Sender Policy Framework, or SPF, is a validation system, that is designed to prevent the so-called email spoofing where an email message is sent from one e-mail, but to seem as being sent from a different, often with the purpose to fraud the recipient in some way. If SPF protection is enabled for a domain name, an exclusive record is generated for it in the Domain Name System and all of the DNS servers globally receive it. The record includes all of the email servers that are permitted to send valid messages from an e-mail address part of the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and if the sending server is authorized, the message is sent to the target receiver. When, however, the sending server doesn't exist in the SPF record for the particular domain, the message will not be forwarded and it will be discarded. If you use this solution, it will prevent third parties from sending spam that appear to have been sent from you.
