Email spoofing occurs when spammers make the return email address appear to be a trusted address, such as your domain. Sender Policy Framework (SPF) validates message origins to prevent spoof messages from appearing as though they originated from your domain. According to H-Sphere, a Web and email server utility, "SPF is a mechanism for preventing sender forgery in SMTP transaction, thus allowing domain owners control over who may send mail from their domain

If your firewall detects a forgery or potential forgery, it will attach a prefix to the message. Select "Fail" to instruct the firewall to mark messages are a forgery if SPF detects a spoof. Select "Softfail" to mark spoof messages as potential forgeries. cPanel users will see options to allow additional hosts, IP addresses and servers to send messages from your email service. Click the buttons to "Add" or "Remove" appropriate hosts. Domain owners can apply the same settings for all domains by checking "Overwrite Existing Entries."
