That really doesn't prove anything other than you can ping an outside server.

Then you should post the output of the following commands to show that your DNS is OK (run these on the Zimbra server):

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain.com any
dig yourdomain.com mx
host `hostname` <- run that exact command with backticks not single quotes

Your hosts file is incorrect, this line:

127.0.0.1 localhost

Should look like this:

127.0.0.1 localhost.localdomain localhost

as per the Quick Start Installation Guide.

Also, after changing to the above hosts file I still have the same error during installation.

The DNS server at 208.67.222.222 is not returning the same information as the other server, you have an incorrect A record (or no A record) in that server. If you're going to use two server they should have identical records in them.
