Ok, here's what you need to do:
Uninstall and remove everything so we can start from scratch.
Download v 6.30.4 here:
http://download.zarafa.com/zarafa/drupal/ondemand.php?version=6.30.4&distro=rhel&distroversion=4&arch=i386&type=1(DO NOT USE 6.30.5, its not working on SME Server (yet?))
Copy the file to your server and extract: tar -xzvf zarafa-6.30.4-rhel4-i386.tar.gz
install all the rpms with:
yum localinstall *.rpm
Enable InnoDB engine with:
db configuration setprop mysqld InnoDB enabled
expand-template /etc/my.cnf
sv t /service/mysqld
download this file:
http://netkeeper.huge.co.za/smeserver-zarafa-0.9-4a.noarch.rpmand install:
rpm -Uvh smeserver-zarafa-0.9-4a.noarch.rpm
Then do:
/etc/e-smith/events/actions/zarafa-install
signal-event post-upgrade; signal-event reboot
and zarafa is installed!
to create a new user do:
/etc/e-smith/events/actions/zarafa-create-user
use the zarafa-admin command to list and manage users.
Let me know if this worked for you, im sure it will.
