DKIM/SPF验证

【DKIM/SPF验证】检测工具可以准确的检测出的DKIM和SPF的设置是否通过Gmail，Hotmail，Yahoo的验证。本网页提供的微软、谷歌及雅虎返回的DKIM检测和SPF检测的信息仅供参考。

请用被检测的邮箱发送标题为“DKIM/SPF Check Request”邮件到下面三个邮箱任何一个，过几分钟后刷新本网页查看DKIM检测结果。点击DKIM和SPF验证结果可以查看详细的邮件服务器验证信息(Authentication-Results)，Gmail、Hotmail及Yahoo对DKIM和SPF的检测结果表述略有不同。

如果你对DKIM和SPF的验证信息有任何疑问，请发邮件给我们，我们会及时处理。

DKIM由互联网工程任务组（IETF）开发而成；针对的目标是互联网最严重的威胁之一：电子邮件欺诈。DKIM的基本工作原理同样是基于传统的密钥认证方式，他会产生两组钥匙，公钥(public key)和私钥(private key)，公钥将会存放在DNS中，而私钥会存放在寄信服务器中。私钥会自动产生，并依附在邮件头中，发送到寄信者的服务器里。公钥则放在DNS服务器上，供自动获得。收信的服务器，将会收到夹带在邮件头中的私钥和在DNS上自己获取公钥，然后进行比对，比较寄信者的域名是否合法，如果不合法，则判定为垃圾邮件。

SPF是为了防范垃圾邮件而提出来的一种DNS记录类型，它是一种TXT类型的记录，它用于登记某个域名拥有的用来外发邮件的所有IP地址。SPF的作用主要是反垃圾邮件，主要针对那些发信人伪造域名的垃圾邮件。
