Hey Karanbir

I'm trying to achieve a simple fail over solution, for a small rural 
clinic, about 700KM's away, which we have sponsored, so there's no money 
involved and I can't afford / justify exchange (don't want to go the MS 
route in anycase), Zimbra or any of those.

For fail over on the webserver & samba, the heartbeat + rsync works 
well, but I don't know where to look for the email stuff. I don't need 
anything fancy, but a shared calendar & address book would be great. 
It's a 10 user network
