SPF, which is short for Sender Policy Framework, is an email safety system, which is used to confirm if an e-mail message is sent by a certified server. Using SPF protection for a given domain name will prevent the counterfeiting of email addresses created with the domain. In simple words: activating this function for a domain name makes a special record in the Domain Name System (DNS) that contains the IP of the servers which are allowed to send e-mail messages from mailboxes under the domain. As soon as this record propagates globally, it will exist on all DNS servers that direct the Internet traffic. Every time a new email message is sent, the initial DNS server it goes through verifies whether it comes from an authorized server. In the event it does, it is sent to the destination address, however when it does not originate from a server indexed in the SPF record for the domain, it is rejected. In this way nobody can mask an email address to make it appear as if you're distributing spam messages. This technique is also called email spoofing.
SPF Protection in Cloud Web Hosting
If you host your domains in a cloud web hosting account on our end and we manage the email addresses for them, you will be able to enable SPF protection for them with a few clicks inside your Hepsia Control Panel. This service is accessible in its own section where you're able to view which domain names are currently protected. For the ones that are not, you can enable the SPF protection option and configure various things during this process - the hostnames of the mail servers that are permitted to send messages from your addresses, the IPv4 and IPv6 addresses of the servers, and even to create a rule that emails can be sent only if your domains include our MX records. The aforementioned choice is the most secure one, and it can be used when we take care of the email addresses for your domain names and you are not using a different email supplier. The newly created records will be activated within 24 hours and nobody will be able to fake the FROM field in an email using your e-mail addresses.
