Description

SPF, DKIM, and DMARC are essential protocols for securing email communications and preventing domain spoofing. Sender Policy Framework (SPF) ensures that only authorized servers can send emails on behalf of a domain, while DomainKeys Identified Mail (DKIM) uses cryptographic signatures to verify email authenticity. DMARC ties these two protocols together, instructing receiving servers on how to handle unauthorized messages.

Implementing these email security measures protects organizations from phishing attacks, spam, and other email-based threats. It also enhances email deliverability and ensures brand reputation by preventing attackers from impersonating the organization. Together, SPF, DKIM, and DMARC form a comprehensive shield against email fraud, securing one of the most critical communication channels for businesses.
