Ok it works, thx for the info. I will write it down for other people as well.
Please correct me if there is a better/safer way to do this. I'm still learning this stuff so.
# cd /usr/share
# service zarafa-server stop
# sudo mv /usr/share/z-push /usr/share/z-push-orig
# sudo wget
https://launchpad.net/~bencer/+archive/zarafa/+files/d-push_2.0.1.orig.tar.gz# sudo tar -zxvf d-push_2.0.1.orig.tar.gz
# sudo mv /usr/share/d-push-2.0.1/ /usr/share/z-push
# cd ..
# sudo mkdir /var/lib/z-push ( if not needed the server will say so )
# sudo mkdir /var/log/z-push ( if not needed the server will say so )
# cd /var/log
# sudo chmod 777 z-push
# cd /var/lib
# sudo chmod 777 z-push
# service zarafa-server start
That's it , works like a charm. You need to remove the accounts from your devices ( phone, pad ) and install them again.
