SPF, which is short for Sender Policy Framework, is an e-mail security system, that is is intended to verify whether an e-mail message is sent by an authorized server. Employing SPF protection for a given domain name will stop the faking of emails generated with the domain. In layman's terms: enabling this function for a domain name creates a special record in the Domain Name System (DNS) which contains the IP addresses of the servers which are permitted to send e-mails from mailboxes under the domain. When this record propagates globally, it will exist on all of the DNS servers that direct the Internet traffic. Any time an email message is sent, the first DNS server it uses tests if it comes from an accredited server. In the event it does, it's forwarded to the destination address, but when it doesn't originate from a server part of the SPF record for the domain, it's discarded. Thus nobody will mask an email address then make it appear as if you're sending spam. This technique is also called email spoofing.

SPF Protection in Web Hosting

You are able to activate the SPF protection option for your domain names with just a couple of clicks inside the Hepsia Control Panel, which comes with all of our Linux web hosting packages. This carried out through the section with an identical name and you'll be able to enable the protection for any domain on our modern cloud hosting platform. Using a very simple interface, all you need to enter is the hostname of the mail server which will be permitted to send messages from your e-mail addresses and its IPv4 or IPv6 address. Of course, you're able to include several servers as well, when needed. In case your e-mails are handled on our end, you may also employ a more risk-free option by placing a limit that emails can be sent only when your domain names feature our MX records. This option cannot be applied if your web site is hosted here, while the emails are with a third-party supplier. Either way, the SPF protection option will strongly enhance your online security and stop other people from forging your email addresses.
