What is SPF?

SPF stands for Sender Policy Framework and is an email authentication system used to help stop unwanted email from being sent to people. SPF is a form of internet security that helps to protect your domain from being spoofed, which basically means someone is sending out emails from your domain, but the message did not originate from your actual server or accounts. This form of security is extremely important, as not having it can lead to lots of unwanted email (potentially containing malicious links or malware) being sent out under your domain and domain server.

How Does SPF Work?

SPF authentication works by using Domain Name System (DNS) records to indicate where email is allowed to be sent from and/or received from. This works to prevent unauthorized users from sending email from your domain and to limit the number of servers that will accept email from your domain. If a sender attempts to send an email from a domain that is not listed in the SPF record, then their message will be flagged as unauthenticated.

Benefits of SPF

There are a number of significant benefits to setting up SPF. The most important benefit is that it can help to control where emails from your domain can be sent from and received from, which helps to protect your server from being used to send out unwanted emails. This can be particularly important if someone somehow manages to gain access to one of your accounts, as they won’t be able to send out mass emails. In addition, SPF can also help reduce the amount of spam emails that your domain receives, as it can limit the number of servers receiving emails from you.

As you can see, there are numerous benefits to setting up SPF. Not only does it help to protect your domain from being used to send out spam emails, but it can also help to reduce the amount of spam you receive in your inbox. And best of all, setting up SPF is relatively easy and doesn’t require a lot of technical knowledge.
