SPF, which is an acronym for Sender Policy Framework, is an e-mail safety system, which is employed to confirm whether an email message was sent by an authorized server. Using SPF protection for a domain will prevent the faking of email addresses generated with the domain. In simple words: activating this function for a domain name makes a particular record in the Domain Name System (DNS) which contains the IP addresses of the servers which are allowed to send emails from mailboxes under the domain. Once this record propagates globally, it exists on all the DNS servers that direct the Internet traffic. Any time a new email message is sent, the first DNS server it goes through verifies if it comes from an accredited server. In the event it does, it's forwarded to the destination address, yet when it does not originate from a server part of the SPF record for the domain, it's discarded. Thus nobody will mask an e-mail address and make it look as if you're e-mailing spam. This technique is also referred to as email spoofing.

SPF Protection in Cloud Web Hosting

You can enable the SPF protection option for your domains with just a few clicks inside the Hepsia Control Panel, which comes with all our Linux cloud web hosting. This is performed through the section bearing the very same name and you can set up the protection for each and every domain part of our revolutionary cloud hosting platform. Using a really time and effort saving interface, all you have to type in is the hostname of the mail server which will be accredited to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Of course, you are able to add several servers too, if needed. When your e-mail addresses are handled by us, you can also use a more risk-free option by placing a limit that emails can be sent only when your domain names include our MX records. This solution can't be applied in case your website is here, while your email addresses are with some third-party provider. In either case, the SPF protection option can significantly enhance your web safety and prevent other people from forging your e-mail addresses.
