SPF, which means Sender Policy Framework, is an e-mail protection system, which is used to verify whether an e-mail message is sent by an authorized server. Employing SPF protection for a given domain will stop the forging of emails generated with the domain. In layman's terms: activating this attribute for a domain creates a specific record in the Domain Name System (DNS) containing the IP of the servers that are permitted to send email messages from mailboxes using the domain. The moment this record propagates worldwide, it will exist on all of the DNS servers that direct the Internet traffic. Any time some email message is sent, the initial DNS server it uses tests if it originates from an authorized server. If it does, it is forwarded to the destination address, but if it doesn't come from a server part of 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 distributing spam. This approach is also identified as email spoofing.
SPF Protection in Hosting
SPF protection can be enabled for every domain name hosted in a hosting account on our cloud platform with no more than a few mouse-clicks. The feature is available in the Emails section of our amazing Hepsia Control Panel and what is needed to enable it is to choose one of your domain names from a drop-down list and enter the hostnames and the IPv4 or IPv6 addresses of the email servers which will be authorized to send emails from your email addresses. 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 emails for it, not a third-party provider. This option will give you the highest standard of security, but it is not applicable if only your site is on our servers while your emails for the domain name are handled in a different place. In either case, our SPF protection service will keep your emails protected from being used for spam and scam purposes.
SPF Protection in Semi-dedicated Hosting
If you host your domains in a semi-dedicated server account with us, you can employ the SPF protection feature as a part of the regular set of services that you will have using this kind of hosting. Starting the protection involves just a few easy steps within the Hepsia Control Panel, so that even if you've never employed this kind of function before, you won't have any troubles. Employing a very user-friendly interface, you'll only 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). Once the recently made record propagates, no one will be able to counterfeit any e-mail address for that particular domain and send out e-mail messages from a server other than the one you have entered. This doesn't specifically have to be our mail server, yet if we take care of your email messages, you are able to activate one more level of protection by choosing an option that e-mail messages can be send out 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 in case you have any kind of questions related to this service.
