SPF, which is short for Sender Policy Framework, is an e-mail security system, which is is intended to verify if an e-mail message is sent by an official server. Using SPF protection for a domain name will prevent the forging of email addresses generated with the domain. In simple words: activating this attribute for a domain makes a particular record in the Domain Name System (DNS) which contains the IP addresses of the servers which are permitted to send email messages from mail boxes under the domain. The moment this record propagates worldwide, it will exist on all the DNS servers that route the Internet traffic. Every time a new e-mail message is sent, the initial DNS server it goes through checks if it comes from an authorized server. If it does, it's sent to the destination address, however if it doesn't come from a server part of the SPF record for the domain, it is discarded. Thus nobody can mask an email address and make it look as if you are e-mailing spam. This approach is also referred to as email spoofing.
