Sender Policy Framework, or SPF, is a validation system, that is employed to prevent the so-called email spoofing where an email message is sent from one e-mail address, but to appear as being sent from a different, ordinarily with the purpose to fraud the recipient for some reason. If SPF protection is activated for a domain name, a specific record is created for it in the Domain Name System and all of the DNS servers around the world have it. The record features all the mail servers that are permitted to send valid messages from an email address under the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and if the sending server is authorized, the message is sent to the targeted destination. When, however, the sending server doesn't exist in the SPF record for the specified domain, the email message won't be sent and it'll be discarded. Whenever you use this service, it'll stop third parties from sending spam messages that seem to have been sent by you.

SPF Protection in Shared Hosting

SPF protection can be activated for each domain name hosted in a shared hosting account on our cloud platform with only a few mouse-clicks. The feature is available in the Emails section of our amazing Hepsia Control Panel and all it takes to activate it is to select one of your domains from the drop-down list and then enter the hostnames and the IPv4 or IPv6 addresses of the mail servers that will be permitted to send messages from your emails. As an added option you may also restrict the messages to be sent from your domain only if it has our MX records, in other words when our servers handle the email addresses for it, not a third-party supplier. This solution provides you with the highest degree of safety, but it's not applicable when only your site is on our servers while the e-mail addresses for the domain are taken care of somewhere else. Regardless, the SPF protection service will keep your emails secure from being used for spam or scam purposes.

SPF Protection in Semi-dedicated Hosting

If you host your domain names in a semi-dedicated server account from us, you will be able to take advantage of the SPF protection feature as a part of the conventional group of services that you'll receive with this kind of website hosting. Activating the protection involves just a couple of simple steps in the Hepsia Control Panel, so even in the event that you have never employed this type of feature before, you won't have any troubles. Employing a really user-friendly interface, you will just need to type in the info of the mail server that will be certified to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the newly created record propagates, nobody will be able to forge any e-mail address for that particular domain name and send out e-mail messages from a server different from the one you've typed in. This does not specifically have to be our mail server, yet when we manage your email messages, you will be able to allow an additional level of security by picking an option that e-mails can be send from addresses @your-domain.com only in case the domain uses our MX records. Our technical support team can help you 24/7 if you have any kind of questions related to this service.
