Reading all your posts I reckon you still have a issue with your DNS configuration, and the fact that you have run commands like ./opt/zimbra/libexec/zmmyinit means you have broken the natural installation order. So, would you please post
Code:
cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain mx
dig yourdomain any
host `hostname` <- note backticks and not single quotes
Once we have checked all these for you I would recommend un-installing ZCS again and also remove /opt/zimbra/* so that everything is created again from scratch.
