Sender Policy Framework, or SPF, is a validation system, which is designed to prevent the so-called e-mail spoofing where an email message is sent from one e-mail, but to seem as being sent from another one, usually with the idea to scam the recipient in some way. If SPF protection is activated for a domain, a special record is generated for it in the Domain Name System and all the DNS servers globally get it. The record contains all of the e-mail servers that are permitted to send legitimate messages from an address part of the domain. When an e-mail is sent, the first DNS server it encounters checks the SPF record and when the sending server is authorized, the message is sent to the targeted destination. In case, however, the sending server is not included in the SPF record for the given domain, the e-mail message will not be forwarded and it will be removed. If you employ this service, it'll prevent third parties from sending spam messages that appear to have been sent by you.
