SPF, which stands for Sender Policy Framework, is an e-mail security system, which is employed to verify whether an e-mail message was sent by an official server. Employing SPF protection for a given domain will stop the counterfeiting of email addresses created with the domain. In layman's terms: enabling this feature for a domain creates a particular record in the Domain Name System (DNS) containing the IP addresses of the servers that are allowed to send e-mails from mail boxes under the domain. As soon as this record propagates worldwide, it exists on all the DNS servers that direct the Internet traffic. When a new email message is sent, the initial DNS server it goes through checks if it comes from an authorized server. When it does, it's sent to the destination address, yet if it doesn't originate from a server listed in the SPF record for the domain, it is rejected. Thus nobody will mask an e-mail address then make it appear as if you are distributing spam. This approach is also referred to as email spoofing.

SPF Protection in Cloud Website Hosting

When you host your domains in a cloud website hosting account with us and we manage the e-mail addresses for them, you will be able to activate SPF protection for all of them with a few clicks in your Hepsia Control Panel. This service is available in a section of its own where you're able to view which domain names are already protected. For those that aren't, you will be able to activate the SPF protection option and set up a variety of things at the same time - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of these servers, and to set a rule that messages can be sent only when your domain names have our MX records. The last solution is the most secure one, and you can use it if we manage the e-mails for your domain names and do not use a different e-mail provider. The new records will be activated within 24 hours and nobody will be able to fake the FROM field in an e-mail using your email addresses.

SPF Protection in Semi-dedicated Hosting

When you host your domains in a semi-dedicated server account from us, you are able to use the SPF protection feature as part of the standard collection of services that you will have with this kind of website hosting. Activating the protection requires only several simple steps in the Hepsia Control Panel, thus even if you have never used this type of function before, you will not have any kind of issues. Employing an exceptionally time and effort saving interface, you'll only need to type in the details of the mail server that will be authorized to send out messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the newly created record propagates, no one will be able to counterfeit any email for that particular domain name and send out e-mail messages from a server different from the one you've entered. This doesn't specifically have to be our mail server, but in case we handle your emails, you can activate one more level of protection by picking an option that emails can be send out from addresses @your-domain.com only in the event that the domain uses our MX records. Our tech support staff can assist you 24/7 in case you have any questions regarding this service.
