SPF, which is short for Sender Policy Framework, is an email security system, that is designed to confirm whether an email message is sent by a licensed server. Using SPF protection for a particular domain will prevent the forging of email addresses generated with the domain. In layman's terms: activating this feature for a domain makes a particular record in the Domain Name System (DNS) containing the IP addresses of the servers that are permitted to send e-mail messages from mailboxes using the domain. Once this record propagates worldwide, it exists on all DNS servers that route the Internet traffic. Whenever an email message is sent, the initial DNS server it goes through tests whether it comes from an approved server. In the event it does, it is forwarded to the destination address, however when it doesn't come from a server listed in the SPF record for the particular domain, it is discarded. In this way nobody can mask an email address and make it look as if you are e-mailing spam messages. This method is also identified as email spoofing.

SPF Protection in Shared Website Hosting

You are able to enable the SPF protection option for your domain names with a few clicks in the Hepsia Control Panel, which is included in all of our shared website hosting. This is performed from the section with the same name and you're able to allow the protection for any domain name hosted on our modern cloud platform. Using a really simple interface, all you will have to submit is the hostname of the mail server that will be authorized to send out messages from your emails and its IPv4 or IPv6 address. Last, but not least, you can add several servers as well, when needed. In case your email addresses are managed by us, you can also use an even more secure option by placing a limit that e-mail messages can be sent only when your domain names feature our MX records. This option cannot be used in case your site is here, and the email addresses are with a third-party service provider. Either way, the SPF protection solution can vastly enhance your web protection and stop others from spoofing your email addresses.
