Sender Policy Framework, or SPF, is a validation system, that is employed to prevent the so-called email spoofing where an e-mail message is sent from one address, but to look as being sent from a different, often with the objective to scam the recipient someway. When SPF protection is enabled for a domain, a specific record is made for it in the Domain Name System and all the DNS servers around the world receive it. The record includes all of the mail servers that are allowed to send legitimate messages from an email address under the domain. When a message is sent, the very first DNS server it goes to verifies the SPF record and if its sending server is authorized, the message is sent to the target receiver. If, however, the sending server is not contained in the SPF record for the given domain, the message will not be sent and it will be removed. When you use this solution, it will prevent third parties from sending spam messages that seem to have been sent from you.

SPF Protection in Hosting

SPF protection can be activated for every domain name hosted in a hosting account on our cloud hosting platform with no more than a few clicks. The option can be found in the Emails section of our state-of-the-art Hepsia Control Panel and what is needed to use it is to choose one of your domain names from a drop-down list and enter the hostnames along with the IPv4 or IPv6 addresses of the email servers that will be certified to send email messages from your email addresses. As an additional option you may also restrict the e-mails to be sent from your domain only when it has our MX records, in other words when our servers handle the email addresses for it, not some third-party supplier. This option gives you the best level of safety, but it is not applicable in case only your website is on our servers while your e-mail addresses for the domain name are taken care of in a different place. In either case, the SPF protection service will keep your emails safe from being used for spam and/or scam purposes.
