SPF, which is an acronym for Sender Policy Framework, is an email security system, that is designed to validate if an e-mail message is sent by a certified server. Using SPF protection for a particular domain will prevent the forging of email addresses made with the domain. In simple words: enabling this feature for a domain makes a particular record in the Domain Name System (DNS) which includes the IP of the servers which are permitted to send e-mail messages from mailboxes under the domain. As soon as this record propagates globally, it will exist on all DNS servers that route the Internet traffic. Every time a new email message is sent, the first DNS server it goes through verifies whether it comes from an approved server. If it does, it is forwarded to the destination address, however when it does not originate from a server indexed in the SPF record for the domain, it's discarded. In this way nobody can mask an e-mail address and make it appear as if you're distributing spam. This approach is also termed email spoofing.

SPF Protection in Shared Hosting

When you host your domain names in a shared hosting account on our end and we manage the e-mails for them, you are able to activate SPF protection for any of them with several clicks in your Hepsia Control Panel. This service can be found in a section of its own where you will be able to view which domain names are already secured. For those that aren't, you can activate the SPF protection solution and manage a number of things during this process - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of the servers, and to create a rule that emails can be sent only when your domain names include our MX records. The last solution is the most secure one, and it can be used if we manage the emails for your domain names and you're not using a different email provider. The newly generated records will propagate within 1 day and nobody will be able to forge the FROM field in a message using your addresses.

SPF Protection in Semi-dedicated Servers

If you host your domain names in a semi-dedicated server account with us, you are able to use the SPF protection feature as a part of the standard collection of services that you will receive using this type of hosting. Starting the protection will require just a couple of simple steps within the Hepsia Control Panel, so even in the event that you have never employed this kind of feature before, you won't have any type of problems. Employing a very intuitive interface, you will just need to input the details of the mail server which will be permitted to send out messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the newly created record propagates, nobody will be able to counterfeit any e-mail address for that particular domain name and send messages from a server different from the one you have entered. This does not necessarily have to be our mail server, however in case we take care of your emails, you will be able to enable an additional level of protection by choosing an option that e-mails can be send from addresses @your-domain.com only in the event that the domain employs our MX records. Our tech support crew can assist you 24/7 if you have any questions regarding this service.
