Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called e-mail spoofing where an e-mail message can be sent from one e-mail address, but to appear as being sent from a different, ordinarily with the idea to fraud the recipient in some way. If SPF protection is enabled for a domain name, an exclusive record is made for it in the Domain Name System and all the DNS servers globally receive it. The record includes all email servers that are allowed to send legitimate messages from an e-mail address within the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and when the sending server is authorized, the message is forwarded to the targeted receiver. In case, however, the sending server is not included in the SPF record for the specified domain, the email message will not be submitted and it'll be discarded. Whenever you employ this solution, it'll prevent third parties from sending spam which seem to have been sent from you.

SPF Protection in Web Hosting

SPF protection can be enabled for every domain name hosted in a web hosting account on our cloud hosting platform with just a few mouse-clicks. The function is accessible in the Emails section of our revolutionary Hepsia Control Panel and all you need to activate it is to pick one of your domain names from the drop-down menu and then type in the hostnames and the IPv4 or IPv6 addresses of the email servers which will be permitted to send messages from your emails. As an added option you may also restrict the email messages to be sent from your domain name only when it has our MX records, in other words when our servers manage the e-mail addresses for it, not some third-party supplier. This option offers you the top standard of safety, but it is not applicable when only your website is on our servers while your email addresses for the domain are taken care of in a different place. Regardless, the SPF protection service will keep your email addresses safe from being used for spam or scam purposes.
