SPF, which is an acronym for Sender Policy Framework, is an e-mail protection system, that is designed to validate if an email message is sent by an official server. Using SPF protection for a particular domain name will prevent the counterfeiting 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) that contains the IP addresses of the servers that are allowed to send e-mails from mailboxes using the domain. The moment this record propagates globally, it exists on all the DNS servers that route the Internet traffic. When a new email message is sent, the first DNS server it uses tests if it originates from an authorized server. In the event it does, it is forwarded to the destination address, but if it doesn't originate from a server part of the SPF record for the domain, it is discarded. In this way nobody will be able to mask an email address then make it appear as if you are distributing spam messages. This method is also identified as email spoofing.

SPF Protection in Cloud Hosting

When you host your domains in a cloud hosting account with us and we handle the e-mail addresses for them, you will be able to activate SPF protection for them with a couple of clicks inside your Hepsia Control Panel. The service can be found in a section of its own where you're able to see which domain names are currently secured. For the ones which aren't, you can activate the SPF protection option and manage a variety of things during this process - the hostnames of the mail servers that are allowed to send messages from your addresses, the IPv4 and IPv6 addresses of these servers, and to create a rule that messages can be sent only when your domain names have our MX records. The last option is the most secure one, but you can use it in the event that we take care of the e-mail addresses for your domain names and you're not using some other email supplier. The new records will be activated within 1 day and nobody will be able to fake the FROM field in an email using your e-mail addresses.
