Sender Policy Framework, or SPF, is a validation system, that is used to prevent the so-called email spoofing where an email message can be sent from one email address, but to look as being sent from a different, typically with the idea to fraud the recipient someway. When SPF protection is activated for a domain, a special record is generated for it in the Domain Name System and all DNS servers worldwide have it. The record includes all the mail servers that are allowed to send valid messages from an email address within the domain. When an email is sent, the very first DNS server it encounters verifies the SPF record and in case the sending server is authorized, the message is sent to the targeted destination. In case, however, the sending server doesn't exist in the SPF record for the specified domain, the email message will not be sent and it will be removed. If you employ this service, it will stop third parties from sending spam e-mails which look as if they have been sent from you.

Using a really time and effort saving interface, all you'll have to submit is the hostname of the mail server which will be accredited to send out messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you are able to add several servers as well, when needed. In case your email addresses are managed on our end, you may also take advantage of a more risk-free option by placing a limit that email messages can be sent only when your domain names have our MX records. This option cannot be applied if your site is hosted here, and the emails are with a third-party service provider. In either case, the SPF protection option can significantly increase your web security and prevent others from forging your e-mail addresses.
