Sender Policy Framework, or SPF, is a verification system, which is employed to prevent the so-called email spoofing where an email message is sent from one e-mail address, but to seem as being sent from a different, usually with the purpose to fraud the recipient for some reason. When SPF protection is activated for a domain, a specific record is made for it in the Domain Name System and all the DNS servers worldwide have it. The record contains all the email servers that are permitted to send legitimate messages from an address under the domain. When an e-mail 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 targeted destination. In case, however, the sending server is not present in the SPF record for the specified domain, the e-mail message will not be sent and it'll be removed. If you employ this service, it will prevent third parties from sending spam messages which appear to have been sent from you.

SPF Protection in Cloud Hosting

SPF protection can be enabled for any domain hosted in a cloud hosting account on our cloud hosting platform with only a couple of mouse-clicks. The function is available in the Emails section of our cutting-edge Hepsia Control Panel and all you need to enable it is to choose one of your domain names from a drop-down list and to enter the hostnames together with the IPv4 or IPv6 addresses of the mail servers which will be certified to send emails from your emails. As an additional option you can even restrict the messages to be sent from your domain name only when it includes our MX records, in other words if our servers handle the email addresses for it, not a third-party provider. This option will give you the best level of protection, but it is not applicable if only your site is on our servers while your email addresses for the domain name are managed elsewhere. Either way, the SPF protection service will keep your email addresses secure from being used for spam or scam purposes.
