Sender Policy Framework, or SPF, is a validation system, that is used to prevent the so-called email spoofing where an email message can be sent from one address, but to look as being sent from another one, generally with the objective to scam the recipient in some way. When SPF protection is enabled for a domain name, a special record is created for it in the Domain Name System and all DNS servers worldwide have it. The record contains all of the e-mail servers that are allowed to send valid messages from an address under the domain. When a message is sent, the first DNS server it goes to checks the SPF record and if the sending server is authorized, the message is sent to the target receiver. If, however, the sending server is not included in the SPF record for the given domain, the e-mail message will not be submitted and it'll be discarded. Whenever you use this solution, it will prevent third parties from sending spam emails which seem to have been sent from you.

SPF Protection in Cloud Web Hosting

You can activate the SPF protection service for your domain names with a couple of clicks inside the Hepsia Control Panel, which is included with all of our cloud web hosting plans. This is done via the section with the same name and you can enable the protection for any domain name hosted on our modern cloud platform. Using a really convenient interface, all you will have to type in is the hostname of the mail server which will be authorized to send messages from your emails and its IPv4 or IPv6 address. Of course, you are able to add several servers too, if needed. In case your emails are managed on our end, you may also employ a more secure option by putting a restriction that email messages can be sent only if your domain names have our MX records. This option cannot be applied if your website is hosted here, while the e-mail addresses are with some third-party service provider. Either way, the SPF protection option can vastly enhance your web protection and prevent others from counterfeiting your e-mail addresses.

SPF Protection in Semi-dedicated Servers

If you host your domains in a semi-dedicated server account with our company, you'll be able to employ the SPF protection feature as a part of the regular group of services that you'll receive using this kind of website hosting. Activating the protection involves only a couple of simple steps in the Hepsia Control Panel, therefore even in case you haven't used this kind of function before, you won't have any type of troubles. Employing a really easy to work with interface, you'll simply have to input the details of the mail server which will be certified to send messages from your e-mail addresses - its hostname ( and IP address (IPv4 or IPv6). The moment the newly made record propagates, no one will be able to forge any e-mail address for that particular domain name and send e-mail messages from a server different from the one you've entered. This does not necessarily have to be our mail server, still if we take care of your e-mails, you're able to allow an additional level of protection by selecting an option that e-mail messages can be send out from addresses only in case the domain employs our MX records. Our technical support staff can assist you 24/7 in case you have any questions related to this service.
