效果如下，但 cmbchina 的链接是指向 cmbchinasj.com 的，查了下，是个人的。

邮件头如下，邮件确实是从 cmbchina.com 发出，但 hotmail 标记成垃圾邮件了

Email 发件人可以任意伪造的。

发件人可以伪造啊，所以反垃圾才要求做 IP 反解析，以及才会有 DKIM 这种签名验证技术

2016-03-17 14:04:00 +08:00 via iPad

这封邮件是伪造发件人的， Outlook 通过 SPF / PTR / DKIM 等手段把它识别出来了，所以它是被丢进垃圾箱的。

发邮件的时候，协议里可以随便填发件人的信息的，只是现在的邮件运营商会帮你填你的信息罢了，自己建个服务器就呵呵了

首先， message.cmbchina.com 这个域名并不存在！
其次， 115.210.202.182 的 PTR 记录也不是指向 message.cmbchina.com

正是未通过域名反解，所以， Hotmail 才将这个邮件定义为垃圾。

发件人应该是宁波电信的宽带用户，直连上 hotmail 的 smtp ，伪造发件地址来发信的。

2016-03-17 17:46:33 +08:00

1. 发件地址可以伪造
2. 锚文本跟链接具体指向没什么关系吧（之前还在乌云看到过鼠标放在锚文本上，浏览器左下角显示的链接也是可以伪造的——跟具体点进去的网页不一样）
3. 正文中“银行”二字为了防止简单的 spam filter 居然加了空格，这种邮件还用想吗，说他是垃圾邮件都是褒奖他， low 爆了

[邮件确实是从 cmbchina.com 发出] 根本就不是……所以不要直接无脑猜啊。
