SPF, which stands for Sender Policy Framework, is an e-mail protection system, that is used to verify whether an e-mail message was sent by a licensed server. Employing SPF protection for a particular domain will prevent the counterfeiting of email addresses generated with the domain. In layman's terms: activating this function for a domain generates a special record in the Domain Name System (DNS) which includes the IP of the servers that are permitted to send e-mails from mailboxes using the domain. When this record propagates globally, it exists on all the DNS servers that route the Internet traffic. Any time an e-mail message is sent, the initial DNS server it uses verifies whether it comes from an approved server. When it does, it is sent to the destination address, however if it does not come from a server listed in the SPF record for the particular domain, it is discarded. In this way nobody can mask an e-mail address then make it look as if you are sending spam messages. This technique is also identified as email spoofing.
SPF Protection in Cloud Website Hosting
SPF protection can be activated for each domain name hosted in a cloud website hosting account on our cloud platform with no more than a few mouse-clicks. The function can be found in the Emails section of our hi-tech Hepsia Control Panel and what is needed to activate it is to choose one of your domain names from a drop-down list and then type in the hostnames as well as the IPv4 or IPv6 addresses of the e-mail servers that will be approved to send messages from your emails. As an additional option you may also restrict the messages to be sent from your domain only if it includes our MX records, in other words when our servers manage the email addresses for it, not a third-party supplier. This solution provides you with the top level of safety, but it is not applicable if only your site is on our servers while your e-mail addresses for the domain name are handled somewhere else. Either way, the 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 domains in a semi-dedicated server account from us, you are able to employ the SPF protection feature as part of the standard group of services that you will get using this kind of web hosting. Starting the protection will require just a few simple steps in the Hepsia Control Panel, so even if you've never employed such a feature before, you won't have any issues. Employing a very easy-to-use interface, you'll only need to input the details of the mail server that will be authorized to send out messages from your addresses - its hostname (mail.server.com) and IP address (IPv4 or IPv6). As soon as the recently generated record propagates, no one will be able to fake any email for that particular domain name and send e-mail messages from a server other than the one you've typed in. This does not specifically have to be our mail server, but in case we handle your emails, you're able to allow an extra level of security by picking an option that e-mail messages can be send from addresses @your-domain.com only if the domain uses our MX records. Our technical support team can help you 24/7 in case you have any kind of questions regarding this service.
