SPF, which is an acronym for Sender Policy Framework, is an e-mail safety system, that is used to validate whether an e-mail message is sent by a licensed server. Employing SPF protection for a given domain will prevent the counterfeiting of emails created with the domain. In layman's terms: enabling this function for a domain generates a special record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send e-mails from mailboxes under the domain. The moment this record propagates globally, it will exist on all of the DNS servers that route the Internet traffic. When an e-mail message is sent, the initial DNS server it uses tests if it originates from an official server. When it does, it is forwarded to the destination address, however if it does not originate from a server part of the SPF record for the particular domain, it is rejected. Thus nobody will mask an e-mail address and make it appear as if you are e-mailing spam messages. This technique is also known as email spoofing.

SPF Protection in Web Hosting

When you host your domains in a web hosting account on our end and we manage the e-mails for them, you are able to activate SPF protection for all of them with a couple of clicks in your Hepsia Control Panel. This service is accessible in its own section where you're able to see which domains are already protected. For the ones that are not, you will be able to enable the SPF protection service and manage numerous things at the same time - the hostnames of the mail servers that are allowed to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, and to create a rule that email messages can be sent only if your domains have our MX records. The last solution is the most secure one, but it can be used if we take care of the email addresses for your domain names and do not use some other e-mail service provider. The newly generated records will be activated within 24 hours and nobody will be able to forge the FROM field in an email by using your addresses.
