My Zimbra is running well before, but recently, I create a new email account, it can send/receive internal email OK. send email to external is OK.

But can't received any external email.

I setup one MTA server and one store server. Check the mta log:
Aug 29 15:49:36 mta postfix/smtpd[15266]: NOQUEUE: reject: RCPT from m13-201.163.com[]: 550 5.1.1 <carol.ye@xxx.com>: Recipient address rejected: xxx.com; from=<fish@airprice.com> to=<carol.ye@xxx.com> proto=ESMTP helo=<m13-201.163.com>

On store server log, I can't found any information about it.

It looks like when I create the new account, But it can't be copied to MTA. How I can handle it?
