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 address, but to appear as being sent from a different one, typically with the objective to scam the recipient for some reason. If SPF protection is enabled for a domain, an exclusive record is created for it in the Domain Name System and all of the DNS servers around the world receive it. The record includes all of the e-mail servers that are permitted to send legitimate messages from an address part of the domain. When a message is sent, the very first DNS server it encounters verifies the SPF record and if the sending server is authorized, the message is sent to the targeted destination. In case, however, the sending server is not present in the SPF record for the specified domain, the email message won't be submitted and it'll be removed. Whenever you use this service, it'll stop third parties from sending spam that look as if they have been sent from you.

SPF Protection in Web Hosting

SPF protection can be activated for every domain hosted in a web hosting account on our cloud hosting platform with just a few clicks. The option can be found in the Emails section of our advanced Hepsia Control Panel and all you need to use it is to select one of your domain names from a drop-down menu and enter the hostnames as well as the IPv4 or IPv6 addresses of the email servers which will be authorized to send messages from your email addresses. As an added option you can also restrict the email messages to be sent from your domain only if it has our MX records, in other words if our servers handle the e-mail addresses for it, not a third-party provider. This solution will provide you with the best degree of safety, but it is not applicable in case only your web site is on our servers while the email addresses for the domain are taken care of elsewhere. Regardless, the SPF protection service will keep your email addresses risk-free from being used for spam and scam purposes.

SPF Protection in Semi-dedicated Hosting

If you host your domain names in a semi-dedicated server account with us, you are able to use the SPF protection feature as a part of the regular set of services that you will get with this kind of hosting. Starting the protection requires just a few easy steps inside the Hepsia Control Panel, thus even when you've never employed such a feature before, you will not have any troubles. Employing a very time and effort saving interface, you'll simply have to insert the information of the mail server which will be authorized to send messages from your addresses - its hostname ( and IP address (IPv4 or IPv6). As soon as the newly generated record propagates, nobody will be able to forge any email address for that particular domain name and send out e-mail messages from a server other than the one you've typed in. This does not specifically have to be our mail server, still in case we manage your e-mails, you can allow an additional level of protection by choosing an option that emails can be send out from addresses only in case the domain uses our MX records. Our technical support staff will be able to help you 24/7 in case you have any questions about this service.
