SPF, which stands for Sender Policy Framework, is an email safety system, which is designed to validate whether an email message is sent by a licensed server. Using SPF protection for a particular domain name will stop the counterfeiting of emails generated with the domain. In layman's terms: enabling this feature for a domain makes a particular record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send e-mails from mail boxes under the domain. As soon as this record propagates worldwide, it will exist on all DNS servers that direct the Internet traffic. Every time some email message is sent, the first DNS server it uses tests if it originates from an accredited server. When it does, it is sent to the destination address, however when it doesn't come from a server listed in the SPF record for the domain, it's rejected. In this way nobody will be able to mask an e-mail address to make it appear as if you're distributing spam messages. This approach is also known as email spoofing.

This carried out from the section bearing an identical name and you can enable the protection for any domain hosted on our outstanding cloud hosting platform. Using a really convenient interface, all you need to enter is the hostname of the mail server that will be authorized to send messages from your emails and its IPv4 or IPv6 address. Of course, you are able to include several servers as well, if needed. If your e-mail addresses are managed on our end, you can also employ a more secure option by setting a restriction that emails can be sent only if your domain names feature our MX records. This alternative can't be used in case your site is hosted here, and your e-mails are with a third-party provider. In either case, the SPF protection option can significantly enhance your web security and stop other people from forging your e-mail addresses.
