Sender Policy Framework, or SPF, is a verification system, which is used to prevent the so-called e-mail spoofing where an e-mail message is sent from one email, but to look as being sent from a different one, often with the idea to fraud the recipient in some way. If SPF protection is activated for a domain, a unique record is created for it in the Domain Name System and all the DNS servers worldwide receive it. The record includes all of the email servers that are allowed to send valid messages from an e-mail address part of the domain. When an email is sent, the very first DNS server it goes to verifies the SPF record and if its sending server is permitted, the message is sent to the targeted destination. In case, however, the sending server is not included in the SPF record for the particular domain, the email message will not be submitted and it will be removed. If you employ this service, it'll stop third parties from sending spam which appear to have been sent by you.

SPF Protection in Cloud Web Hosting

SPF protection can be activated for each domain name hosted in a cloud web hosting account on our cloud platform with just a few mouse-clicks. The option can be found in the Emails section of our cutting-edge Hepsia Control Panel and all you need to enable it is to pick one of your domain names from the drop-down list and to enter the hostnames as well as the IPv4 or IPv6 addresses of the e-mail servers that will be authorized to send email messages from your emails. As an added option you can even restrict the messages to be sent from your domain name only when it has our MX records, in other words when our servers handle the emails for it, not some third-party provider. This solution will provide you with the best degree of protection, but it's not applicable when only your website is on our servers while the e-mail addresses for the domain name are handled in a different place. Regardless, our SPF protection service will keep your email addresses protected from being used for spam and scam purposes.
