Sender Policy Framework, or SPF, is a validation system, that is intended to prevent the so-called e-mail spoofing where an email message is sent from one email, but to appear as being sent from a different one, frequently with the idea to scam the recipient someway. When SPF protection is enabled for a domain name, a special record is generated for it in the Domain Name System and all of the DNS servers worldwide get it. The record features all mail servers that are allowed to send valid messages from an e-mail address within the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and if its sending server is permitted, the message is sent to the target destination. In case, however, the sending server doesn't exist in the SPF record for the particular domain, the message won't be sent and it'll be removed. Whenever you use this solution, it will stop third parties from sending spam messages which seem to have been sent by you.

SPF Protection in Shared Website Hosting

SPF protection can be activated for each domain hosted in a shared website hosting account on our cloud hosting platform with only a few mouse-clicks. The option is available in the Emails section of our state-of-the-art Hepsia Control Panel and all it takes to use it is to pick one of your domain names from a drop-down list and to enter the hostnames and the IPv4 or IPv6 addresses of the email servers that will be approved to send messages from your email addresses. As an added option you can also restrict the e-mails to be sent from your domain only if it has our MX records, in other words when our servers manage the e-mail addresses for it, not some third-party provider. This feature provides you with the top level of security, but it is not applicable when only your site is on our servers while your email addresses for the domain name are handled in another place. Either way, our SPF protection service will keep your email addresses risk-free from being used for spam and/or scam purposes.

SPF Protection in Semi-dedicated Servers

When you host your domains in a semi-dedicated server account with us, you can benefit from the SPF protection feature as a part of the conventional set of services that you'll receive using this kind of website hosting. Starting the protection requires only a couple of easy steps in the Hepsia Control Panel, so even in the event that you haven't employed this kind of feature before, you will not have any kind of troubles. Through an exceptionally intuitive interface, you'll simply need to input the info of the mail server that will be certified to send out messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the recently generated record propagates, no one will be able to fake any e-mail address for that particular domain name and send out email messages from a server different from the one you've entered. This does not necessarily have to be our mail server, still if we manage your email messages, you're able to enable one more level of protection by picking an option that e-mail messages can be send from addresses @your-domain.com only if the domain employs our MX records. Our technical support staff can help you 24/7 in case you have any kind of questions related to this service.
