SPF, which means Sender Policy Framework, is an email safety system, which is used to confirm if an email message is sent by a licensed server. Using SPF protection for a domain will stop the faking of emails made with the domain. In simple words: enabling this feature for a domain generates a particular record in the Domain Name System (DNS) which contains the IP addresses of the servers that are permitted to send e-mail messages from mail boxes under the domain. Once this record propagates worldwide, it will exist on all of the DNS servers that direct the Internet traffic. Any time an e-mail message is sent, the initial DNS server it goes through tests whether it originates from an official server. If it does, it's forwarded to the destination address, but when it doesn't come from a server part of the SPF record for the particular domain, it's rejected. In this way nobody will be able to mask an email address and make it appear as if you are sending spam. This method is also termed email spoofing.

SPF Protection in Cloud Web Hosting

When you host your domains in a cloud web hosting account with us and we handle the emails for them, you'll be able to enable SPF protection for all of them with several clicks in your Hepsia Control Panel. The service is available in a separate section where you'll be able to see which domains are already secured. For the ones which aren't, you will be able to enable the SPF protection option and set up numerous things in the process - the hostnames of the mail servers that are allowed to send messages from your addresses, the IPv4 and IPv6 addresses of the servers, and to create a rule that messages can be sent only if your domain names include our MX records. The last mentioned solution is the most secure one, and you can use it in the event that we handle the email addresses for your domains and you're not using some other email provider. The newly created records will propagate within one day and nobody will be able to fake the FROM field in a message using your e-mail addresses.
