SPF Record
A DNS record that authorizes specific servers to send email for a domain — prevents spoofing.
A Sender Policy Framework (SPF) record is a TXT DNS record that specifies which mail servers are authorized to send email on behalf of a domain. SPF helps prevent email spoofing and phishing by allowing receiving servers to verify the sender's legitimacy. An SPF record might look like: "v=spf1 include:_spf.google.com ~all." Domains without SPF records may have email marked as spam.
