SPF, which is an acronym for Sender Policy Framework, is an e-mail security system, that is is intended to confirm if an e-mail message was sent by a certified server. Using SPF protection for a domain will stop the faking of email addresses created with the domain. In layman's terms: activating this feature for a domain name creates a specific record in the Domain Name System (DNS) which includes the IP of the servers that are allowed to send emails from mail boxes using the domain. When this record propagates globally, it will exist on all the DNS servers that direct the Internet traffic. Any time a new e-mail message is sent, the initial DNS server it goes through tests whether it comes from an approved server. If it does, it is sent to the destination address, yet when it doesn't originate from a server indexed in the SPF record for the domain, it is discarded. Thus nobody will mask an email address then make it look as if you're e-mailing spam messages. This technique is also referred to as email spoofing.

SPF Protection in Cloud Website Hosting

You're able to activate the SPF protection option for your domains with just a couple of clicks from the Hepsia Control Panel, which comes with our Linux cloud website hosting. This is performed via the section with an identical name and you can allow the protection for each and every domain name on our cutting-edge cloud platform. Using a very intuitive interface, all you need to enter is the hostname of the mail server which will be authorized to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Last, but not least, you are able to include several servers too, if needed. When your emails are handled on our end, you can also employ an even more secure option by putting a restriction that messages can be sent only when your domain names have our MX records. This option cannot be used when your site is hosted with us, and your emails are with some third-party service provider. Either way, the SPF protection option will significantly improve your web safety and prevent others from forging your e-mail addresses.
