“Noncompliance isn’t just risky—it can mean lost licenses, lost trust, and lost business,” says Joe Garner of dmarcian. At the MSP Summit in Orlando, Doug Green, Publisher of Technology Reseller News, caught up with Garner and colleague Billy Muldoon to discuss why DMARC—the standard for authenticating email—should be a top priority for MSPs and their clients. Founded by Tim Draegen, the primary author of DMARC, dmarcian’s mission is to spread adoption of the open standard across the email ecosystem. DMARC builds on earlier protocols (SPF and DKIM) by providing visibility, daily reports, and strong policy enforcement—giving organizations the ability to stop phishing and spoofing attacks at the domain level. For MSPs, the opportunity is clear: DMARC not only protects customer brands but also creates billable project work and recurring revenue streams. By moving client domains from “none” to “reject” policies, MSPs can deliver compliance, reduce support tickets, and demonstrate measurable value. Muldoon emphasized that while AI dominates industry headlines, DNS and email remain critical points of vulnerability. “Email is still the biggest attack vector,” he said. “MSPs can’t overlook DMARC—it’s both a defensive necessity and a revenue opportunity.” With Google, Yahoo, and now Microsoft requiring DMARC alignment for bulk senders, enterprises must act or risk delivery failures. dmarcian provides MSPs with the tools to visualize mail streams, track compliance, and guide customers through the journey to strong DMARC policies.
