Sender Policy Framework, or SPF, is a verification system, which is designed to prevent the so-called email spoofing where an e-mail message can be sent from one e-mail address, but to seem as being sent from a different one, typically with the purpose to fraud the recipient for some reason. If SPF protection is activated for a domain name, a unique record is created for it in the Domain Name System and all DNS servers globally get it. The record includes all e-mail servers that are allowed to send authentic messages from an e-mail address under the domain. When an email is sent, the first DNS server it encounters checks the SPF record and in case its sending server is permitted, the message is sent to the target destination. In case, however, the sending server doesn't exist in the SPF record for the given domain, the message will not be submitted and it will be discarded. If you employ this service, it'll prevent third parties from sending spam emails which appear to have been sent by you.

SPF Protection in Web Hosting

When you host your domain names in a web hosting account with us and we handle the email addresses for them, you will be able to activate SPF protection for any of them with a few clicks inside your Hepsia Control Panel. The service can be found in a section of its own where you're able to view which domain names are currently protected. For those that are not, you can activate the SPF protection service and manage a lot of things during this process - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of the servers, as well as to set a rule that email messages can be sent only when your domains have our MX records. The last mentioned choice is the most secure one, and you can use it in the event that we take care of the e-mail addresses for your domains and do not use some other email service provider. The new records will propagate within a day and nobody will be able to fake the FROM field in an e-mail using your e-mail addresses.
