email - 电子邮件标题中的敏感信息？

Question

如果收件人：电子邮件被删除，电子邮件标题中是否有任何敏感信息？

我问的原因是因为我正在启动一个项目（像许多其他项目一样）来记录收到的垃圾邮件。我计划发布标题（删除我的电子邮件和姓名）。

所以我想知道是否有垃圾邮件发送者（或其他任何人）可以根据标题内容检索私人信息

想法？

好吧，这就是路由路径——Received标头显示了哪些服务器中继了它，以及它们的 IP 地址。如果您担心在那里暴露 DNS 名称和 IP 地址，您可能需要删除它们。还有Message-ID，它在源服务器上应该是唯一的，但在这种情况下并不真正相关：

So, the most relevant part would be the routing data - unless you use a hosted service where you can hide in the crowd (e.g. gMail), this could be used to guess the domain of the recipient.
