我正在使用 Zoho Mail、AWS SES、GMAIL SMTP、Cloudflare 电子邮件路由和 Yahoo SMTP。它们都有自己的 SPF 记录。我在 Google 上看到了only 1 SPF should be added in hostname和maximum 10 SPF hostname is supported in 1 SPF record。
我正在尝试合并，哪一个是正确的？
v=spf1 include:_spf.mx.cloudflare.net include:zoho.in include:_spf.google.com include:_spf.mail.yahoo.com ~all
或者
v=spf1 a mx include:_spf.mx.cloudflare.net include:zoho.in include:_spf.google.com include:_spf.mail.yahoo.com ~all
或者
v=spf1 a mx include:_spf.mx.cloudflare.net include:zoho.in include:_spf.google.com include:_spf.mail.yahoo.com -all
当我使用 进行测试时遇到错误mail-tester.com。
错误 1：Maximum DNS-interactive terms limit (10) exceeded
错误 2：example.com: Sender is not authorized by default to use '[email protected]' in 'mfrom' identity, however domain is not currently prepared for false failures (mechanism '~all' matched)
