What is DMARC quarantine? Understanding the p=quarantine policy in 2026
by DuoCircle
Email authentication has moved far beyond a technical checkbox. In 2026, mailbox providers expect domains to actively enforce authentication policies to prevent spoofing and phishing. This is where DMARC policies become critical, especially the p=quarantine setting.
What mail relay servers are, why they’re targeted, and the risks of misconfiguration
A mail relay server is the SMTP-facing component that accepts, routes, and forwards messages under the simple mail transfer protocol. In practice, an smtp server acting as a relay server moves electronic letters (digital mail) from senders to the recipient’s smtp server, often using a smart host to aggregate and optimize outgoing email.
Most scraping failures are predictable once you measure the right things. Marketing and business teams want reliable acquisition from product pages, search results, and reviews, yet too many pipelines rely on trial and error. A practical strategy uses verifiable signals about browsers, networks, and page behavior so you can tune scrapers with confidence, not guesswork.
Improperly authenticated emails can leave your domain susceptible to issues such as spoofing, phishing, and undelivered messages, often without your awareness. Conducting a Domain-based Message Authentication, Reporting, and Conformance (DMARC) assessment is essential to uncover security vulnerabilities that malicious actors may take advantage of, and it helps ensure that your email system is adequately secured.
Email remains an essential communication channel for businesses worldwide, playing a critical role in marketing, customer engagement, and internal collaboration. Despite the rise of instant messaging and social media platforms, email continues to be the backbone of professional communication, handling over 300 billion messages daily as of 2023. However, the mechanics behind reliable email delivery are complex and involve multiple operational layers. Ensuring that an email arrives promptly, intact, and securely requires a deep understanding of protocols, infrastructure, and cybersecurity measures.
Your website is the place prospects decide whether you feel credible, customers decide whether you feel current, and partners decide whether you feel easy to work with. If publishing a new page still requires a ticket, a developer handoff, and a quiet prayer that nothing breaks, your CMS is charging you interest every week.
Email security threats continue to evolve, making strong authentication more important than ever. One of the most effective ways to protect your domain from spoofing and phishing attacks is by implementing DomainKeys Identified Mail (DKIM). By adding a DKIM record in your DNS, you create a digital signature that verifies your outgoing emails are genuinely sent from your domain and have not been altered in transit.
Here are the top 4 recent cyber incidents that kept the security experts on their toes. The renowned medical equipment manufacturer UFP Technologies was targeted by threat actors. On Wednesday, Olympique de Marseille experienced a cyber mishap, after which the authorities decided to reissue e-tickets. Meanwhile, there has been a sudden spike in phishing attacks on UK organizations. Also, a group of cybercrooks is using @google.com to run a new phishing campaign.
Deploying DMARC the right way: Here’s what MSPs and enterprises should know
by DuoCircle
On the surface, DMARC deployment is simple. In theory, all it requires you to do is publish a DNS record and enable monitoring—that’s all. But in reality, this approach does not really work for MSPs and enterprises. The entire purpose of implementing DMARC is negated if the authentication protocol is stuck at “p=none” for your email-sending domain.
