What is DMARC?
DMARC, or Domain-based Message Authentication, Reporting, and Conformance, is an email authentication protocol that is used to protect email domains from unauthorized use, such as phishing and email spoofing. DMARC uses technologies like Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to authenticate email messages. It is important to understand the concept of authentication, as without it, cybercriminals can easily impersonate actual brands, making it difficult for people to distinguish between valid and fraudulent emails.

What is SPF?
Sender Policy Framework or SPF is a mechanism that notifies mail exchanges about which mail servers are authorized to send emails using the domain name. SPF protects email users from receiving spam, phishing messages, and fraudulently forged emails. SPF records are published in DNS (Domain Name Service) directories, and they work by ensuring that all emails that come from a particular domain are coming from authorized mail servers. Essentially, it is a way of verifying identities before allowing messages to be sent.
What is DKIM?
DomainKeys Identified Mail or DKIM is an email authentication protocol that verifies that an email message was sent from an authorized mail server using an encrypted digital signature. DKIM protects businesses against impersonation attacks, such as phishing and email spoofing. DKIM works by adding a digital signature to the email header, which provides an additional level of authentication when the mail is received.
How does SPF and DKIM work with DMARC?
DMARC is a combination of SPF and DKIM, which form a necessary integration to provide a high level of email security. SPF helps to verify that incoming email messages are sent from authorized mail servers, while DKIM helps to verify that the message has not been modified or tampered with in any way. When DMARC is used, it takes these technologies one step further by ensuring that the domain owners themselves can be notified when someone attempts to use their domain name for malicious purposes.
