SparkPost预热二级域名时Gmail显示SPF验证通过但Postmaster报告SPF成功率0%的问题求助

大家好，我最近碰到一个挺矛盾的问题，想请教下社区里的朋友有没有类似经历和解决思路。

我目前用SparkPost作为ESP来预热一个二级域名，这个SparkPost的IP我们已经在主域名上用了好几个月，一直没出过任何问题。我一直在跟踪二级域名的送达情况，Gmail那边明确显示SPF验证是通过的，而且我查了相关邮件的头部信息，也能看到SPF = Pass的标记：

但奇怪的是，Postmaster那边却报告这个二级域名的SPF成功率是0%，这让我很担心会影响域名的信誉。有没有朋友遇到过这种Gmail显示SPF通过但Postmaster数据异常的情况？如果有的话，能不能分享下可能的原因和解决方案？谢谢大家！
