Sender Policy Framework, or SPF, is a validation system, that is designed to stop the so-called email spoofing where an e-mail message is sent from one email address, but to seem as being sent from another, frequently with the purpose to scam the recipient for some reason. If SPF protection is activated for a domain name, a unique record is generated for it in the Domain Name System and all the DNS servers globally receive it. The record contains all mail servers that are permitted to send legitimate messages from an e-mail address under the domain. When an e-mail is sent, the very first DNS server it encounters verifies the SPF record and if its sending server is permitted, the message is sent to the target receiver. In case, however, the sending server doesn't exist in the SPF record for the specified domain, the message will not be submitted and it will be discarded. If you use this service, it'll prevent third parties from sending spam e-mails that seem to have been sent from you.

SPF Protection in Cloud Hosting

SPF protection can be enabled for any domain name hosted in a cloud hosting account on our cloud hosting platform with just a couple of mouse-clicks. The feature is accessible in the Emails section of our outstanding Hepsia Control Panel and all it takes to use it is to pick one of your domains from the drop-down list and to type in the hostnames plus the IPv4 or IPv6 addresses of the email servers which will be permitted to send messages from your email addresses. As an additional option you can even restrict the e-mails to be sent from your domain name only if it includes our MX records, in other words when our servers manage the email addresses for it, not some third-party provider. This solution provides you with the highest standard of security, but it is not applicable if only your website is on our servers while your email addresses for the domain name are managed somewhere else. Either way, the SPF protection service will keep your emails safe from being used for spam and/or scam purposes.
