SPF, which stands for Sender Policy Framework, is an e-mail protection system, that is is intended to verify if an email message is sent by an authorized server. Employing SPF protection for a domain name will stop the forging of email addresses created with the domain. In simple words: activating this attribute for a domain makes a particular record in the Domain Name System (DNS) that contains the IP addresses of the servers that are permitted to send e-mail messages from mailboxes under the domain. As soon as this record propagates worldwide, it exists on all the DNS servers that direct the Internet traffic. Any time some e-mail message is sent, the first DNS server it uses tests whether it comes from an accredited server. When it does, it's forwarded to the destination address, yet when it doesn't come from a server indexed in the SPF record for the particular domain, it's rejected. Thus nobody will be able to mask an email address then make it appear as if you are sending spam messages. This approach is also referred to as email spoofing.

SPF Protection in Hosting

You are able to enable the SPF protection option for your domains with a couple of clicks inside the Hepsia Control Panel, which comes with all our hosting plans. This is performed through the section bearing an identical name and you're able to allow the protection for each domain hosted on our modern cloud platform. Using a very user-friendly interface, all you will have to type in is the hostname of the mail server which will be permitted to send messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, it is possible to include several servers as well, if needed. If your e-mails are taken care of by us, you may also use an even more secure option by placing a restriction that messages can be sent only if your domains feature our MX records. This alternative can't be applied when your site is hosted with us, while the e-mails are with some third-party service provider. In either case, the SPF protection option will really improve your online safety and prevent other people from forging your e-mail addresses.
