Sender Policy Framework, or SPF, is a verification system, that is used to stop the so-called email spoofing where an email message can be sent from one e-mail address, but to seem as being sent from a different one, typically with the idea to fraud the recipient for some reason. When SPF protection is enabled for a domain name, a unique record is generated for it in the Domain Name System and all of the DNS servers worldwide get it. The record includes all of the e-mail servers that are permitted to send legitimate messages from an address part of the domain. When a message is sent, the very first DNS server it goes to verifies the SPF record and when its sending server is authorized, the message is sent to the targeted destination. If, however, the sending server is not included in the SPF record for the specified domain, the email message will not be sent and it'll be removed. When you employ this service, it will stop third parties from sending spam that appear to have been sent from you.
SPF Protection in Website Hosting
If you host your domain names in a website hosting account on our end and we manage the emails for them, you'll be able to enable SPF protection for them with several clicks inside your Hepsia Control Panel. The service can be found in a section of its own where you're able to view which domains are already protected. For those that are not, you can activate the SPF protection service and set up a lot of things at the same time - the hostnames of the mail servers that are allowed to send messages from your email addresses, the IPv4 and IPv6 addresses of the servers, and even to set a rule that messages can be sent only if your domains use our MX records. The last solution is the most secure one, but it can be used when we take care of the emails for your domains and do not use some other email provider. The newly created records will be activated within a day and nobody will be able to fake the FROM field in an e-mail with your addresses.
