Sender Policy Framework, or SPF, is a validation system, that is employed to stop the so-called e-mail spoofing where an e-mail message can be sent from one e-mail, but to look as being sent from another one, frequently with the objective to scam the recipient for some reason. When SPF protection is activated for a domain name, a unique record is made for it in the Domain Name System and all the DNS servers globally receive it. The record includes all of the email servers that are allowed to send valid messages from an e-mail address part of the domain. When an email is sent, the first DNS server it encounters checks the SPF record and if the sending server is permitted, the message is forwarded to the targeted destination. In case, however, the sending server doesn't exist in the SPF record for the specified domain, the message will not be submitted and it will be removed. Whenever you employ this service, it will prevent third parties from sending spam messages which look as if they have been sent from you.

SPF Protection in Hosting

SPF protection can be activated for each domain hosted in a hosting account on our cloud hosting platform with only a couple of mouse-clicks. The function can be found in the Emails section of our cutting-edge Hepsia Control Panel and what is needed to enable it is to pick one of your domain names from a drop-down list and enter the hostnames together with the IPv4 or IPv6 addresses of the email servers which will be approved to send email messages from your emails. As an added option you can even restrict the emails to be sent from your domain only when it includes our MX records, i.e. if our servers manage the e-mail addresses for it, not some third-party provider. This feature will give you the top level of protection, but it is not applicable if only your website is on our servers while the email addresses for the domain name are managed elsewhere. Either way, our SPF protection service will keep your email addresses secure from being used for spam and scam purposes.
