Sender Policy Framework, or SPF, is a verification system, that is used to stop the so-called email spoofing where an e-mail message can be sent from one email address, but to seem as being sent from another, generally with the purpose to scam the recipient for some reason. If SPF protection is activated for a domain, a specific record is created for it in the Domain Name System and all the DNS servers around the world have it. The record includes all the mail servers that are permitted to send authentic messages from an email address within the domain. When an email is sent, the 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 present in the SPF record for the specified domain, the email message will not be forwarded and it'll be discarded. In the event that you use this solution, it'll stop third parties from sending spam messages that look as if they have been sent by you.
SPF Protection in Cloud Website Hosting
SPF protection can be enabled for any domain name hosted in a cloud website hosting account on our cloud platform with just a couple of mouse-clicks. The feature can be found in the Emails section of our revolutionary Hepsia Control Panel and what is needed to activate it is to choose one of your domain names from a drop-down list and enter the hostnames plus the IPv4 or IPv6 addresses of the email servers which will be authorized to send messages from your email addresses. As an added option you can also restrict the messages to be sent from your domain name only if it has our MX records, in other words when our servers handle the email addresses for it, not a third-party provider. This feature will give you the best degree of safety, but it is not applicable when only your website is on our servers while your e-mail addresses for the domain name are taken care of elsewhere. In either case, the SPF protection service will keep your email addresses safe from being used for spam or scam purposes.
