SPF, which means Sender Policy Framework, is an e-mail security system, which is designed to validate if an e-mail message is sent by an official server. Using SPF protection for a given domain name will stop the faking of email addresses made with the domain. In simple words: activating this feature for a domain name makes a particular record in the Domain Name System (DNS) containing the IP addresses of the servers that are allowed to send email messages from mailboxes under the domain. The moment this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. When an e-mail message is sent, the initial DNS server it goes through verifies whether it comes from an approved server. If it does, it is forwarded to the destination address, yet when it does not come from a server indexed in the SPF record for the particular domain, it is discarded. In this way nobody can mask an e-mail address to make it look as if you're distributing spam. This approach is also identified as email spoofing.

SPF Protection in Web Hosting

You can enable the SPF protection option for your domains with just a couple of clicks from the Hepsia Control Panel, which is provided with all our web hosting plans. This is performed from the section bearing an identical name and you can allow the protection for each and every domain name hosted on our advanced cloud hosting platform. Using a very intuitive interface, all you will need to submit is the hostname of the mail server which will be permitted to send messages from your emails and its IPv4 or IPv6 address. Of course, you're able to include several servers as well, if needed. If your email addresses are handled by us, you may also use a more risk-free option by placing a restriction that messages can be sent only when your domains include our MX records. This option cannot be used in case your site is hosted with us, while the emails are with some third-party provider. In either case, the SPF protection option will strongly increase your online protection and prevent others from forging your e-mail addresses.
