SPF, which is short for Sender Policy Framework, is an e-mail security system, which is designed to verify if an e-mail message is sent by a licensed server. Using SPF protection for a given domain will prevent the faking of email addresses created with the domain. In layman's terms: enabling this feature for a domain makes a particular record in the Domain Name System (DNS) that contains the IP of the servers that are permitted to send email messages from mailboxes using the domain. Once this record propagates worldwide, it will exist on all DNS servers that route the Internet traffic. When some email message is sent, the first DNS server it goes through tests whether it originates from an accredited server. When it does, it is sent to the destination address, however when it does not come from a server part of the SPF record for the particular domain, it's discarded. In this way nobody can mask an e-mail address to make it appear as if you're distributing spam. This approach is also termed email spoofing.

SPF Protection in Cloud Hosting

SPF protection can be enabled for every domain name hosted in a cloud hosting account on our cloud platform with only a few mouse-clicks. The feature can be found in the Emails section of our outstanding Hepsia Control Panel and what is needed to activate it is to pick one of your domains from a drop-down list and to type in the hostnames as well as the IPv4 or IPv6 addresses of the e-mail servers that will be certified to send email messages from your emails. As an added option you can even restrict the messages to be sent from your domain only when it includes our MX records, i.e. if our servers manage the e-mail addresses for it, not some third-party supplier. This option will give you the best degree of security, but it is not applicable when only your website is on our servers while your emails for the domain name are taken care of in another place. Either way, the SPF protection service will keep your emails protected from being used for spam and scam purposes.
