foxmail 如何鉴别一封邮件的发件地址是否是伪造的？

[MarioLuisGarcia]

工作中会经常收到伪造的邮箱发过来的信件，发件地址可以伪造成任何地址。
请问有没有方法鉴别这些伪造地址？

只有互相pgp密码发送内容才可信

@loading 若我给某人发了一封信，他的回信里带着我原信的内容，基本就说明这个回信是从真实地址回过来的吧？

如果是你的信也被拦截呢？呵呵

PGP 签名

在信件未被拦截的情下，这种判断方法是可行的？ 另，谢谢关于pgp密码的信息。

There are several approaches to dealing with email forgery:

Use PGP or SSL signed certificates
Use SPF
check the Received headers (although this isn't reliable)
reply back to the sender and ask if they actually sent it. If you know the sender, maybe ask them in person or over the phone.

SPF
DMARC

@loading PGP竟然被Symamtec收购了，好伤心

查看邮件头应该是比较简单方便的
