您的 SPF 策略表示允許誰代表您的網域發送電子郵件。它目前看起來像：
tatoocdc.com. 14400 IN TXT "v=spf1 +a +mx +a:tatoocdc.com -all"
嘗試傳送電子郵件（IP 位址為 83.235.69.32）的伺服器無論如何都不包含在該清單中。因此gmail拒絕接受該郵件。您的 SPF 記錄的具體設定方式。
如果應允許主機名為 的 83.235.69.32smtp-out32.otenet.gr.為您的網域傳送電子郵件，則應修改 SPF 記錄以包含該主機。
設定例如"v=spf1 +a +mx +a:tatoocdc.com +ip4:83.235.69.32 -all"
