SPF, which means Sender Policy Framework, is an email security system, which is employed to confirm if an email message was sent by an authorized server. Employing SPF protection for a particular domain will prevent the faking of email addresses created with the domain. In simple words: activating this function for a domain creates a specific record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send e-mails from mailboxes using the domain. As soon as this record propagates globally, it exists on all DNS servers that direct the Internet traffic. Whenever an e-mail message is sent, the initial DNS server it uses verifies whether it comes from an authorized server. When it does, it is forwarded to the destination address, but when it doesn't come from a server indexed in the SPF record for the particular domain, it's discarded. In this way nobody can mask an email address then make it appear as if you are distributing spam. This technique is also known as email spoofing.
