SPF, which is an acronym for Sender Policy Framework, is an email protection system, which is employed to verify if an email message was sent by an official server. Employing SPF protection for a given domain will prevent the counterfeiting of email addresses made with the domain. In simple words: activating this function for a domain generates a specific record in the Domain Name System (DNS) containing the IP of the servers that are allowed to send e-mail messages from mailboxes under the domain. As soon as this record propagates worldwide, it will exist on all of the DNS servers that direct the Internet traffic. Every time an email message is sent, the initial DNS server it uses checks whether it originates from an official server. When it does, it is sent to the destination address, however when it doesn't originate from a server part of the SPF record for the domain, it's discarded. Thus nobody will be able to mask an email address then make it appear as if you're distributing spam messages. This technique is also referred to as email spoofing.

SPF Protection in Shared Web Hosting

You can enable the SPF protection service for your domain names with just a few clicks inside the Hepsia Control Panel, which comes with all our shared web hosting. This is done from the section bearing the same name and you'll be able to enable the protection for each and every domain on our leading-edge cloud platform. Using a really time and effort saving interface, all you will have to enter is the hostname of the mail server that will be approved to send out messages from your email addresses and its IPv4 or IPv6 address. Last, but not least, you can include several servers as well, if needed. In case your emails are taken care of by us, you may also employ a more secure option by placing a restriction that e-mail messages can be sent only if your domains include our MX records. This option cannot be used if your site is hosted here, while your e-mails are with some third-party provider. Either way, the SPF protection solution will tremendously improve your online security and stop other people from forging your e-mail addresses.
