SPF, which stands for Sender Policy Framework, is an email safety system, that is designed to confirm if an email message is sent by a licensed server. Using SPF protection for a domain name will stop the forging of email addresses generated with the domain. In simple words: activating this feature for a domain name generates a specific record in the Domain Name System (DNS) that contains the IP of the servers which are allowed to send emails from mailboxes using the domain. As soon as this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. Every time a new email message is sent, the initial DNS server it uses verifies if it comes from an approved server. In the event it does, it's sent to the destination address, however when it does not originate from a server listed in the SPF record for the domain, it is rejected. In this way nobody can mask an email address then make it look as if you're e-mailing spam. This technique is also called email spoofing.

SPF Protection in Shared Web Hosting

If you host your domain names in a shared web hosting account with us and we manage the emails for them, you'll be able to enable SPF protection for all of them with a few clicks inside your Hepsia Control Panel. The service can be found in a section of its own where you're able to view which domain names are already protected. For those that aren't, you'll be able to activate the SPF protection option and set up a variety of things at the same time - the hostnames of the mail servers that are allowed to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, as well as to set a rule that messages can be sent only when your domain names include our MX records. The last choice is the most secure one, but you can use it when we handle the emails for your domains and you are not using a different e-mail supplier. The newly created records will be activated within 24 hours and nobody will be able to fake the FROM field in an e-mail using your email addresses.
