SPF, which stands for Sender Policy Framework, is an email safety system, which is designed to validate if an email message is sent by a certified server. Using SPF protection for a given domain name will stop the counterfeiting of emails generated with the domain. In layman's terms: activating this function for a domain name makes a particular record in the Domain Name System (DNS) containing the IP of the servers that are permitted to send e-mails from mail boxes using the domain. Once this record propagates worldwide, it exists on all of the DNS servers that route the Internet traffic. Whenever an email message is sent, the initial DNS server it goes through tests if it originates from an official server. If it does, it's forwarded to the destination address, but when it does not originate from a server part of the SPF record for the domain, it is rejected. Thus nobody can mask an e-mail address and make it look as if you are sending spam messages. This method is also identified as email spoofing.
SPF Protection in Cloud Hosting
If you host your domains in a cloud hosting account on our end and we manage the email addresses for them, you are able to activate SPF protection for all of them with several clicks inside your Hepsia Control Panel. The service can be found in a section of its own where you'll be able to view which domains are currently secured. For the ones that aren't, you'll be able to activate the SPF protection option and configure a number of things during the process - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of these servers, as well as to set a rule that emails can be sent only if your domains include our MX records. The aforementioned choice is the most secure one, but you can use it when we manage the email addresses for your domains and you are not using some other email provider. The newly created records will propagate within a day and nobody will be able to forge the FROM field in a message with your e-mail addresses.
