我有 SPF 记录：
v=spf1 include:_spf.google.com ip4:70.xx.xx.xx -all
我使用了 Google 的默认设置
v=spf1 include:_spf.google.com ~all
我已经不再使用这个默认设置，以便使用 SPF 来阻止伊朗的一些垃圾邮件发送者继续发送邮件，当他们到达虚假地址时，这些邮件会反弹给我，例如：
已接收-SPF：中性（google.com：2.191.xx.xx既不被允许也不被最佳猜测记录拒绝[[电子邮件保护]]）客户端IP=2.191.xx.xx；
该消息暗示有一种方法可以拒绝垃圾邮件发送者的 IP，但我未能找到它，所以我最终不确定。
有什么建议吗？我希望我的 SPF 直接或间接地拒绝这个垃圾邮件发送者。
更新：添加了完整、未更改的消息，我正在尝试回应（如下）

SPF 并不意味着不发送电子邮件，它只是一个标志，表示“硬失败”（-all）该消息，这会使其落入基于 ESP 的垃圾邮件文件夹中。
如果您启用DMARC使用拒绝策略，则您将 100% 导致邮件被拒绝，并且不会传递给遵守 DMARC 策略的 ESP。GMAIL 就是其中之一。
启用 DMARC 记录就像添加 SPF 记录一样简单，它完全基于 DNS 条目，就像 SPF 一样。
就您而言，您的 DMARC 记录将相当简单。
_dmarc.somedomain.ca. IN TXT "v=DMARC1; p=reject; sp=none; rf=afrf; pct=100; ri=86400"
如果您想要报告，只需将 RUA 和 RUF 信息添加到上面的记录中。您可以DMARC 生成器为您生成记录。
