SPF, which is an acronym for Sender Policy Framework, is an email security system, that is employed to confirm whether an email message was sent by a certified server. Employing SPF protection for a particular domain name will stop the counterfeiting 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) that contains the IP addresses of the servers that are allowed to send e-mails from mail boxes using the domain. As soon as this record propagates worldwide, it will exist on all of the DNS servers that route the Internet traffic. Whenever a new e-mail message is sent, the first DNS server it goes through tests whether it comes from an authorized server. In the event it does, it's sent to the destination address, but if it doesn't come from a server listed in the SPF record for the particular domain, it is rejected. Thus nobody will mask an e-mail address to make it appear as if you are distributing spam. This method is also referred to as email spoofing.

SPF Protection in Shared Hosting

If you host your domain names in a shared hosting account with us and we handle the emails for them, you are able to enable SPF protection for them with a few clicks in your Hepsia Control Panel. This service is available in a separate section where you are able to view which domain names are already secured. For the ones that are not, you can enable the SPF protection option and configure a variety of things during this process - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of these servers, as well as to create a rule that emails can be sent only if your domains include our MX records. The last option is the most secure one, but it can be used when we manage the email addresses for your domain names and do not use some other e-mail supplier. The newly created records will be activated within 24 hours and nobody will be able to forge the FROM field in a message by using your email addresses.
