SPF, which stands for Sender Policy Framework, is an email protection system, that is is intended to validate whether an e-mail message was sent by an authorized server. Employing SPF protection for a particular domain will stop the faking of emails created with the domain. In simple words: enabling this function for a domain name makes a particular record in the Domain Name System (DNS) that contains the IP of the servers which are allowed to send email messages from mailboxes under the domain. Once this record propagates globally, it exists on all the DNS servers that direct the Internet traffic. Whenever some email message is sent, the initial DNS server it goes through verifies whether it originates from an authorized server. In the event it does, it's forwarded to the destination address, however when it doesn't originate from a server listed in the SPF record for the domain, it's rejected. Thus nobody will mask an email address and make it appear as if you're sending spam. This approach is also referred to as email spoofing.

SPF Protection in Shared Hosting

SPF protection can be activated for each domain hosted in a shared hosting account on our cloud hosting platform with only a few clicks. The feature is available in the Emails section of our leading-edge Hepsia Control Panel and all you need to enable it is to select one of your domains from a drop-down menu and then type in the hostnames as well as the IPv4 or IPv6 addresses of the mail servers which will be certified to send messages from your emails. As an added option you can even restrict the e-mails to be sent from your domain only if it has our MX records, in other words if our servers handle the email addresses for it, not some third-party supplier. This solution provides you with the best degree of security, but it's not applicable in case only your web site is on our servers while the e-mail addresses for the domain name are managed somewhere else. Either way, the SPF protection service will keep your email addresses protected from being used for spam or scam purposes.
