[dmarc-discuss] SPF Check issue on Google Reports

I am also seeing some problems with SPF verification by google servers

The majority of cases are "fail" spf responses, but some are "permerror"s.
Which is strange. I haven't changed my dns records in some time, and my dns
provider is Cloudflare.

Either way, this is only ~3% of the emails in the least week, for instance.
