SPF, which is an acronym for Sender Policy Framework, is an email security system, which is is intended to validate whether an e-mail message is sent by an authorized server. Employing SPF protection for a given domain name will stop the forging of emails generated with the domain. In simple words: enabling this attribute for a domain creates a particular record in the Domain Name System (DNS) which contains the IP addresses of the servers which are permitted to send e-mails from mail boxes using the domain. The moment this record propagates worldwide, it will exist on all DNS servers that direct the Internet traffic. Whenever an e-mail message is sent, the first DNS server it goes through verifies whether it comes from an authorized server. In the event it does, it is sent to the destination address, however if it does not come from a server listed in the SPF record for the domain, it is discarded. In this way nobody can mask an e-mail address then make it look as if you're e-mailing spam. This technique is also known as email spoofing.

SPF Protection in Cloud Hosting

You're able to enable the SPF protection option for your domains with just a few clicks from the Hepsia Control Panel, which is included with our cloud hosting plans. This is done via the section with the very same name and you are able to allow the protection for each domain name on our outstanding cloud hosting platform. Using a really intuitive interface, all you have to enter is the hostname of the mail server which will be approved to send out messages from your emails and its IPv4 or IPv6 address. Of course, it is possible to include several servers too, when needed. In case your e-mails are handled by us, you may also use an even more risk-free option by placing a limit that e-mails can be sent only if your domains have our MX records. This option cannot be used in case your website is hosted with us, and your e-mail addresses are with some third-party service provider. Either way, the SPF protection option will vastly increase your online security and prevent other people from spoofing your e-mail addresses.
