SPF, which means Sender Policy Framework, is an e-mail security system, that is designed to confirm if an e-mail message is sent by a certified server. Using SPF protection for a domain will prevent the counterfeiting of emails made with the domain. In layman's terms: enabling this function for a domain generates a special record in the Domain Name System (DNS) containing the IP of the servers that are allowed to send e-mails from mail boxes under the domain. As soon as this record propagates globally, it will exist on all DNS servers that direct the Internet traffic. Whenever an e-mail message is sent, the initial DNS server it goes through verifies whether it comes from an accredited server. When it does, it's sent to the destination address, but when it doesn't come from a server listed in the SPF record for the domain, it's discarded. In this way nobody can mask an email address and make it appear as if you're e-mailing spam. This approach is also identified as email spoofing.

SPF Protection in Cloud Hosting

You are able to activate the SPF protection option for your domains with just a couple of clicks in the Hepsia Control Panel, which is provided with all of our Linux cloud hosting. This is performed via the section bearing the very same name and you can enable the protection for any domain name on our state-of-the-art cloud hosting platform. Using a really convenient interface, all you will have to type in is the hostname of the mail server that will be approved to send messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you can add several servers too, if needed. When your email addresses are managed on our end, you may also employ an even more risk-free option by placing a limit that email messages can be sent only when your domain names include our MX records. This alternative can't be used when your website is hosted here, and your emails are with a third-party supplier. Either way, the SPF protection solution will greatly enhance your online safety and prevent others from forging your email addresses.
