SPF, which is short for Sender Policy Framework, is an email security system, which is is intended to validate whether an e-mail message is sent by a certified server. Employing SPF protection for a particular domain name will stop the faking of emails made with the domain. In simple words: activating this attribute for a domain creates a particular record in the Domain Name System (DNS) which includes the IP of the servers that are allowed to send email 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. Every time an e-mail message is sent, the initial DNS server it goes through tests if it comes from an approved server. If it does, it's sent to the destination address, yet when it does not come from a server listed in the SPF record for the domain, it is discarded. In this way nobody will be able to mask an e-mail address to make it appear as if you are distributing spam. This method is also called email spoofing.

SPF Protection in Cloud Website Hosting

When you host your domains in a cloud website hosting account on our end and we handle the e-mail addresses for them, you are able to enable SPF protection for them with a couple of clicks in your Hepsia Control Panel. This service is accessible in its own section where you're able to see which domain names are currently protected. For those that aren't, you can activate the SPF protection service and manage a number of things during the process - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, and to create a rule that emails can be sent only when your domains have our MX records. The aforementioned solution is the most secure one, and it can be used if we take care of the emails for your domains and you're not using a different email supplier. The newly created records will propagate within one day and nobody will be able to fake the FROM field in an email with your email addresses.

SPF Protection in Semi-dedicated Hosting

If you have a semi-dedicated server account from us, you will be able to secure your email addresses by activating the SPF security service for every domain hosted in your account with only a couple of mouse-clicks. You can do this from the Emails section of the Hepsia Control Panel that is included with the semi-dedicated accounts and even when you have no previous practical experience with such matters, you won't have any kind of trouble to enable the protection. The only things that you'll have to do is to find a domain name from a drop-down list and then type in the mail server hostname and IPv4 or IPv6 address. As soon as the updated record propagates, messages from your emails will be mailed around the world only if they are sent from that specific server. If your e-mail addresses are handled by our company and not by some third-party supplier, you will also be able to benefit from an option for emails to be mailed only if the domain name contains our MX records and this is the safest option.
