Sender Policy Framework (SPF) records are part of a domain's DNS records which identify specific mail servers that are permitted to send email for a domain. The purpose of SPF records are to prevent email spam by detecting email spoofing.
To create an SPF record for your domain, you will have to log into the administrative console of your domain registrar and locate the area where you update your DNS records. You will then have to create a TXT record containing:
v=spf1 ip4:22.214.171.124/24 a mx ~all
Once you have created the TXT record be sure to save your changes. If you have any questions about configuring your SPF records, please contact us.
