主域收发正常，次域收发都不行！急！急！急！

hook

我的邮箱服务器建有一个主域和几个次域，前几天发现次域的用户不能发信，给次域用户发的信也被退回。但主域的用户一切正常。A及MX记录均正确，请高手帮忙解决，非常感谢！

发信的错误如下： 发送邮件时发生错误！550<[email]aaa@163.com[/email]>,Recipient unknown

退信内容如下：
抱歉，您的邮件被退回来了……

原邮件信息：	时　间： 2011-04-16 15:16:37 主　题： 收件人： abc@xxx.com 抄　送： xxx 密　送： yyy
退信原因：	接收者的地址不存在，不是一个有效的地址，故无法发送成功。 英文说明:SMTP error, RCPT TO: 550 , Recipient unknown.(SMTP error, RCPT TO: 550 <abc@xxx.com>, Recipient unknown)
建议解决方案：	请您先核实对方邮件地址是否正确，比如：检查用户名或域名的输入是否正确，如果是直接复制对方地址，请核实是否复制了其他的符号，如空格等。正确的邮件地址格式例如：XXXXX@163.com。核实无误后请再次发送或通过其它方式和对方先联系。

日志如下：

從上面日誌看來發信沒有問題，只是收信地址不對，也就是說收信人地址不明。

发邮件时提示：发送邮件时发生错误！这个一般就是DNS设置的问题，建议查一下。
可能回复的晚了一点了。。。
