Sendmail已经停止工作。 需要build议与错误消息

所以我的服务器已经停止发送电子邮件。 看一下/var/mail/www-data给了我一些线索。 诊断代码显示了这一点：

 Diagnostic-Code: SMTP; 553 5.1.8 Sender address <[email protected]> domain does not exist 

其余的错误如下：

我发现奇怪的是，最近在那台服务器上没有任何改变。 我唯一的想法是创build一个服务器的确切副本，所以服务器当前有一个克隆运行，这意味着有另一台服务器在那里有相同的主机文件。 这可能是造成这个问题吗？

我的主机文件目前看起来像这样：

• 在postfix中设置限制类，阻止接收和发送邮件到外部域。
• 许多无效的HELO来自
• 我怎样才能得到django注册电子邮件发送？
• Dovecot和虚拟用户问题
• 如何让Postfix从多个域发送邮件？

谁能帮忙？ 提前致谢！
