SPF, which means Sender Policy Framework, is an email safety system, which is employed to validate if an email message is sent by an official server. Employing SPF protection for a given domain will prevent the faking of email addresses generated with the domain. In simple words: activating this attribute for a domain creates a particular record in the Domain Name System (DNS) containing the IP addresses of the servers that are permitted to send emails from mailboxes under the domain. Once this record propagates globally, it exists on all DNS servers that direct the Internet traffic. When a new e-mail message is sent, the initial DNS server it goes through tests if it comes from an approved server. When it does, it is sent to the destination address, however when it doesn't originate from a server part of the SPF record for the particular domain, it's rejected. Thus nobody can mask an e-mail address to make it look as if you are sending spam messages. This technique is also referred to as email spoofing.

SPF Protection in Cloud Web Hosting

SPF protection can be enabled for each domain hosted in a cloud web hosting account on our cloud platform with no more than a couple of clicks. The function can be found in the Emails section of our exceptional Hepsia Control Panel and all you need to enable it is to pick one of your domain names from the drop-down list and then type in the hostnames together with the IPv4 or IPv6 addresses of the mail servers which will be certified to send email messages from your email addresses. As an added option you may also restrict the messages to be sent from your domain name only when it has our MX records, in other words when our servers manage the email addresses for it, not a third-party supplier. This feature gives you the highest level of security, but it is not applicable in case only your website is on our servers while the emails for the domain name are taken care of in a different place. Regardless, the SPF protection service will keep your emails secure from being used for spam or scam purposes.
