Sender Policy Framework, or SPF, is a validation system, which is employed to stop the so-called e-mail spoofing where an email message can be sent from one email address, but to seem as being sent from another one, generally with the idea to scam the recipient for some reason. When SPF protection is activated for a domain, an exclusive record is made for it in the Domain Name System and all DNS servers globally get it. The record features all the mail servers that are allowed to send valid messages from an e-mail address part of the domain. When an email is sent, the very first DNS server it goes to verifies the SPF record and if its sending server is authorized, the message is sent to the target destination. If, however, the sending server is not present in the SPF record for the given domain, the email message will not be submitted and it will be removed. Whenever you use this service, it will stop third parties from sending spam which seem to have been sent from you.

SPF Protection in Cloud Hosting

You are able to activate the SPF protection option for your domain names with a couple of clicks inside the Hepsia Control Panel, which comes with all of our Linux cloud hosting. This is performed through the section with an identical name and you are able to set up the protection for each and every domain part of our leading-edge cloud platform. Using a very handy interface, all you'll need to type in is the hostname of the mail server that will be approved to send messages from your email addresses and its IPv4 or IPv6 address. Of course, you can add several servers too, when needed. In case your e-mail addresses are managed on our end, you can also take advantage of a more risk-free option by placing a restriction that email messages can be sent only when your domain names have our MX records. This option cannot be applied in case your website is here, while the e-mail addresses are with a third-party service provider. In either case, the SPF protection option will really improve your web security and prevent other people from spoofing your email addresses.

SPF Protection in Semi-dedicated Hosting

When you host your domain names in a semi-dedicated server account from us, you'll be able to use the SPF protection feature as part of the standard collection of services that you will have using this kind of hosting. Enabling the protection involves just a few easy steps in the Hepsia Control Panel, so that even if you've never used this type of feature before, you will not have any issues. Employing a very intuitive interface, you will only have to type in the details of the mail server which will be permitted to send out messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the newly generated record propagates, no one will be able to fake any e-mail for that particular domain and send e-mail messages from a server other than the one you've entered. This does not specifically have to be our mail server, yet when we handle your email messages, you'll be able to allow an additional level of security by selecting an option that emails can be send from addresses @your-domain.com only in case the domain uses our MX records. Our technical support crew will be able to help you 24/7 if you have any questions related to this service.
