SPF, which stands for Sender Policy Framework, is an e-mail security system, that is designed to confirm if an email message is sent by an official server. Using SPF protection for a particular domain name will stop the forging of emails created with the domain. In layman's terms: activating this function for a domain name generates a specific record in the Domain Name System (DNS) which contains the IP addresses of the servers that are permitted to send emails from mailboxes under the domain. As soon as this record propagates globally, it exists on all DNS servers that route the Internet traffic. Any time an e-mail message is sent, the initial DNS server it uses tests if it comes from an accredited server. If it does, it's sent to the destination address, but when it doesn't come from a server indexed in the SPF record for the particular domain, it's rejected. In this way nobody will mask an e-mail address and make it appear as if you are sending spam. This technique is also referred to as email spoofing.

SPF Protection in Hosting

You can activate the SPF protection option for your domain names with only a few clicks from the Hepsia Control Panel, which comes with all of our Linux hosting packages. This is done via the section bearing the very same name and you'll be able to set up the protection for each and every domain name hosted on our cutting-edge cloud hosting platform. Using a very simple interface, all you'll need to type in is the hostname of the mail server that will be permitted to send out messages from your e-mails and its IPv4 or IPv6 address. Of course, you'll be able to include several servers as well, when needed. When your email addresses are handled by us, you can also use an even more risk-free option by setting a restriction that e-mail messages can be sent only when your domains have our MX records. This alternative cannot be applied when your site is hosted here, and the e-mails are with a third-party supplier. Either way, the SPF protection option can greatly enhance your online security and prevent others from counterfeiting your email addresses.
