Just for my peace of mind run the following commands (on your zimbra server) and post the output:
Code:
cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain.com any
dig yourdomain.com mx
host `hostname` <-- type that exact command and use backticks not single quotes
What errors do you see in the l
og files when you try to start zimbra?
Just a minor point here, it's not recommended to install Zimbra on a VPS and it is recommended to install it on a 'real' server with a supported operating system. If you get it going in a VPS that's all well and good but it is not a supported platform, Zimbra works extremely well when it's installed on a recommended platform.
