兩個郵件伺服器，在其中一個做了alias轉發之後的問題。
郵件伺服器都是用的postfix+mysql+Courier-IMAP+extmail，想把部分發送到.com.cn伺服器的郵件通過alias錶轉發到.com同一個人的郵箱中。但是凡是使用.com郵箱往.com.cn發送的時候就會報下面的錯誤
<test@aaa.com> (expanded from <test@aaa.com.cn>): host
mail.aaa.com said: 554 5.7.1 <xxx@aaa.com>: Sender
address rejected: Access denied (in reply to RCPT TO command)
Reporting-MTA: dns; email.aaa.com.cn
X-Postfix---by-JRJ-Queue-ID: EF2C1E5CED
X-Postfix---by-JRJ-Sender: rfc822; xxx@aaa.com

Final-Recipient: rfc822; test@aaa.com

Action: failed
Status: 5.7.1
Remote-MTA: dns; mail.aaa.com
Diagnostic-Code: smtp; 554 5.7.1 <xxx@aaa.com>: Sender address rejected:
Access denied
也就是說，當用.com的郵箱xxx@aaa.com發送郵件到 test@aaa.com.cn后，轉發郵件到test@aaa.com。轉發后就會被拒絕，其他域沒有問題，該如何解決？
.com伺服器上Log
postfix/smtpd: NOQUEUE: reject: RCPT from mail.aaa.com.cn: 554 5.7.1 <test@aaa.com>: Sender address rejected: Access denied; from=<xxx@aaa.com> to=<test@aaa.com> proto=ESMTP helo=<email.aaa.com.cn>
.com.cn上LOG
postfix/smtp: 1099AE5CED: to=<test@aaa.com>, orig_to=<test@aaa.com.cn>, relay=mail.aaa.com, delay=0, dsn=5.7.1, status=bounced (host mail.aaa.com said: 554 5.7.1 <xxx@aaa.com>: Sender address rejected: Access denied (in reply to RCPT TO command))
