SPF, which stands for Sender Policy Framework, is an e-mail safety system, that is employed to confirm if an email message was sent by a certified server. Employing SPF protection for a domain will stop the counterfeiting of email addresses made with the domain. In simple words: enabling this feature for a domain makes a special record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send emails from mailboxes using the domain. When this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. When a new email message is sent, the first DNS server it goes through checks if it originates from an official server. In the event it does, it is forwarded to the destination address, however if it doesn't originate from a server part of the SPF record for the particular domain, it's rejected. Thus nobody will be able to mask an email address to make it look as if you're e-mailing spam messages. This approach is also referred to as email spoofing.
SPF Protection in Web Hosting
When you host your domain names in a web hosting account on our end and we handle the e-mail addresses for them, you'll be able to enable SPF protection for them with a couple of clicks in your Hepsia Control Panel. The service can be found in a separate section where you will be able to see which domains are currently secured. For the ones which aren't, you can activate the SPF protection service and manage a number of things during the process - the hostnames of the mail servers that are permitted to send messages from your emails, the IPv4 and IPv6 addresses of these servers, and to set a rule that email messages can be sent only when your domains include our MX records. The last option is the most secure one, and it can be used in the event that we handle the emails for your domain names and you're not using a different email supplier. The newly created records will be activated within 24 hours and nobody will be able to fake the FROM field in an email with your addresses.
