Sender Policy Framework, or SPF, is a validation system, which is designed to stop the so-called e-mail spoofing where an email message can be sent from one e-mail, but to look as being sent from another, usually with the idea to fraud the recipient someway. When SPF protection is enabled for a domain, a unique record is made for it in the Domain Name System and all DNS servers around the world have it. The record includes all the email servers that are allowed to send legitimate messages from an e-mail address within the domain. When an e-mail is sent, the very first DNS server it encounters checks the SPF record and in case its sending server is authorized, the message is forwarded to the targeted destination. When, however, the sending server is not contained in the SPF record for the particular domain, the message won't be submitted and it'll be removed. When you employ this service, it will prevent third parties from sending spam e-mails that seem to have been sent from you.

SPF Protection in Semi-dedicated Hosting

When you host your domain names in a semi-dedicated server account from us, you can use the SPF protection feature as part of the conventional set of services that you will have using this kind of web hosting. Activating the protection involves only a few easy steps inside the Hepsia Control Panel, so even in case you've never used such a function before, you will not have any kind of troubles. Employing a really easy to work with interface, you'll only need to insert the information of the mail server which will be authorized to send out messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the recently made record propagates, no one will be able to fake any e-mail address for that particular domain and send messages from a server other than the one you've typed in. This doesn't necessarily have to be our mail server, however if we manage your email messages, you're able to activate an extra level of protection by choosing an option that emails can be send out from addresses @your-domain.com only in case the domain employs our MX records. Our technical support staff will be able to assist you 24/7 if you have any kind of questions regarding this service.
