SPF, which is short for Sender Policy Framework, is an e-mail security system, which is is intended to verify whether an e-mail message was sent by an authorized server. Employing SPF protection for a particular domain will prevent the faking of email addresses created with the domain. In layman's terms: enabling this attribute for a domain name generates a specific record in the Domain Name System (DNS) which includes the IP of the servers which are permitted to send e-mail messages from mail boxes using the domain. When this record propagates worldwide, it will exist on all DNS servers that route the Internet traffic. When an email message is sent, the first DNS server it goes through tests whether it originates from an official server. In the event it does, it's sent to the destination address, yet if it doesn't come from a server indexed in the SPF record for the domain, it is discarded. In this way nobody can mask an e-mail address then make it look as if you're e-mailing spam messages. This technique is also known as email spoofing.

SPF Protection in Cloud Hosting

SPF protection can be activated for each domain hosted in a cloud hosting account on our cloud hosting platform with just a couple of mouse-clicks. The function can be found in the Emails section of our outstanding Hepsia Control Panel and all it takes to use it is to choose one of your domain names from a drop-down list and to type in the hostnames plus the IPv4 or IPv6 addresses of the mail servers that will be permitted to send emails from your emails. As an additional option you can even restrict the e-mails to be sent from your domain name only if it has our MX records, i.e. when our servers handle the email addresses for it, not a third-party supplier. This solution will give you the best level of safety, but it's not applicable in case only your web site is on our servers while the email addresses for the domain name are taken care of in a different place. Either way, the SPF protection service will keep your email addresses protected from being used for spam and scam purposes.

SPF Protection in Semi-dedicated Servers

If you have a semi-dedicated server account from our company, you can secure your emails by activating the SPF protection service for any domain name hosted in the account with only a couple of mouse-clicks. This is done in the Emails section of our Hepsia Control Panel that is included with the semi-dedicated accounts and even if you lack previous practical experience with these issues, you will not have any kind of troubles to activate the protection. All that you'll have to do will be to find a domain from a drop-down menu and then type the mail server hostname and IPv4 or IPv6 address. The moment the new record propagates, messages from your emails will be mailed globally only if they are sent from that particular server. If your e-mail addresses are managed by our company and not by some third-party supplier, you can also use an option for e-mail messages to be mailed only when the domain name contains our MX records and the latter would be the most secure option. If you have any questions about thisfunction, you can contact our support team 24/7.
