calendaring and scheduling, instant messaging and mobile devices, plus Outlook sync.
- Zimbra’s Web interface is called Zimbra Desktop. Zimbra Desktop supports all of Zimbra’s features, and it supports syncing external accounts such as Gmail, Yahoo, or any POP3 or IMAP mail. In fact, a feature common to all of the groupware suites in this article is they have excellent Web-based client interfaces, so you don’t need standalone clients like Outlook or Evolution. If you can wean users away from their beloved Outlook you can make administration a lot easier, and not have to hassle with the cost of using special Outlook connectors..
- based in the Netherlands, also offers native Outlook support. Zarafa is designed to add on to your existing mail server and WebDAV server. An easy way to get acquainted is to set up a Fedora Linux test server, because Zarafa is included in Fedora.
What Sets Linux Groupware Servers Apart?
When you do a Web search for “linux groupware servers” you’ll find many more, such as Scalix, Horde, eGroupware and Kolab — all with similar feature sets. Underneath you’ll find much of the same software, such as Postfix, Dovecot, Apache, PHP, MySQL, Squirrelmail, OpenWebmail, Courier and Linux. The differences are in integration and polish, ease of installation and management, support for proprietary devices or protocols, support for extensions (like Zimlets), and licensing and support costs. It is a feast of good choices.
