SPF, which means Sender Policy Framework, is an email security system, that is designed to verify whether an e-mail message was sent by a certified server. Using SPF protection for a domain will stop the faking of email addresses made with the domain. In simple words: enabling this attribute for a domain name creates a special record in the Domain Name System (DNS) that contains the IP of the servers that are permitted to send e-mails from mailboxes under the domain. The moment this record propagates worldwide, it exists on all DNS servers that route the Internet traffic. When some email message is sent, the initial DNS server it uses verifies whether it originates from an official server. When it does, it's forwarded to the destination address, yet if it doesn't originate from a server indexed in the SPF record for the domain, it is discarded. In this way nobody can mask an email address and make it look as if you're e-mailing spam messages. This technique is also known as email spoofing.
SPF Protection in Website Hosting
SPF protection can be activated for any domain name hosted in a website hosting account on our cloud hosting platform with no more than a few clicks. The feature can be found in the Emails section of our modern Hepsia Control Panel and all it takes to enable it is to select one of your domains from a drop-down list and type in the hostnames plus the IPv4 or IPv6 addresses of the email servers that will be authorized to send emails from your email addresses. As an added option you can also restrict the emails to be sent from your domain name only when it has our MX records, i.e. when our servers manage the emails for it, not a third-party provider. This solution provides you with the highest degree of safety, but it's not applicable in case only your website is on our servers while the email addresses for the domain name are handled in another place. Either way, our SPF protection service will keep your email addresses protected from being used for spam or scam purposes.
SPF Protection in Semi-dedicated Servers
If you have a semi-dedicated server account from us, you'll be able to protect your emails by activating the SPF protection service for any domain hosted in your account with just a couple of mouse-clicks. You can do this from the Emails section of our Hepsia Control Panel that is provided with the semi-dedicated accounts and even in case you have no previous practical experience with such matters, you will not have any trouble to enable the protection. All that you will have to do is to select a domain from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your email addresses will be sent globally only if they are sent from that server. If your email addresses are handled by us and not by some third-party provider, you'll also be able to activate an option for emails to be mailed only if the domain features our MX records and the aforementioned is the most secure option. Should you have any kind of questions about thisfunction, you'll be able to contact our support crew 24/7.
