我在邮件服务器上发现了一些奇怪的东西。 我在收件箱里留言说：
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]> 这似乎是从我的服务器发送的消息反弹。 日志显示我从这个地址收到垃圾邮件，但是接下来粘贴的日志的最后一行引起了我的注意。 我怎么会有这个电子邮件地址的“TO”信息？ 我可以保证我从来没有回复过
这是在Ubuntu上运行的sendmail。

这可以被删除，或留下答案…
事实certificate，别名文件有一个错字，以便一个特定用户的邮件被发送到一个无效的地址。 修正了错字并运行了新语言，一切都很好。
