SPF, which means Sender Policy Framework, is an email security system, that is designed to confirm if an email message is sent by an official server. Employing SPF protection for a particular domain will prevent the counterfeiting of email addresses created with the domain. In simple words: enabling this attribute for a domain generates a particular record in the Domain Name System (DNS) which includes the IP addresses of the servers which are permitted to send email messages from mailboxes using the domain. When this record propagates globally, it will exist on all DNS servers that direct the Internet traffic. Every time a new email message is sent, the first DNS server it uses checks if it originates from an approved server. If it does, it's forwarded to the destination address, however when it does not originate from a server part of the SPF record for the domain, it's discarded. In this way nobody will be able to mask an email address then make it appear as if you are sending spam messages. This approach is also termed email spoofing.

SPF Protection in Shared Website Hosting

You can activate the SPF protection option for your domains with only a few clicks from the Hepsia Control Panel, which comes with our Linux shared website hosting. This is done via the section with the same name and you'll be able to allow the protection for any domain part of our exceptional cloud platform. Using a very convenient interface, all you have to type in is the hostname of the mail server that will be authorized to send out messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you can include several servers too, when needed. If your emails are handled by us, you can also employ a more risk-free option by placing a restriction that messages can be sent only if your domains include our MX records. This alternative cannot be applied when your website is hosted with us, and the e-mails are with some third-party provider. In either case, the SPF protection option can considerably improve your online security and prevent others from forging your e-mail addresses.

SPF Protection in Semi-dedicated Hosting

If you host your domains in a semi-dedicated server account with us, you can use the SPF protection feature as a part of the standard collection of services that you will receive with this type of web hosting. Starting the protection will require only a couple of simple steps inside the Hepsia Control Panel, therefore even in case you've never employed this kind of feature before, you won't have any kind of problems. Using an exceptionally user-friendly interface, you'll only need to insert the info of the mail server that will be permitted to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the recently made record propagates, no one will be able to forge any email address for that particular domain and send out emails from a server other than the one you've typed in. This doesn't necessarily have to be our mail server, but in case we manage your email messages, you are able to allow an additional level of protection by selecting an option that email messages can be send out from addresses @your-domain.com only in the event that the domain uses our MX records. Our tech support crew will be able to assist you 24/7 if you have any questions related to this service.
