SPF, which stands for Sender Policy Framework, is an email safety system, which is employed to confirm whether an email message was sent by an authorized server. Using SPF protection for a particular domain will stop the counterfeiting of emails generated with the domain. In simple words: activating this attribute for a domain name creates a particular record in the Domain Name System (DNS) which contains the IP addresses of the servers that are allowed to send e-mails from mailboxes using the domain. As soon as this record propagates worldwide, it will exist on all of the DNS servers that route the Internet traffic. When a new e-mail message is sent, the initial DNS server it goes through checks if it comes from an official server. In the event it does, it's forwarded to the destination address, however if it doesn't come from a server part of the SPF record for the domain, it's discarded. Thus nobody can mask an e-mail address then make it appear as if you're e-mailing spam. This technique is also termed email spoofing.

SPF Protection in Hosting

SPF protection can be enabled for any domain hosted in a hosting account on our cloud hosting platform with just a couple of clicks. The feature can be found in the Emails section of our revolutionary Hepsia Control Panel and what is needed to enable it is to select one of your domain names from the drop-down list and to type in the hostnames plus the IPv4 or IPv6 addresses of the 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 if it includes our MX records, i.e. when our servers handle the e-mail addresses for it, not some third-party provider. This solution gives you the highest standard of safety, but it's not applicable in case only your website is on our servers while the emails for the domain are taken care of in a different place. In either case, the SPF protection service will keep your emails safe from being used for spam or scam purposes.
