SPF, which is an acronym for Sender Policy Framework, is an e-mail protection system, which is employed to verify if an e-mail message is sent by an authorized server. Employing SPF protection for a domain will prevent the faking of email addresses created with the domain. In simple words: activating this function for a domain name generates a specific record in the Domain Name System (DNS) containing the IP of the servers which are allowed to send e-mail messages from mail boxes using the domain. When this record propagates worldwide, it will exist on all the DNS servers that direct the Internet traffic. When an e-mail message is sent, the first DNS server it uses verifies if it originates from an official server. When it does, it is forwarded to the destination address, however if it does not originate from a server indexed in the SPF record for the domain, it's rejected. Thus nobody can mask an e-mail address to make it look as if you are e-mailing spam messages. This method is also referred to as email spoofing.

SPF Protection in Hosting

You're able to activate the SPF protection option for your domain names with a few clicks in the Hepsia Control Panel, which comes with all of our Linux hosting. This is done from the section with an identical name and you can enable the protection for any domain on our hi-tech cloud platform. Using a really convenient interface, all you need to submit is the hostname of the mail server that will be approved to send messages from your e-mail addresses and its IPv4 or IPv6 address. Of course, you are able to add several servers as well, when needed. In case your email addresses are taken care of by us, you may also employ an even more secure option by setting a limit that email messages can be sent only when your domains have our MX records. This alternative cannot be used in case your web site is hosted here, and your email addresses are with some third-party provider. Either way, the SPF protection solution can greatly increase your web security and prevent others from counterfeiting your email addresses.

SPF Protection in Semi-dedicated Servers

If you host your domains in a semi-dedicated server account with us, you are able to take advantage of the SPF protection feature as a part of the standard set of services that you will have with this kind of web hosting. Starting the protection involves only a few easy steps in the Hepsia Control Panel, thus even in case you've never used this kind of feature before, you won't have any kind of problems. Using a really time and effort saving interface, you'll just need to enter the info of the mail server which will be certified to send out messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the newly created record propagates, nobody will be able to fake any e-mail for that particular domain name and send messages from a server different from the one you've typed in. This does not necessarily have to be our mail server, but if we take care of your e-mails, you'll be able to activate an additional level of protection by choosing an option that e-mail messages can be send from addresses @your-domain.com only if the domain uses our MX records. Our technical support staff will be able to help you 24/7 if you have any kind of questions regarding this service.
