Sender Policy Framework, or SPF, is a validation system, that is employed to stop the so-called email spoofing where an email message is sent from one address, but to look as being sent from a different one, ordinarily with the objective to scam the recipient in some way. When SPF protection is activated for a domain, a special record is generated for it in the Domain Name System and all the DNS servers around the world receive it. The record features all mail servers that are allowed to send valid messages from an address under the domain. When an e-mail is sent, the very first DNS server it encounters checks the SPF record and when the sending server is authorized, the message is sent to the targeted destination. When, however, the sending server is not contained in the SPF record for the specified domain, the email message will not be submitted and it will be removed. When you use this solution, it'll prevent third parties from sending spam that appear to have been sent by you.
