Before you start, *setup your DNS*. Zimbra install is very sensitive to correct DNS setup, particularly /etc/hosts and forward resolution of the hostname you are installing on as returned from hostname. Search wiki/forum for correct DNS setup.

change /etc/debian_version to 3.1
apt-get install sudo curl fetchmail libgmp3c2 libssl0.9.7 libdb3
chmod a+rwx /tmp

tar -xzf
cd zcs/

clean out previous attempts:
sh install -u
rm -rf /opt/zimbra
rm /tmp/install*
rm /tmp/zmsetup*
rm /tmp/*zim*

change util/utilfunc.sh
if [ $PLATFORM = "UBUNTU6"]; then
to
if [ $PLATFORM = "UBUNTU6" -o $PLATFORM = "DEBIAN3.1" ]; then

sh install.sh

Strangely detects hostname as domainname (never quite understood why it does this). Select 'Yes' for "Change domain name", change to domainname "domain.com" instead of "host.domain.com"

If you haven't set your MX yet, ignore (you'll need to set this later but its fine for install):
DNS ERROR - none of the MX records for ijichi.org
resolve to this host
It is suggested that the MX record resolve to this host
Re-Enter domain name? [Yes]
^^ Choose "No"

Install Menu: Choose 6 for zimbra-store, 4 for Admin Password, enter password, 'r' or for previous menu, 'a' to apply, Enter for next two questions:
Save configuration data to a file? [Yes]
Save config in file: [/opt/zimbra/config.15938]
Then 'Yes' for: The system will be modified - continue? [No] yes

Checkout output carefully for *any* errors, should install fine.

You can change /etc/debian_version back to 4.0 after install but you'll have to change it for each upgrade
