SPF, which means Sender Policy Framework, is an email security system, which is employed to verify whether an email message was sent by a certified server. Using SPF protection for a particular domain name will stop the faking of emails created with the domain. In simple words: enabling this attribute for a domain generates a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers which are allowed to send e-mail messages from mailboxes using the domain. Once this record propagates globally, it exists on all of the DNS servers that direct the Internet traffic. Whenever a new e-mail message is sent, the first DNS server it goes through verifies whether it originates from an authorized server. When it does, it's sent to the destination address, however if it does not originate from a server indexed in the SPF record for the domain, it is rejected. In this way nobody will be able to mask an e-mail address to make it appear as if you're distributing spam messages. This technique is also termed email spoofing.
