Dealing with DMARC failures: Here’s how you can fix the errors
by DuoCircle
DMARC is one of the most fundamental and robust email authentication protocols out there. It not only keeps impersonators at bay and protects your domain from being misused but also gives you visibility into who is sending emails on your behalf.
Cross-tenant migration might sound like just a technical hurdle, but it’s essentially about weaving together the digital lives of people in different organizations. Imagine being part of a company merger—suddenly, not only are you expected to collaborate with new colleagues, but your emails, files, and applications need to change homes and still work seamlessly.
Bypassing DKIM: Understanding replay attacks and how to mitigate them
by DuoCircle
Threat actors always try to stay ahead of the curve and find ways to bypass security protocols. DKIM replay attacks are exactly that. In a DKIM replay attack, a cybercriminal resends a DKIM-signed message to multiple recipients without the emails getting flagged. They generally target highly reputed domains to generate legitimate message signatures. Gmail recipients, in particular, are more likely to receive replayed emails because it greatly prioritizes domain reputation.

DMARC TempError- What is it and how can this issue be resolved?
by DuoCircle
DMARC TempErrors are the different types of authentication issues in DKIM and SPF policies. These are temporary in nature. Fixing them is important, or they may lead to DMARC failure for your legitimate emails. DMARC is one of the most significant email authentication policies, which enables domain owners to instruct recipient email servers about emails that fail SPF and DKIM checks. A TempError can easily disrupt this process, thereby hampering email authentication and deliverability.
Cloud email security refers to the measures and systems implemented to safeguard email communications against threats such as phishing, spam, and malware. It is crucial for organizations, especially those transitioning to cloud-based services like Microsoft 365, as it helps prevent data breaches and ensures the integrity of sensitive information communicated via email.
Preparing for the discontinuation of the NCSC aggregate DMARC reporting feature

Beginning March 24, 2025, the UK National Cyber Security Centre (NCSC) has stopped providing DMARC aggregate reports. Mail Check is NCSC’s official platform that helps domain owners evaluate email security compliance so that they can figure out if someone is abusing their email domains. It has discontinued the aggregating reporting feature to enhance accessibility and manage costs.
Phishing protection software is essential for safeguarding your personal and organizational data against sophisticated email threats that exploit human trust through deceptive tactics. With increasing risks of financial loss and identity theft from phishing attacks, utilizing robust security tools helps ensure real-time protection, blocking malicious links, and enhancing overall cybersecurity measures.
Most people follow ethical SEO practices, creating content that’s great for the users and easy to crawl for the search engines. The ones who want to cheat the system will try to exploit Google ranking algorithms to get a lot of traffic but risk penalty from the search engine.
How do you achieve SPF alignment to enhance email security and deliverability?
by DuoCircle
SPF alignment is one of those behind-the-scenes checks that decides whether your emails will land in the recipients’ inboxes or end up in their spam folders. Since the fate of your outgoing emails is dependent on this, you cannot simply overlook it or, even worse, assume that setting up an SPF record alone is enough.
Tenant-to-tenant migration in Office 365 involves transferring data, applications, and configurations from one Microsoft 365 tenant to another, often during mergers or organizational changes.
