Sender Policy Framework, or SPF, is a validation system, that is designed to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email, but to look as being sent from a different one, often with the idea to scam the recipient in some way. If SPF protection is enabled for a domain name, a unique record is made for it in the Domain Name System and all DNS servers globally have it. The record features all of the e-mail servers that are allowed to send legitimate messages from an address part of the domain. When an e-mail is sent, the first DNS server it goes to checks the SPF record and if the sending server is permitted, the message is forwarded to the target receiver. In case, however, the sending server is not contained in the SPF record for the particular domain, the e-mail message won't be sent and it will be removed. In case you use this solution, it will prevent third parties from sending spam e-mails which look as if they have been sent from you.

SPF Protection in Cloud Hosting

SPF protection can be activated for each domain hosted in a cloud hosting account on our cloud hosting platform with only a couple of mouse-clicks. The function is accessible in the Emails section of our leading-edge Hepsia Control Panel and all you need to enable it is to choose one of your domain names from a drop-down list and type in the hostnames as well as the IPv4 or IPv6 addresses of the mail servers that will be permitted to send messages from your emails. As an additional option you can also restrict the email messages to be sent from your domain name only if it has our MX records, i.e. if our servers manage the emails for it, not some third-party provider. This solution will provide you with the highest degree of safety, but it's not applicable when only your site is on our servers while your e-mail addresses for the domain are handled somewhere else. Regardless, our SPF protection service will keep your emails safe from being used for spam or scam purposes.

SPF Protection in Semi-dedicated Hosting

When you host your domain names in a semi-dedicated server account with our company, you are able to benefit from the SPF protection feature as part of the standard collection of services that you will get with this kind of website hosting. Starting the protection will require just a couple of easy steps inside the Hepsia Control Panel, therefore even in case you have never employed this type of function before, you will not have any troubles. Using an exceptionally time and effort saving interface, you will just have to enter the information of the mail server that will be authorized to send out messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the recently made record propagates, nobody will be able to forge any e-mail for that particular domain and send email messages from a server different from the one you have entered. This doesn't necessarily have to be our mail server, but if we handle your emails, you are able to enable an extra level of security by selecting an option that email messages can be send out from addresses @your-domain.com only in case the domain uses our MX records. Our technical support team can help you 24/7 in case you have any questions about this service.
