SPF, which is an acronym for Sender Policy Framework, is an email protection system, which is is intended to verify if an e-mail message was sent by an authorized server. Employing SPF protection for a particular domain will stop the counterfeiting of emails made with the domain. In layman's terms: enabling this feature for a domain name generates a special record in the Domain Name System (DNS) containing the IP addresses of the servers that are allowed to send e-mail messages from mailboxes under the domain. Once this record propagates worldwide, it will exist on all DNS servers that direct the Internet traffic. Every time an email message is sent, the initial DNS server it goes through tests if it comes from an authorized server. In the event it does, it's sent to the destination address, yet when it doesn't originate from a server indexed in the SPF record for the particular domain, it is rejected. In this way nobody will mask an email address and make it look as if you are e-mailing spam. This technique is also termed email spoofing.

SPF Protection in Web Hosting

You can enable the SPF protection option for your domain names with only a few clicks in the Hepsia Control Panel, which is included in all of our Linux web hosting. This is performed through the section bearing the same name and you can set up the protection for each domain part of our modern cloud platform. Using a very simple interface, all you'll need to type in is the hostname of the mail server that will be permitted to send messages from your email addresses and its IPv4 or IPv6 address. Of course, you can add several servers as well, if needed. If your e-mail addresses are taken care of on our end, you can also use a more secure option by placing a limit that emails can be sent only when your domains have our MX records. This solution can't be applied in case your site is hosted here, and your e-mail addresses are with some third-party supplier. In either case, the SPF protection solution will strongly increase your online security and prevent others from counterfeiting your email addresses.

SPF Protection in Semi-dedicated Hosting

The SPF protection feature comes with all Linux semi-dedicated hosting, so in case you host your domain names in an account on our cloud web hosting platform, you can use this service with ease for all your domains. The Hepsia Control Panel, which is included with the semi-dedicated accounts, offers a quite intuitive interface, so you will not have to be tech-savvy to protected your email addresses. You'll simply need to type the hostname and the IP address of each mail server that you'd like to be certified to send out emails from your addresses and shortly after that the updated record will be active for the domain that you have selected. As a further option, we also give you the ability to limit your outgoing email messages and secure your mailboxes further by permitting e-mail messages to be sent only if the domain name involved features our MX records i.e. the e-mail messages for the domain name need to be managed on our end and not by some other supplier. In this way you'll get even better control and there will not be any chances for anybody to fake your emails for malicious objectives.
