An SPF (Sender Policy Framework) record is used to prevent forged email messages from spammers or other malicious sources. It is a type of DNS record that identifies which mail servers are authorized to send emails on behalf of a specific domain. When an email server receives a message, it checks the SPF record to see if the sender is authorized to send emails from that domain. If the sender is not authorized, the email server can reject the message or mark it as spam. An SPF record is an essential part of email authentication, which helps to improve the deliverability and security of email messages.
