Sender Policy Framework, or SPF, is a verification system, that is designed to prevent the so-called e-mail spoofing where an email message is sent from one email, but to look as being sent from a different, typically with the idea to scam the recipient someway. When SPF protection is enabled for a domain name, a unique record is made for it in the Domain Name System and all DNS servers around the world have it. The record contains all e-mail servers that are allowed to send authentic messages from an email address under the domain. When a message is sent, the first DNS server it goes to verifies the SPF record and when its sending server is permitted, the message is sent to the target destination. When, however, the sending server is not included in the SPF record for the specified domain, the message won't be forwarded and it'll be removed. When you employ this solution, it'll prevent third parties from sending spam emails which seem to have been sent by you.

SPF Protection in Shared Website Hosting

If you host your domain names in a shared website hosting account with us and we handle the emails for them, you are able to activate SPF protection for them with a few clicks in your Hepsia Control Panel. This service is available in its own section where you can view which domain names are already protected. For the ones that are not, you will be able to enable the SPF protection option and manage numerous things during the process - the hostnames of the mail servers that are allowed to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, and even to create a rule that messages can be sent only if your domains use our MX records. The last choice is the most secure one, and you can use it when we handle the emails for your domain names and you're not using another e-mail provider. The newly generated records will propagate within a day and nobody will be able to forge the FROM field in an e-mail by using your addresses.

SPF Protection in Semi-dedicated Servers

If you host your domains in a semi-dedicated server account from us, you can use the SPF protection feature as a part of the standard set of services that you'll receive using this type of hosting. Activating the protection involves only a few easy steps inside the Hepsia Control Panel, so that even when you haven't employed this kind of function before, you won't have any kind of issues. Using an exceptionally easy to work with interface, you'll just need to input 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). As soon as the recently made record propagates, no one will be able to forge any email address for that particular domain name and send emails from a server different from the one you have entered. This does not specifically have to be our mail server, but if we handle your emails, you can enable an additional level of protection by choosing an option that e-mail messages can be send out from addresses @your-domain.com only if the domain uses our MX records. Our technical support staff can help you 24/7 if you have any kind of questions regarding this service.
