I have enable DNS lookup in MTA tab.

This has been covered several times. Have you searched the forums about this problem?

Do you have any firewall/SELinux installed or activated? What is in the Zimbra logs, any errors?

Does your ISP block port 25?

but I cannot send email in the outside subnet.

Pls help...

Thinking about this, I'm not sure I really understand the problem. Are you saying you can't send mail externally? If so, according to this post you can.

Please explain the problem to me again.

Cannot send email via internal network

Remark:
88.888.88.88 = mail server ip (zimbra.com.cn)

Is this 'zimbra.com.cn' your domain name? If it is then it doesn't point to any mailserver, you have no MX records set-up - that's why you can't deliver mail. Have a look at this page.

Is ok?

[phoenix]

No, it's not OK. Where are you getting that DNS information from? Do you have your own DNS server installed?

Is this 'zimbra.com.cn' your domain name? If it is then there are no public DNS records for your domain name - that's the problem with your mail delivery.

Have a look at this DNS check

P.S. i can send email to zimbra@zimbra.com.cn via external webmail, but cannot send email to external.

1) i'd wager money you're not using smtp auth.
2) your helo isn't an fqdn so will probably be rejected anyway
3) i can't imagine zimbra are going to be very happy with you re: the domain name.
