SPF, which is an acronym for Sender Policy Framework, is an e-mail security system, that is is intended to confirm whether an e-mail message was sent by a licensed server. Employing SPF protection for a given domain will stop the forging of emails generated with the domain. In layman's terms: enabling this feature for a domain creates a specific record in the Domain Name System (DNS) which includes the IP of the servers which are permitted to send e-mail messages from mailboxes under the domain. Once this record propagates worldwide, it will exist on all of the DNS servers that direct the Internet traffic. Any time an email message is sent, the initial DNS server it goes through verifies if it comes from an accredited server. When it does, it's sent to the destination address, however if it does not come from a server indexed in the SPF record for the domain, it's discarded. Thus nobody can mask an email address to make it appear as if you are distributing spam. This approach is also called email spoofing.

SPF Protection in Cloud Hosting

You are able to enable the SPF protection service for your domain names with just a few clicks inside the Hepsia Control Panel, which is provided with our Linux cloud hosting service. This is performed through the section with the very same name and you are able to allow the protection for any domain name on our cutting-edge cloud hosting platform. Using a very simple interface, all you will need to submit is the hostname of the mail server that will be approved to send messages from your e-mails and its IPv4 or IPv6 address. Of course, you'll be able to add several servers too, if needed. When your e-mail addresses are managed by us, you may also employ a more secure option by placing a limit that e-mail messages can be sent only if your domain names feature our MX records. This solution can't be applied in case your site is hosted here, and the e-mails are with some third-party service provider. Either way, the SPF protection solution will definitely increase your web security and prevent others from spoofing your email addresses.

SPF Protection in Semi-dedicated Servers

The Hepsia Control Panel, which comes with the semi-dedicated accounts, has a really easy to use interface, therefore you don't have to be proficient in the use of computers in order to protected your e-mails. You'll simply have to type the hostname and the IP address of each mail server that you would like to be authorized to send out emails from your addresses and shortly after that the updated record will be activated for the domain that you've chosen. As an extra option, we'll also allow you to limit the outgoing e-mail messages and secure your mailboxes even further by allowing email messages to be sent only if the domain in question includes our MX records i.e. the email messages for the domain have to be handled by us and not by some other company. Thus you will enjoy even superior control and there will not be any chances for anyone to counterfeit your e-mail addresses for harmful intentions.
