Sender Policy Framework (“SPF”) records allow you to determine which computers can send email on behalf of your domain.
Adding a SPF record to your domain name's TXT entry, can help improve email delivery rates by reducing the chance that the emails you send will be seen as spam. It can also help prevent others from sending spam and using your domain name.
