I was looking through some tutorials on how to install Zimbra ZCS on Ubuntu.
Mainly I kept coming across this one.
I had two question related to the installation,
Zimbra only has an "Official Version" for Ubuntu 10.04 LTS. Can I load it on Ubuntu 11.04?
In the tutorial the writer talks about setting your internal DNS server with an MX record for zimbra. If I am only going use Zimbra for my external domain, do I need the internal DNS records?
I need to learn to read more. The DNS settings are explained in the tutorial.
