What is DMARC?
DMARC, which stands for Domain-based Message Authentication, Reporting, and Conformance, is an email authentication protocol. It is a set of rules and policies that helps to prevent email spoofing and phishing attacks.
DMARC works by allowing senders to specify how receivers should handle emails that fail authentication checks. It helps to verify the authenticity of emails by combining two existing email authentication mechanisms: SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail).
With DMARC, senders can specify how receivers should handle emails that fail authentication checks. They can choose to have the email be delivered, quarantined, or rejected. DMARC also provides reporting capabilities, allowing senders to receive feedback on how their emails are being handled by receivers.
Office 365 and DMARC work together to provide a secure email communication environment. By implementing DMARC for your Office 365 email, you can ensure that only legitimate emails are delivered, while fraudulent emails are blocked or flagged.
How Does DMARC Work?
DMARC, which stands for “Domain-based Message Authentication, Reporting, and Conformance,” is a protocol used to authenticate and secure email communications. It works in conjunction with the Office 365 email platform to ensure that only legitimate email messages from authorized senders are delivered to recipients.
When an email is sent, the sender’s domain is checked against the DMARC policy published on the domain’s DNS records. The DMARC policy specifies how incoming emails should be handled, including whether they should be rejected, quarantined, or delivered to the recipient’s inbox. This helps prevent spoofing and phishing attacks.
DMARC works by using cryptographic authentication methods such as SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail). SPF allows the domain owner to specify which servers are authorized to send emails on behalf of the domain, preventing unauthorized senders from spoofing the domain. DKIM adds a digital signature to the email, allowing the recipient to verify its authenticity and integrity.
When an email is received, the recipient’s email server checks if the sender’s domain has a published DMARC policy. If it does, the server performs the necessary authentication checks using SPF and DKIM. If the checks pass, the email is delivered as usual. If the checks fail, the DMARC policy instructs the server on how to handle the email. This could include sending it to the recipient’s spam folder or rejecting it altogether.
With DMARC, domain owners have greater control over their email domain’s security. They can monitor and receive reports on email traffic, track unauthorized email senders, and take action against attempted attacks. By implementing DMARC, businesses can help protect their employees and customers from phishing scams and other email-based threats.
