What is the difference between DKIM and SPF?
DKIM (DomainKeys Identified Mail) and SPF (Sender Policy Framework) are both email authentication methods. DKIM uses cryptographic signatures to verify that an email was sent by an authorized server, while SPF checks if the sending server's IP address is authorized to send emails on behalf of the domain.
How do they work together?
They complement each other. SPF verifies the sender's IP, while DKIM ensures the email content hasn't been altered. Using both increases email security.
Which one is more important for email security?
Both are important, but DKIM is often considered more robust because it protects the integrity of the email content, while SPF mainly focuses on sender verification.
Can I use one without the other?
Yes, you can use one without the other, but it's recommended to implement both for better protection against spoofing and phishing.
