PostFix 550 5.1.1从外部电子邮件找不到收件人

这是一个新的安装。 当用户存在时，PostFix报告“550 5.1.1”“收件人找不到”。

• 用户可以发送电子邮件到处。
• 用户可以通过本地主机相互发送邮件。
• 所有外部电子邮件给用户返回550 5.1.1错误消息。

我没有看到maillog文件中的任何错误。 我想我已经阅读了这个网站的每一个线程，其中“550”，但不是答案似乎是适当的。 有谁知道为什么知道的用户被报告为没有find？

这是我的configuration文件：

/etc/postfix/master.cf

• 启动时间日志：“无法启动Postfix邮件传输代理”
• postfix不会将邮件路由到远程主机
• Postfix在两个不同的DB上查找virtual_mailbox_maps mysql
• Logwatch后缀报告。 这个“延期”从哪里来，如何制止呢？
• Postfix忽略relay_recipient_maps？
