SPF, which means Sender Policy Framework, is an email safety system, that is used to confirm if an email message was sent by an authorized server. Using SPF protection for a given domain will prevent the forging of email addresses created with the domain. In layman's terms: enabling this feature for a domain generates a specific record in the Domain Name System (DNS) which includes the IP addresses of the servers which are allowed to send e-mails from mailboxes using the domain. When this record propagates globally, it exists on all of the DNS servers that route the Internet traffic. Whenever an email message is sent, the initial DNS server it uses checks if it originates from an authorized server. In the event it does, it is forwarded to the destination address, but if it doesn't come from a server part of the SPF record for the particular domain, it's rejected. Thus nobody will mask an email address then make it look as if you are distributing spam messages. This approach is also called email spoofing.

SPF Protection in Cloud Website Hosting

You can enable the SPF protection service for your domain names with just a couple of clicks inside the Hepsia Control Panel, which comes with all our Linux cloud website hosting. This carried out via the section with the same name and you'll be able to set up the protection for each domain on our advanced cloud platform. Using a really simple interface, all you have to submit is the hostname of the mail server which will be approved to send messages from your e-mails and its IPv4 or IPv6 address. Of course, you are able to add several servers too, if needed. If your e-mails are handled on our end, you may also use a more secure option by placing a limit that messages can be sent only when your domains have our MX records. This option cannot be used in case your site is here, while your e-mail addresses are with some third-party provider. In either case, the SPF protection option will tremendously enhance your online security and prevent others from forging your email addresses.

SPF Protection in Semi-dedicated Hosting

When you have a semi-dedicated server account from our company, you can secure your emails by activating the SPF protection service for every domain in your account with only a couple of mouse-clicks. This can be done in the Emails section of the Hepsia Control Panel which is included with the semi-dedicated accounts and even if you lack previous experience with such matters, you won't have any trouble to activate the security. Everything that you'll need to do will be to find a domain name from a drop-down menu and after that type the mail server hostname and IPv4 or IPv6 address. The moment the updated record propagates, messages from your e-mail addresses will be delivered worldwide only if they are sent from that specific server. When your e-mail addresses are handled by our company and not by a third-party supplier, you can also use an option for email messages to be sent only if the domain has our MX records and the aforementioned would be the safest option. In case you have any kind of questions regarding thisfeature, you'll be able to contact our tech support team 24/7.
