Sender Policy Framework, or SPF, is a validation system, which is employed to prevent the so-called e-mail spoofing where an email message is sent from one e-mail, but to appear as being sent from another one, typically with the idea to scam the recipient someway. If SPF protection is enabled for a domain, a unique record is created for it in the Domain Name System and all of the DNS servers around the world get it. The record includes all e-mail servers that are allowed to send valid messages from an address within the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and when its sending server is authorized, the message is sent to the target destination. In case, however, the sending server is not contained in the SPF record for the specified domain, the message will not be forwarded and it'll be removed. When you use this service, it'll prevent third parties from sending spam emails that seem to have been sent by you.

SPF Protection in Cloud Website Hosting

When you host your domain names in a cloud website hosting account with us and we handle the email addresses for them, you are able to enable SPF protection for all of them with several clicks in your Hepsia Control Panel. The service can be found in its own section where you can view which domains are currently secured. For the ones that are not, you can activate the SPF protection option and configure a variety of things at the same time - the hostnames of the mail servers that are permitted to send messages from your emails, the IPv4 and IPv6 addresses of these servers, and even to set a rule that email messages can be sent only if your domain names have our MX records. The aforementioned solution is the most secure one, but it can be used in the event that we take care of the e-mails for your domains and do not use a different e-mail supplier. The newly created records will propagate within 24 hours and nobody will be able to fake the FROM field in a message by using your addresses.
