SPF, which is short for Sender Policy Framework, is an e-mail protection system, which is used to confirm whether an e-mail message is sent by a certified server. Employing SPF protection for a particular domain name will stop the counterfeiting of emails generated with the domain. In layman's terms: activating this feature for a domain name creates a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers that are allowed to send emails from mailboxes using the domain. As soon as this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. Whenever an email message is sent, the initial DNS server it goes through checks if it comes from an authorized server. When it does, it is sent to the destination address, however if it doesn't originate from a server part of the SPF record for the domain, it's rejected. Thus nobody will mask an email address and make it appear as if you're distributing spam messages. This method is also known as email spoofing.
SPF Protection in Shared Hosting
You are able to enable the SPF protection service for your domains with just a couple of clicks inside the Hepsia Control Panel, which comes with our Linux shared hosting. This is performed via the section with the same name and you can enable the protection for each and every domain name on our cutting-edge cloud platform. Using a really time and effort saving interface, all you'll need to enter is the hostname of the mail server that will be authorized to send messages from your e-mails and its IPv4 or IPv6 address. Of course, you can include several servers too, when needed. If your emails are managed on our end, you may also take advantage of an even more secure option by setting a restriction that emails can be sent only if your domain names have our MX records. This option cannot be applied when your website is hosted with us, while the e-mail addresses are with some third-party provider. Either way, the SPF protection option will strongly improve your online protection and prevent others from counterfeiting your e-mail addresses.
SPF Protection in Semi-dedicated Servers
When you host your domains in a semi-dedicated server account with our company, you'll be able to take advantage of the SPF protection feature as a part of the regular group of services that you'll get with this kind of website hosting. Enabling the protection will involve only several easy steps in the Hepsia Control Panel, so even in case you have never employed such a function before, you will not have any issues. Employing an exceptionally easy-to-navigate interface, you'll only have to input the details of the mail server that will be certified to send messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the recently created record propagates, no one will be able to forge any e-mail for that particular domain name and send emails from a server other than the one you've typed in. This doesn't necessarily have to be our mail server, yet when we take care of your emails, you are able to enable an additional level of protection by selecting an option that e-mail messages can be send from addresses @your-domain.com only in case the domain uses our MX records. Our tech support crew can help you 24/7 in case you have any kind of questions regarding this service.
