SPF, which is short for Sender Policy Framework, is an email security system, that is used to verify whether an e-mail message was sent by a licensed server. Employing SPF protection for a domain name will stop the counterfeiting of emails created with the domain. In simple words: enabling this function for a domain name creates a particular record in the Domain Name System (DNS) which contains the IP addresses of the servers that are allowed to send emails from mail boxes under the domain. When this record propagates worldwide, it will exist on all DNS servers that direct the Internet traffic. When an email message is sent, the initial DNS server it goes through checks if it originates from an approved server. If it does, it's forwarded to the destination address, however if it does not come from a server indexed in the SPF record for the domain, it's discarded. Thus nobody can mask an email address then make it appear as if you are sending spam messages. This approach is also known as email spoofing.

SPF Protection in Shared Website Hosting

If you host your domain names in a shared website hosting account with us and we manage the email addresses for them, you'll be able to enable SPF protection for all of them with a couple of clicks in your Hepsia Control Panel. The service is accessible in a section of its own where you're able to see which domains are already secured. For those that are not, you can activate the SPF protection option and manage various things during this process - the hostnames of the mail servers that are permitted to send messages from your emails, the IPv4 and IPv6 addresses of the servers, as well as to set a rule that email messages can be sent only when your domains include our MX records. The last option is the most secure one, and you can use it in the event that we manage the e-mail addresses for your domains and do not use some other e-mail service provider. The newly created records will be activated within 1 day and nobody will be able to forge the FROM field in an email with your e-mail addresses.
