You have a company? You have a domain? You and your team send emails? If the answer to all these questions is a solid ‘yes,’ then you surely can be under the radar of email phishers and spoofers. It doesn’t matter if you have two people in your company or two thousand; you need to…
SPF records, as you may be aware, are like the bouncers of your email servers. They’re the DNS records that explicitly specify which email servers are officially allowed to send emails on behalf of your brand. By defining this list, domain owners keep out the riff-raff, preventing unauthorized people from sending emails that could tarnish…
Threat actors look for unprotected emails. They use various social engineering and phishing tactics to manipulate recipients into sharing confidential information, transferring money, downloading malware-infected files, etc. In 2023, 94% of organizations had email security issues, and considering the rise in email menaces, even Google and Yahoo explicitly state the importance of DMARC adoption. These…
All the IP addresses that you officially allow to be used for sending emails on your behalf are listed in an SPF record. When domain owners have to mention multiple IP addresses, they often use the CIDR (Classless Inter-Domain Routing) notation as it’s a way of representing IP address ranges in a compact manner. Using…
Sender Policy Framework is an email authentication protocol that allows a domain owner to publish an SPF record corresponding to their name. This SPF record includes a list of IP addresses and mail servers that the domain owner officially authorizes to be used for sending emails from. When the email reaches the recipient’s server, it…
Imagine a situation where all your well-crafted emails land in your audience’s inbox, and they actively engage with them! Sounds like every marketer’s dream, right? As much as we would want this to become a reality, it is not! Although we understand that achieving 100% email deliverability is far-fetched or rather impossible, this doesn’t mean…
As per RFC 7208, all SPF records should not be more than 255 characters long. This includes the characters in the SPF record itself as well as any DNS name expanded within it. If your SPF record exceeds this limit, there will be parsing issues and DNS lookup failures, impeding the email authentication process. So,…
SPF helps recipients’ mailboxes verify the authenticity of senders’ domains by referring to their predefined policies. To do this, the receiving server retrieves the SPF record linked to the sender’s domain. A standard SPF record consists of one or more mechanisms (like ip4, ip6, include, mx, etc.) that specify which IP addresses and domains are…
Are you also tempted to take care of the Sender Policy Framework (SPF) on your own? Do you also feel it’s an easy task and you don’t need to onboard an email authentication expert or outsource the work to a cybersecurity agency? Well, there are many business owners like you, but there are several reasons…
Hyperconnectivity is one of the key determinants of the digital world. This means that nothing exists in isolation, not even the cybersecurity attacks that impend over this space. This is particularly true for phishing and ransomware attacks. The synergy between the two cyberattacks is executed through the initial success of phishing, which allows ransomware to…
