Sender Policy Framework, or SPF, is a validation system, which is employed to prevent the so-called email spoofing where an e-mail message can be sent from one e-mail, but to look as being sent from another one, usually with the idea to fraud the recipient someway. When SPF protection is enabled for a domain, a specific record is created for it in the Domain Name System and all of the DNS servers around the world get it. The record features all mail servers that are allowed to send legitimate messages from an email address part of the domain. When an email is sent, the first DNS server it encounters verifies the SPF record and when its sending server is permitted, the message is forwarded to the target receiver. When, however, the sending server doesn't exist in the SPF record for the specified domain, the e-mail message won't be forwarded and it'll be removed. In the event that you employ this service, it'll stop third parties from sending spam e-mails which seem to have been sent by you.

SPF Protection in Cloud Web Hosting

SPF protection can be activated for every domain name hosted in a cloud web hosting account on our cloud hosting platform with just a few mouse-clicks. The feature can be found in the Emails section of our revolutionary Hepsia Control Panel and what is needed to enable it is to select one of your domains from a drop-down list and to enter 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 also restrict the emails to be sent from your domain name only if it includes our MX records, i.e. when our servers handle the email addresses for it, not some third-party provider. This feature will provide you with the best standard of safety, but it's not applicable if only your website is on our servers while the e-mail addresses for the domain name are taken care of in another place. In either case, the SPF protection service will keep your emails safe from being used for spam and scam purposes.
