Final answer:
SPF records and DKIM records are commonly used to stop email spoofing and spam. Another commonly used record is the DMARC record.
Step-by-step explanation:
SPF records and DKIM records are commonly used to stop email spoofing and spam. SPF records (Sender Policy Framework) specify which servers are authorized to send emails on behalf of a domain, helping to prevent spoofing and ensure the emails are legitimate. DKIM records (DomainKeys Identified Mail) add a digital signature to emails, allowing the receiving server to verify the authenticity of the message and detect any tampering.
Another commonly used record is the DMARC record (Domain-based Message Authentication, Reporting, and Conformance). DMARC combines SPF and DKIM, and it provides instructions on how to handle emails that fail authentication checks, such as marking them as spam or rejecting them.
