如何檢查，測試和確認SPF紀錄在DNS是正確和合法的

SPF紀錄在領域DNS樹水平是與設法偽造或欺騙發令者SMTP郵寄和返回道路從您的領域區域的電子郵件發送同樣的消息到多個新聞組交戰的新工具。 然而， SPF定義的不正確或錯配置可以導致電子郵件過早地被放棄，彈起和沒交付到預期的接收人。 因而它是很好的練習測試，核實和確認保證SPF政策不錯誤地造成向外去電子郵件出故障和unaccepted由中轉郵件服務器。

我的數字式生活提供 SPF檢驗-發令者測試和檢查工具的外形框架一個簡單的驗查員和測試者為領域SPF紀錄使用DNSStuff服務。 簡單地進入想要測試的SPF串，或者輸入領域或電子郵件為在SPF價值的自動發現上，并且郵件服務器的IP地址，工具將退回SPF檢驗結果為起源於那臺服務器的電子郵件它是否將接受。

Python基於SPF紀錄測試工具 有幾個測試。 管理員裝於罐中檢索SPF紀錄為指定的域名，確定SPF紀錄是否是合法的，檢查SPF紀錄是否是語法上對SPF的正確和合法(有用，在DNS出版SPF)之前和充分的測試通過評估根據郵件也許來自的不同的IP地址的SPF紀錄表現。

Vamsoft有 SPF驗查員 哪些將執行同一試飛以公共事業我的數字式生活提供得上述，和 SPF句法Validator 核實SPF串的句法是正確的。

Return Path also provides a SenderID Test similar to above email verification service, except that the it uses one time random email address that you suppose to send to, auto-generated when you visit the website, and validator won’t automatically reply to your email with validation report. Instead, webmasters will need to enter their email address on the box provided on the same web page to get the results.
