SPF, which is short for Sender Policy Framework, is an email security system, that is designed to validate if an email message was sent by an authorized server. Employing SPF protection for a particular domain name will stop the faking of emails made with the domain. In layman's terms: enabling this function for a domain name makes a special record in the Domain Name System (DNS) which includes the IP addresses of the servers that are allowed to send e-mail messages from mailboxes using the domain. Once this record propagates worldwide, it exists on all the DNS servers that direct the Internet traffic. Whenever some email message is sent, the first DNS server it uses checks if it comes from an official server. When it does, it is forwarded to the destination address, however when it doesn't come from a server part of the SPF record for the particular domain, it's discarded. Thus nobody will mask an e-mail address then make it look as if you're e-mailing spam messages. This approach is also termed email spoofing.

SPF Protection in Web Hosting

You're able to activate the SPF protection service for your domain names with only a few clicks from the Hepsia Control Panel, which comes with our web hosting plans. This is performed from the section with the same name and you can set up the protection for each domain name on our outstanding cloud platform. Using a really convenient interface, all you'll need to enter is the hostname of the mail server that will be accredited to send messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you are able to add several servers as well, if needed. If your e-mails are handled by us, you can also employ a more risk-free option by placing a restriction that e-mail messages can be sent only when your domains have our MX records. This alternative cannot be used in case your web site is hosted here, while your emails are with a third-party provider. Either way, the SPF protection option can definitely improve your online protection and prevent other people from forging your e-mail addresses.
