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…
Yes—forwarding can and often does disrupt DMARC alignment by breaking SPF at the forwarder and sometimes DKIM when headers or body are modified; the practical mitigations are SRS for SPF, ARC for alignment preservation, resilient DKIM practices (relaxed canonicalization and strategic re-signing), and DMARC policy/report tuning backed by continuous monitoring. Email authentication hinges on three…
It’s December, and while everyone is gearing up for the grand festivities, cybercrooks are also busy developing and executing threat campaigns. There’s something about holidays and the shopping season that these threat actors love way too much. One, people really let their guards down as they try to enjoy life. Secondly, brands try to make…
When managing a domain, one of the choices you’ll face is how to configure your DNS (Domain Name System) records. Two of the most important and commonly confused record types are A records and Alias records. Though they may seem similar, they behave differently — and choosing the right one can make a big difference…
DMARC, or Domain-based Message Authentication, Reporting, and Conformance, is one of the most crucial security protocols in your email authentication setup. As it builds on SPF and DKIM, it checks whether an email is genuinely aligned with the domain it claims to come from and, if not, how it should be handled. This sounds simple,…
