What is SPF, and how to Create a SPF Record?

SPF is used to prevent spammers from using an email address on your domain as their sender address, known as email spoofing.

With SPF enabled all emails you send will be tagged to notify any receiving mail servers that they should only trust emails sent from your particular mail server. If any email has your domain as the originator's address this is the only mail server they should trust as being genuine.

This is a very useful anti-spam tool and is very hard for the "spammers" to forge. Therefore it gives a better level of confidence in any anti-spam software or processes that your email is genuine.

We Recommend you use SPF in conjunction with DKIM as Authentication for your emails for even greater levels of "anti-spam" Confidence.

Note: SPF is enabled by default on all Shared Hosting Accountsbut you can change this setting within cPanel under the "Email" section and click the "Email Deliverability" Icon. Only change these records in your DNS editor within cPanel if you understand the impact of what you are changing.

How does SPF work?

With SPF you can define the outgoing mail servers that are authorized to send email from your domain name. When an email is sent from your domain, the incoming server checks if the mail comes from an approved server, before delivering it to the recipient.

If the information doesn't match, the email is identified as unauthorized and will be rejected or delivered to the spam folder.

Unfortunately, not all incoming mail servers check for SPF records. So even though adding an SPF record will help, it cannot prevent all spoofing.
