For my hosting activities I have SOGo now running for a while, and I must say that it works pretty nicely. It offers the basic groupware functionality without forcing you to use their own authentication implementation or email (IMAP, SMTP) server, so it integrates very well in my current setup of OpenLDAP, Postfix and Dovecot.

I have been evaluating competing solutions like Horde, OpenXChange and Kolab, but they always imposed their own authentication services, rigid email setup, or out-of-distribution packages. Next to that, the provided web client usually looks horrible, or the service didn't provide modern standards like CalDAV and CardDAV.

...

With SOGo, you just tell it where the user accounts are stored and how they can authenticate. Basically the same information I give to Postfix and Dovecot. That's how it should be. The only thing extra that needs to be done when I add a new domain is adding the domain to its config structure, the rest works automagically. Hopefully the SOGo people will add a feature that it lifts the domains it should handle from LDAP, then even this small extra step is not needed anymore.

SOGo has a very nice web interface for reading email and managing your calendar(s) and address books. The cleanest solution I have seen so far. It reads your vCard address books, shows you multiple calendars, and gives you popup reminders for calendar events. It also allows you to use multiple email accounts in a single view, similar to what Thunderbird offers.

For Thunderbird, there's the Lightning plugin , a CalDAV plugin that integrates the calendar right into your Thunderbird client.

There are a few bugs in the lightning plugin, that prevent the CardDAV addressbook integration to work. Hopefully this will be resolved quickly.
