CC e-mail的意思|示意

Invocation of such a command line launches the user's E-mail client, populates its elements (cc: list, attachments, and so on), and turns over control to the end user.

调用这样的命令行会启动用户的电子邮件客户机，填充它的元素(例如列表、附件等)，并把控制权转移给最终用户。

The problem was that an E-mail message with a carefully-crafted "from," "to," or "cc" field could give the sender complete (root) control over any machine running Sendmail as it's commonly configured.

问题在于，按通常的配置，精心设置了“from”、“to”或者“cc”域的电子邮件消息可以让发送者完全(root)控制任何一台运行着Sendmail的机器。
