SPF Compression and Its Role in Email SPF compression is more than just a technical buzzword; it’s an essential practice that enhances the functionality of your email authentication strategies. The Sender Policy Framework (SPF) specifies which servers are permitted to send emails on behalf of a domain, using a simple text record that contains relevant…
The New Zealand government recently published its Secure Government Email (SGE) framework. It’s designed to protect official information from email-based menaces, primarily phishing and spoofing. All the New Zealand government agencies must comply with the requirements by October 2025. These standards are introduced to improve email security while also retiring the outdated SEEMail service. This…
Can You Have Multiple SPF Records? The crux of the matter is that you cannot have multiple SPF records for a single domain. This is not merely a suggestion; it’s rooted in the technical specifications outlined in RFC 7208, which state unequivocally that only one SPF record should exist per domain. Straying from this guideline…
An SPF record is the primary authorization layer that determines whether your SPF configuration will be effective or let any domain send emails on your behalf. These records are basically a list of all the addresses and domains that are allowed to send emails using your domain name. These are published as DNS TXT records…
Looking into an SPF record and figuring out what these alien terms are: a, mx, ip4, and include? Guess what, you are not alone. Anyone with no-so-adept technical expertise feels the same at first glance. SPF is undoubtedly one of the powerful tools for combating phishing and spoofing attempts made in your name. However, creating…
When you think about emailing, it’s easy to overlook the behind-the-scenes work that keeps those messages flowing smoothly. Yet, just like a well-tuned machine, email systems rely on specific rules to prevent chaos, especially with pesky threats like spam and phishing attacks. One of these essential rules is the Sender Policy Framework (SPF), which helps…
In a time where our inboxes overflow with messages, not all of them are as innocent as they seem. Many people routinely fall victim to phishing scams and email spoofing, which can lead to frustrating experiences or even financial loss. So, how do you protect yourself against these threats? Enter Mimecast SPF, a crucial tool…
DMARC is no longer just a best practice; it is now a requirement. Now, regulatory bodies across the world mandate the implementation of SPF, DKIM, and DMARC for safeguarding user and employee details. If you send bulk emails or work in finance, healthcare, government, or SaaS, you need DMARC, or else you will be subjected…
SPF is a sensitive email authentication protocol; it requires all details to be correct to produce accurate authentication results. You can’t miss adding new IP addresses and mail servers, or you can’t afford a tiny typo; otherwise, even genuine emails can get marked as spam or rejected. It’s important to regularly run your SPF record…
As per a report, more than 90% of the world’s top 1.8 million email domains are still at risk of spoofing attacks because only 7.7% of them have set up the strongest DMARC policy, called p=reject, which fully blocks unauthorized emails. While Google, Yahoo, and Microsoft are encouraging users to implement DMARC, the configurations in…
