How can I create a DMARC record for my domain to stop email spoofing?

How can I create a DMARC record for my domain to stop email spoofing?

ByBrad Slavin

To stop email spoofing, create and publish a TXT record at _dmarc.yourdomain.com with a value like v=DMARC1; p=reject; rua=mailto:dmarc-reports@yourdomain.com; ruf=mailto:dmarc-forensics@yourdomain.com; adkim=s; aspf=s; pct=100; fo=1; ri=86400 only after verifying that all your senders pass SPF and/or DKIM in alignment with your From domain. DMARC (Domain-based Message Authentication, Reporting, and Conformance) lets domain owners tell receivers how…

CNAME vs ALIAS Records — A Guide by DMARCReport

ByBrad Slavin

As DNS users, domain administrators, and website operators know all too well: DNS configuration often feels like walking a tightrope. A small misconfiguration can mean your users can’t reach your site — or your email goes missing. Two DNS record types that are often sources of confusion are CNAME and ALIAS records. They can look…

Boost Deliverability with Gmail DMARC: What Every Sender Must Know

ByBrad Slavin

To boost Gmail deliverability with DMARC, you must implement aligned SPF/DKIM/DMARC on your Google Workspace domain, stage policy from p=none to quarantine to reject while monitoring Gmail-specific signals, authorize third-party senders with aligned keys and SPF, handle forwarding with ARC, optimize SPF under lookup limits, enable BIMI, and continuously analyze RUA data with DMARCReport for…

CNAME vs A Record: What Every Domain Owner Should Know

ByBrad Slavin

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…

Can DMARC Reports Help Me Detect Spoofing And Phishing Attempts?

Can DMARC Reports Help Me Detect Spoofing And Phishing Attempts?

ByBrad Slavin

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…

How can I implement DMARC for multiple domains and subdomains?

How can I implement DMARC for multiple domains and subdomains?

ByBrad Slavin

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,…

How can I use DMARC Analyzer to detect if my domain is being spoofed?

How can I use DMARC Analyzer to detect if my domain is being spoofed?

ByBrad Slavin

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…
