Sender Policy Framework, or SPF, is a validation system, which is designed to stop the so-called e-mail spoofing where an e-mail message can be sent from one e-mail, but to appear as being sent from a different, often with the idea to fraud the recipient for some reason. If SPF protection is activated for a domain name, a unique record is generated for it in the Domain Name System and all of the DNS servers around the world receive it. The record features all of the e-mail servers that are permitted to send valid messages from an address under the domain. When an e-mail is sent, the very first DNS server it goes to checks the SPF record and when its sending server is authorized, the message is sent to the target receiver. In case, however, the sending server is not contained in the SPF record for the specified domain, the email message will not be sent and it'll be removed. If you employ this service, it'll prevent third parties from sending spam that appear to have been sent from you.
SPF Protection in Shared Website Hosting
SPF protection can be enabled for every domain name hosted in a shared website hosting account on our cloud platform with just a couple of clicks. The feature is available in the Emails section of our state-of-the-art Hepsia Control Panel and all you need to use it is to choose one of your domains from a drop-down menu and to enter the hostnames and the IPv4 or IPv6 addresses of the e-mail servers which will be certified to send email messages from your email addresses. As an additional option you may also restrict the e-mails to be sent from your domain only when it includes our MX records, i.e. when our servers handle the e-mail addresses for it, not some third-party provider. This option gives you the top standard of safety, but it is not applicable in case only your website is on our servers while your e-mail addresses for the domain are handled in a different place. Regardless, our SPF protection service will keep your emails risk-free from being used for spam and/or scam purposes.
