SPF, which means Sender Policy Framework, is an email security system, that is employed to confirm if an email message was sent by a licensed server. Employing SPF protection for a domain name will stop the faking of emails made with the domain. In layman's terms: enabling this function for a domain name creates a special record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send e-mails from mailboxes under the domain. The moment this record propagates globally, it will exist on all of the DNS servers that direct the Internet traffic. Whenever some e-mail message is sent, the initial DNS server it uses verifies whether it comes from an accredited server. When it does, it's sent to the destination address, however when it does not originate from a server listed in the SPF record for the particular domain, it is discarded. In this way nobody will be able to mask an e-mail address to make it look as if you are e-mailing spam. This approach is also called email spoofing.
SPF Protection in Shared Hosting
SPF protection can be enabled for every domain hosted in a shared hosting account on our cloud hosting platform with just a couple of clicks. The function is available in the Emails section of our revolutionary Hepsia Control Panel and all it takes to use it is to pick one of your domains from the drop-down list and to enter the hostnames together with the IPv4 or IPv6 addresses of the mail servers that will be permitted to send emails from your emails. As an additional option you may also restrict the messages to be sent from your domain name only if it has our MX records, in other words when our servers manage the e-mail addresses for it, not some third-party supplier. This feature provides you with the highest degree of security, but it is not applicable if only your website is on our servers while the email addresses for the domain are managed in a different place. Either way, our SPF protection service will keep your email addresses safe from being used for spam or scam purposes.
