SPF, which is an acronym for Sender Policy Framework, is an email security system, which is is intended to confirm if an email message is sent by a licensed server. Using SPF protection for a domain name will prevent the forging of email addresses made with the domain. In layman's terms: activating this function for a domain creates a special record in the Domain Name System (DNS) containing the IP of the servers which are allowed to send e-mail messages from mailboxes using the domain. Once this record propagates globally, it exists on all DNS servers that direct the Internet traffic. When a new email message is sent, the first DNS server it goes through checks whether it originates from an approved server. When it does, it is sent to the destination address, yet if it does not come from a server part of the SPF record for the domain, it is discarded. In this way nobody will be able to mask an email address to make it look as if you're distributing spam. This technique is also known as email spoofing.
SPF Protection in Cloud Hosting
SPF protection can be enabled for any domain name hosted in a cloud hosting account on our cloud hosting platform with only a couple of clicks. The function can be found in the Emails section of our state-of-the-art Hepsia Control Panel and all it takes to activate it is to select one of your domains from the drop-down list and type in the hostnames together with the IPv4 or IPv6 addresses of the e-mail servers which will be permitted to send email messages from your email addresses. As an added option you may also restrict the e-mails to be sent from your domain name only when it includes our MX records, i.e. if our servers manage the emails for it, not some third-party provider. This feature gives you the highest standard of security, but it is not applicable when only your site is on our servers while the emails for the domain name are taken care of in a different place. Either way, the SPF protection service will keep your email addresses secure from being used for spam and scam purposes.
