You may already know that SPF records are TXT-type DNS records that domain owners create to mention SPF policies and enlist the mail servers they authorize to be used to send emails on their behalf. TXT records help store text-based information associated with a domain, which is then published on the DNS for public retrieval….
Once you are done with creating SPF and DMARC records to safeguard your email communications, the next step requires you to publish the records onto your domain’s DNS. Updating them on DNS ensures that the recipient mailboxes are able to retrieve them and run email authentication checks, thereby preventing any kind of malicious attempts. Based…
In SPF, a DNS lookup is the process using which the receiving mail server fetches the SPF TXT record of the sender’s domain. This is done to verify if the sender is authorized to send messages on behalf of the domain owner. However, to prevent abuse and overburdening, RFC has imposed a limit of a…
SPF prevents emails sent by unauthorized people from landing in the inboxes of targeted recipients. However, if your SPF record is misconfigured, it can do more harm than good- especially if it’s overly permissive. By overly permissive, we mean using the +all mechanism, as this setting can turn your domain into an open relay for…
We know that email is one of the most crucial aspects of your business communication, but we hate to break it to you; it’s also the most vulnerable one. Why do we say that, you ask? Cybercriminals see emails as the easiest entry points and then intercept them, add something fishy or alter their content,…
Back in the days when SMTP (Simple Mail Transfer Protocol) was designed, it lacked any authentication techniques. Over time, threat actors started misusing email communication channels as they were only protected by passwords, which are easy to breach. As emails became one of the common attack vectors, companies felt the need to devise a solution…
Has it ever happened to you that you sent an email, but it never reached the recipient despite doing everything right? You authenticated your email-sending domain with SPF, DKIM, and DMARC, but somehow, your emails aren’t getting through. Well, one of the reasons behind this could be that your authentication protocols aren’t correctly configured, particularly…
Email security has seen many developments over the years. Starting in February 2024, Google and Yahoo made it mandatory for bulk senders to implement SPF, DKIM, and DMARC to combat the growing menaces attempted through phishing and spoofing. Now, Yahoo Japan has also taken a step further in the same direction— it has made it…
DORA (Digital Operational Resilience Act) is a Europe-based framework explicitly designed to establish regulatory compliance for the finance sector. This act has been in force since January 2025. Though DORA and DMARC are not directly linked with each other, DMARC helps in DORA compliance by improving the email security posture. DMARC is an email authentication…
You would be surprised to know that as many as 3.4 billion emails are sent by threat actors every single day around the globe to gain illegitimate access to sensitive user data. That’s precisely why email authentication plays a significant role in safeguarding your business email communications by securing your domain from phishing and spoofing…
