qq 邮件信头疑问, Received 后面的时间 与 Date:后面的时间 分别是指的什么时间?

    比如:
    ......
    Received: from [192.168.0.1] (unknown [xx.xxx.xx.xx])
    by esmtp4.qq.com (ESMTP) with SMTP id 0
    for <[email protected]>; Mon, 16 Nov 2015 11:52:31 +0800 (CST)
    ......
    Date: Mon, 16 Nov 2015 11:52:30 +0800
    ......

    received: 后面时间是收件时间嘛?
    Date: 是发件时间嘛?

    由于date的时间 先于 received时间, 那么这个头文件至少部分是倒着写的? 从下往上写?

    请问哪里有qq邮件header的详细解释?

    Date 是发信端的邮件客户端生成的
    Received 是邮件转递过程中的服务器另外加进去的。一般加在更头部的位置
    另外最末一步 有可能会加个 Delivered-To
