SPF, which is short for Sender Policy Framework, is an email security system, that is used to validate if an e-mail message is sent by an authorized server. Using SPF protection for a given domain name will prevent the faking of emails created with the domain. In layman's terms: enabling this attribute for a domain generates a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers which are allowed to send email messages from mail boxes under the domain. Once this record propagates globally, it will exist on all the DNS servers that direct the Internet traffic. When a new email message is sent, the initial DNS server it goes through verifies whether it originates from an accredited server. When 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 is discarded. In this way nobody will mask an email address and make it appear as if you are distributing spam. This technique is also identified as email spoofing.

SPF Protection in Hosting

You are able to enable the SPF protection option for your domain names with just a couple of clicks inside the Hepsia Control Panel, which comes with all our Linux hosting packages. This is done via the section bearing the very same name and you'll be able to set up the protection for each and every domain hosted on our leading-edge cloud platform. Using a very user-friendly interface, all you will need to enter is the hostname of the mail server that will be accredited to send messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you can include several servers too, if needed. If your e-mail addresses are managed by us, you may also take advantage of an even more secure option by putting a limit that email messages can be sent only if your domain names feature our MX records. This alternative cannot be applied if your website is hosted with us, and the e-mail addresses are with some third-party supplier. In either case, the SPF protection option will strongly increase your online security and prevent others from spoofing your e-mail addresses.
