SPF, which stands for Sender Policy Framework, is an email security system, that is designed to validate if an email message is sent by a licensed server. Using SPF protection for a domain will prevent the faking of email addresses generated with the domain. In simple words: enabling this function for a domain name generates a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers which are allowed to send emails from mailboxes using the domain. As soon as this record propagates globally, it exists on all the DNS servers that direct the Internet traffic. Every time an e-mail message is sent, the initial DNS server it goes through tests whether it originates from an approved server. In the event it does, it is forwarded to the destination address, but if it does not come from a server part of the SPF record for the domain, it is rejected. In this way nobody will mask an e-mail address to make it appear as if you are e-mailing spam messages. This technique is also known as email spoofing.
SPF Protection in Cloud Web Hosting
SPF protection can be activated for every domain hosted in a cloud web hosting account on our cloud hosting platform with only a few clicks. The feature can be found in the Emails section of our leading-edge Hepsia Control Panel and what is needed to activate it is to choose one of your domain names from the drop-down menu and type in the hostnames as well as the IPv4 or IPv6 addresses of the mail servers that will be authorized to send messages from your emails. As an added option you can even restrict the messages to be sent from your domain only if it has our MX records, in other words when our servers handle the emails for it, not some third-party provider. This solution offers you the best degree of security, but it's not applicable if only your web site is on our servers while your e-mail addresses for the domain are managed in another place. Regardless, the SPF protection service will keep your email addresses secure from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Servers
When you host your domains in a semi-dedicated server account from our company, you can use the SPF protection feature as a part of the regular set of services that you will get using this kind of hosting. Starting the protection involves only a few easy steps inside the Hepsia Control Panel, therefore even in the event that you have never used such a function before, you won't have any kind of issues. Through a very intuitive interface, you will simply need to insert the details of the mail server which will be authorized to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the recently made record propagates, no one will be able to forge any email address for that particular domain and send out messages from a server other than the one you've entered. This doesn't necessarily have to be our mail server, yet in case we handle your e-mails, you will be able to allow an additional level of security by selecting an option that e-mails can be send from addresses @your-domain.com only if the domain uses our MX records. Our technical support team will be able to help you 24/7 in case you have any kind of questions regarding this service.
