SPF, which is short for Sender Policy Framework, is an e-mail protection system, that is used to confirm if an e-mail message is sent by a certified server. Employing SPF protection for a given domain will stop the counterfeiting of email addresses made with the domain. In layman's terms: activating this attribute for a domain makes a specific record in the Domain Name System (DNS) which contains the IP of the servers that are permitted to send e-mails from mail boxes using the domain. Once this record propagates globally, it will exist on all of the DNS servers that direct the Internet traffic. Any time an email message is sent, the initial DNS server it uses checks whether it originates from an authorized server. When it does, it's sent to the destination address, yet when it doesn't come from a server indexed in the SPF record for the domain, it is rejected. In this way nobody will be able to mask an email address and make it appear as if you're e-mailing spam. This method is also termed email spoofing.

SPF Protection in Website Hosting

SPF protection can be activated for every domain name hosted in a website hosting account on our cloud hosting platform with no more than a few mouse-clicks. The option is available in the Emails section of our advanced Hepsia Control Panel and what is needed to activate it is to select one of your domain names from a drop-down list and enter the hostnames and the IPv4 or IPv6 addresses of the email servers which will be authorized to send email messages from your email addresses. As an additional option you can also restrict the messages to be sent from your domain name only when it includes our MX records, in other words when our servers handle the emails for it, not a third-party provider. This option will provide you with the best degree of protection, but it's not applicable when only your website is on our servers while the e-mail addresses for the domain are managed in a different place. In either case, our SPF protection service will keep your email addresses safe from being used for spam and scam purposes.
