You zip file attachment is unreadable. You are also using a domain name for your MX record it should be a FQDN (e.g. mail.qualipso.org.cn), you are also using an IP address for your external records and that should also be a hostname. You should fix your external DNS records.
Please read the DNS In A Nutshell ports in the forums (search for that) and the Split DNS article from the wiki, they both tell you how to set-up a Split DNS correctly. Once you've done that you can check the configuration by running these commands on your Zimbra server:
host `hostname` <-- type that command exactly as you see it with backticks not single quotes
dig qualipso.org.cn mx
dig qualipso.org.cn any
