Your DNS server is not using an SPF record. How to fix?


#1

I have recently checked my blog on SEO tool and found this Error.

Your DNS server is not using an SPF record. SPF (Sender Policy Framework) allows administrators to specify which hosts are allowed to send mail from a given domain by creating a specific SPF record or TXT record in the Domain Name System (DNS).

I don’t understand anything about this error. Please guide me
