Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called e-mail spoofing where an email message can be sent from one e-mail address, but to seem as being sent from a different one, often with the idea to fraud the recipient someway. If SPF protection is enabled for a domain, an exclusive record is made for it in the Domain Name System and all of the DNS servers globally have it. The record contains all e-mail servers that are permitted to send valid messages from an e-mail address under the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and when the sending server is authorized, the message is sent to the targeted receiver. In case, however, the sending server is not present in the SPF record for the specified domain, the message won't be sent and it will be removed. When you use this solution, it will prevent third parties from sending spam that appear to have been sent from you.

SPF Protection in Shared Hosting

SPF protection can be activated for every domain name hosted in a shared hosting account on our cloud platform with just a few clicks. The option can be found in the Emails section of our innovative Hepsia Control Panel and all you need to use it is to choose one of your domain names from a drop-down menu and then enter the hostnames along with the IPv4 or IPv6 addresses of the email servers which will be permitted to send messages from your email addresses. As an added option you can also restrict the emails to be sent from your domain name only if it has our MX records, in other words when our servers handle the emails for it, not some third-party provider. This option provides you with the highest standard of safety, but it's not applicable in case only your site is on our servers while the e-mail addresses for the domain are taken care of in another place. Regardless, our SPF protection service will keep your emails safe from being used for spam or scam purposes.
