sm-mta 奇怪的外发信息

今天我注意到我的邮件服务器上出现了一些奇怪的现象。我的收件箱里有一条消息，上面写着：

Received: from myserver.com (localhost)
    by myserver.com (8.14.3/8.14.3/Debian-9.2ubuntu1) id r3GJ4H5S005124;
    Tue, 16 Apr 2013 19:05:02 GMT
Date: Tue, 16 Apr 2013 19:05:02 GMT
From: Mail Delivery Subsystem <[email protected]>

这是一封似乎从我的服务器发送的邮件的退回邮件。日志显示我收到了来自此地址的垃圾邮件，但我粘贴在下面的日志的最后一行引起了我的注意。我怎么会给这个电子邮件地址发送“收件人”消息？我可以保证我从未回复过，等等。

这是在 ubuntu 上运行 sendmail。

这可以删除，或者保留答案...

原来是别名文件有拼写错误，导致某个特定用户的邮件被发送到无效地址。修复了拼写错误并运行了 newaliases，一切正常。
