Sender Policy Framework, or SPF, is a validation system, that is intended to stop the so-called email spoofing where an email message can be sent from one email address, but to appear as being sent from a different, generally with the objective to fraud the recipient for some reason. When SPF protection is enabled for a domain, a specific record is created for it in the Domain Name System and all of the DNS servers around the world get it. The record includes all of the mail servers that are allowed to send valid messages from an address under the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and if the sending server is permitted, the message is sent to the targeted destination. When, however, the sending server is not present in the SPF record for the particular domain, the email message won't be sent and it'll be removed. In case you use this solution, it will stop third parties from sending spam e-mails that look as if they have been sent by you.

SPF Protection in Web Hosting

When you host your domains in a web hosting account on our end and we manage the e-mail addresses for them, you'll be able to enable SPF protection for all of them with several clicks in your Hepsia Control Panel. The service can be found in a separate section where you are able to see which domains are already protected. For those which aren't, you will be able to activate the SPF protection solution and set up a lot of things during this process - the hostnames of the mail servers that are permitted to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, and to set a rule that emails can be sent only if your domain names include our MX records. The last mentioned choice is the most secure one, and you can use it when we handle the e-mail addresses for your domain names and do not use some other email service provider. The newly created records will be activated within 24 hours and nobody will be able to fake the FROM field in an email using your e-mail addresses.
