DKIM/SPF驗證

【DKIM/SPF驗證】檢測工具可以准確的檢測出的DKIM和SPF的設置是否通過Gmail，Hotmail，Yahoo的驗證。本網頁提供的微軟、谷歌及雅虎返回的DKIM檢測和SPF檢測的信息僅供參考。

請用被檢測的郵箱發送標題爲“DKIM/SPF Check Request”郵件到下面三個郵箱任何一個，過幾分鍾後刷新本網頁查看DKIM檢測結果。點擊DKIM和SPF驗證結果可以查看詳細的郵件服務器驗證信息(Authentication-Results)，Gmail、Hotmail及Yahoo對DKIM和SPF的檢測結果表述略有不同。

如果你對DKIM和SPF的驗證信息有任何疑問，請發郵件給我們，我們會及時處理。

DKIM由互聯網工程任務組（IETF）開發而成；針對的目標是互聯網最嚴重的威脅之一：電子郵件欺詐。DKIM的基本工作原理同樣是基于傳統的密鑰認證方式，他會産生兩組鑰匙，公鑰(public key)和私鑰(private key)，公鑰將會存放在DNS中，而私鑰會存放在寄信服務器中。私鑰會自動産生，並依附在郵件頭中，發送到寄信者的服務器裏。公鑰則放在DNS服務器上，供自動獲得。收信的服務器，將會收到夾帶在郵件頭中的私鑰和在DNS上自己獲取公鑰，然後進行比對，比較寄信者的域名是否合法，如果不合法，則判定爲垃圾郵件。

SPF是爲了防範垃圾郵件而提出來的一種DNS記錄類型，它是一種TXT類型的記錄，它用于登記某個域名擁有的用來外發郵件的所有IP地址。SPF的作用主要是反垃圾郵件，主要針對那些發信人僞造域名的垃圾郵件。
