SPF, which stands for Sender Policy Framework, is an e-mail protection system, which is designed to validate if an e-mail message was sent by a certified server. Using SPF protection for a given domain name will stop the forging of email addresses generated with the domain. In layman's terms: activating this attribute for a domain name makes a particular record in the Domain Name System (DNS) containing the IP of the servers that are allowed to send email messages from mailboxes using the domain. Once this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. When a new email message is sent, the initial DNS server it goes through tests whether it comes from an official server. In the event it does, it is forwarded to the destination address, but when it does not originate from a server listed in the SPF record for the particular domain, it is discarded. Thus nobody can mask an email address and make it appear as if you're distributing spam messages. This approach is also identified as email spoofing.

SPF Protection in Hosting

If you host your domain names in a hosting account on our end and we handle the emails for them, you'll be able to activate SPF protection for any of them with a few clicks in your Hepsia Control Panel. This service can be found in a separate section where you will be able to see which domain names are already secured. For the ones which aren't, you'll be able to activate the SPF protection solution and configure a lot of things during this process - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of these servers, as well as to create a rule that emails can be sent only if your domain names include our MX records. The last option is the most secure one, but you can use it in the event that we handle the e-mail addresses for your domains and you're not using another email supplier. The newly created records will propagate within 24 hours and nobody will be able to fake the FROM field in an email by using your e-mail addresses.
