What is the difference between DMARC, SPF, and DKIM?
DMARC, SPF, and DKIM are email authentication methods. SPF verifies sender IP addresses, DKIM adds a digital signature, and DMARC combines both to protect against spoofing.
How do these methods work together to improve email security?
They work in tandem: SPF checks if the sender's IP is authorized, DKIM ensures the email content hasn't been altered, and DMARC enforces policies based on SPF and DKIM results.
Can you explain how to set up DMARC for my domain?
To set up DMARC, you need to create a DMARC record in your DNS settings. This record specifies your policy for handling emails that fail SPF or DKIM checks.
What happens if I don't implement these protocols?
Without these protocols, your domain is more vulnerable to phishing and spoofing attacks, which can damage your reputation and lead to loss of trust.
