SPF, which stands for Sender Policy Framework, is an email security system, which is employed to validate if an e-mail message is sent by a certified server. Using SPF protection for a domain will stop the counterfeiting of email addresses generated with the domain. In layman's terms: activating this attribute for a domain name makes a special record in the Domain Name System (DNS) containing the IP of the servers that are allowed to send emails from mailboxes using the domain. As soon as this record propagates globally, it exists on all the DNS servers that direct the Internet traffic. Every time an email message is sent, the initial DNS server it uses verifies whether it originates from an accredited server. When it does, it is forwarded to the destination address, but when it does not come from a server part of the SPF record for the particular domain, it's rejected. Thus nobody can mask an e-mail address then make it appear as if you're e-mailing spam. This method is also identified as email spoofing.
SPF Protection in Cloud Hosting
You are able to enable the SPF protection service for your domain names with a few clicks in the Hepsia Control Panel, which is provided with our Linux cloud hosting. This is performed from the section with the same name and you're able to set up the protection for any domain name hosted on our leading-edge cloud platform. Using a really convenient interface, all you have to type in is the hostname of the mail server that will be approved to send messages from your emails and its IPv4 or IPv6 address. Of course, you are able to add several servers as well, when needed. If your email addresses are handled on our end, you can also employ a more secure option by putting a limit that e-mail messages can be sent only when your domain names include our MX records. This solution cannot be used if your website is hosted with us, but your e-mails are with some third-party provider. Either way, the SPF protection solution will definitely increase your online safety and stop other people from counterfeiting your e-mail addresses.
