SPF, which is short for Sender Policy Framework, is an e-mail protection system, which is designed to confirm if an e-mail message was sent by a certified server. Using SPF protection for a particular domain name will prevent the counterfeiting of email addresses made with the domain. In layman's terms: activating this function for a domain creates a special record in the Domain Name System (DNS) containing the IP addresses of the servers that are allowed to send emails from mail boxes under the domain. As soon as this record propagates worldwide, it will exist on all the DNS servers that direct the Internet traffic. Any time a new email message is sent, the first DNS server it uses tests if it comes from an authorized server. When it does, it's sent to the destination address, but when it does not originate from a server part of the SPF record for the particular domain, it is rejected. Thus nobody will mask an email address then make it look as if you're sending spam messages. This method is also known as email spoofing.

SPF Protection in Hosting

SPF protection can be activated for each domain hosted in a hosting account on our cloud platform with only a couple of mouse-clicks. The feature can be found in the Emails section of our advanced Hepsia Control Panel and all it takes to enable it is to pick one of your domain names from a drop-down list and enter the hostnames along with the IPv4 or IPv6 addresses of the email servers that will be permitted to send email messages from your emails. As an added option you may also restrict the messages to be sent from your domain name only when it includes our MX records, in other words if our servers manage the e-mail addresses for it, not some third-party provider. This option will give you the best level of safety, but it is not applicable if only your website is on our servers while the e-mail addresses for the domain name are managed in another place. Regardless, our SPF protection service will keep your emails safe from being used for spam and scam purposes.

SPF Protection in Semi-dedicated Servers

If you host your domain names in a semi-dedicated server account from us, you are able to use the SPF protection feature as part of the conventional group of services that you will receive using this kind of website hosting. Activating the protection will involve only a few simple steps inside the Hepsia Control Panel, so that even in the event that you've never used this kind of function before, you will not have any type of troubles. Through an exceptionally user-friendly interface, you will only have to enter the details of the mail server which will be permitted to send out messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the recently generated record propagates, no one will be able to counterfeit any e-mail address for that particular domain and send out emails from a server other than the one you've entered. This does not specifically have to be our mail server, yet if we take care of your emails, you can allow an additional level of security by picking an option that emails can be send from addresses @your-domain.com only if the domain uses our MX records. Our technical support team can assist you 24/7 in case you have any kind of questions related to this service.
