SPF, which means Sender Policy Framework, is an e-mail security system, that is designed to verify if an e-mail message was sent by an authorized server. Employing SPF protection for a domain name will prevent the forging of emails made with the domain. In layman's terms: activating this attribute for a domain name creates a specific record in the Domain Name System (DNS) containing the IP of the servers that are permitted to send emails from mailboxes under the domain. Once this record propagates worldwide, it will exist on all DNS servers that route the Internet traffic. Whenever an email message is sent, the initial DNS server it uses verifies whether it comes from an accredited server. In the event it does, it is sent to the destination address, but when it doesn't originate from a server listed in the SPF record for the particular domain, it is discarded. Thus nobody will mask an email address then make it appear as if you're distributing spam. This technique is also termed 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 e-mail addresses for them, you will be able to activate SPF protection for all of them with a couple of clicks inside your Hepsia Control Panel. The service is available in a section of its own where you're able to view which domain names are already protected. For those that are not, you'll be able to activate the SPF protection service and set up a number of things in the process - the hostnames of the mail servers that are permitted to send messages from your addresses, the IPv4 and IPv6 addresses of these servers, as well as to set a rule that emails can be sent only if your domains use our MX records. The aforementioned solution is the most secure one, but it can be used if we manage the e-mails for your domain names and you're not using some other e-mail provider. The newly created records will propagate within a day and nobody will be able to forge the FROM field in an e-mail by using your email addresses.
