What is SPF?
SPF (Sender Policy Framework) is a sender authentication method through which the administrator can specify which hosts are allowed to send email on behalf of a domain. The sending domain adds a specially formatted record into its DNS zone file identifying all authorized mail servers. The receiving mail server checks the sending domain's DNS zone file to see if the IP address from which the message originates matches one of the authorized IP addresses.
