SPF, which stands for Sender Policy Framework, is an email protection system, which is used to verify whether an email message is sent by an official server. Employing SPF protection for a domain will prevent the forging of email addresses generated with the domain. In layman's terms: enabling this feature for a domain creates a specific record in the Domain Name System (DNS) containing the IP of the servers which are permitted to send e-mails from mailboxes under the domain. The moment this record propagates globally, it exists on all the DNS servers that direct the Internet traffic. Whenever an email message is sent, the initial DNS server it goes through verifies whether it originates from an approved server. In the event it does, it is forwarded to the destination address, yet if it does not originate from a server listed in the SPF record for the domain, it's discarded. In this way nobody can mask an email address then make it appear as if you're sending spam messages. This approach is also known as email spoofing.
SPF Protection in Website Hosting
If you host your domains in a website hosting account on our end and we manage the email addresses for them, you are able to enable SPF protection for them with a couple of clicks inside your Hepsia Control Panel. The service is accessible in a section of its own where you're able to see which domains are currently protected. For the ones which aren't, you'll be able to activate the SPF protection service and configure a number of things at the same time - the hostnames of the mail servers that are allowed to send messages from your addresses, the IPv4 and IPv6 addresses of these servers, and to create a rule that messages can be sent only if your domains use our MX records. The last mentioned option is the most secure one, and you can use it in the event that we take care of the e-mails for your domain names and do not use some other email service provider. The new records will propagate within a day and nobody will be able to forge the FROM field in an email with your e-mail addresses.
SPF Protection in Semi-dedicated Servers
When you host your domain names in a semi-dedicated server account with our company, you'll be able to use the SPF protection feature as part of the conventional collection of services that you will receive using this type of website hosting. Starting the protection will require just a couple of simple steps in the Hepsia Control Panel, therefore even when you have never employed such a function before, you won't have any type of troubles. Through a very intuitive interface, you will simply need to input the info of the mail server which will be authorized to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the recently made record propagates, no one will be able to forge any email for that particular domain and send e-mail messages from a server other than the one you've entered. This doesn't necessarily have to be our mail server, but when we handle your emails, you'll be able to allow one more level of protection by picking an option that email messages can be send out from addresses @your-domain.com only in case the domain uses our MX records. Our technical support staff can help you 24/7 if you have any questions regarding this service.
