Sender Policy Framework, or SPF, is a validation system, which is intended to prevent the so-called email spoofing where an e-mail message is sent from one email address, but to appear as being sent from another one, ordinarily with the purpose to scam the recipient in some way. If SPF protection is activated for a domain name, a special record is created for it in the Domain Name System and all of the DNS servers around the world receive it. The record features all email servers that are permitted to send authentic messages from an e-mail address under the domain. When a message is sent, the first DNS server it goes to verifies the SPF record and if the sending server is permitted, the message is forwarded to the targeted destination. In case, however, the sending server is not contained in the SPF record for the specified domain, the e-mail message won't be forwarded and it'll be removed. In case you use this solution, it will stop third parties from sending spam emails which seem to have been sent from you.

SPF Protection in Web Hosting

You're able to enable the SPF protection service for your domains with just a couple of clicks inside the Hepsia Control Panel, which is included in all of our Linux web hosting packages. This is performed from the section bearing the very same name and you'll be able to allow the protection for each and every domain name on our leading-edge cloud platform. Using a very time and effort saving interface, all you have to enter is the hostname of the mail server which will be permitted to send out messages from your e-mails and its IPv4 or IPv6 address. Of course, you are able to add several servers as well, if needed. In case your e-mails are taken care of by us, you may also take advantage of a more secure option by putting a limit that e-mail messages can be sent only if your domain names have our MX records. This alternative can't be used in case your website is here, but your e-mails are with a third-party supplier. In either case, the SPF protection option can greatly improve your online safety and stop others from spoofing your email addresses.
