SPF, which is short for Sender Policy Framework, is an email security system, which is designed to verify if an email message was sent by an authorized server. Employing SPF protection for a particular domain will stop the faking of email addresses made with the domain. In layman's terms: enabling this attribute for a domain makes a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers which are allowed to send emails from mail boxes using the domain. As soon as this record propagates globally, it exists on all DNS servers that direct the Internet traffic. Any time an e-mail message is sent, the initial DNS server it goes through verifies if it comes from an authorized server. When it does, it's sent to the destination address, yet when it does not come from a server listed in the SPF record for the domain, it's discarded. In this way nobody will be able to mask an email address and make it look as if you are e-mailing spam. This approach is also identified as email spoofing.
SPF Protection in Shared Web Hosting
You're able to enable the SPF protection option for your domains with a few clicks from the Hepsia Control Panel, which is included in all of our shared web hosting. This is done through the section bearing an identical name and you're able to enable the protection for each domain name on our hi-tech cloud hosting platform. Using a very intuitive interface, all you have to submit is the hostname of the mail server that will be permitted to send out messages from your emails and its IPv4 or IPv6 address. Of course, you'll be able to include several servers too, when needed. In case your e-mail addresses are managed by us, you can also employ a more secure option by setting a restriction that messages can be sent only if your domains have our MX records. This solution can't be used when your site is hosted here, but the e-mails are with a third-party service provider. Either way, the SPF protection solution can vastly enhance your online security and stop other people from spoofing your email addresses.
