SPF, which means Sender Policy Framework, is an e-mail security system, that is used to confirm if an email message was sent by an authorized server. Employing SPF protection for a domain will stop the forging of emails generated with the domain. In simple words: enabling this function for a domain generates a particular record in the Domain Name System (DNS) which contains the IP of the servers that are permitted to send e-mail messages from mailboxes under the domain. As soon as this record propagates worldwide, it will exist on all the DNS servers that route the Internet traffic. Every time an email message is sent, the initial DNS server it goes through verifies whether it comes from an official server. If it does, it is forwarded to the destination address, but when it doesn't originate from a server indexed in the SPF record for the domain, it is rejected. In this way nobody can mask an e-mail address to make it look as if you are sending spam. This technique is also known as email spoofing.
SPF Protection in Hosting
You'll be able to activate the SPF protection option for your domains with only a few clicks in the Hepsia Control Panel, which is included with our hosting. This is done via the section with an identical name and you are able to enable the protection for each domain name on our hi-tech cloud platform. Using a very time and effort saving interface, all you will have to type in is the hostname of the mail server that will be authorized to send messages from your emails and its IPv4 or IPv6 address. Last, but not least, you are able to include several servers too, when needed. If your e-mails are handled on our end, you may also take advantage of a more secure option by placing a restriction that emails can be sent only if your domains have our MX records. This option cannot be used when your website is hosted here, while the e-mails are with a third-party provider. In either case, the SPF protection option will considerably improve your online safety and stop others from spoofing your email addresses.
