SPF

SPF or Sender Policy Framework fights e-mail forgery. It prevents unauthorized people from forging your email address. When you enable SPF, a DNS record is created to define IPs allowed to send mail from your mail domain. On receiving an e-mail from your mail domain, correspondent’s server checks if the IP address that the e-mail’s come from is listed in your SPF DNS record. If it’s not, the e-mail will be rejected or flagged as suspicious.

E-mails sent to your mail domain will undergo similar check-up. Provided SPF in enabled on the sender’s mail domain, e-mails coming from the IP that isn’t listed in the senders SPF DNS record, will be rejected or flagged as suspicious according to your SPF policy configuration
