SPF, which means Sender Policy Framework, is an email protection system, which is used to validate if an email message is sent by a certified server. Employing SPF protection for a domain will prevent the forging of email addresses made with the domain. In layman's terms: activating this function for a domain generates a special record in the Domain Name System (DNS) containing the IP addresses of the servers that are allowed to send e-mails from mailboxes using the domain. As soon as this record propagates worldwide, it will exist on all DNS servers that direct the Internet traffic. Every time a new email message is sent, the first DNS server it uses verifies whether it originates from an accredited server. If it does, it's sent to the destination address, but when it does not come from a server part of the SPF record for the domain, it's rejected. In this way nobody will be able to mask an e-mail address then make it appear as if you are e-mailing spam. This method is also known as email spoofing.
SPF Protection in Hosting
You're able to enable the SPF protection option for your domains with just a couple of clicks inside the Hepsia Control Panel, which is included in all of our Linux hosting. This carried out from the section with the very same name and you can allow the protection for each domain name part of our exceptional cloud hosting platform. Using a really simple interface, all you'll need to enter is the hostname of the mail server that will be permitted to send out messages from your e-mail addresses and its IPv4 or IPv6 address. Last, but not least, you are able to include several servers as well, if needed. In case your e-mails are taken care of by us, you can also employ a more secure option by placing a restriction that e-mails can be sent only if your domain names have our MX records. This alternative can't be applied if your site is here, while the emails are with some third-party provider. Either way, the SPF protection solution can strongly enhance your online safety and prevent other people from counterfeiting your e-mail addresses.
