Our customers complain about the problem of spam. There are a number of unidentified spam emails, which means that our SPF registration does not work. We have setup the SPF record in our DNS record and we have used SPF check tools to check the validity of our SPF record, but no issues have been reported in the audit results. I've looked at an email from our client and I've found an "X-Bordeaux-SPF: PermError" item in the email header, but no additional details are available. has been featured in the email header. I've read many resources on permerror in SPF, but I still have not found an answer that can explain the reason in this case. Now, I have no idea of the problem of our SPF registration. What could be the cause of this kind of permerror?
The domain is "made-in-china.com". The SPF record is "v = spf1 include: spf.made-in-china.com -all".
Here are the e-mail headers:
