SPF, which stands for Sender Policy Framework, is an e-mail safety system, which is designed to validate if an e-mail message was sent by an official server. Using SPF protection for a particular domain will stop the faking of emails made with the domain. In simple words: enabling this attribute for a domain makes a specific record in the Domain Name System (DNS) containing the IP of the servers that are allowed to send e-mails from mail boxes under the domain. Once this record propagates worldwide, it will exist on all of the DNS servers that route the Internet traffic. When a new e-mail message is sent, the first DNS server it goes through tests whether it comes from an official server. In the event it does, it is sent to the destination address, yet when it does not come from a server listed in the SPF record for the particular domain, it's rejected. In this way nobody will mask an e-mail address to make it look as if you are e-mailing spam messages. This approach is also called email spoofing.
SPF Protection in Hosting
SPF protection can be enabled for every domain hosted in a hosting account on our cloud hosting platform with just a couple of mouse-clicks. The feature is available in the Emails section of our amazing Hepsia Control Panel and what is needed to use it is to pick one of your domains from a drop-down menu and to type in the hostnames plus the IPv4 or IPv6 addresses of the e-mail servers that will be approved to send messages from your emails. As an additional option you can also restrict the emails to be sent from your domain name only if it has our MX records, in other words when our servers handle the emails for it, not some third-party supplier. This option offers you the best degree of safety, but it is not applicable when only your website is on our servers while your e-mail addresses for the domain name are handled somewhere else. Regardless, our SPF protection service will keep your email addresses protected from being used for spam or scam purposes.
