There was bad news for both Fortinet and ChatGPT Health. However, amidst this bleak landscape, experts have found a silver lining: cyberattack…
A business should use custom DKIM because it provides domain-aligned authentication that boosts deliverability and brand trust, satisfies DMARC enforcement requirements, reduces spoofing risk, and gives you operational control over keys, selectors, subdomains, and multi-ESP sending. Digital signatures are the backbone of modern email trust: DKIM (DomainKeys Identified Mail) lets receivers verify that your messages…
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…
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…
Sending bulk emails certainly means reaching a wider audience, but what if your emails fail to even reach the recipients? Such problems often occur even when you believe you are doing everything right. The reason for this error could be hidden email-policy checks running in the background that are causing your emails to fail and…

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…
Emails were never designed with security in mind, which is precisely why they require cautious use and integration with third-party tools.

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…

Cyber mishaps this week include a breach of Facebook login credentials, phishing attacks that exploit email routing gaps, fake Instagram password reset emails that sent a panic wave among the Indian user base, and a customer data breach at Betterment. Facebook login credentials accessed…
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…
