By DMARCReport When you register a domain name — say mywebsite.com — you’re not done yet. To get the domain to actually load your website, or allow email to be delivered, you need to configure the Domain Name System (DNS) appropriately. Think of DNS as the internet’s “phone book.” Instead of human-readable domain names, computers…
Yes—DMARC aggregate (RUA) and forensic (RUF) reports can absolutely help you detect spoofing and phishing attempts by revealing who is sending as your domain, whether SPF/DKIM align, and where non-aligned traffic spikes point to active impersonation. DMARC sits on top of SPF and DKIM to answer a single question: did this message actually come from…
All set for Christmas? And what about your cyber preparedness? Have you braced yourself well to safeguard your data and mental peace from the cybercrooks? If not, we are here to help! Every week, we bring you a fresh dose of cyber bulletin to keep you updated and make you aware of the ongoing cyber…
Implement DMARC for multiple domains and subdomains by standardizing a DNS template (SPF, DKIM, DMARC), inventorying all sending services, using parent-level inheritance with the DMARC sp tag where appropriate, centralizing rua/ruf reporting, rolling out p=none then gradually enforcing per domain (quarantine → reject) based on report-driven confidence, automating DNS and DKIM key management via APIs/IaC,…
Introduction At DMARCReport, we’ve always believed that email authentication and brand trust should go hand in hand. That’s why the recent update from Google — enabling support for Common Mark Certificate (CMC) under Brand Indicators for Message Identification (BIMI) — is big news for businesses of all sizes. If you’re sending emails to clients, subscribers…
You can use a DMARC Analyzer—specifically DMARCReport—by publishing a DMARC record that sends RUA/RUF reports to DMARCReport, then using its dashboard, alignment checks, alerts, and policy controls to identify spoofing sources quickly and move from monitoring (p=none) to enforcement (quarantine/reject). Context and background Email domain spoofing happens when attackers send messages with your domain in…
By DMARCReport — practical, vendor-specific guidance to make your email authentication reliable and DMARC-ready. Getting SPF and DKIM right for traffic that routes through a Barracuda appliance is one of the quickest wins you can make to reduce spoofing, stop spam that appears to come from your domain, and help your DMARC policy work as…
You can create a DMARC record without breaking existing email delivery by first inventorying every legitimate sender, deploying DKIM and SPF for all of them, publishing a DMARC policy in p=none with full reporting (rua/ruf), validating alignment and fixing misconfigurations over 30–60 days, and then gradually stepping up to quarantine and reject using pct while…
