Email authentication is more than just a best practice — it’s essential. As email threats continue to rise, weak authentication leaves your domain vulnerable to spoofing, phishing, and reputation damage. At DMARCReport, we believe every mail server owner should feel empowered to secure their infrastructure. One of the most impactful steps you can take is…
If your email domain has no DMARC record, attackers can freely spoof your domain to deliver convincing phishing and business email compromise (BEC), receiving servers won’t enforce a clear disposition for unauthenticated mail, you’ll have no visibility into abuse via DMARC reports, and your deliverability and brand reputation will degrade—especially with mailbox providers that now…
Requiring a DKIM selector improves email security and deliverability by enforcing deterministic key selection and verifiable domain-level authentication that supports safe key rotation, isolates sending streams and third parties, strengthens DMARC alignment, and increases receiver trust—leading to fewer spoofing opportunities, lower verification failure rates, and better inbox placement. Context and background DomainKeys Identified Mail (DKIM)…
Small businesses face a harsh reality: 79% have experienced at least one cyberattack in the past five years. These numbers show why companies and organizations need better protection against various security vulnerabilities. The financial toll hits hard when security breaches occur. Small businesses lose up to $1,000 per minute of downtime, while enterprise organizations lose…
In today’s digital world, we rely on websites for everything — from banking and shopping to communicating with friends and accessing critical business resources. While the internet brings immense convenience, it also presents significant risks. Cybercriminals are constantly devising new ways totrick unsuspecting users into revealing sensitive information or compromising their devices.For this reason, it’s…
Do you present prospects with multiple service options—or a single package they either accept or walk away from? Tiered pricing often sparks debate among MSPs. Some see it as unnecessary. Others worry it complicates conversations. But when you step back and look at how buyers actually make decisions, good–better–best pricing isn’t a problem at all….
The most common signs that DKIM is not working for outgoing mail are a missing or malformed DKIM-Signature header, Authentication-Results showing dkim=none/fail/permerror/temperror (often with “body hash did not verify” for bh mismatches), DMARC aggregate/forensic reports flagging DKIM alignment failures, and MTA logs indicating signing was skipped or failed due to selector/key/DNS errors. Email authentication context…
Every day, millions of people and businesses around the world fall prey to phishing attacks — fraudulent schemes designed to trick users into revealing sensitive data like passwords, financial information, or proprietary business credentials. At DMARCReport, we understand the danger these threats pose, and we want to give you a complete picture of how phishing…
You generate DMARC aggregate reports for G Suite (Google Workspace) by publishing a DMARC DNS TXT record that includes a valid rua=mailto: address for report collection, and you interpret them by parsing the XML fields (source_ip, count, policy_evaluated, dkim/spf alignment, disposition, reason) to map sending sources and authentication outcomes—best done with a purpose-built analyzer like…
In today’s digital world, email remains one of the most essential communication channels for organizations of all sizes — from multinational brands to local businesses. Yet while email offers immense marketing and operational value, it also brings challenges. One of the biggest barriers to success isn’t just sending email — it’s getting it into the…
Email continues to be one of the most widely used communication channels for businesses, consumers, and service providers worldwide. However, its widespread use has also made it a prime target for abuse. Phishing, spoofing, and impersonation attacks have increased dramatically, causing significant financial losses and eroding trust in email communication. To counter these threats, major…
To perform a DKIM lookup for your domain and verify email authentication, extract the DKIM selector from a signed message’s header, build the DNS name as selector._domainkey.yourdomain, query its TXT record with dig/nslookup (or an API), interpret the key tags, and optionally validate a message’s DKIM-Signature against that published public key. Context and background DKIM…
If you run a website based on WordPress and rely on it to send emails — user sign-up confirmations, notifications, password resets, newsletters, or contact-form replies — then you probably know how finicky email deliverability can be. Out-of-the-box WordPress typically uses the PHP mail() function, which often results in un-authenticated emails that get flagged as…
The divide between MSPs that grow year after year and those that plateau is getting wider. And it has nothing to do with: What separates growing MSPs from stagnant ones is how they operate day to day. The MSPs that scale intentionally adopt a small set of behaviours that most others either postpone, overthink, or…
Email continues to be one of the easiest ways for attackers to reach businesses. Phishing, spoofing, and brand impersonation attacks rely heavily on email because it is trusted, widely used, and difficult to police without proper controls. For service providers responsible for protecting client environments, securing email identity has become a foundational requirement. This is…
Implementing DMARC in Office 365 measurably improves inbox placement and reduces spoofing by giving Exchange Online Protection (EOP) and Outlook strong, aligned authentication signals (SPF/DKIM), but misconfiguration or unenrolled third‑party senders can lead to legitimate messages being quarantined or rejected—so phased rollout and continuous monitoring are essential. DMARC (Domain-based Message Authentication, Reporting, and Conformance) sits…
