SPF, which means Sender Policy Framework, is an e-mail security system, which is used to confirm whether an e-mail message was sent by a certified server. Employing SPF protection for a domain name will stop the forging of email addresses created with the domain. In layman's terms: activating this function for a domain name makes a specific record in the Domain Name System (DNS) which contains the IP of the servers that are permitted to send emails from mail boxes using the domain. Once this record propagates globally, it exists on all of the DNS servers that direct the Internet traffic. Every time a new email message is sent, the initial DNS server it uses checks if it comes from an official server. When it does, it is forwarded to the destination address, yet when it doesn't originate from a server part of the SPF record for the domain, it's discarded. In this way nobody will be able to mask an email address and make it appear as if you're distributing spam messages. This method is also referred to as email spoofing.

SPF Protection in Cloud Hosting

When you host your domain names in a cloud hosting account with us and we handle the email addresses for them, you are able to enable SPF protection for all of them with a few clicks in your Hepsia Control Panel. The service can be found in a section of its own where you are able to see which domain names are already protected. For those that aren't, you will be able to activate the SPF protection solution and manage numerous things during the process - the hostnames of the mail servers that are allowed to send messages from your email addresses, the IPv4 and IPv6 addresses of these servers, and even to create a rule that email messages can be sent only if your domain names use our MX records. The last mentioned option is the most secure one, and it can be used if we handle the emails for your domain names and you are not using a different email supplier. The new records will be activated within 24 hours and nobody will be able to forge the FROM field in a message by using your e-mail addresses.

SPF Protection in Semi-dedicated Servers

If you host your domains in a semi-dedicated server account from our company, you can take advantage of the SPF protection feature as a part of the regular group of services that you will receive using this kind of hosting. Enabling the protection will require only a few simple steps inside the Hepsia Control Panel, therefore even in the event that you've never employed this kind of function before, you will not have any type of troubles. Using a very easy-to-navigate interface, you will just have to insert the details of the mail server that will be certified to send messages from your email addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). The moment the newly made record propagates, nobody will be able to counterfeit any e-mail for that particular domain name and send email messages from a server other than the one you've typed in. This doesn't specifically have to be our mail server, but if we handle your email messages, you can allow an additional level of protection by selecting an option that e-mails 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 if you have any kind of questions regarding this service.
