SPF, which means Sender Policy Framework, is an email security system, which is designed to verify if an email message was sent by a licensed server. Using SPF protection for a given domain will prevent the forging of emails generated with the domain. In simple words: enabling this attribute for a domain name makes a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers which are allowed to send emails from mail boxes using the domain. The moment this record propagates globally, it exists on all DNS servers that direct the Internet traffic. Any time a new email message is sent, the first DNS server it uses tests if it comes from an official server. In the event it does, it's sent to the destination address, yet when it does not come from a server indexed in the SPF record for the domain, it is rejected. In this way nobody can mask an e-mail address then make it appear as if you're distributing spam. This technique is also identified as email spoofing.

SPF Protection in Shared Hosting

You can activate the SPF protection option for your domains with just a couple of clicks from the Hepsia Control Panel, which is included with all our shared hosting. This carried out through the section bearing the same name and you are able to set up the protection for each domain name part of our advanced cloud hosting platform. Using a very handy interface, all you need to enter 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 are able to add several servers too, when needed. In case your e-mail addresses are handled on our end, you can also use an even more risk-free option by putting a restriction that e-mail messages can be sent only when your domains include our MX records. This alternative can't be used in case your web site is hosted with us, and your e-mail addresses are with a third-party service provider. In either case, the SPF protection option can tremendously improve your web security and prevent other people from spoofing your email addresses.
