I'm far from an expert in DNS or Linux, but I think I have things setup properly.
nslookup with 'set q=mx' and fed 'foostuff.com' returns the following.
> foostuff.comHowever, I still get the following error when running the install.sh script.
foostuff.com mail exchanger = 10 zimbra.foostuff.com.
DNS ERROR resolving MX for zimbra.foostuff.com
It is suggested that the domain name have an MX record configured in DNS
Change domain name? [Yes]
If I continue the installation the services start properly. I'm not sure if it's a false-positive. I've not tried to configure things much yet thinking that I should resolve the installation error before getting too deep into configuration.
root@zimbra:~# cat /etc/hosts
192.168.0.10 zimbra.foostuff.com zimbra
Oh yea, Latest version of OpenSource Zimbra on Ubuntu 6.06.1-server.
