SPF

As explained in AI for Everyday IT

SPF is an email-authentication standard that lets a domain specify which sending servers are authorized to send email on its behalf.

SPF (Sender Policy Framework) is an email-authentication standard that checks whether the sending server is authorized to send messages for a domain. It helps identify suspicious messages when combined with other authentication results. section 7.1.3

Checking a suspicious email

Copy an email’s source code and headers into an AI service and ask whether it shows signs of phishing. An SPF failure can support that warning, alongside DKIM and DMARC failures. section 7.1.3
