SPF, which is an acronym for Sender Policy Framework, is an e-mail security system, which is designed to confirm if an email message is sent by a certified server. Using SPF protection for a given domain will stop the counterfeiting of emails 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 which are permitted to send email messages from mail boxes under the domain. When this record propagates globally, it will exist on all of the DNS servers that route the Internet traffic. When a new email message is sent, the first DNS server it goes through verifies if it originates from an authorized server. In the event 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 domain, it is rejected. In this way nobody can mask an email address to make it look as if you are sending spam. This approach is also referred to as email spoofing.

SPF Protection in Shared Hosting

SPF protection can be enabled for any domain hosted in a shared hosting account on our cloud hosting platform with only a few mouse-clicks. The function can be found in the Emails section of our exceptional Hepsia Control Panel and all it takes to use it is to pick one of your domain names from the drop-down list and to type in the hostnames as well as the IPv4 or IPv6 addresses of the mail servers which will be certified to send emails from your emails. As an additional option you may also restrict the email messages to be sent from your domain name only if it includes our MX records, in other words when our servers manage the emails for it, not some third-party supplier. This feature will give you the highest level of security, but it's not applicable when only your site is on our servers while your e-mail addresses for the domain are handled elsewhere. Either way, our SPF protection service will keep your email addresses safe from being used for spam and scam purposes.
