Sender Policy Framework, or SPF, is a verification system, which is intended to prevent the so-called e-mail spoofing where an e-mail message can be sent from one e-mail, but to seem as being sent from a different one, often with the objective to fraud the recipient for some reason. When SPF protection is activated for a domain, a special record is made for it in the Domain Name System and all the DNS servers worldwide get it. The record contains all of the e-mail servers that are allowed to send legitimate messages from an address within the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and in case its sending server is permitted, the message is forwarded to the target receiver. When, however, the sending server is not included in the SPF record for the specified domain, the message won't be sent and it will be removed. Whenever you use this solution, it will stop third parties from sending spam emails that seem to have been sent from you.

SPF Protection in Shared Web Hosting

SPF protection can be activated for every domain hosted in a shared web hosting account on our cloud hosting platform with only a couple of clicks. The function is available in the Emails section of our modern Hepsia Control Panel and all it takes to enable it is to choose one of your domains from the drop-down list and type in the hostnames together with the IPv4 or IPv6 addresses of the e-mail servers that will be authorized to send email messages from your email addresses. As an added option you can even restrict the emails to be sent from your domain only if it has our MX records, i.e. if our servers handle the email addresses for it, not some third-party provider. This option will give you the top level of security, but it is not applicable if only your website is on our servers while your e-mail addresses for the domain are managed in another place. In either case, the SPF protection service will keep your email addresses risk-free from being used for spam or scam purposes.
