Sender Policy Framework, or SPF, is a validation system, which is used to stop the so-called e-mail spoofing where an e-mail message can be sent from one email, but to appear as being sent from a different one, ordinarily with the objective to fraud the recipient for some reason. When SPF protection is enabled for a domain, a special record is made for it in the Domain Name System and all DNS servers worldwide get it. The record includes all the email servers that are permitted to send legitimate messages from an address part of the domain. When an e-mail is sent, the very first DNS server it goes to verifies the SPF record and when the sending server is permitted, the message is forwarded to the targeted destination. When, however, the sending server is not included in the SPF record for the specified domain, the email message won't be forwarded and it'll be removed. If you employ this service, it will stop third parties from sending spam e-mails which look as if they have been sent from you.

SPF Protection in Website Hosting

SPF protection can be activated for any domain name hosted in a website hosting account on our cloud platform with no more than a few clicks. The feature is available in the Emails section of our modern Hepsia Control Panel and what is needed to use it is to select one of your domain names from the drop-down list and to enter the hostnames plus the IPv4 or IPv6 addresses of the mail servers which will be authorized to send emails from your emails. As an additional option you may also restrict the email messages to be sent from your domain name only when it includes our MX records, i.e. when our servers manage the emails for it, not some third-party supplier. This option will provide you with the highest level of safety, but it's not applicable when only your site is on our servers while your email addresses for the domain are handled somewhere else. In either case, our SPF protection service will keep your emails safe from being used for spam and scam purposes.
