我收到了一封来自[电子邮件保护]声称我已经获得了助理经理的面试机会(确切的说法是 -您申请助理经理职位的结果已公布。我想邀请您参加面试。)并附带一份 PDF 文件。
我知道这是假的,因为它要求我在面试前交钱。
邮件标题如下。如何从标题中判断邮件的真正来源以及是否是垃圾邮件?

我知道这是垃圾邮件,但我想了解邮件头的哪一部分表示这是垃圾邮件。
答案1
如何从电子邮件的标题判断发件人地址是否合法?
许多此类电子邮件标头都可以(并且通常会)被垃圾邮件发送者在发送垃圾邮件时伪造。
- “发件人:”地址
- 一些“已收到:”标头也可以伪造。
SMTP 邮件欺骗显示了使用开放(不安全)中继邮件服务器可以多么轻松地完成此操作。
我如何分析电子邮件标题?
有许多工具可以分析电子邮件头,其中一些可以显示链中的任何 IP 地址是否在垃圾邮件黑名单上。
这些工具还可以判断链中的任何“已接收:”标头是否是伪造的。
MxToolbox 电子邮件标头分析器
其中一个工具是MxToolbox 电子邮件标头分析器
将您的电子邮件标题输入此工具将产生以下输出:
单击黑名单按钮会显示 IP 地址 182.50.144.34(谷歌从该地址收到电子邮件,并且该地址在 3 个电子邮件黑名单中)。
