SPF, which is short for Sender Policy Framework, is an email protection system, which is is intended to verify if an email message is sent by an official server. Using SPF protection for a particular domain name will stop the forging of emails generated with the domain. In layman's terms: enabling this attribute for a domain name makes a special record in the Domain Name System (DNS) containing the IP of the servers that are allowed to send e-mails from mailboxes under the domain. Once this record propagates worldwide, it will exist on all of the DNS servers that route the Internet traffic. Whenever a new email message is sent, the first DNS server it uses tests if it originates from an official server. If it does, it's forwarded to the destination address, however when it does not come from a server listed in the SPF record for the domain, it's rejected. Thus nobody will mask an e-mail address to make it look as if you are e-mailing spam. This approach is also called email spoofing.
SPF Protection in Shared Web Hosting
SPF protection can be enabled for every domain hosted in a shared web hosting account on our cloud hosting platform with only a few mouse-clicks. The option is accessible in the Emails section of our leading-edge Hepsia Control Panel and all you need to use it is to pick one of your domain names from a drop-down list and enter the hostnames along with the IPv4 or IPv6 addresses of the e-mail servers which will be approved to send messages from your email addresses. As an added option you can also restrict the e-mails to be sent from your domain name only when it includes our MX records, i.e. if our servers handle the e-mail addresses for it, not some third-party supplier. This solution provides you with the top standard of safety, but it's not applicable if only your website is on our servers while the email addresses for the domain name are handled in a different place. In either case, our SPF protection service will keep your email addresses protected from being used for spam and scam purposes.
