Understanding how to fix SPF (Sender Policy Framework) failure is crucial for ensuring the proper authentication and delivery of email messages. SPF is an email authentication method that helps prevent email spoofing by allowing domain owners to specify which mail servers are authorized to send emails on behalf of their domain. When SPF failure occurs, it means that the receiving mail server did not find a valid SPF record for the sending domain, or the SPF check did not pass.
