SPF, which is short for Sender Policy Framework, is an e-mail security system, that is used to confirm whether an email message is sent by an official server. Using SPF protection for a particular domain will prevent the counterfeiting of emails generated with the domain. In layman's terms: activating this attribute for a domain makes a particular record in the Domain Name System (DNS) which contains the IP addresses of the servers which are allowed to send email messages from mailboxes under the domain. When this record propagates worldwide, it will exist on all DNS servers that route the Internet traffic. Every time an email message is sent, the first DNS server it uses verifies if it comes from an accredited server. In the event it does, it is forwarded to the destination address, but when it does not originate from a server listed in the SPF record for the particular domain, it's rejected. In this way nobody will mask an e-mail address then make it appear as if you are distributing spam. This approach is also called email spoofing.

SPF Protection in Cloud Web Hosting

SPF protection can be activated for every domain name hosted in a cloud web hosting account on our cloud platform with just a few clicks. The function can be found in the Emails section of our advanced Hepsia Control Panel and what is needed to activate it is to pick one of your domain names from a drop-down menu and enter the hostnames and the IPv4 or IPv6 addresses of the mail servers which will be certified to send messages from your emails. As an added option you may also restrict the emails to be sent from your domain name only when it includes our MX records, in other words when our servers manage the emails for it, not some third-party provider. This solution gives you the best level of protection, but it's not applicable when only your web site is on our servers while your email addresses for the domain are managed in another place. In either case, the SPF protection service will keep your email addresses safe from being used for spam and scam purposes.
