SPF, which stands for Sender Policy Framework, is an email security system, that is employed to validate whether an email message is sent by a certified server. Using SPF protection for a particular domain will stop the counterfeiting of emails created with the domain. In layman's terms: enabling this function for a domain generates a specific record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send e-mail messages from mailboxes using the domain. The moment this record propagates worldwide, it will exist on all DNS servers that route the Internet traffic. When some email message is sent, the first DNS server it goes through tests if it originates from an approved server. If it does, it's forwarded to the destination address, yet if it does not come from a server part of the SPF record for the domain, it is discarded. Thus nobody will mask an email address and make it appear as if you are e-mailing spam messages. This method is also known as email spoofing.
SPF Protection in Web Hosting
You can activate the SPF protection option for your domain names with only a couple of clicks inside the Hepsia Control Panel, which comes with all our Linux web hosting. This carried out via the section with the same name and you are able to allow the protection for each and every domain hosted on our advanced cloud hosting platform. Using a very convenient interface, all you'll need to type in is the hostname of the mail server that will be accredited to send out messages from your e-mails and its IPv4 or IPv6 address. Last, but not least, you'll be able to add several servers as well, when needed. In case your email addresses are handled on our end, you can also take advantage of an even more risk-free option by placing a restriction that messages can be sent only if your domain names feature our MX records. This alternative cannot be applied when your website is here, while the emails are with a third-party service provider. In either case, the SPF protection option can definitely enhance your web security and stop other people from forging your e-mail addresses.
