Sender Policy Framework, or SPF, is a verification system, that is employed to stop the so-called email spoofing where an email message can be sent from one email address, but to look as being sent from another, generally with the purpose to fraud the recipient for some reason. When SPF protection is enabled for a domain name, an exclusive record is made for it in the Domain Name System and all of the DNS servers worldwide get it. The record features all of the mail servers that are permitted to send legitimate messages from an address within the domain. When an e-mail is sent, the first DNS server it encounters checks the SPF record and if the sending server is authorized, the message is forwarded to the target destination. If, however, the sending server doesn't exist in the SPF record for the particular domain, the e-mail message will not be forwarded and it will be removed. Whenever you use this service, it'll prevent third parties from sending spam emails that seem to have been sent by you.
