When a Domain-Message Authentication, Reporting, and Conformance) check fails, it indicates that an email message has not the authentication process set up by the receiving domain. DMARC is an email authentication protocol that helps prevent email spoofing, phishing attacks, and domain impersonation by allowing domain owners to specify how messages from their domain should be if they fail authentication checks.
A check typically occurs
when the email message’s alignment with the domain’s policies does not meet the requirements. alignment involves two indonesia phone number key components: SPF (Sender Policy Framework and Identified Mail). SPF verifies that the sender’s IP address is authorized to send emails on behalf of the domain, while DKIM validates the cryptographic signature of the email message to ensure it has not been in transit.
When an email fails the
check the receiving domain can choose to take various actions on the DMARC policy set by the sender. These actions may include quarantining the Belgium Phone Number List message it to a spam or quarantine folder. Rejecting the message outright, or allowing the message to be while marking it as suspicious.
There are several reasons why a check may fail, including SPF or DKIM recordssenders trying to impersonate the domain, or issues with the email infrastructure or authentication setup. It is essential for domain owners to regularly monitor their reports to identify checks analyze the root causes and take corrective actions to improve email deliverability and security.
To address check failures, domain owners can review and update their and records to ensure they accurately reflect their senders and email practices. It is also crucial to configure the policy effectively, setting appropriate alignment requirements and specifying how to handle messages that do not meet authentication standards.
Additionally, domain owners can leverage reporting tools to gain insights into email authentication failures, monitor compliance rates, and identify potential threats or vulnerabilities. By analyzing reports and implementing best practices, organizations can enhance their email security posture, protect their brand reputation, and the risk of email-attacks.
