DMARC is an email authentication protocol that allows domain owners to specify how incoming messages from their domain should be handled and authenticated by email servers.

By implementing DMARC in Office 365, Microsoft ensures that only legitimate emails from authorized senders are delivered to Office 365 users, while potentially harmful spoofed or fraudulent emails are either quarantined or rejected by the receiving email servers.

How Does DMARC Work in Office 365?

DMARC works by combining two existing email authentication technologies, SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail).

SPF allows the domain owner to define a list of authorized email servers that are allowed to send emails on behalf of their domain. When an email is received, the receiving server checks the email headers to verify if the sending server is included in the SPF record of the domain. If the sending server is not listed as an authorized server, the email may be marked as spam or rejected.

DKIM adds an encrypted digital signature to outgoing emails from the domain. This signature is created using the domain’s private key and can be verified by the receiving email server using the domain’s public key. If the signature is valid, it indicates that the email was not tampered with during transit and was indeed sent by an authorized sender.

DMARC provides a policy framework for the domain owner to specify how SPF and DKIM should be used in combination to handle incoming emails. The policy can instruct email servers to either accept, reject, or quarantine emails that fail SPF and/or DKIM authentication. It also provides reporting mechanisms for domain owners to monitor email activity and potential sources of abuse.

DMARC authentication process in Office 365

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a security protocol that helps protect against email fraud and phishing attacks by verifying the authenticity of incoming email messages. Office 365, the cloud-based suite of productivity applications from Microsoft, does use DMARC as part of its email authentication process.

When an email is sent from an Office 365 account, the DMARC authentication process begins. First, DMARC checks the email’s sender domain to ensure it aligns with the domain used in the ‘From’ address. This alignment ensures that the sender is authorized to send emails on behalf of the domain.

If the domain alignment passes, DMARC then checks the email’s SPF (Sender Policy Framework) record. SPF verifies that the email is sent from an authorized server, preventing spammers from using fake senders. Office 365 utilizes SPF records to validate the sending server’s IP address.

After SPF validation, DMARC proceeds to check the email’s DKIM (DomainKeys Identified Mail) signature. DKIM provides a way to verify that the email hasn’t been altered during transit and that it was genuinely sent from the stated domain. In Office 365, DKIM signs the outgoing emails with cryptographic signatures that receivers can validate.

If both SPF and DKIM pass verification, DMARC evaluates the email’s alignment and authentication results. Based on the DMARC policy set by the domain owner, the email can be delivered, quarantined, or rejected. This policy helps protect the recipient from receiving fraudulent or malicious emails.

In summary, Office 365 uses the DMARC authentication process to verify the authenticity of incoming emails. By analyzing the sender’s domain alignment, SPF record, and DKIM signature, Office 365 protects its users from phishing attacks and email fraud.
