Finally, a scalable groupware solution that matches the offerings from big vendors.

you will obtain the event with a summary “foo” in the foo.EML file. The EML file is actually an RFC 2821 message with a text/calendar part. That part can be extracted and imported into SOGo easily. WebDAV is de-emphasized in Microsoft Exchange 2007, so hurry and migrate from it.

A similar approach can be used with Oracle Calendar. A demo program bundled with Oracle's SDK provides an excellent starting point for becoming familiar with the shared library named capi. With this library, you can retrieve a user's events formatted with the iCalendar standard. As with Microsoft Exchange, the migration process is simply to push all events in SOGo through WebDAV. The Oracle Calendar's only limitation is related to recurring events; even though a series of events can be identified clearly, there is no easy way to retrieve the original recurrence rule definition. This frustration surely will be attenuated by the advantages of SOGo, such as endless recurring events and a much more modern Web interface.


Standards, such as CalDAV and SyncML, finally have emerged that improve interoperability between native groupware clients and various servers. Open-source developers have proven their commitment in supporting those standards and created competitive alternatives to commercial solutions.

The Scalable Project always has followed the same motivation—to offer an open-source, scalable groupware solution that integrates nicely with the Mozilla PIM suite, while not neglecting mobile users. This article should help you get started with SOGo, so you can test its functionalities for yourself. Join the mailing list to discuss your experience with the developers.

SOGo 1.1.0 with SOPE r1660 compilation

SOGood's picture

just do apt-get install libmemcached-dev

I am having the same issue... Running on Ubuntu 8.04 64 Bit.

SOGO's compilation

Hello there,

Francis this is great tutorial!

However, you may need to update it as the option --with-gnustep in

   % cd ../SOGo-trunk
   % ./configure --with-gnustep --enable-strip --disable-debug

doesn't seem to exist anymore.

Then on my Debian Lenny machine, the GNUstep make is located in /usr/share/GNUstep/Makefiles/, no more in /usr/GNUstep/System/Library/Makefiles/

Finally, I still have an error during the SOGo's make :

   SOGoCache.h:29:36: warning: libmemcached/memcached.h: No such file or directory

Would someone knows how to resolve this issue ?

Best regards,

Good Tutorial

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
