SPF, which stands for Sender Policy Framework, is an e-mail protection system, that is designed to validate whether an e-mail message was sent by an authorized server. Using SPF protection for a particular domain will stop the counterfeiting of emails generated with the domain. In simple words: enabling this attribute for a domain name makes a specific 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. When this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. When a new e-mail message is sent, the initial DNS server it uses tests whether it comes from an approved server. If it does, it's forwarded to the destination address, yet when it does not come from a server indexed in the SPF record for the domain, it is rejected. Thus nobody will be able to mask an email address then make it appear as if you're e-mailing spam messages. This method is also known as email spoofing.
SPF Protection in Cloud Hosting
If you host your domains in a cloud hosting account with us and we handle the e-mail addresses for them, you will be able to activate SPF protection for them with several clicks in your Hepsia Control Panel. This service is accessible in its own section where you're able to view which domain names are currently protected. For the ones which aren't, you'll be able to enable the SPF protection service and set up numerous things during this process - the hostnames of the mail servers that are allowed to send messages from your addresses, the IPv4 and IPv6 addresses of these servers, and even to create a rule that messages can be sent only if your domains have our MX records. The last solution is the most secure one, but you can use it if we take care of the emails for your domains and you're not using a different e-mail service provider. The newly created records will be activated within one day and nobody will be able to forge the FROM field in a message with your email addresses.
