Zimbra is an Enterprise class mail server. It requires a lot (1GB+) of memory. We recommend you have a dedicated server in order to run it.
To install it just mention you need it when your order a server from us and we will go prepare it for you.
Grab zimbra from http://www.zimbra.com/community/downloads.html
(e.g. the Red Hat Enterprise Linux 4 (.tgz) url). You probably do not want to get Zimbra via svn/subversion.
# else the pop3 / port 110 server else the Zimbra
# apache tomcat process will complain about not being able to listen on port 110
chkconfig --del dovecot
apt-get install compat-libstdc++* libidn curl fetchmail
# else the Zimbro apache tomcat will complain
# about not being able to listen on port 80
chkconfig --del httpd
Follow the instructions at:
You will probably need to copy a jni library to your trusted java path:
cp /opt/zimbra/lib/libzimbra-native.so /usr/java/jdk/jre/lib/i386/
Restart your server and then log in at https://yourip:7071/zimbraAdmin . Use admin as the username. Use the password you set during the install process.
