Sender Policy Framework, or SPF, is a validation system, that is employed to stop the so-called email spoofing where an e-mail message is sent from one email, but to appear as being sent from another one, frequently with the idea to scam the recipient in some way. If SPF protection is enabled for a domain name, a specific record is created for it in the Domain Name System and all the DNS servers globally receive it. The record contains all the email servers that are permitted to send authentic messages from an address under 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 sent to the target destination. In case, however, the sending server is not included in the SPF record for the specified domain, the message will not be sent and it'll be removed. Whenever you use this service, it will prevent third parties from sending spam that look as if they have been sent from you.

SPF Protection in Shared Website Hosting

When you host your domain names in a shared website hosting account with us and we manage the e-mail addresses for them, you'll be able to activate SPF protection for all of them with a few clicks in your Hepsia Control Panel. The service is accessible in a section of its own where you are able to see which domain names are already secured. For those that are not, you can enable the SPF protection solution and set up a variety of things at the same time - the hostnames of the mail servers that are permitted to send messages from your email addresses, the IPv4 and IPv6 addresses of the servers, and even to set a rule that 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 take care of the email addresses for your domains and you're not using some other e-mail supplier. The new records will propagate within one day and nobody will be able to fake the FROM field in an e-mail using your email addresses.
