SPF, which means Sender Policy Framework, is an e-mail security system, that is employed to verify whether an e-mail message was sent by an official server. Employing SPF protection for a domain name will stop the forging of email addresses generated with the domain. In simple words: enabling this attribute for a domain name generates a particular record in the Domain Name System (DNS) containing the IP addresses of the servers which are allowed to send e-mail messages from mail boxes using the domain. When this record propagates worldwide, it will exist on all the DNS servers that route the Internet traffic. Every time some email message is sent, the initial DNS server it uses tests if it comes from an authorized server. If it does, it is forwarded to the destination address, but when it does not come from a server part of the SPF record for the domain, it's discarded. Thus nobody will be able to mask an e-mail address to make it appear as if you are sending spam messages. This method is also known as email spoofing.

SPF Protection in Hosting

When 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 them with several clicks inside your Hepsia Control Panel. The service is accessible in a separate section where you're able to view which domain names are currently secured. For the ones that aren't, you can activate the SPF protection service and set up a lot of things at the same time - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, and even to set a rule that messages can be sent only when your domain names include our MX records. The last mentioned choice is the most secure one, but it can be used in the event that we take care of the e-mails for your domains and you are not using a different e-mail supplier. The newly created records will be activated within a day and nobody will be able to forge the FROM field in an email with your e-mail addresses.
