SPF, which stands for Sender Policy Framework, is an e-mail security system, which is used to confirm whether an email message is sent by a licensed server. Using SPF protection for a particular domain name will stop the counterfeiting of email addresses made with the domain. In layman's terms: enabling this feature for a domain name makes a specific record in the Domain Name System (DNS) which includes the IP addresses of the servers that are allowed to send e-mails from mailboxes under the domain. Once this record propagates worldwide, it exists on all DNS servers that direct the Internet traffic. When an email message is sent, the first DNS server it uses tests whether it comes from an accredited server. When it does, it is forwarded to the destination address, yet if it doesn't originate from a server part of the SPF record for the particular domain, it is discarded. Thus nobody will mask an e-mail address to make it look as if you're sending spam. This technique is also identified as email spoofing.

SPF Protection in Web Hosting

SPF protection can be activated for each domain hosted in a web hosting account on our cloud hosting platform with no more than a few clicks. The function is available in the Emails section of our modern Hepsia Control Panel and all you need to activate it is to choose one of your domain names from a drop-down menu and enter the hostnames plus the IPv4 or IPv6 addresses of the mail servers which will be authorized to send messages from your emails. As an additional option you can also restrict the emails to be sent from your domain name only if it includes our MX records, i.e. if our servers handle the email addresses for it, not a third-party supplier. This option will provide you with the best standard of protection, but it's not applicable when only your website is on our servers while the emails for the domain name are taken care of elsewhere. Either way, our SPF protection service will keep your emails secure from being used for spam or scam purposes.

SPF Protection in Semi-dedicated Servers

If you host your domain names in a semi-dedicated server account from our company, you will be able to employ the SPF protection feature as a part of the regular collection of services that you'll receive using this type of web hosting. Enabling the protection will involve just a couple of easy steps in the Hepsia Control Panel, thus even in the event that you've never employed this kind of feature before, you won't have any type of issues. Using a very easy-to-navigate interface, you'll just have to type in the details of the mail server that will be certified to send out messages from your e-mail addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). Once the newly generated record propagates, no one will be able to forge any email address for that particular domain and send out messages from a server different from the one you have entered. This does not necessarily have to be our mail server, but in case we handle your email messages, you can allow an additional level of security by picking 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 crew will be able to assist you 24/7 in case you have any questions regarding this service.
