SPF, which is short for Sender Policy Framework, is an email security system, which is employed to confirm if an email message is sent by a licensed server. Using SPF protection for a particular domain will stop the counterfeiting of emails created with the domain. In simple words: enabling this function for a domain name generates a specific record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send e-mail messages from mail boxes under the domain. Once this record propagates globally, it will exist on all of the DNS servers that route the Internet traffic. Every time some e-mail message is sent, the first DNS server it goes through checks whether it originates from an authorized server. If it does, it is forwarded to the destination address, yet when it does not come from a server part of the SPF record for the particular domain, it is discarded. In this way nobody can mask an email address and make it appear as if you are sending spam. This technique is also known as email spoofing.

SPF Protection in Web Hosting

If you host your domain names in a web hosting account with us and we handle the email addresses for them, you are able to enable SPF protection for them with a few clicks inside your Hepsia Control Panel. The service is accessible in a section of its own where you'll be able to see which domains are already secured. For those which aren't, you will be able to enable the SPF protection service and manage various things during this process - the hostnames of the mail servers that are permitted to send messages from your addresses, the IPv4 and IPv6 addresses of the servers, and even to set a rule that messages can be sent only when your domains include our MX records. The last solution is the most secure one, and you can use it if we manage the emails for your domain names and you're not using another e-mail supplier. The newly generated records will be activated within 1 day and nobody will be able to forge the FROM field in an e-mail with your e-mail addresses.

SPF Protection in Semi-dedicated Servers

If you have a semi-dedicated server account with us, you can protect your emails by enabling the SPF protection service for any domain name hosted in your account with only a few mouse-clicks. This can be done through the Emails section of our Hepsia Control Panel which is provided with the semi-dedicated accounts and even if you have no previous experience with these matters, you will not have any kind of difficulties to activate the protection. The only things that you'll need to do is to choose a domain from a drop-down menu and after that type in the mail server hostname and IPv4 or IPv6 address. As soon as the new record propagates, messages from your e-mail addresses will be sent around the world only if they were sent from that particular server. When your email addresses are managed by us and not by some third-party supplier, you'll also be able to use an option for emails to be sent only if the domain has our MX records and the latter is the safest option.
