Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called email spoofing where an email message can be sent from one email address, but to appear as being sent from another, generally with the idea to fraud the recipient for some reason. When SPF protection is activated for a domain name, a unique record is created for it in the Domain Name System and all DNS servers around the world have it. The record features all of the email servers that are allowed to send valid messages from an address within the domain. When an email is sent, the first DNS server it goes to verifies the SPF record and when its sending server is permitted, the message is sent to the target receiver. If, however, the sending server is not contained in the SPF record for the given domain, the email message will not be sent and it will be discarded. In the event that you employ this solution, it will stop third parties from sending spam which appear to have been sent from you.
SPF Protection in Cloud Hosting
SPF protection can be enabled for every domain name hosted in a cloud hosting account on our cloud platform with just a couple of mouse-clicks. The feature can be found in the Emails section of our cutting-edge Hepsia Control Panel and what is needed to enable it is to select one of your domains from the drop-down menu and to type in the hostnames and the IPv4 or IPv6 addresses of the e-mail servers which will be authorized to send messages from your emails. As an additional option you may also restrict the emails to be sent from your domain only if it includes our MX records, in other words when our servers manage the email addresses for it, not some third-party provider. This option will give you the best degree of protection, but it is not applicable if only your web site is on our servers while your emails for the domain are taken care of in another place. In either case, the SPF protection service will keep your email addresses safe from being used for spam and scam purposes.
