Sender Policy Framework, or SPF, is a validation system, which is designed to stop the so-called e-mail spoofing where an e-mail message can be sent from one e-mail address, but to appear as being sent from a different, often with the objective to scam the recipient for some reason. If SPF protection is enabled for a domain, an exclusive record is generated for it in the Domain Name System and all DNS servers worldwide get it. The record contains all e-mail servers that are allowed to send legitimate messages from an email address under the domain. When an email is sent, the very first DNS server it encounters checks the SPF record and in case its sending server is authorized, the message is forwarded to the targeted receiver. In case, however, the sending server is not contained in the SPF record for the given domain, the email message won't be sent and it'll be removed. In the event that you employ this solution, it will stop third parties from sending spam emails that appear to have been sent by you.

SPF Protection in Web Hosting

SPF protection can be activated for any domain hosted in a web hosting account on our cloud hosting platform with just a few clicks. The option is available in the Emails section of our outstanding Hepsia Control Panel and what is needed to enable it is to pick one of your domains from a drop-down menu and to enter the hostnames and the IPv4 or IPv6 addresses of the mail servers which will be approved to send emails from your email addresses. As an added option you can even restrict the emails to be sent from your domain only if it includes our MX records, i.e. when our servers handle the emails for it, not a third-party supplier. This option will give you the best standard of protection, but it is not applicable if only your site is on our servers while your emails for the domain are handled elsewhere. In either case, the SPF protection service will keep your email addresses safe from being used for spam and/or scam purposes.
