SPF, which is short for Sender Policy Framework, is an e-mail safety system, which is used to validate whether an email message is sent by an authorized server. Employing SPF protection for a given domain name will stop the faking of emails created with the domain. In layman's terms: activating this function for a domain generates a particular record in the Domain Name System (DNS) containing the IP of the servers that are allowed to send e-mail messages from mailboxes under the domain. Once this record propagates worldwide, it exists on all the DNS servers that route the Internet traffic. Whenever a new e-mail message is sent, the first DNS server it uses verifies if it comes from an authorized server. If it does, it is forwarded to the destination address, however if it does not originate from a server listed in the SPF record for the domain, it's rejected. Thus nobody can mask an e-mail address then make it appear as if you're e-mailing spam. This technique is also known as email spoofing.

For those which aren't, you can enable the SPF protection option and set up various things at the same time - the hostnames of the mail servers that are allowed to send messages from your addresses, the IPv4 and IPv6 addresses of the servers, and even to create a rule that messages can be sent only if your domain names include our MX records. The last mentioned choice is the most secure one, and it can be used when we take care of the e-mails for your domains and you're not using some other email service provider.
