I read in another thread about how to enable SMS notification, very nice very cool.

zmprov mc default zimbraFeatureCalendarReminderDeviceEmailEnabled TRUE

Had I not read that thread I wouldn't have gotten this nice little gem Yeah baby

Now, how do I find out the laundry list of things/features that can be enabled in the FOSS edition ?

How do I find the list of all the things/features that exists for that matter ?

Would be nice to read and know and decipher what you want on or off.

For example, I read in the help Preferences area, mobile device sync. I guess that's the paid version only right ? I dunno for sure. Is it something we turn on.

Hopefully clear
