Sender Policy Framework, or SPF, is a validation system, that is designed to stop the so-called e-mail spoofing where an email message is sent from one e-mail, but to appear as being sent from a different, frequently with the objective to fraud the recipient in some way. If SPF protection is activated for a domain name, a special record is generated for it in the Domain Name System and all DNS servers globally receive it. The record contains all of the e-mail servers that are allowed to send valid messages from an e-mail address within the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and if the sending server is permitted, the message is forwarded to the target destination. When, however, the sending server is not included in the SPF record for the given domain, the email message will not be forwarded and it'll be removed. In the event that you employ this solution, it will prevent third parties from sending spam that appear to have been sent from you.

SPF Protection in Hosting

If you host your domain names in a hosting account with us and we manage the e-mails for them, you are able to enable SPF protection for any of them with a few clicks in your Hepsia Control Panel. This service can be found in a separate section where you are able to see which domains are already secured. For those that aren't, you will be able to enable the SPF protection service and configure a lot of things during the process - the hostnames of the mail servers that are permitted to send messages from your e-mail addresses, the IPv4 and IPv6 addresses of these servers, as well as to create a rule that emails can be sent only if your domains include our MX records. The aforementioned option is the most secure one, and it can be used if we take care of the e-mails for your domain names and you're not using another e-mail supplier. The new records will be activated within 24 hours and nobody will be able to fake the FROM field in a message with your email addresses.

SPF Protection in Semi-dedicated Servers

If you have a semi-dedicated server account with us, you'll be able to secure your email addresses by activating 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 the Hepsia Control Panel which is included with the semi-dedicated accounts and even if you have no previous practical experience with these issues, you will not have any kind of trouble to enable the security. All that you will have to do is to choose a domain from a drop-down list and then type the mail server hostname and IPv4 or IPv6 address. When the updated record propagates, messages from your emails will be mailed around the world only if they are sent from that particular server. In case 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 e-mail messages to be sent only when the domain name has our MX records and this would be the safest option. When you have any questions related to thisfeature, you will be able to get in touch with our support team 24/7.
