Sender Policy Framework, or SPF, is a validation system, which is designed to prevent the so-called email spoofing where an e-mail message is sent from one address, but to seem as being sent from a different one, typically with the idea to scam the recipient in some way. When SPF protection is activated for a domain, an exclusive record is generated for it in the Domain Name System and all the DNS servers globally receive it. The record contains all of the e-mail servers that are permitted to send legitimate messages from an email address within the domain. When a message is sent, the very first DNS server it encounters checks the SPF record and when its sending server is authorized, the message is sent to the targeted receiver. When, however, the sending server doesn't exist in the SPF record for the given domain, the e-mail message won't be sent and it'll be discarded. When you employ this service, it'll stop third parties from sending spam e-mails that appear to have been sent from you.

SPF Protection in Cloud Hosting

SPF protection can be activated for every domain hosted in a cloud hosting account on our cloud platform with only a few clicks. The option is available in the Emails section of our exceptional Hepsia Control Panel and what is needed to activate it is to choose one of your domains from the drop-down menu and then enter the hostnames together with the IPv4 or IPv6 addresses of the e-mail servers that will be certified to send messages from your email addresses. As an added option you may also restrict the email messages to be sent from your domain name only if it has our MX records, in other words when our servers manage the emails for it, not some third-party provider. This feature gives you the highest standard of protection, but it is not applicable in case only your website is on our servers while the emails for the domain name are handled elsewhere. Regardless, our SPF protection service will keep your emails protected from being used for spam and/or scam purposes.
