Sender Policy Framework, or SPF, is a validation system, that is used to prevent the so-called e-mail spoofing where an e-mail message can be sent from one email address, but to appear as being sent from a different one, usually with the purpose to fraud the recipient someway. When SPF protection is activated for a domain name, a specific record is created for it in the Domain Name System and all DNS servers worldwide receive it. The record features all e-mail servers that are allowed to send legitimate messages from an address part of the domain. When an e-mail is sent, the very first DNS server it goes to verifies the SPF record and if its sending server is authorized, the message is forwarded to the targeted receiver. When, however, the sending server is not contained in the SPF record for the given domain, the e-mail message will not be submitted and it'll be removed. When you use this service, it will prevent third parties from sending spam emails that appear to have been sent from you.

SPF Protection in Shared Website Hosting

If you host your domain names in a shared website hosting account on our end and we handle the emails for them, you will be able to activate SPF protection for any of them with a few clicks inside your Hepsia Control Panel. This service is available in a separate section 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 service and manage a variety of things during the process - the hostnames of the mail servers that are allowed to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of these servers, and to set a rule that messages can be sent only when your domain names have our MX records. The aforementioned choice is the most secure one, but you can use it if we handle the emails for your domains and do not use some other email service provider. The newly generated records will propagate within 24 hours and nobody will be able to fake the FROM field in an email by using your email addresses.
