SPF, which is short for Sender Policy Framework, is an e-mail protection system, that is employed to verify whether an e-mail message was sent by an official server. Employing SPF protection for a particular domain will prevent the forging of email addresses generated with the domain. In layman's terms: activating this attribute for a domain name generates a specific record in the Domain Name System (DNS) which includes the IP addresses of the servers which are permitted to send email messages from mail boxes under the domain. Once this record propagates worldwide, it exists on all the DNS servers that route the Internet traffic. Any time an e-mail message is sent, the initial DNS server it uses checks if it comes 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 listed in the SPF record for the particular domain, it's rejected. Thus nobody can mask an e-mail address and make it appear as if you're sending spam messages. This approach is also identified as email spoofing.

SPF Protection in Web Hosting

SPF protection can be activated for any domain hosted in a web hosting account on our cloud hosting platform with only a couple of mouse-clicks. The feature is available in the Emails section of our outstanding Hepsia Control Panel and all you need to enable it is to pick one of your domains from the drop-down list and then type in the hostnames together with the IPv4 or IPv6 addresses of the e-mail servers that will be permitted to send messages from your email addresses. As an additional option you may also restrict the emails to be sent from your domain name only when it includes our MX records, in other words when our servers manage the emails for it, not some third-party provider. This feature offers you the best degree of security, but it is not applicable if only your website is on our servers while your emails for the domain name are handled somewhere else. Either way, our SPF protection service will keep your emails risk-free from being used for spam or scam purposes.

SPF Protection in Semi-dedicated Servers

If you have a semi-dedicated server account from us, you can protect your email addresses by enabling the SPF protection service for every domain hosted in your account with just a couple of clicks. This is done from the Emails section of the Hepsia Control Panel which comes with the semi-dedicated accounts and even if you have no previous practical experience with such issues, you won't have any kind of troubles to activate the protection. The only things that you will have to do is to pick a domain name from a drop-down list and after that type the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your e-mail addresses will be delivered globally only if they were sent from that server. If your emails are taken care of by our company and not by a third-party supplier, you will also be able to activate an option for e-mail messages to be sent only when the domain name contains our MX records and this would be the safest option.
