SPF stands for Sender Policy Framework, and is an extension of SMTP that stops e-mail spammers from forging the "From" fields in an e-mail. As SMTP itself does not carry an authenticating mechanism, the SPF extension provides the authentication scheme by specifying which computers are authorized to send email from a specific domain. In order to use SPF, the domain sending e-mails must establish an SPF record that is published in the DNS records. When the e-mail passes through the DNS server, it is compared to the SPF record for that domain to determine if the sender is indeed authorized to transmit e-mails from that sender's address. If the e-mail comes from a domain that is not authorized, the DNS server will not forward the e-mail to the expected destination. Please note that these settings are for advanced users only! For more detailed information, you may check the Show/Hide Help in the SPF section itself.
