SPF, which is an acronym for Sender Policy Framework, is an e-mail safety system, that is employed to confirm whether an e-mail message is sent by an official server. Employing SPF protection for a particular domain name will stop the counterfeiting of emails made with the domain. In layman's terms: activating this attribute for a domain makes a specific record in the Domain Name System (DNS) containing the IP addresses of the servers that are permitted to send email messages from mailboxes under the domain. As soon as this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. Any time a new email message is sent, the first DNS server it goes through checks whether it originates from an accredited server. In the event it does, it is sent to the destination address, but when it does not originate from a server indexed in the SPF record for the particular domain, it's discarded. Thus nobody can mask an email address then make it look as if you are distributing spam. This method is also identified as email spoofing.

SPF Protection in Web Hosting

You're able to enable the SPF protection option for your domains with only a few clicks from the Hepsia Control Panel, which is provided with all of our Linux web hosting packages. This carried out via the section bearing the same name and you can set up the protection for each domain name hosted on our outstanding cloud platform. Using a really simple interface, all you'll need to enter is the hostname of the mail server which will be approved to send messages from your e-mails and its IPv4 or IPv6 address. Of course, you are able to include several servers as well, if needed. In case your e-mails are managed on our end, you can also employ an even more risk-free option by placing a limit that emails can be sent only if your domain names feature our MX records. This solution cannot be used when your website is here, while your emails are with a third-party provider. In either case, the SPF protection solution can greatly improve your online safety and prevent others from counterfeiting your email addresses.
