What is DMARC?

DMARC is an email validation system designed to protect domain owners from email spoofing and phishing attempts. It works by aligning SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) mechanisms to authenticate emails and report on unauthorized or fraudulent activity using our domain.

Purpose of the DMARC Policy

Our DMARC policy aims to:

• Ensure that all legitimate emails sent from opti-surge.com are properly authenticated using industry-standard SPF and DKIM protocols.
• Prevent unauthorized third parties from using our domain to send fraudulent emails (email spoofing).
• Ensure that email messages that fail DMARC authentication are appropriately handled (either quarantined or rejected).
• Provide transparency and reporting to monitor any unauthorized use of our domain.

How DMARC Works

• SPF Authentication: SPF ensures that emails sent from our domain are coming from authorized IP addresses. It checks the sender’s IP address against the list of approved IP addresses in our SPF record.
• DKIM Authentication: DKIM adds a digital signature to emails sent from our domain to verify the message’s authenticity and integrity.
• DMARC Policy: Our DMARC policy works with SPF and DKIM to confirm that the "From" address of the email aligns with the authentication results. If the email fails authentication, it will either be quarantined or rejected based on the DMARC policy we have in place.

Reporting

Our DMARC policy also includes reporting mechanisms to provide feedback on how our domain is being used in the email ecosystem. We receive reports that help us identify unauthorized or fraudulent activity related to emails sent from opti-surge.com.

What Does This Mean for You?

If you receive an email that claims to be from Opti-Surge but does not align with our DMARC policy, it may be fraudulent. We encourage you to:

• Verify the sender’s email address before clicking on any links or downloading attachments.
• Report any suspicious emails claiming to come from opti-surge.com to support@opti-surge.com.
