SPF, which is an acronym for Sender Policy Framework, is an email safety system, that is used to confirm whether an email message was sent by an official server. Using SPF protection for a particular domain name will stop the faking of emails made with the domain. In layman's terms: enabling this feature for a domain creates a particular record in the Domain Name System (DNS) which contains the IP of the servers that are allowed to send emails from mail boxes using the domain. Once this record propagates worldwide, it will exist on all the DNS servers that direct the Internet traffic. When some e-mail message is sent, the initial DNS server it uses tests if it comes from an accredited server. When it does, it is forwarded to the destination address, yet if it does not come from a server listed in the SPF record for the domain, it is rejected. In this way nobody can mask an e-mail address to make it look as if you're e-mailing spam messages. This method is also known as email spoofing.

SPF Protection in Shared Website Hosting

When you host your domains in a shared website hosting account on our end and we manage the emails for them, you'll be able to enable SPF protection for them with several clicks in your Hepsia Control Panel. The service can be found in its own section where you will be able to view which domains are currently secured. For those that are not, you will be able to activate the SPF protection option and configure a number of things in the process - the hostnames of the mail servers that are allowed to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, and to create a rule that emails can be sent only if your domains include our MX records. The last mentioned option is the most secure one, and you can use it in the event that we manage the e-mails for your domain names and you are not using a different e-mail provider. The newly generated records will be activated within one day and nobody will be able to forge the FROM field in an e-mail by using your addresses.
