SPF, which stands for Sender Policy Framework, is an email safety system, that is is intended to validate whether an e-mail message is sent by an official server. Employing SPF protection for a particular domain name will stop the forging of email addresses made with the domain. In layman's terms: enabling this function for a domain name generates a particular record in the Domain Name System (DNS) which includes the IP addresses of the servers that are allowed to send e-mails from mailboxes under the domain. As soon as this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. When some e-mail message is sent, the initial DNS server it uses tests if it originates from an official server. In the event it does, it is forwarded to the destination address, however if it does not come from a server indexed in the SPF record for the particular domain, it's rejected. In this way nobody will be able to mask an email address and make it appear as if you are distributing spam. This approach is also referred to as email spoofing.
SPF Protection in Cloud Web Hosting
If you host your domains in a cloud web hosting account with us and we manage the email addresses for them, you are able to activate SPF protection for any of them with several clicks inside your Hepsia Control Panel. This service is available in a separate section where you can see which domains are currently protected. For those that are not, you can enable the SPF protection solution and manage various things at the same time - the hostnames of the mail servers that are allowed 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 domains use our MX records. The aforementioned option is the most secure one, but you can use it when we take care of the e-mail addresses for your domain names and do not use some other e-mail provider. The newly generated records will propagate within 1 day and nobody will be able to forge the FROM field in an email by using your email addresses.
