当我在 Google 上收到来自我的域(“mail.gramma.ro”)的电子邮件时,我会在标题中看到:
Received-SPF: softfail (google.com: best guess record for domain of transitioning cristi@gramma.ro does not designate 213.133.103.5 as permitted sender) client-ip=213.133.103.5;
Run Code Online (Sandbox Code Playgroud)
我的 SPF 定义为:
v=spf1 a mx ~all
你能告诉我为什么谷歌看到它有软故障状态吗?
