最近我得到了很多反弹。
我以为我的谷歌应用程序帐户已经被入侵，但我的应用程序帐户没有任何活动，当然也没有恶意用户可以看到。
由于电子邮件总是从一些随机的用户名（例如，[email protected]）发送，我试图find一种不允许从未注册的用户发送电子邮件的方式。 我找不到任何东西。
令我担心的是，这封邮件中有一个X-Google-DKIM-Signature，它说“Google试图传递您的信息”。 这是否意味着电子邮件是从我的信任客户端发出的？ （我只使用Gmail）
AFAIK垃圾邮件发送者可以自由地欺骗电子邮件的每个领域，但DKIM应该使（现代）服务器放弃这些不可validation的电子邮件。
任何想法泄漏是什么？
这是一个反弹的例子：

不要担心X-Google-DKIM-Signature（或其他一般以X-为前缀的标题），这是一个特定的Gmail，它不是一个真正的 DKIM签名为您的域名。 如果您想设置，请查看以下文章： http ： //support.google.com/a/bin/answer.py？hl = zh-CN＆answer = 174124
拒绝与DKIM无关，但与收件人有关。 但是，为什么Google邮件服务器会尝试传递错误的MX？ 对我来说没有意义。 当然，收件人系统可能configuration不正确。 失败的收件人地址是否具有相同的MX？
其他的东西：你是否validation过DKIM签名？ 也许这只是一些技术性的文字…
