This subject has been covered and answered many times in the forums, please search for the troubleshooting steps and post the details. If the installer tells you it can't find an MX record then your DNS is not set-up correctly.

Then you type "No"...

"No"

Then Zimbra will start install...

I would also suggest, you may want to go with ZCS 5.08 and not 4.5.x. Some great new features in the 5 branch. Also, if I remember 4.5.7 had a bit of a java cpu load issue (it may not have been 4.5.7, but it was around then).

Actually, you should set-up the DNS records correctly beforehand - replying 'no' will give you a domain with the FQDN of your server not the correct domain name. i.e. you get mail.domain.com instead of domain.com.
