Sender Policy Framework, or SPF, is a verification system, that is designed to prevent the so-called email spoofing where an email message can be sent from one e-mail address, but to appear as being sent from another one, often with the idea to scam the recipient for some reason. When SPF protection is enabled for a domain, a unique record is generated for it in the Domain Name System and all the DNS servers globally have it. The record contains all email servers that are permitted to send valid messages from an address within the domain. When an e-mail is sent, the first DNS server it goes to verifies the SPF record and if its sending server is permitted, the message is forwarded to the targeted receiver. If, however, the sending server is not included in the SPF record for the particular domain, the message won't be forwarded and it will be discarded. In case you employ this solution, it'll stop third parties from sending spam that seem to have been sent by you.

SPF Protection in Website Hosting

SPF protection can be enabled for each domain name hosted in a website hosting account on our cloud platform with no more than a couple of mouse-clicks. The function is available in the Emails section of our exceptional Hepsia Control Panel and all it takes to enable it is to pick one of your domains from the drop-down list and then enter the hostnames plus the IPv4 or IPv6 addresses of the e-mail servers that will be permitted to send email messages from your email addresses. As an added option you may also restrict the emails to be sent from your domain only if it includes our MX records, in other words if our servers handle the emails for it, not a third-party provider. This option provides you with the highest degree of security, but it's not applicable in case only your web site is on our servers while the e-mail addresses for the domain are managed elsewhere. Either way, the SPF protection service will keep your email addresses safe from being used for spam and scam purposes.
