SPF, which is short for Sender Policy Framework, is an e-mail safety system, that is designed to validate whether an e-mail message was sent by a certified server. Employing SPF protection for a given domain name will prevent the counterfeiting of emails created with the domain. In layman's terms: activating this feature for a domain generates a special record in the Domain Name System (DNS) which includes 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 of the DNS servers that direct the Internet traffic. Whenever some email message is sent, the initial DNS server it goes through tests if it originates from an accredited server. In the event it does, it is forwarded to the destination address, but when it doesn't originate from a server indexed in the SPF record for the particular domain, it's rejected. In this way nobody will mask an e-mail address and make it appear as if you are e-mailing spam. This approach is also referred to as email spoofing.

SPF Protection in Cloud Hosting

When you host your domain names in a cloud hosting account with us and we manage the emails for them, you will be able to enable SPF protection for them with a couple of clicks in your Hepsia Control Panel. This service is accessible in a separate section where you can see which domains are already secured. For those that aren't, you'll be able to activate the SPF protection solution and set up a number of things in the process - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of the servers, and to create a rule that email messages can be sent only when your domain names have our MX records. The aforementioned solution is the most secure one, and it can be used when we handle the e-mail addresses for your domains and you are not using another email supplier. The newly created records will be activated within 24 hours and nobody will be able to forge the FROM field in an e-mail using your e-mail addresses.
