SPF records

SPF records

An SPF record is a type of Domain Name Service (DNS) record that identifies which mail  servers are permitted to send email on behalf of your domain.SPF is an open standard  created to stop forgery of From addresses. SPF helps mail servers distinguish forgeries  from real mail by making it possible for a domain owner to say, "I only send mail from  these machines". That way, if any other machines try to send mail from that domain, the  mail server knows that the From address is forged.
