SPF, which is short for Sender Policy Framework, is an e-mail protection system, which is used to confirm if an email message was sent by an authorized server. Employing SPF protection for a particular domain name will prevent the forging of email addresses made with the domain. In layman's terms: enabling this attribute for a domain name creates a particular record in the Domain Name System (DNS) which includes the IP addresses of the servers that are allowed to send email messages from mailboxes under the domain. As soon as this record propagates globally, it will exist on all DNS servers that route the Internet traffic. When some email message is sent, the first DNS server it uses verifies if it originates from an authorized server. In the event it does, it's sent to the destination address, yet if it doesn't originate from a server listed 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 look as if you are e-mailing spam. This technique is also called 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 just a couple of clicks. The function is available in the Emails section of our outstanding Hepsia Control Panel and what is needed to activate it is to select one of your domain names from the drop-down menu and then type in the hostnames and the IPv4 or IPv6 addresses of the mail servers that will be authorized to send emails from your emails. As an added option you can even restrict the email messages to be sent from your domain name only when it includes our MX records, in other words when our servers manage the e-mail addresses for it, not some third-party supplier. This option provides you with the highest level of security, but it's not applicable when only your web site is on our servers while your emails for the domain are handled somewhere else. Regardless, our SPF protection service will keep your emails risk-free from being used for spam or scam purposes.
