Not wishing to share may data with google or any other 3rd party I've
started looking at having some sort of "cloud" server software on my Linux (CentOS 5.8) based server.
Principle requirements are to be FOSS, sync calenders and contacts between Android mobile devices, file sharing would be nice but not essential and a "user friendly" (local) web interface to calenders/contacts/files.
I like DAVdroid as it can sync calendars and contacts within a single
account rather than having the "clutter" of separate calDAV and cardDAV accounts. The DAVdroid site
ownCloud, Posteo, Radicale, SOGo, eGROUPWARE, MyKolab.com, contactzilla, Baikal, iCLOUD, OS X Server, zimbra, DAViCAL, Yandex, Group Office, Cozy Cloud, FastMail....
I've only installed and played with ownCloud so far, that works syncing calendars and contacts with the Android devices I have via DAVdroid but the web interface leaves a little to be desired.
Posteo web site appears to be single language that isn't english... Baikal is server only, no local web interface to calendars etc. Cozy Cloud doesn't do files, yet... Some of the others I've looked at appear to be aimed at the corporate market and a little heavy weight for us.
Has anyone played with SOGo
