Sender Policy Framework, or SPF, is a validation system, that is employed to stop the so-called e-mail spoofing where an email message is sent from one e-mail, but to seem as being sent from another, often with the idea to scam the recipient for some reason. When SPF protection is enabled for a domain, a unique record is made for it in the Domain Name System and all the DNS servers around the world receive it. The record includes all e-mail servers that are permitted to send valid messages from an e-mail address under the domain. When an email is sent, the very first DNS server it encounters verifies the SPF record and in case the sending server is authorized, the message is forwarded to the target destination. If, however, the sending server is not present in the SPF record for the specified domain, the email message won't be sent and it will be removed. Whenever you employ this service, it will stop third parties from sending spam e-mails that seem to have been sent by you.

SPF Protection in Web Hosting

SPF protection can be enabled for each domain hosted in a web hosting account on our cloud platform with just a few clicks. The option is available in the Emails section of our amazing Hepsia Control Panel and what is needed to use it is to pick one of your domains from the drop-down menu and to type in the hostnames plus the IPv4 or IPv6 addresses of the email servers which will be certified to send email messages from your email addresses. As an added option you may also restrict the email messages to be sent from your domain 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 offers you the top standard of protection, but it's not applicable when only your website is on our servers while your e-mail addresses for the domain are handled in another place. In either case, the SPF protection service will keep your email addresses secure from being used for spam or scam purposes.
