Sender Policy Framework, or SPF, is a verification system, that is designed to stop the so-called email spoofing where an email message can be sent from one e-mail address, but to seem as being sent from a different one, usually with the purpose to scam the recipient someway. When SPF protection is activated for a domain, a specific record is generated for it in the Domain Name System and all the DNS servers globally receive it. The record features all of the mail servers that are permitted to send authentic messages from an email address within the domain. When an email is sent, the first DNS server it goes to checks the SPF record and in case its sending server is authorized, the message is forwarded to the target receiver. In case, however, the sending server is not contained in the SPF record for the specified domain, the message will not be sent and it will be removed. When you employ this solution, it'll stop third parties from sending spam messages which appear to have been sent from you.

SPF Protection in Cloud Hosting

SPF protection can be enabled for each domain hosted in a cloud hosting account on our cloud platform with only a couple of mouse-clicks. The function is available in the Emails section of our cutting-edge Hepsia Control Panel and all it takes to enable it is to select one of your domains from a drop-down list and enter the hostnames plus the IPv4 or IPv6 addresses of the email servers that will be authorized to send messages from your emails. As an additional option you may also restrict the e-mails to be sent from your domain name only if it includes our MX records, in other words when our servers handle the e-mail addresses for it, not a third-party supplier. This feature will give you the best degree of protection, but it's not applicable when only your website is on our servers while your email addresses for the domain name are handled somewhere else. Either way, our SPF protection service will keep your email addresses protected from being used for spam and scam purposes.
