gmail 的 mx 條目和 gmail 的 spf 程式碼在 cpanel 上就位，但是每次我嘗試從我的Google應用程序帳戶發送電子郵件時，它都會被視為 Outlook 欺詐，並且 spf=softfail（如果這意味著什麼）+ X- AUTH-結果：失敗 X-SID-結果：失敗。不知道該怎麼做，誰能幫我解釋為什麼這樣做或如何解決它？

將不勝感激:)

如果您從Google伺服器發送，請包括Google伺服器：

v=spf1 mx ip4:184.171.248.66 include:_spf.google.com ~all

您還可以測試以確保這與http://testexchangeconnectivity.com一起使用並選擇“出站 SMTP 測試”

+a 和 ip4:184.171.248.66 是多餘的，總是首選 IP 地址來保存 DNS 查找限制為 10。
