SPF, which is short for Sender Policy Framework, is an e-mail protection system, that is designed to confirm whether an email message was sent by a licensed server. Employing SPF protection for a given domain name will prevent the counterfeiting of emails generated with the domain. In layman's terms: activating this feature for a domain makes a particular record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send emails from mail boxes using the domain. As soon as this record propagates globally, it will exist on all of the DNS servers that route the Internet traffic. Every time a new e-mail message is sent, the initial DNS server it uses checks if it comes from an official server. When it does, it's forwarded to the destination address, yet when it doesn't originate from a server indexed in the SPF record for the domain, it's discarded. Thus nobody can mask an email address to make it appear as if you're sending spam messages. This technique is also identified as email spoofing.

SPF Protection in Shared Website Hosting

SPF protection can be enabled for each domain name hosted in a shared website hosting account on our cloud hosting platform with only a few mouse-clicks. The option is accessible in the Emails section of our cutting-edge Hepsia Control Panel and what is needed to enable it is to select one of your domains from a drop-down list and enter the hostnames together with the IPv4 or IPv6 addresses of the e-mail servers which will be approved to send messages from your emails. As an added option you may also restrict the e-mails to be sent from your domain only if it has our MX records, i.e. when our servers handle the emails for it, not a third-party provider. This feature will provide you with the top level of security, but it's not applicable if only your website is on our servers while your e-mail addresses for the domain name are handled in another place. Either way, our SPF protection service will keep your emails safe from being used for spam and/or scam purposes.
