Sender Policy Framework, or SPF, is a validation 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 one, generally with the idea to scam the recipient in some way. If SPF protection is activated for a domain, an exclusive record is made for it in the Domain Name System and all DNS servers worldwide have it. The record contains all mail servers that are allowed to send legitimate messages from an address under the domain. When a message is sent, the very first DNS server it encounters verifies the SPF record and in case the 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 specified domain, the e-mail message won't be forwarded and it will be removed. In case you use this solution, it will prevent third parties from sending spam emails that appear to have been sent from you.

SPF Protection in Shared Hosting

SPF protection can be enabled for every domain hosted in a shared hosting account on our cloud platform with just a couple of mouse-clicks. The feature is available in the Emails section of our cutting-edge Hepsia Control Panel and all it takes to enable it is to pick one of your domains from a drop-down menu and to enter the hostnames as well as the IPv4 or IPv6 addresses of the e-mail servers which will be approved to send email messages from your emails. As an additional option you can also restrict the emails to be sent from your domain only when it has our MX records, i.e. when our servers handle the e-mail addresses for it, not a third-party supplier. This feature gives you the highest standard of security, but it is not applicable if only your site is on our servers while your e-mail addresses for the domain are taken care of somewhere else. In either case, the SPF protection service will keep your email addresses safe from being used for spam and scam purposes.
