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 e-mail, but to seem as being sent from another one, ordinarily with the purpose to fraud the recipient in some way. If SPF protection is enabled for a domain name, a unique record is created for it in the Domain Name System and all DNS servers around the world receive it. The record includes all e-mail servers that are permitted to send legitimate messages from an email address part of the domain. When a message is sent, the very first DNS server it goes to verifies the SPF record and when the sending server is permitted, the message is sent to the target destination. If, however, the sending server doesn't exist in the SPF record for the specified domain, the message won't be sent and it'll be discarded. When you use this solution, it will stop third parties from sending spam messages which appear to have been sent from you.

SPF Protection in Hosting

You'll be able to activate the SPF protection service for your domains with only a few clicks in the Hepsia Control Panel, which is included in all our hosting plans. This is done via the section with the same name and you can set up the protection for any domain name hosted on our innovative cloud platform. Using a very time and effort saving interface, all you have to type in is the hostname of the mail server which will be authorized to send out messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you can include several servers too, if needed. In case your email addresses are taken care of on our end, you can also use a more risk-free option by placing a restriction that email messages can be sent only when your domains have our MX records. This solution can't be applied when your site is hosted with us, but the e-mails are with some third-party provider. Either way, the SPF protection solution will strongly improve your online security and prevent other people from spoofing your e-mail addresses.

Starting the protection will require only several simple steps inside the Hepsia Control Panel, so even when you haven't used such a function before, you will not have any type of troubles. Employing an exceptionally time and effort saving interface, you'll simply need to input the info of the mail server that will be certified to send messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the newly created record propagates, no one will be able to fake any email address for that particular domain and send messages from a server different from the one you've typed in. This does not necessarily have to be our mail server, however in case we take care of your email messages, you will be able to enable an extra level of protection by selecting an option that emails can be send from addresses @your-domain.com only if the domain uses our MX records.
