SPF or Sender Policy Framework is the first line of defense between your email ecosystem and email-based cyberattacks. It ensures that only authorized mail servers can send emails on behalf of your brand and from your domain, which helps to protect your organization from phishing and spamming. But what if this line of defense is…
SPF delegation is a one-time setup where a domain owner gives control of their SPF record to an external email server or a third-party service to send emails on behalf of the domain. To do this, you have to make some changes to the current SPF, and the revised record has to be published by…
It was not long ago when Google and Yahoo revamped their email-sending policies and made DMARC authentication a mandatory exercise for organizations sending more than 5,000 emails a day. The aim of these mail service providers was simple— to build a cyber-resilient digital ecosystem. Recently, another major ESP— Microsoft, jumped the bandwagon and announced that it…
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…
Understanding the realities and limitations of the Sender Policy Framework (SPF) is crucial for making informed decisions about your email security.

Email security was a headache for tech giants (and even some smaller companies) in the late 1990s. It was the time when threat actors started exploiting email communications to attempt impersonation, spoofing, and phishing-based attacks in the names of reputed companies and domain owners. Considering the rise in email-based cyber menaces, many experts got involved…
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.
