SPF, which means Sender Policy Framework, is an email protection system, that is is intended to verify whether an e-mail message was sent by an authorized server. Employing SPF protection for a given domain will prevent the forging of emails generated with the domain. In layman's terms: enabling this function for a domain name creates a special record in the Domain Name System (DNS) which contains the IP of the servers that are permitted to send emails from mail boxes using the domain. When this record propagates globally, it exists on all the DNS servers that route the Internet traffic. Any time a new email message is sent, the initial DNS server it uses checks if it originates from an official server. In the event it does, it is sent to the destination address, but if it does not come from a server listed in the SPF record for the particular domain, it's discarded. Thus nobody will mask an email address and make it appear as if you're distributing spam messages. This approach is also referred to as email spoofing.

SPF Protection in Cloud Website Hosting

If you host your domains in a cloud website hosting account with us and we manage the e-mail addresses for them, you are able to activate SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. This service can be found in a separate section where you'll be able to see which domains are currently secured. For those that are not, you can activate the SPF protection solution and set up a lot of things during the process - 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 if your domains use our MX records. The last mentioned solution is the most secure one, and it can be used in the event that we handle the e-mails for your domains and do not use some other e-mail service provider. The newly generated records will propagate within 1 day and nobody will be able to forge the FROM field in a message by using your e-mail addresses.
