SPF, which is short for Sender Policy Framework, is an email security system, which is is intended to verify whether an e-mail message was sent by an official server. Using SPF protection for a particular domain will stop the faking of email addresses generated with the domain. In layman's terms: activating this attribute for a domain name generates a special record in the Domain Name System (DNS) which includes the IP of the servers that are allowed to send email messages from mailboxes under the domain. Once this record propagates worldwide, it exists on all DNS servers that direct the Internet traffic. Every time an e-mail message is sent, the initial DNS server it goes through checks whether it originates from an approved server. If it does, it is forwarded to the destination address, however when it doesn't originate from a server indexed in the SPF record for the domain, it's discarded. In this way nobody will mask an email address then make it look as if you are sending spam messages. This technique is also known as email spoofing.
SPF Protection in Cloud Hosting
SPF protection can be activated for any domain hosted in a cloud hosting account on our cloud platform with no more than a few mouse-clicks. The option is available in the Emails section of our state-of-the-art Hepsia Control Panel and what is needed to enable it is to select one of your domains from a drop-down menu and then type in the hostnames along with the IPv4 or IPv6 addresses of the e-mail servers which will be approved to send emails from your email addresses. As an added option you can even restrict the messages to be sent from your domain only when it includes our MX records, in other words when our servers manage the e-mail addresses for it, not a third-party provider. This solution will give you the highest level of safety, but it is not applicable in case only your website is on our servers while your email addresses for the domain name are handled elsewhere. Either way, our SPF protection service will keep your emails risk-free from being used for spam and scam purposes.
