SPF, which means Sender Policy Framework, is an e-mail protection system, that is is intended to confirm whether an email message is sent by a licensed server. Employing SPF protection for a particular domain name will prevent the faking of email addresses created with the domain. In layman's terms: activating this attribute for a domain makes a particular record in the Domain Name System (DNS) that contains the IP of the servers that are permitted to send e-mail messages from mailboxes under the domain. The moment this record propagates worldwide, it exists on all of the DNS servers that direct the Internet traffic. Any time an email message is sent, the initial DNS server it goes through checks whether it comes from an approved server. When it does, it is sent to the destination address, however when it does not come from a server listed in the SPF record for the domain, it's discarded. In this way nobody can mask an e-mail address to make it appear as if you're sending spam messages. This method is also termed email spoofing.

SPF Protection in Semi-dedicated Servers

When you have a semi-dedicated server account from our company, you are able to secure your emails by enabling the SPF protection service for any domain in your account with only a couple of mouse-clicks. This is done in the Emails section of the Hepsia Control Panel that is provided with the semi-dedicated accounts and even if you have no previous practical experience with these kinds of issues, you won't have any kind of trouble to activate the security. The only things that you'll have to do is to choose a domain from a drop-down menu then type in the mail server hostname and IPv4 or IPv6 address. Once the updated record propagates, messages from your emails will be mailed around the world only if they're sent from that particular server. If your emails are handled by our company and not by a third-party provider, you'll also be able to benefit from an option for email messages to be sent only if the domain name has our MX records and the latter is the most secure option. If you have any questions related to thisfeature, you'll be able to contact our support team 24/7.
