SPF, which stands for Sender Policy Framework, is an e-mail safety system, that is designed to verify if an e-mail message is sent by an official server. Using SPF protection for a given domain name will prevent the faking of emails generated with the domain. In layman's terms: enabling this attribute for a domain name generates a particular record in the Domain Name System (DNS) that contains the IP of the servers that are permitted to send e-mails from mailboxes under the domain. When this record propagates worldwide, it exists on all DNS servers that direct the Internet traffic. Any time some email message is sent, the initial DNS server it uses verifies whether it comes from an authorized server. When it does, it is sent to the destination address, but if it does not come from a server part of the SPF record for the domain, it is discarded. Thus nobody will be able to mask an e-mail address to make it appear as if you are distributing spam messages. This approach is also known as email spoofing.

SPF Protection in Hosting

If you host your domain names in a hosting account on our end and we handle the email addresses for them, you'll be able to activate SPF protection for all of them with a few clicks inside your Hepsia Control Panel. This service is accessible in its own section where you'll be able to see which domains are already protected. For the ones that aren't, you will be able to activate the SPF protection option and set up various things at the same time - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, and even to set a rule that email messages can be sent only if your domains include our MX records. The aforementioned choice is the most secure one, and you can use it when we take care of the email addresses for your domains and you are not using a different email service provider. The newly generated records will propagate within one day and nobody will be able to fake the FROM field in an e-mail by using your e-mail addresses.
