SPF, which stands for Sender Policy Framework, is an e-mail security system, that is used to confirm whether an e-mail message is sent by an authorized server. Employing SPF protection for a domain will stop the forging of emails created with the domain. In simple words: enabling this attribute for a domain name makes a particular record in the Domain Name System (DNS) which contains the IP of the servers that are permitted to send e-mails from mailboxes under the domain. Once this record propagates worldwide, it exists on all of the DNS servers that route the Internet traffic. Every time an e-mail message is sent, the initial DNS server it uses tests if it originates from an official server. When it does, it is sent to the destination address, yet when it doesn't originate from a server part of the SPF record for the particular domain, it's rejected. Thus nobody will be able to mask an e-mail address to make it look as if you're distributing spam. This technique is also termed email spoofing.

SPF Protection in Website Hosting

You'll be able to activate the SPF protection option for your domains with a few clicks inside the Hepsia Control Panel, which is provided with all our website hosting. This is done via the section with an identical name and you're able to set up the protection for each domain on our leading-edge cloud platform. Using a really intuitive interface, all you will have to enter is the hostname of the mail server which will be approved to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Last, but not least, you're able to include several servers too, if needed. If your e-mails are handled on our end, you can also take advantage of an even more risk-free option by putting a restriction that emails can be sent only when your domains feature our MX records. This option cannot be used if your site is hosted here, while your emails are with a third-party service provider. In either case, the SPF protection option will vastly improve your online safety and prevent others from counterfeiting your email addresses.
