Sender Policy Framework, or SPF, is a validation system, that is designed to stop the so-called email spoofing where an email message can be sent from one e-mail, but to appear as being sent from another one, often with the idea to fraud the recipient in some way. When SPF protection is activated for a domain, an exclusive record is made for it in the Domain Name System and all the DNS servers globally receive it. The record features all mail servers that are allowed to send valid messages from an e-mail address within the domain. When a message is sent, the very first DNS server it encounters verifies the SPF record and if its sending server is authorized, the message is sent to the target receiver. When, however, the sending server is not present in the SPF record for the given domain, the email message won't be sent and it'll be removed. When you employ this service, it'll stop third parties from sending spam e-mails that appear to have been sent from you.

SPF Protection in Cloud Hosting

SPF protection can be enabled for each domain hosted in a cloud hosting account on our cloud hosting platform with just a few mouse-clicks. The feature is accessible in the Emails section of our leading-edge Hepsia Control Panel and all you need to use it is to pick one of your domain names from a drop-down menu and to type in the hostnames as well as the IPv4 or IPv6 addresses of the e-mail servers that will be approved to send email messages from your emails. As an additional option you can even restrict the emails to be sent from your domain name only if it includes our MX records, in other words if our servers handle the emails for it, not some third-party supplier. This feature will provide you with the best standard of security, but it's not applicable in case only your web site is on our servers while the emails for the domain name are handled somewhere else. Regardless, our SPF protection service will keep your email addresses secure from being used for spam or scam purposes.
