SPF, which stands for Sender Policy Framework, is an e-mail protection system, that is designed to confirm if an email message is sent by a certified server. Using SPF protection for a particular domain name will stop the counterfeiting of email addresses made with the domain. In simple words: enabling this attribute for a domain makes a special record in the Domain Name System (DNS) containing the IP addresses of the servers that are permitted to send e-mails from mail boxes using the domain. Once this record propagates worldwide, it exists on all DNS servers that route the Internet traffic. Any time an email message is sent, the initial DNS server it uses tests if it originates from an approved server. When it does, it is sent to the destination address, yet if it does not originate from a server part of the SPF record for the domain, it is rejected. Thus nobody will be able to mask an email address then make it look as if you're distributing spam. This approach is also called email spoofing.
SPF Protection in Shared Hosting
SPF protection can be activated for every domain hosted in a shared hosting account on our cloud platform with just a few clicks. The option is accessible in the Emails section of our modern Hepsia Control Panel and all it takes to activate it is to select one of your domain names from a drop-down list and enter the hostnames plus the IPv4 or IPv6 addresses of the e-mail servers that will be permitted to send email messages from your emails. As an added option you can even restrict the e-mails to be sent from your domain name only if it includes our MX records, i.e. if our servers handle the email addresses for it, not some third-party supplier. This option gives you the highest level of security, but it is not applicable in case only your site is on our servers while your email addresses for the domain are managed in a different place. Either way, our SPF protection service will keep your emails secure from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Servers
When you host your domains in a semi-dedicated server account from us, you will be able to use the SPF protection feature as part of the regular set of services that you will get using this kind of hosting. Starting the protection requires only several simple steps in the Hepsia Control Panel, thus even when you have never used such a function before, you will not have any type of troubles. Using an exceptionally user-friendly interface, you will simply need to enter the info of the mail server which will be authorized to send out messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the recently generated record propagates, nobody will be able to fake any email for that particular domain and send out emails from a server different from the one you have typed in. This doesn't necessarily have to be our mail server, however when we take care of your email messages, you can allow one more level of security by picking an option that e-mail messages can be send from addresses @your-domain.com only in case the domain employs our MX records. Our technical support staff will be able to help you 24/7 if you have any kind of questions about this service.
