What Is DMARC?

Domain-primarily based Message Authentication Reporting and Conformance (DMARC) is a free and open technical specification that is used to authenticate an e-mail by aligning SPF and DKIM mechanisms. By having DMARC in place, domain owners large and small can fight enterprise e mail compromise, phishing and spoofing. Co-authored by dmarcian’s founder, DMARC was first revealed in 2012.

With DMARC you can inform the world the way to deal with the unauthorized use of your e-mail domains by instituting a policy in your DMARC record. The three DMARC insurance policies are:

p=none
Monitors your electronic mail traffic. No additional actions are taken.
p=quarantine
Sends unauthorized emails to the spam folder.
p=reject
The final coverage and the ultimate goal of implementing DMARC. This coverage ensures that unauthorized electronic mail doesn’t get delivered at all.

How does DMARC work?
DMARC is based upon the results of SPF and/or DKIM, so no less than one of those has to be in place for the email domain. To deploy DMARC, it's essential to publish a DMARC document in the DNS.

A DMARC report is a text entry within the DNS record that tells the world your email domain’s coverage after checking SPF and DKIM status. DMARC authenticates if either SPF, DKIM, or each pass. This is referred to as DMARC alignment or identifier alignment. Primarily based on identifier alignment, it is possible that SPF and DKIM pass, but DMARC fails.

A DMARC report additionally tells electronic mail servers to send XML reports back to the reporting email address listed within the DMARC record. These reports provide perception on how your electronic mail is moving via the ecosystem and let you determine everything that's utilizing your e-mail domain.

Because reports are written in XML, making sense of them could be tricky, and they can be numerous. dmarcian’s platform can obtain these reports and provide visualization on how your email domains are being used, so you possibly can take action and move your DMARC coverage towards p=reject.

Why Use DMARC for E-mail?
E-mail is involved in more than 90% of all network attacks and without DMARC, it can be hard to tell if an e mail is real or fake. DMARC permits domain owners to protect their domain(s) from unauthorized use by preventing phishing, spoofing, CEO fraud, and Enterprise Electronic mail Compromise.

By always sending DMARC compliant e-mail, the operator of an Internet domain can tell the world "everything I ship is easy to determine using DMARC—be happy to drop fake email that pretends to be me."

DMARC’s utility as an anti-spoofing technology stems from a significant innovation; instead of attempting to filter out malicious e mail, why not provide operators with a way to simply establish legitimate email? DMARC’s promise is to exchange the fundamentally flawed "filter out bad" e-mail security model with a "filter in good" model.
