SPF, which is short for Sender Policy Framework, is an email security system, that is used to verify whether an e-mail message was sent by an official server. Employing SPF protection for a particular domain will stop the counterfeiting of email addresses created with the domain. In layman's terms: enabling this attribute for a domain makes a special record in the Domain Name System (DNS) that contains the IP of the servers which are allowed to send email messages from mail boxes using the domain. As soon as this record propagates globally, it exists on all the DNS servers that route the Internet traffic. Whenever some email message is sent, the initial DNS server it uses verifies if it comes from an accredited server. In the event it does, it's forwarded to the destination address, however if it does not come from a server part of the SPF record for the particular domain, it is discarded. Thus nobody can mask an e-mail address then make it appear as if you're distributing spam messages. This technique is also identified as email spoofing.

SPF Protection in Cloud Website Hosting

If you host your domain names in a cloud website hosting account with us and we handle the emails for them, you'll be able to activate SPF protection for any of them with a couple of clicks inside your Hepsia Control Panel. This service is accessible in a section of its own where you'll be able to see which domain names are already secured. For those which aren't, you can enable the SPF protection service and configure numerous things in the process - 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 even to create a rule that email messages can be sent only if your domain names have our MX records. The last option is the most secure one, and it can be used when we handle the e-mails for your domain names and you are not using another email provider. The newly created records will propagate within 1 day and nobody will be able to forge the FROM field in an email with your addresses.
