每次我向 Gmail 帐户发送电子邮件时，Outlook 都会收到以下错误消息。只有 Gmail 帐户受到影响。我使用 Microsoft Exchange Server 的网络解决方案。我可以接收来自 Gmail 的电子邮件。

我使用 Cloudflare 为我的网站 natampa.com 提供安全保障。Network Solutions 建议我添加以下 SPF 记录：
v=spf1 include:spf.cloudus.oxcs.net ~all
我已经将其添加到我的 Cloudflare 帐户，但没有效果。
不幸的是，Network Solutions 根本帮不上忙。我一直在研究应该在 SPF 记录中填入什么，现在我得到了以下内容：
v=spf1 include:spf.protection.outlook.com ~all
但仍然不起作用。我只有一个 SPF 记录。我尝试过以下方法：
v=spf1 include:_spf.google.com include:servers.mcsv.net ~all
而且它也不起作用。
任何指导都将不胜感激。
答案1
经过一番努力，我终于找到了 Network Solutions 的技术人员来帮助我。该记录的正确语法是：
v=spf1 include:spf.serverdata.net -all
