Sender Policy Framework, or SPF, is a verification system, which is employed to prevent the so-called e-mail spoofing where an email message can be sent from one address, but to seem as being sent from another, often with the idea to fraud the recipient someway. If SPF protection is enabled for a domain, a unique record is made for it in the Domain Name System and all DNS servers worldwide have it. The record contains all the email servers that are permitted to send legitimate messages from an address within the domain. When an email is sent, the very first DNS server it goes to checks the SPF record and when its sending server is authorized, the message is sent to the target destination. In case, however, the sending server is not present in the SPF record for the specified domain, the email message won't be forwarded and it will be removed. When you use this solution, it will prevent third parties from sending spam messages that seem to have been sent from you.

SPF Protection in Cloud Web Hosting

SPF protection can be enabled for each domain name hosted in a cloud web hosting account on our cloud platform with just a couple of clicks. The feature is available in the Emails section of our advanced Hepsia Control Panel and all you need to enable it is to select one of your domain names from the drop-down menu and then type in the hostnames plus the IPv4 or IPv6 addresses of the email servers that will be approved to send email messages from your emails. As an added option you can also restrict the messages to be sent from your domain only if it has our MX records, i.e. when our servers handle the e-mail addresses for it, not a third-party provider. This feature gives you the highest degree of protection, but it's not applicable if only your web site is on our servers while the email addresses for the domain are handled elsewhere. Regardless, our SPF protection service will keep your email addresses secure from being used for spam and scam purposes.
