SPF, which stands for Sender Policy Framework, is an e-mail safety system, that is designed to validate whether an e-mail message was sent by a licensed server. Using SPF protection for a particular domain will prevent the faking of email addresses made with the domain. In simple words: enabling this function for a domain creates a particular record in the Domain Name System (DNS) containing the IP addresses of the servers that are allowed to send e-mail messages from mail boxes using the domain. As soon as this record propagates worldwide, it exists on all of the DNS servers that route the Internet traffic. When some e-mail message is sent, the first DNS server it uses checks whether it comes from an approved server. If it does, it's forwarded to the destination address, yet when it doesn't originate from a server listed in the SPF record for the particular domain, it is rejected. Thus nobody can mask an email address and make it look as if you're distributing spam messages. This approach is also referred to as email spoofing.

SPF Protection in Web Hosting

SPF protection can be activated for any domain name hosted in a web hosting account on our cloud platform with just a few clicks. The option can be found in the Emails section of our outstanding Hepsia Control Panel and all you need to use it is to pick one of your domains from the drop-down list and then enter the hostnames plus the IPv4 or IPv6 addresses of the e-mail servers which will be approved to send emails from your email addresses. As an additional option you can even restrict the messages to be sent from your domain only when it has our MX records, i.e. when our servers handle the e-mail addresses for it, not a third-party provider. This solution gives you the best level of protection, but it's not applicable if only your web site is on our servers while your email addresses for the domain name are managed in another place. Regardless, our SPF protection service will keep your email addresses protected from being used for spam and/or scam purposes.
