Sender Policy Framework, or SPF, is a verification system, which is designed to prevent the so-called email spoofing where an email message can be sent from one email address, but to seem as being sent from another, usually with the purpose to scam the recipient someway. If SPF protection is enabled for a domain, a unique record is made for it in the Domain Name System and all of the DNS servers worldwide have it. The record includes all of the email servers that are allowed to send authentic messages from an e-mail address under the domain. When an e-mail is sent, the very first DNS server it encounters checks the SPF record and when its sending server is permitted, the message is forwarded to the targeted receiver. When, however, the sending server doesn't exist in the SPF record for the given domain, the e-mail message won't be forwarded and it will be removed. In case you use this service, it'll prevent third parties from sending spam emails which seem to have been sent by you.

SPF Protection in Web Hosting

SPF protection can be enabled for each domain name hosted in a web hosting account on our cloud platform with no more than a couple of clicks. The option is available in the Emails section of our innovative Hepsia Control Panel and what is needed to enable it is to pick one of your domain names from a drop-down menu and type in the hostnames together with the IPv4 or IPv6 addresses of the mail servers that will be authorized to send email messages from your emails. As an additional option you can also restrict the messages to be sent from your domain name only when it includes our MX records, i.e. if our servers handle the emails for it, not a third-party provider. This feature provides you with the top level of safety, but it's not applicable if only your website is on our servers while your email addresses for the domain are managed elsewhere. In either case, our SPF protection service will keep your email addresses protected from being used for spam or scam purposes.
