SPF, which is short for Sender Policy Framework, is an e-mail protection system, that is employed to confirm whether an email message is sent by an official server. Employing SPF protection for a given domain name will stop the forging of emails generated with the domain. In layman's terms: activating this function for a domain makes a special record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send e-mail messages from mail boxes using the domain. When this record propagates worldwide, it exists on all the DNS servers that route the Internet traffic. Any time a new e-mail message is sent, the initial DNS server it goes through tests if it originates from an official server. If it does, it is sent to the destination address, however if it doesn't come from a server listed in the SPF record for the domain, it's discarded. Thus nobody can mask an e-mail address and make it appear as if you're distributing spam. This technique is also identified as email spoofing.

SPF Protection in Cloud Website Hosting

You'll be able to activate the SPF protection service for your domain names with a couple of clicks inside the Hepsia Control Panel, which is included in all our cloud website hosting plans. This is performed from the section bearing the very same name and you can allow the protection for each domain on our leading-edge cloud platform. Using a really simple interface, all you will need to type in is the hostname of the mail server that will be authorized to send messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you'll be able to include several servers too, when needed. In case your emails are handled by us, you can also take advantage of an even more secure option by putting a restriction that email messages can be sent only when your domains include our MX records. This solution cannot be applied if your website is hosted here, but your e-mails are with a third-party supplier. Either way, the SPF protection solution can strongly enhance your web security and stop other people from spoofing your e-mail addresses.
