SPF, which means Sender Policy Framework, is an email security system, which is employed to validate if an e-mail message is sent by a licensed server. Using SPF protection for a domain name will stop the faking of email addresses created with the domain. In layman's terms: enabling this function for a domain generates a special record in the Domain Name System (DNS) which includes the IP of the servers that are allowed to send e-mail messages from mailboxes using the domain. When this record propagates globally, it will exist on all DNS servers that direct the Internet traffic. Any time a new e-mail message is sent, the first DNS server it uses verifies if it comes from an official server. When it does, it is forwarded to the destination address, yet when it does not originate from a server indexed in the SPF record for the domain, it's rejected. Thus nobody will mask an e-mail address to make it appear as if you are distributing spam. This method is also referred to as email spoofing.

SPF Protection in Cloud Hosting

When you host your domains in a cloud hosting account on our end and we manage the e-mails for them, you are able to enable SPF protection for them with a couple of clicks inside your Hepsia Control Panel. The service can be found in a separate section where you can see which domain names are already protected. For those which aren't, you will be able to enable the SPF protection solution and manage a variety of things at the same time - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of these servers, and to set a rule that messages can be sent only when your domain names use our MX records. The last solution is the most secure one, and you can use it in the event that we handle the email addresses for your domains and you are not using a different email service provider. The new records will propagate within 24 hours and nobody will be able to forge the FROM field in an email using your e-mail addresses.

SPF Protection in Semi-dedicated Servers

If you host your domain names in a semi-dedicated server account with our company, you are able to employ the SPF protection feature as part of the regular set of services that you'll get using this type of web hosting. Starting the protection involves only a couple of simple steps inside the Hepsia Control Panel, so that even if you've never used this kind of function before, you will not have any kind of troubles. Using an exceptionally easy-to-navigate interface, you will simply need to insert the information of the mail server which will be permitted to send out messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the newly generated record propagates, nobody will be able to fake any email for that particular domain name and send e-mails from a server different from the one you have entered. This doesn't specifically have to be our mail server, but if we manage your e-mails, you will be able to enable an additional level of protection by selecting an option that e-mail messages can be send out from addresses @your-domain.com only if the domain uses our MX records. Our tech support team can assist you 24/7 if you have any questions about this service.
