SPF, which means Sender Policy Framework, is an e-mail security system, which is is intended to validate if an e-mail message is sent by an authorized server. Employing SPF protection for a domain name will stop the forging of emails created with the domain. In layman's terms: activating this attribute for a domain makes a specific record in the Domain Name System (DNS) which contains the IP addresses of the servers which are allowed to send e-mails from mail boxes using the domain. As soon as this record propagates globally, it will exist on all DNS servers that direct the Internet traffic. Any time a new email message is sent, the first DNS server it goes through tests if it comes from an approved server. If it does, it is forwarded to the destination address, but when it does not originate from a server part of the SPF record for the domain, it is discarded. In this way nobody can mask an e-mail address then make it appear as if you are e-mailing spam. This method is also termed email spoofing.

SPF Protection in Shared Hosting

If you host your domains in a shared hosting account on our end and we handle the email addresses for them, you will be able to activate SPF protection for all of them with a few clicks inside your Hepsia Control Panel. This service is available in a section of its own where you'll be able to view which domain names are already protected. For the ones which aren't, you can activate 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 mailboxes, the IPv4 and IPv6 addresses of these servers, and even to set a rule that email messages can be sent only if your domain names have our MX records. The last solution is the most secure one, but you can use it when we manage the emails for your domains and you are not using a different email service provider. The newly generated records will be activated within a day and nobody will be able to forge the FROM field in an email with your email addresses.
