SPF, which stands for Sender Policy Framework, is an email security system, which is employed to validate whether an email message was sent by an authorized server. Employing SPF protection for a given domain name will stop the forging of emails generated with the domain. In layman's terms: enabling this function for a domain creates a special record in the Domain Name System (DNS) containing the IP of the servers that are allowed to send emails from mailboxes under the domain. As soon as this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. When an e-mail message is sent, the initial DNS server it goes through checks whether it originates from an approved server. If it does, it is sent to the destination address, yet when it does not originate from a server indexed in the SPF record for the domain, it is discarded. In this way nobody will mask an email address then make it look as if you are sending spam messages. This method is also termed email spoofing.
SPF Protection in Shared Web Hosting
SPF protection can be enabled for every domain hosted in a shared web hosting account on our cloud platform with only a couple of mouse-clicks. The option is available in the Emails section of our revolutionary Hepsia Control Panel and all it takes to enable it is to choose one of your domains from the drop-down menu and then enter the hostnames together with the IPv4 or IPv6 addresses of the mail servers which will be certified to send messages from your email addresses. As an additional option you may also restrict the messages to be sent from your domain only when it has our MX records, i.e. if our servers manage the email addresses for it, not some third-party supplier. This option provides you with the highest degree of security, but it's not applicable when only your site is on our servers while your e-mail addresses for the domain name are handled in a different place. In either case, our SPF protection service will keep your emails protected from being used for spam and scam purposes.
